Hi, I am an amateur photographer. I display my work in local galleries and have sold a few photographs, for which I have to pay taxes, of course. I am filling out the necessary forms myself, and one of them is Form 4562 for deprecation of equipment. I used my new printer and camera more than 50% for business last year. My first question is concerning written evidence for >50% business use. Do my image files constitute written evidence (there are very few pictures of family, friends, etc. there; almost all are like the photographs I sell)? My second question is whether to use GDS (general) or ADS (alternative) depreciation system. I would appreciate comments by anyone with similar experience.
