1. A copy stand makes photographing peices of paper massively straightforward. One can ensure that the paper is square to the lens.
2. I cannot work out the proper white balance settings. They don’t seem to correspond to the literal lighting arrangements. Auto white balance produced usable and mostly good colour images.
3. Focussing on a surface that looks kind of random seems to make it difficult for the focussing algorithm of the auto focus.
Q: How extensively can one edit a photo file before the aesthetic processing has produced a new work rather than a more accurate photograph of the physical work?
