Assignment 2 - Seeing like your camera.


Assignment Two.

Seeing Like Your Camera.

The Brief.

The assignment revolves around high-contrast scenes. You will need to produce a set of three images for each of the four situations that you choose that demonstrate that you can pre-visualise how your digital camera ‘sees’ a scene. The ability to anticipate how your camera sensor will render a scene will help you produce higher quality images which will need less post-processing.

Throughout working on the exercises that precede this assignment I have always had it at the back of my mind. I put a lot of thought into the subjects I would shoot and like to have a running theme between my images. To cover the variety of situations mentioned in the brief I decided I would ideally shoot in a large town/city. This left my most realistic options as Cambridge (my nearest City) or Bury St Edmunds, a town I am not so familiar with. I decided that I wanted to explore Bury St Edmunds and hoped to naturally gather images that filled the assignment criteria whilst being a ‘tourist’. My previous assignment involved shooting at my place of work, somewhere I am very comfortable after 7 ½ years, and feel that by going somewhere less familiar I will be out of my comfort zone and will find out if this affects the images I take.

Part One.

Choose a minimum of four situations from the following models. I have highlighted my choices.

1.      Street scene in the middle of a clear, sunny day – narrow streets and high buildings which cast deep, long shadows.

2.     Indoor space in which the only available light is strong natural window light.

3.      Photographing people in the shade while the background is in the sunshine.

4.      Early morning or late evening landscapes with low angle incident light.

5.     Any backlit scene, whether in direct or indirect light.

6.     Scenes which include objects of very different reflectivity, even in flat light such as an overcast day.

7.      Indoor scenes illuminated by a single source of artificial light of high luminance e.g. a desk lamp.

8.     A scene with strong incident dappled light – these conditions are often found when photographing in a forest in a sunny day.

 

 

 

Planning the shoot.

I decided to take a week off work as I feel that I have fallen behind my time frame for completing the exercises and this assignment. I also did not want to have to rush through it and wanted the time to visit my location several times. Before shooting I visited the town to get my bearings and assess what was there and come up with potential ideas.

I was hoping for a bright sunny day so that I could fulfil the criteria, rather than wet, dull weather which is the weather we always seem to be having at the moment.

I then gave equipment some consideration. I still only have the one lens (having bought other things such as a flash), an 18-105 mm which has still served as a good all round lens. I chose not to bring the tripod with me on my first shoot as I did not think it was necessary and as a lot of walking was involved I thought that it would be more of a hindrance. I would review this decision if necessary and could always use it on my second shoot.

Before setting out I reset my camera settings making sure that I switched from RAW to JPEG as the brief instructs, wiped my memory card so that I would not run out of space, made sure my camera lens was clean, checked the memory space on my laptop so that I would have room to transfer the images over, charged the cameras battery as well as bringing along another fully charged spare battery..

The Shoot.

The shoot went as planned and I made a total of three trips over the course of a week. The first day was used to assess the area and provisionally decide on the shooting situations. I revisited two days later when the weather was much brighter which gave me high contrast scenes. By the time I had got myself organised it was nearly the middle of the day and the sun was at its highest making shooting more of a challenge. I did find this a lot more challenging than I thought and decided to treat it as more of a learning process. I understood the brief and am reasonably good at anticipating how my camera will react but feel that the assignment did not flow as well as I had hoped.

Indoor space in which the only available light is strong natural window light.

This proved challenging from the off. I had chosen to photograph inside St Edmundsbury Cathedral as I thought that I would get some great images of the light streaming in through the large stained glass windows. This was not really the case as the sun was not strong enough to create the effects I was after. Because the sun was so weak inside the cathedral my initial images came out much darker than I was expecting. In some of the windows you could see where there were areas of highlight clipping.

 

1/60 f5.3 ISO 200 70mm

I really struggled getting a balance with these images even though I knew they would come out rather dark. I particularly liked how the candlestick had caught and reflected light from another window and had tried several different compositions to increase light level but this did not improve the situation. I have lost some of the detail from the stained glass window which is a shame. I think that having the tripod in this situation would have been beneficial as it would have allowed for a slower shutter speed and my overall image would have then been lighter. Having spoken to several people working in the cathedral I was unlucky in the time that I had chosen to shoot as the light had been much better earlier on in the day. If I was shooting here again I would experiment with different times of the day to see if this made a difference to the lighting conditions. I also think that I should have tried spot metering to see if that had given me a better exposure.

 

1/60 f4.8 ISO 1000 48mm

 
I feel that this image is much more consistent with what I was expecting from the lighting conditions. There are areas of highlight clipping in the window but I do not feel that they detract from the image as a whole. I was aiming for the light to illuminate the patterned ceiling and think that I have achieved this quite well, although there is room for improvement. I used centre weighted exposure here and I think that this has worked and given me a good exposure overall. I also needed to use a high ISO to be able to lift the scene.


1/45 f5.6 ISO 200 32mm

When trying to find the exit I walked down a long dark corridor which had these windows all along the same side. I decided to try and take a photo which showed the clean lines of the walls and detail near the ceiling. I checked the exposure using spot metering and then took several images as the exposure was not quite right. I needed to change the composition as the highlights were still too harsh but feel that I have ended up with an image that I am happy with.


Any backlit scene whether in direct or indirect light.


1/1000 f5.6 ISO 200 38mm

It was necessary to use a fast shutter speed as the wind had suddenly got up and I was being blown around all over the place. It was hard to keep my hands steady. I don’t think having a tripod here would have helped as I think that would have also been blown about. I am really happy with the composition which I had experimented with quite a bit before deciding to include the house behind which was built into the ruins. It reminded me of something from Lord of the Rings! Again I have lost some of the detail in this statue of St Edmund and remember the overall scene appearing brighter where as I feel that here St Edmund looks quite dark. If I was to shoot this image again I think that I would try again on a more overcast day so that the contrast would not be as high.


1/350 f8 ISO 200 26mm

The wind had died down again for this shot so I managed to regain some control. I was attracted to this fence around a park in the Abbey gardens particularly because of how the light fell through it and created a mirror image of itself on the ground. I think the composition could have been better here. There are a couple of very small areas of highlight clipping. I chose centre weighted metering as there are no reasonably sized areas of dark and light but looking back maybe using spot metering may have ensured that the subject was correctly exposed given that the background is much brighter. I think that I should have experimented a bit more here to see if there had been much of a difference using different metering methods.

 

1/1500 f8 ISO 200 45mm

This shot required a fast shutter speed mainly because I needed to take it quickly or risk being run over. I also wanted to let less light in as the sky became so bright behind the statue. I remember being able to see more detail at the time of shooting but I actually really like the silhouette effect here. I also shot the stature purposely so that you could not see any of the buildings behind it. If I was to re take this photo I think I would shoot at a different time of day and with a different composition. I also realise that I accidently left the camera on centre weighted metering when I should of used spot metering.
 

Scenes which include objects of very different reflectivity.


 

1/500 f5.6 ISO 200 105mm

Again I experimented with composition as I wanted the sundial to appear as reflective as possible, particularly as the top was covered in water from the rain we had the night before. At the time I remember being able to see more detail on the dial but expected to lose some of it because of the bright light being reflected. On reflection I think that I could have gone for a better exposure here but at the time I think that this image looked better on camera.


1/1000 f5.6 ISO 200 105mm

I came across this statue in the same part of the Abbey gardens as the sundial. It was presented to the people of Bury St Edmunds to honour the men of the 94th bombardment group who gave their lives in World War II. With the sun particularly bright it reflected well on the plane. I remember the scene appearing very high contrast with areas of the plane looking very bright or very dark. I think that I have managed to keep the detail of the plane well whilst still showing its reflective quality.


1/350 f8 ISO 200 70mm

Having walked through the Arc shopping centre to take all of the previous shots I remember seeing how the windows of Debenhams reflected the shops opposite. I am really pleased with how this image came out and think that it is one of my favourites from this assignment. I am happy with the exposure and composition that I selected and I am glad that I have managed to keep some of the detail from inside the shops cafe.

A scene with strong incident dappled light.

 

1/1500 f5.6 ISO 200 18mm

This was actually the first image I shot. As you enter the Abbey gardens there are many trees and instantly I was drawn to the dappled light. It took a while for me to get this shot right. It was very windy so I needed a fast shutter speed so that I did not capture camera shake. It also took me a while to get the exposure right as the whole image appeared way to dark to start off with and then looked very bright which caused quite large areas of highlight clipping. I managed to eliminate the clipped areas, capture the bright day but also show the shadows of the trees well. Overall I am happy and think that I have created an accurate representation of the scene.


1/1000 f5.6 ISO 200 45mm

I really wanted to capture part of the Abbey ruins and I am happy with the composition I have chosen. I particularly like the way the trees have created horizontal lines across the pavement. I exposed this image well using centre weighted metering which assessed the image as a whole.

 

 

 1/1000 f5.6 ISO 200 42mm

I really wanted to be able to photograph the whole shadow of a tree which turned out to be harder than expected. Ideally I would of like to photograph the tree with the shadow coming towards the camera but this was not possible due to space and the direction of the light. This scene was my only photo opportunity and it took a while to create a composition I was happy with. I also had to partly hide behind the tree as I did not want my shadow in the shot. I also wanted the building to be in the shot but there are slight areas of highlight clipping around the window frames which I could not get rid of without compromising the rest of the image. I do not think they are particularly noticeable however. If I was to retake this image I think that I would reconsider having my shadow in the scene, why not have a little bit of myself in image? I would also aim to achieve my ideal composition. Exposure wise I am happy with the choices I made.

Downloading the images.

I downloaded all of the images onto my laptop in the pictures folder and then viewed them all using Adobe Photoshop Elements 9 and Adobe Lightroom 4 which I have only just purchased and am still getting to grips with. I am still happy with my labelling system and can quite easily find any images I require.

 Pictures> Digital Photographic Practice> DPP Assignment2

 

Part Two.

Select one of the four situations that you chose in Part One and think about what the lighting conditions should be in order to reduce the contrast of the scenes that you photographed or even make them low contrast scenes. Think about the different variables over which you have certain control.

Once you have decided which conditions would result in low contrast scenes, photograph the same three images in your chosen situation in those conditions.

The Shoot.

I revisited the area two days after shooting part one. I wanted to leave a couple of days to review the images and give them a lot of thought so that I could decide how I would go about reducing the contrast in the scenes.  My plan was to arrive for the shoot much earlier in the day so that the sun would be much lower. The day in general actually turned out to be quite overcast which I also felt would work well in my favour.

I had decided to retake the images from the any backlit scene whether in direct or indirect light.


1/180 f5.6 ISO 500 25mm

Centre weighted metering has exposure the image well and has created an accurate representation of the scene at the time of shooting. I have to say that I actually prefer the original image as the shadows through the backlit fence made for a more interesting composition. There is still a very tiny bit of highlight clipping on a couple of the leaves which I could not get rid of without making the whole image more under exposed.

 

1/60 f9.5 ISO 200 52mm

I decided to keep the composition the same as I think it works well. I switched the white balance from auto to cloudy as the day was overcast, and altering the WB can make for a more accurate representation of what was seen at the time of shooting. This picture took a while to get right as initially the image came out looking rather dark. I experimented with the built in flash to see if that helped but it just made St Edmund appear unnaturally bright. I set the shutter speed slower so that it would let more light in. I am pleased with this more low contrast scene and think that I have created a nicely balance image which is a definite improvement on my first shot of St Edmund.

 

1/180 f5.6 ISO 200 90mm

White balance is back on auto for this shot as the cloudy setting gave the statue an unnatural tone. It was necessary to alter the composition as this statue is in the middle of the market square and I had unwittingly come on market day. This meant that unfortunately options for composition were limited by stalls and a rather large lorry containing meat. On camera the image looks a little lighter than it does here which is probably more accurate to how it appeared on the day. I much preferred the composition and style of the high contrast image of this statue and would of like the composition to of been the same, but with the addition of detail. I think that this shot has been exposed reasonably well but I still feel that there is room for improvement.

 

Conclusion.

I think that it was a good idea to treat this assignment as a learning process as that is what all the exercises and assignments are about. I think that I have made some improvement on my technical ability to anticipate how my camera will react before taking a shot. I have also tried to draw on the previous assignment and show my workflow through this assignment. Skills picked up during the course should also be applied to the following assignments rather than forgotten as we move on to what comes next. I think that I could have experimented a bit more with various shots but feel that I have covered the criteria well. I think that I lack confidence when dealing with exposure and sometimes panic that I do not know what I am doing. I have tried to combat this by carrying out further research and reading up on this area. I have also looked at other students work to see how they have approached this assignment and projects involving exposure. By the end of the assignment I did notice that I was much quicker and more accurate when altering the settings to create a better exposure so I feel that I have made some improvement. I also think that in some respects, this assignment shows that there is a place for high contrast images. At the start I almost felt that high contrast images were ‘wrong’ and should be avoided but as I progressed through the criteria I now understand what contrast can do for a scene. Some compositions do work well being low contrast; it is all dependant on the qualities you are looking for. I actually think that I prefer some on the high contrast shots I took, but I do understand that a lot of this is down to personal preference and style.

Reflection

I re-read the assignment criteria and have tried to assess how well I have done.
Demonstration of Technical and Visual Skills – I feel that at the start I lacked confidence in technical decisions I made but I have now made some improvement in this area. I feel that I am continuously learning new skills and try to apply them when appropriate. I think that I have good observational skills but I am obviously learning all of the time
Quality of Outcome I think that I always try to present my work neatly with well written accompanying notes. I could try to be more detailed at times when explaining why I have made certain technical decisions. I always try and relate the knowledge I have gained when relevant.
Demonstration of Creativity – I always try and be creative with my shots but I feel that I can still improve in this area and try and be more imaginative.
Context – I think that I am good at reflecting on my work and can see areas I need to improve on. I carry out my own research, visit galleries, work on my own projects and undertake further reading. I have also tried to view other students work more to see how others approach the same projects.

Exercise: Scene dynamic range.

Take five differently lit scenes, and within each, find and measure the brightest and darkest areas. Make sure that at least one scene has a very high dynamic range and that at least one scene has a low range.


 
I wanted to try and create the highest dynamic range I could to really test my camera. I also wanted to really understand dynamic range as I have had a bit of trouble with my camera. I set the camera to aperture and then using spot metering I calculated the f stops between the very darkest and brightest areas of the image. This resulted in a dynamic range of 8 stops. I also checked the histogram and this confirmed the high dynamic range. This image is not ideal as there are areas of highlight clipping from the lamps bulb and where the light reflects off the book. Zooming in there are also areas of noise. If I was to take this image again I would shoot it in a different way.
 
 
Taken at Melford Hall where I regularly photograph, this scene had a dynamic range of eight stops between the darkest area of the curtain and the brightest area through the window. This shot does have areas of highlight clipping which I would have to resolve if shooting again.
 
 
 
This image of an engine from a plane taken at Duxford was around 4 stops. I was actually expecting a higher dynamic range but thinking about it there is actually quite a lot of reflection from the floor in the darker areas. The histogram showed quite a low contrast between light and dark areas.
 
 
 
Another low contrast image here of approximately 2 stops.
 
 
I found this image quite hard to read using spot metering and I think that this is because the tones are similar throughout. It had  dynamic range of about 1 stop from the darkest area of the roller to the lightest area of grass.
 
I fully understand what the exercise was asking and how to use my camera to meter each image. I was harder than I was expecting in some ways because I am not very technologically minded.

Exercise: Your camera's dynamic range.


This is the range between the dark and the bright areas of a scene and it is measured in f-stops. The dynamic range is therefore the number of stops that the camera can capture in one photograph between the brightest highlight and the darkest shadow area. This means that it is important that the camera has a greater dynamic range than the area that you are going to photograph. If the dynamic range is less than the area being photographed then this means that some detail within the image will be lost.
To begin the exercise I first found a scene that displayed a high dynamic range. I chose to use the back of my house when it faced the sun. I focused on the patio doors so that you can see darkness and some detail within. I placed the white paper against the door to provide contrast. I made sure that the ISO setting was at its lowest of 200 and that noise reduction was off. It was then necessary to set the exposure and check that there was no highlight clipping of the white paper.
I then measured the brightness level of the white paper, the darkest area through the window and also an area of the wall in shadow. To do this I had to read my manual to make sure that I was setting the spot metering mode correctly. I always like to double check when it involves a setting that I have not regularly used before. Once set I used the zoom to measure the required areas by filling the frame with the chosen areaI then made a note of the aperture and shutter speed combinations.

I found this exercise hard to complete in several ways. Firstly it took a while for me to understand what I was being asked to do. I have also had the weather to contend with and have been waiting weeks to complete this exercise as I thought that sooner or later we would be due brighter weather. This of course has no arrived so I have decided to carry out the exercise so that I understand the principle involved and then I shall hopefully revisit it when the weather is better for a more accurate result.


 Shooting s that there was no highlight clipping requires the settings of 1/500 f6.3. I then needed to measure two or three different areas of the image. The card measured f9.5 being the brightest area where as the darket area viewed through the door measured f4.8. This gave me a a dynamic range of four f stops. I realise that there may be several factors which have contributed to this result. Firstly the lens I am using may limit the range, the weather is a factor as it did not quite meet the criteria either. From research online it wouldseem that my camera should have a dynamic range of eight f stops. I have found this the hardest exercise so far. Whilst reading the course material on what to do it all made sense and I understand the principle and what the outcome should be. It was just arriving at the point that was causing me problems. I think that I will research dynamic range further and also come back to this exercise so that I can fully understand this topic.

Beyond The Image - Topsy Turvy.

Whilst I have been preparing for assignment two, which I have found more that challenging, I took the opportunity to visit Beyond The Image. This is a gallery based in Thornham Magna, about and hours drive away. I had heard of the gallery from the internet as I am always searching for galleries which are relatively local, it is just finding the time to visit more - something that I will be trying harder to do.
Beyond The Image is run by a group of seven photographers who wanted to exhibit their own work as well as give something back to the community. The gallery is situated in a converted barn with original flint walls and is run by a purely voluntary basis by the group members.
Exhibitions are shown on a quarterly basis and I went to view the current show, Topsy Turvy. It is all about how we view things and how just by photographing one thing and rotating the image 180 degrees, it looks like something completely different.
 
 
 
 
This shot by Richard Lewis appears at first glance to show a waterside scene and its reflection. On closer inspection you then realise that the top half of the frame is actually the reflection and the bottom half is the literal scene. The composition and attention to detail are spot on. This is the only example of the work exhibited that I could find online, which I am rather disappointed about. Other pieces included what looked like tall industrial chimneys reaching up into the sky with smoke billowing around hem. They were actually in fact a close up of pillars holding up a structure in the sea with water swirling around the base of the. The original image had been turned upside down to appear as something else.
I really like the unique concepts shown at this exhibiton and it really made me think about how I view things. I has also made me more aware of really looking at things and not accepting how they first appear. We are all guilty of rushing through life barely giving things a second glance and I particularly enjoyed how this exhibition made you think and analyse each piece.

This week.

A couple of weeks have passed since my last update on my progress and I have lapsed again from my intended weekly posts. I has for some reason been harder than expected to fit everything in, but I must make more effort to schedule time in.
 
I am a member of the Royal Photographic Society so have just received their most recent journal. I am starting to read through it and aim to post on any articles that interest me.
 
This week I have also been doing work experience with my employers PR department. I work in a veterinary referral centre but we are a charity that also works to find cures for diseases in animals. This means that we have our own dedicated PR and fund raising departments. As my employer is aware that I am in the process of working towards my degree they felt that they may be able to use my services and it could be beneficial for me to find out how the promotional side of things works. I found the whole experience invaluable, as I got to see another aspect of photography and how it can be used in different ways. I have further work experience lined up with PR next month which I am really looking forward to.
 
Back in December I became aware of Cambridge Style Week and heard that they were looking for photography interns. I registered my interest as well as sending some examples of my work to them. Having not heard anything back I accepted that I probably lacked experience in the area and that it was a very popular opportunity. I have since heard back from them and am now going along on the 22nd February to photograph at their Ethnic and Sustainable Fashion Show. I can't as this is one of the areas of photography I am really interested. Luckily all the photos I take can be used for my own portfolio so I shall be posting some on the blog as soon as possible after the event.
