I've been asked to give a lecture/demonstration with handouts to a 25 person group of skilled amateur painters on how they can photograph their work for various purposes up to, but probably not including "fine art prints" of their work. I know what they "should" be doing and have shared the write-up with a couple of them in advance. They've asked that I include recommendations about what specific cameras and software should they get. I've stated no cell phones or tablets,. I'm suggesting using a dslr and RAW, and I'm recommending Lightroom. I want them to be able to white balance against a gray card, crop, rotate and adjust contrast and saturation. However, I recognize that a lot of them won't want to spend that much $. What specific less expensive cameras (point and shoots??) and software would you suggest I include as possibles?
