> I think being a stubborn git I would probably have proceeded to find my own tufts of black hair and continue shooting it until I got it right since it became a real challenge. I feel this. I am a web developer but I'm sort of at semi-pro level as a photographer (albeit not a generalist.) I once had a web development job where I did some of the photography and so did the graphic designer. The product was literally a set of different grades of white marble powder. Not only is it nearly impossible to differentiate these, it's also probably pointless, because the differentiation is more in the material properties than the visual properties. Nobody cares for the photos and yet they were fairly complex to get right. We did eventually settle on "use in practice" photos for the products but even then, the uses are overlapping, not wholly distinct. Quite a challenging job.
