painting ranking - the story continues

Growing success with pinhole photography as skills in exposure time / aiming of camera and composition continue to improve. Inhibeited by the poor weather conditions most shots are indoors but I feel I have taken advantage of the pinhole camera's very large depth of focus which keeps everything in focus. This is in sharp contrast to a std high sepped exposure normal camera view where only the foreground or the background are in sharp focus....but not both. In many ways this is how our brains work in that it focusses on what is important at the time but does not process all of the information sent from the eyes.

It could be argued that pinhole or at least very small aperture (large depth of field) is a way of looking at our surropundings in a new more comprehensive way than is the norm.


Wooden Box camera - outdoors - 10 mins exposure.
As is often the case the negative raw image is more interesting than the resultant positive from post processing via photoshop. One can create positives by exposing a new sheet of paper thru the inverted negative paper image , but this is not very advantageous and I personally think negative is 'generally' more interesting causing you to stop and stare automatically to try and work out what is what. As well as being negative in terms of black and white the left to right swap can be confusing but in these examples remains uncorrected, largely thru laziness and reluctance to go for true repreesntation.



This is one of the initial successes. Strong light thru skylight dominates overhead but the clock and flasks on the wall are resolved reasonably clearly. This was taken as the initial subject on a cold windy day to evaluate the possible distortions of images via the photo paper bending...accepting the data from the pinhole.


This distortion , curvature of normal rectilinear 'flat' definition was acheived using convex paper bending with paper bent closest to the pinhole in the centre.

The convers 'concave' bending results in the following equivalent.


Again , in my opinion the 'negatives' from a more interesting view than the positives shown below.

NOTE - There is 'hairiness' of the edges of the image. This turned out to be the feathering of the carboard in the hole formed to take the pinhole formed in the small sheet of flattened tin. (piece cut from empty coke can).
This issue was resolved in later images by trimming back the edge of the cardboard further from teh active pinhole. (surprisingly long way ...but the pinhole does have a very wide angle view of the world).
