Assignment 2 reshoot, thoughts on depth clues, experimenting with long exposure

Got the films back of the 5x4 shots I took last weekend. My 'lucky guess' approach to near-darkness photography didn't quite work out, so went back and re-shot in a more scientific way. Also re-shot the images I lost to a computer virus last week, and did some further experimental work.

Finally making feel I am making proper headway with Assignment 2, and have produced some images I am reasonably happy with. What I have learned so far with regard to 'Eliminating Depth Clues' is as follows.

• The longer the telephoto lens, the greater the compression on depth planes, which helps eliminate a sense of distance between them. 
• Eliminating the 'ground' or surfaces between objects further reduces the clues to the distances between things.
• Large depth of field (from small apertures) can help also by not separating objects through the softness associated with narrower depth of field
• Atmospherics play a large part; haziness and its muting of colours gives clues to depth and separation, clear air helps reduce these clues.
• Areas of similar or uniform colour / tone in clear atmosphere give less idea about depth than contrasting colours / tones.
• Looking down towards ground sloping up and away (eg at the other side of a valley) flattens perspective due to it being nearer to a plane parallel to the film plane.

The further experimental work mentioned earlier is connected to finding the optimum balance between ambient daylight at dusk and artificial light from streetlights, floodlights etc. I did quite a bit of this last year during the 'Twilight' series of images, which were shot in the urban environment, but the project I am working on involves lighting further away, so may be a little different.

One thing that can definitely be said is that this is much easier to shoot on digital than film, as the results can be reviewed immediately. As I am getting more and more interested in the use of  medium and large format cameras, I will need to transfer the knowledge and adapt it for use with film. This involves factoring in reciprocity failure into the equation, and also tackling the idea of diminishing returns during very long exposures as dusk turns in to night, and the amount of ambient light falling off during the actual exposure. I predict a lot experimentation is going to be needed to perfect a technique. I will look to two of my favourite photographers, Todd Hido and Bill Jackson, for inspiration.

Tonight I will be reading more on Stephen Shore for my critical review, and making some notes on points I want to make in the review.
