Pretty good Jesus...
This goes for ANY equipment you claim for your photography work...(i.e. your computer, laptop, etc.)
If it is NOT used for your photography business only, then you cannot write the entire amount off! This is exactly why I say consult a CPA. Cause if you ever are audited, they will hit you with this...if you don't have "seperate" equipment, they try to get you on this.
Best way is to consult someone that knows all the current issues and can do your income/loss and taxes for you.
