Image sharpening

As explained in a previous blog the photograph of the robin I have chosen as a final image is a little 'soft' in its focusing of the bird's head.



Steve suggested that some 'sharpening' of the image could be applied. This will not correct a lack of focus, but give minimal changes that may improve the image.

Using Photoshop I proceeded to 'Unsharp Mask' as below:


The improvement does not cause a total re-sharpening of the image, but gives a subtle enhancement.

I believe that although it may be subtle improvement can be seen.


The 'moral' of the tale is to persevere to obtain perfectly focused images. Unfortunately with action shots of birds, animals, children sport etc... a second opportunity may not occur. This is where the use of sharpening within Photoshop can be so very useful.

That 'practice makes perfect' is a trueism in photography I am really beginning to appreciate.

Choice of photos for Exhibition

In February 2012 the class have the opportunity to display an exhibition of our photographs in the Civic Centre at Swadlincote. Each of us will display two 16 x 12 inch framed photos.

In January I had to choose my 2 photos.

From Theme 1 I considered from a choice of three
  • Barn Roof
  • Fallen Leaves
  • Spider's Web







The merits of each of these photographs is discussed in the blog of final choices of Theme 1 images. Of the three I decided to exhibit the spider's web - it is visually exciting, colourful and an unusual subject.


From Theme 2 I chose the image of the greenfinch. It is a very simple image with minimal distraction and perfect focus which should look well when enlarged. It also acts as a contrast to the spider's web image.


Both of these images should present well at this size. Both have only been minimally cropped so have a maximum number of pixels available . Severe cropping may result in an image of 'staggered lines' rather than a smooth shape. This is because the digital image is composed of a finite number of coloured squares; when cropped this number is reduced, so that with subsequent enlargement the 'squares' become apparent to the naked eye.

Both were taken at ISO 400 which is a compromise setting. However i hope that 'noise' or 'graininess' will not be too apparent.

Addendum after framing:
In fact both images printed well at this size, with minimum 'noise'. There was no evidence of pixelation. The larger size added a strength and dynamism to each image - the strengths of each image were magnified. Thus, the colours of the spider's web image were more vivid and exciting; the simplicity and honesty of the green finch image were more obvious. The 'wow' factors were increased.

I was absolutely delighted with the results, and will consider framing more of my photos at this size in future. My only limitation will be wall space!

Printing and Framing of photos for an exhibition

One of course members (Ian) has arranged for an exhibition of everyone's work to be exhibited at Swadlincote Civic Centre. We are each exhibiting 2 images for the week beginning 6th February.

The plan was to print the images at 16 x 12 inch and fit into a mounted frame.


Images:

The photos were ordered on line from 'ProAm' - http://www.proamimaging.com/



The price for each photo printed was:




Plain black frames with mountings were ordered online from 'Wilkinson's'
Process of Framing:

4 frames per box


Remove wrapping









The perspex was cleaned of all marks; the mounting was protected on clean paper, the print placed face down onto it, and attached with masking tape (specialist tape which will not mark the photograph is available).







The back of the frame was carefully replaced (Warning: Safety risk of cutting fingers on metal hinges).



And we have 2 framed photographs ready for exhibition!

T2: Final Choice with editted images.

In this blog I will exhibit the final images in my choice for Theme 2. The purpose of this theme was to discover and record the nature at Church Farm in the larger scale (compared to Theme 1). For this I planned to record images of the trees, birds and animals of the garden. The time available to produce this folio was from early September 2011 to end of January 2012,  i.e. through autumn and early winter. The photos will be shown in the time order that they were taken to reflect the change of season.
The original images have been shown in the previous blog, together with details of the camera settings used and reasons why. For each image I shall explain initially the changes that I may have made to the photo concluding with my reason for choosing this particular image.
All images have been cropped to an A3 format – 420 x 297 mm.


Dawn – 29th September 2011



This image has been cropped to remove the slightly distracting flowers in the foreground. The focal point of the image is now the open area looking out into the distance with the trees just visible through the mist. This ‘rectangular’ area gives a structure to the image. From here the eye is drawn to the half hidden sun and into the trees, and then round to the lower sections and back into the image. The overall effect is quite dreamlike and surreal. I have reduced the brightness by 10 points, but even so it is difficult to accept that this is an English autumnal scene. The colours subtly blend with each other but are never dull; the mist enhances the dreamlike quality.

I did try to remove the telephone cables within Photoshop, but decided that they were not detrimental to the image; in fact such alterations may have destroyed the quality of the image. In addition the purpose of all these photos is eventually to provide personal and visual memories – and believe me the telephone cables are associated with many memories! This is one of my favourite images.



Late Afternoon Trees – 13th November 2011



This image has been minimally cropped from the original; I have increased the vibrance by 20 points and saturation by 5 points, and applied a mild warming filter (81). This has increased the overall warm tones (reds and oranges) of the picture in an image that is dominated by (cold) blues. As explained in a previous blog the sky was beginning to have a slightly pink tinge at this time and this was my reason for trying to capture the image.

The image itself is very stark, with the leafless trees contrasting dramatically to the cloudless sky. The vertical lines of the tress enhance this effect and aid the composition of the picture; the lines move the eye upward, but the tangle of branches at the top move the eye round, and thence back into the picture.

The bold outlines of the trees led me to consider transforming the picture to a black and white image. However the lack of bright light on the individual trees meant the image produced was rather flat (see later blog comparing this image to others), whereas the blue sky gives a beauty and contrast of its own. I believe this image works well, and would be suitable to print for an exhibition, or use as a smaller print in a calendar or book.



Nuthatch – 4th December 2012




This image was produced using wireless remote control and manual focussing that was preset. As such it is a lottery whether the bird will be in focus – an inch one way or the other can be crucial. In this shot the bird is in perfect focus; the eye is clear and bright, as is the beak and peanut which provide a ‘wow’ factor for this image.

The image has been cropped to make the bird the total focus. The body fills the centre of the image with the eye being placed deliberately at the Rule of Thirds intersection. The background branches are sufficiently out of focus not to distract, and since they run parallel to the bird they enhance the composition. Also of interest to me is the fact that I think this might be a juvenile – his tummy colouring is not perfect. I know another nuthatch visits the garden (with perfect colouring) and for my memories this will personalise this bird forever. I am delighted with this photo – another definite favourite.

Taken at ISO 400 and with large cropping this image may not be perfect for exhibition at A3 size – I would need to print to check, but certainly at 10 x 8 inches or in a smaller format this image could be printed or published.



House Sparrows – 30th December 2011




As stated in a previous blog I do not apologise for including a photo of the humble house sparrow. This image has been minimally cropped so that each bird lies on an intersection of a Rule of Thirds, and the contrast has been enhanced by 15 points. The colours are complementary, and the out of focus background adds interest. I was concerned that the straight lines of the pergola might detract from the image, but being slightly out of focus this is not the case – its weathered look adds to the effect. The birds are not looking at the camera. This is not perceived wisdom, as a bird looking out of an image takes the viewer’s eye also out of the image. In this instance though the fact that they appear to be looking at each other keeps the eye within the frame – indeed it adds to the interest of the photo by its interaction. Immediately we wonder – are they communicating?

The strength of this photograph lies in its perspective – by looking down on the birds. This is something we humans seldom achieve so it opens new perspectives to us.

This image is a definite favourite – it is slightly out of the ordinary. As a memento it succeeds 100%, as I believe it does in its story. It could be exhibited or printed in a book, calendar or other smaller format.



Robin – 31st December 2011



This photo has been minimally cropped to A3 size, but required some enhancement in Photoshop. I increased the brightness by 20 points, and also applied some sharpening to the image (see separate blog).

This is a classic image of a robin – eye contact is good, jaunty head and good colouration. I have placed the head and eye at a Rule of Thirds intersection. The feeder and its supporting chains provide a circular route for the eye to follow and keep in the photo – drawing you back to the bird. The colours work well together and the out of focus green background ensures a natural feel to the photo to counteract the obvious ‘man made’ influence of the feeder.

The photograph could be improved – better light, slightly closer and better focus for the bird. However for a photograph taken on December 31st this is very good. I would not exhibit this photo, but am more than happy to use in a smaller format such as previously described.



Greenfinch – 31st December 2011



This photo is another favourite of mine. The finch is in perfect focus, looking straight at the lens and looking very challenging. (They are very argumentative birds!). It has been minimally cropped, but is otherwise unaltered from the original.

Many of the comments for the previous image – background, circle of view can be applied to this image – the viewing area and settings are identical. However this image is better: Not only is the bird in perfect focus, but is positioned almost centrally – he is definitely the ‘centre’ of attention. The subtle contrasts of yellows and greens of the bird and the background are excellent, as is the contrasting texture of the soft bird’s feathers and breast compared to the metal feeder. The simplicity of the image is its great strength – a simple story of a greenfinch visiting a garden feeder. Its choice as a memento is essential.

This image can obviously be used in a small format of a book, calendar etc. It is being displayed in an exhibition of College work in 16 x 12 inch format in February - its simplicity is enhanced in this larger format. Paul Strand’s vision for photography was to stay true to the subject, and I believe in this image I have attained that.



Great Tit – 2nd January 2012



This image has been cropped to remove the hanging rope of the feeder. Additionally I have increased the brightness by 15 points and the contrast by 8 points to freshen the image slightly.

This photo compares favourably with those of Steve Young. The bird is well focussed with good eye contact, and details of its feathers and feet can be clearly seen. However the aim is not to produce an image in a gazetteer, but one with a story to tell of the garden – this being the regular visits of great tits to the garden feeders. The body of the bird is situated centrally; the log draws the eye upwards, but the slightly out of focus leaf in the top right hand brings the eye back into the image. The contrasting textures are also essential – the soft bird, the smooth bark, rough suet and the lush greenery in the background.

This is another favourite image of mine. It could be exhibited or printed in a smaller format. It shows a narrow area of focus so that the birds are central to the image with little cropping which has proved to be a successful technique.


Birds Feeding on Suet Balls – 15th January 2012



This photo has been severely cropped to focus on the 2 birds. I have increased the brightness by 26 points and the contrast by 23 points.

My aim with this photo was to capture some of the social aspect of the birds’ behaviour at the feeders – they eat peacefully together, they squabble so that none can eat; they wait patiently, they chase each other away; plus many other activities.

The eye is initially drawn to the colour of the blue tit, to the pale suet balls and then to the tree sparrow. From there the eye may move up or down the branch, but either way it meets an intersecting branch which pulls you back to the suet balls. Similarly if you follow the pale line of the suet balls you meet a branch which will take you back in the loop to the sparrow.

As it is cropped the background is far less distracting than in the original image, and the greens of the background foliage enable the sparrow to be clearly visible. There are several contrasting textures; metal feeder and suet balls, soft birds and hard beaks, smooth bark and prickly hawthorn. Finally there is the aspect of the birds; the blue tit appears to be pausing in its feeding to look at the lens (and you), whereas the sparrow appears to be positively glaring at you!

This is a fine image of which I am proud. In the future a similar shot with more accurate focus could be attempted, especially with the improved light of spring of summer. This should enable fast shutter speeds to be used to allow capture of the birds’ movement.

This image may struggle to be exhibited at A3 size because of its severe cropping, but is certainly one for a smaller format to portray common birds feeding on a typical winter’s day.



Blackbird feeding on the ground – 16th January 2012




This image has been severely cropped; it has also had its brightness increased by 16 points and its contrast by 10 points. In doing so I have transformed a very dull and ordinary image into a good image of a blackbird.

Since ground feeding birds tend to hop around whilst feeding it was necessary to have a wide area of focus. However despite this limitation I have produced an image which I shall certainly use. The bird is in perfect focus. The eye is also focussed and the fact that the bird is looking out of the photo is not detrimental. Quite to the contrary – this shows a blackbird in its most characteristic pose; watching, waiting and listening. These birds stay like this for several seconds, often before the beak moves down to dig out a worm. This is the story of the photo – the pose I have seen so often in the garden.

The colours although not bright do not blend into a monotonous whole. The blacks and browns contrast to the hints of bright green of the grass; and within the blackbird the shades of black can be clearly seen. Of particular interest is the contrasting textures – seeds, fallen leaves, living grass, soft bird and spindly legs, and of course the concrete kerb – placing the scene immediately in a garden rather than a forest.

This image may not succeed at A3 size – the black may highlight graininess, however its structure and composition make this an image well worth displaying in this folio and printing in a smaller format.


Wood Pigeon – 16th January 2012



This image has been cropped but is otherwise unaltered from the original image. As I suspected the sunshine has brought this photo to the life.

Many of the comments about the previous image are true, but this image has extra properties. The sunlight brings the colour of the pigeon to vivid life; just as it enhances the texture of its feathers. Exceptionally clear is the head. The eye is bright, in focus, looking at the lens and also into the image. Also in focus is the beak, and this image shows clearly its vivid colours.

As with the sparrow the pigeon is not a popular bird, and within the garden this is particularly true. This image shows how beautiful these birds are, and it portrays an image of stately grace for the pigeon. The pigeons are common visitors to the garden and so should be part of my final collection of garden memories.

This image I feel is good enough to be both exhibited at A3 size, and also printed in a smaller format. It is another favourite with me – especially since the subject is slightly unusual.



Grey Squirrel – 16th January 2012


This is the final image of my selection for this theme. The image has been cropped and I have increased the vibrance by 15 points, saturation by 10 points and brightness by 20 points. In a previous blog I have explained why I chose a landscape crop rather than portrait.
This is another favourite image. The squirrel’s eye is at an intersection of the Rule of Thirds, with the body and tail filling most of the central area. The colours of the squirrel are bright and well displayed, especially the whiteness of his tummy (how does he keep that clean?).  The colours of the leaves are complementary with the green grass providing a contrast. Similarly there is a wide range of textures – soft fur of the body, coarser fur of the tail, nuts, decaying leaves and twigs and the living grass. Best of all is the pose – eating calmly, yet fully alert – appearing to watch you as the viewer but ready to move to safety immediately if necessary.
This image could be displayed in A3 or smaller format. In a separate blog I compare this to one by Heather Angel. This image of mine is the one I prefer. To me it tells a completely natural and true story. Squirrels will come into the garden and feed, they will allow you sometimes to walk towards them, but always they are alert to any danger and ready to run. This is the image of this photo, and portraying this I believe that I have again mirrored the precept of natural photography spoken of by Paul Strand.
In Conclusion
More of these images have required enhancement than in Theme 1. My aim is to keep Photoshop work to a minimum – cropping for printing and little more. Unfortunately late autumn and winter does not present the best light, and this has been a limitation in my work. However I have shown that even with this limitation good work can be produced. I have learnt a new technique for taking photos of wildlife. By using wireless remote triggering of the shutter I can ‘shoot’ the shy and sensitive visitors to my garden. With increased use my technique will improve, so that I will be able to focus tighter onto the birds and animals, and thus minimise cropping of images. Similarly the increasing light of spring and summer will allow faster shutter speeds, allowing an increased variety of shots to especially include the birds landing and taking off from their perches.

Comparison of frosted berries image with commercial images


Below is the final image I have produced of the frosted berries.




In my original blog I suggested that this could be the image for a Christmas card. When I googled “frosted berries image” various links came up including the following two:

1.      Don Beck.
The image below was available as a limited edition of 50, printed on canvas for 580 dollars





This is a very simple but effective image. When enlarged the focus for the berries is perfect with a narrow depth of field, absolutely imperative for a large image on canvas. The 3 berries dominate the picture with all leading lines taking you straight to them.


1.      Red Snapper Christmas Cards
This site produces Christmas cards which can be printed and sold for companies, individuals or charities.








This image is more similar to my own, with the great advantage for a Christmas scene of lots of unblemished snow. The composition is also similar to my own.

Which is the ‘better’ image?
To be honest I think all 3 are  very good images. My least favourite is that by Don Beck. I love to see such berries in large quantities, with red being the dominant colour. I prefer my own image to that from Red Pepper. I think mine is a stronger image, visually more challenging. The snow scene would certainly be popular for a Christmas scene, but I believe my own would be equally effective.
In conclusion – I think mine is the better image. When exhibited at a large size Don Beck’s may be the most effective, but my own image will certainly hold its own.

Comparison of squirrel image:

Below is my chosen image of a Grey Squirrel:


whereas the following image of a Grey Squirrel is taken by Heather Angel (see previous blog).



Similarities of the 2 photographs:
  • Size of squirrel
  • Pose of squirrel - eating
  • Autumnal
  • Eye contact
  • Muted colours
Differences between the 2 photographs:
  • Position of squirrel (central compared to intersection of Rule of Thirds)
  • Lighting (Heather's image appears brighter)
  • Background (grass versus leaves)
  • Heather's squirrel looks into the image, whereas mine looks out of the image 
  • My image shows the white squirrel fur to better advantage
  • Square versus portrait format
  • Perspective - Heather has taken her iamge at the same level as the squirrel
 Does my image compare favourably with Heather Angel's?

In many ways the 2 photographs are very similar but I prefer my own photograph. The squirrel and its fur are brighter and the composition is more interesting. The only feature I prefer is the eye level perspective and I shall consider using this perspective in future. As always it is personal preference.
 

T2: Final Choice - Original Images



Below are the original images I have decided to put forward into my folio for Assignment 206 – Task 1a-Theme 2. This folio concentrates primarily on images of the trees, birds and animals within my garden. These images are neither cropped nor amended.



Dawn:
P9294524; 29/9/11; 0735
f/22; ISO 400; 1/125 second; focal length 70mm

This photo looks through some trees in my garden eastwards towards Anslow village. I chose a narrow aperture to enable a large depth of field. Possibly f/16 with ISO 200 might have been preferable, but this was early in the course. The image is very bright and shows the brightness of an autumn dawn. It may need adjusting in Photoshop to reduce any glare from the sun. In addition this view has telephone cables in the background. These may possibly be removable in Photoshop.




Afternoon trees:
PB134867; 13/11/11; 1527
f/16; ISO 200; 1/80 second; focal length 40mm

This photograph was taken in autumn afternoon sunshine, and the reason I was attracted to it was the pink reflection beginning to be seen in the sky. I was also interested in the shapes of the trees, and will compare this photo to ones by Richard Muir and Ansel Adams in a separate blog. Within Photoshop I shall check if the image is suitable for conversion to black and white. Otherwise it requires minimal editing.
I used a small aperture so that the depth of field would be wide enough to allow all of the trees to be in focus. Even so I could reduce to ISO 200 and a shutter speed of 1/80th second.




Nuthatch:
PC045032; 4/12/11; 1254
f/5.5; ISO 400; 1/80 second; focal length 142mm

This is one of the first images I produced using the Wireless Remote Control Device to trigger the shutter. My inspiration for this was initially my love of these birds as they visit the garden - their acrobatics and colour compare favourably with any other bird I have seen. Additionally there are several photos of nuthatches in Steve Young's book, and in a separate blog I shall compare them.
The sky was overcast so I chose a wide aperture. ISO 400 allowed a shutter speed of 1/80th second - the slowest I felt comfortable to use. This would not freeze any flight movements of the birds, but would permit minor movements of the beak and head to remain in focus.
When I consider the randomness of shots produced with this method this is an amazingly good photograph, well focused and positioned with the added interest of the peanut in the beak.
The image will simply need cropping with no further enhancements.



House sparrows:
PC305048; 30/12/11; 1125
f/5.0; ISO 400; 1/60 second; focal length 202mm

As explained in a previous blog I like the unusual perspective of this photo - looking down on the birds. I have no issues with the choice of subject - the house sparrow. This photo shows that indeed they too are beautiful birds, and the colours are complementary in this image without becoming bland. The 2 birds looking at each other adds interest, although perceived wisdom is that the bird's eye should appear to be looking at the camera. In addition one of my aims is to produce a memento of the garden and the visiting birds. For this reason if no other hedge sparrows must be included.
Taken in late December the light was not good for this photo, but by using ISO 400 and a wide aperture I have managed a compromise shutter speed of 1/60th second.
Some slight adjustment in Photoshop may prove beneficial




Robin:
PC315076; 31/12/11; 1349
f/5.6; ISO 400; 1/60 second; focal length 300mm

This image is arguably the weakest of my selection. Eye contact with the bird is perfect, and the photo catches the familiar jauntiness for which robins are so famous. For winter the colouring is bright, but there is an element of soft focus about the head. However no selection for a theme to include birds in a garden should be without a robin, and for this reason it has been chosen. A separate blog will compare the image with one by Heather Angel.
Some sharpening and brightening may be required in Photoshop.
The reason for the soft focus is the requirement for a wide aperture (because of poor light) and hence a narrow depth of field. A similar photo on a sunny spring day would produce a sharper image.




Greenfinch:
PC315084; 31/12/11; 1401
f/5.6; ISO 400; 1/60 second; focal length 300mm

This is one of my favourite photos for this folio of images. The out of focus greenery makes a perfect background, but it is the simple greenfinch that grabs the attention. It is perfectly focused (compare to the robin taken with the same settings), and the angle of the birds head plus his eye contact provides a challenge - he intends to stay and enjoy the feast!
I have discussed the camera settings for the previous image - but the only difference is the exact position of the bird! Remote photography allows excellent shots of these shy birds - but the result is quite random.
This image requires simply cropping to the required format.





Great Tit:
P1025218; 2/1/12; 1305
f/5.0; ISO 400; 1/80 second; focal length 169mm

This is another favourite image. The great tit is feeding on a log feeder filled with suet and cropping of the final image will be essential to remove the hanging cord from view. Once done this image will look like a tree trunk where suet has been placed to attract the birds.
The background to this image proves interesting. It is sufficiently out of focus to not distract yet also can provide an interesting contrast to the smooth bark. The bird is well focused with good eye contact.
The image will require cropping and possibly some enhancement in Photoshop.





Birds on suet ball feeder:
P1155345; 15/1/12; 1209
f/4.7; ISO 200; 1/125 second; focal length 76mm

Taken using remote control again my aim here was to try to portray the more social aspects of our birds, rather than an individual image. Crowds of birds in the areas of the feeders is a common site in the garden and as such needs to be recorded.
The area covered is relatively large to enable shots of birds in various poses to be taken. Unfortunately this means that severe cropping will be required. Additionally in this shot the background is very busy and a distraction. This may also improve with cropping. I deliberately used ISO 200 so that cropping could be achieved without unsatisfactory pixelation.
There was sufficient light to permit this and a faster shutter speed of 1/125th second. I shall take further photos in this area but with a narrower focus, and with patience and improved light should produce some interesting shots.





Blackbird:
P1165361; 16/1/12; 1248
f/5.6; ISO 200; 1/100 second; focal length 102mm

Ground feeding birds are common in the garden so images were needed for this theme. As explained in a previous blog I enticed the birds to a specific spot with nuts and seeds. This image as it stands is quite dull. Once more the area of focus is very large to enable photos of birds in several positions to be taken. The use of ISO 200 once more will permit cropping to be used, but future photos with a narrower focus should lead to some stunning images.



Wood Pigeon:
P1165384; 16/1/12; 1334
f/5.6; ISO 200; 1/100 second; focal length 102mm

This photograph was taken at the same spot and time as the blackbird. The comments made previously are true here, but this image has one great advantage. The left hand pigeon is in the sunlight and when cropped the image may prove very interesting.
The image will hopefully require no other enhancement.




Grey Squirrel:
P1165413; 16/1/12; 1505
f/5.6; ISO 400; 1/60 second; focal length 45mm

An image of a grey squirrel seemed to me to be essential for this folio of images. The food had been in this spot for several days and the squirrels had begun to feed. I moved the camera by 180 degrees for this photo to maximise the afternoon light. The ISO had to be increased to 400 with a maximum shutter of 1/60th second being acceptable.
Once more I was uncertain of where the squirrel would pose, hence the wide area of focus. However the image produced is one of an interesting squirrel in perfect focus. The photo will need to be cropped and may need enhancing in Photoshop. However for all its potential limitations this too is a favourite photo of mine, and I shall compare it to one produced by Heather Angel in a separate blog.
