Why, WHY can't people a) buy a decent camera b) learn to take decent photos with it and c) wait till the sun is out and find somewhere that isn't covered in corrugated iron as a backdrop.
Or failing that d) hire someone to take photos for them?
Surely any of these would be preferable to getting me to fiddle with their bad photos afterwards. I can get them looking vaguely half-way decent, with some effort - but would it not be simpler (and cheaper) and much more effective to just supply decent photos to start with???
