A painting is very different from a photograph. I’ve read artists complaining that the images of their work don’t impact in the same way as the original painting. Nature of the medium. A photograph is a different view of the work.
I take promotional and documentary photographs on film of pieces as I complete them. Film give a resolution that when scanned allows prints at actual size without stretching the image capture. The roll holds ten shots. Two paintings only use 6 to eight of those. I usually try and take In Progress shots of some of the other works as possible.
Sometimes this changes how I see the work – the urban/abandoned moscow #3 below – that is much closer to done than I had realized.
And Venice (Sunset #8) – a photograph of that shows me what I have, and several areas that don’t work as yet. But in some ways better than I had in mind.
Some artists seem to think that only the final product should ever be seen and HOW should remain a complete mystery – I think the decisions are more mysterious – ANY of the decision points could go any direction – different color, different texture, different feel for it – and those are the mysteries.
