I’m wondering about the sizes of prints offered – I have an 8Mp camera which produces a pic with pixel dimensions of 3504×2336.
at 200 DPI this gives us a print of 17.52 × 11.68″
so clearly if someone purchases a print larger than this – say 16×24 , we’re stuck with the issue that either it needs to be printed at a lower DPI (Almost there at 150DPI – 23.36×15.57″) or else the files are up-sampled through interpolation, which is never an ideal solution.
one of my works which has sold a couple of copies is only 1280×1280 so while a 10×10 will be OK, any further up-sampling is going to degrade the image. Is this a concern?
perhaps some guidelines on resolution would be good, as well the option to only sell smaller versions of files which are unavoidably smaller than ideal?
