My photos are not as nice as most of the amazing cakers I see around but I am broke and usually VERY tiered when i finish a cake and start taking pictures of it lol. I use poster boards for my backgrounds (2 for $1 at dollar tree), my Iphone for my camera, and a lamp with no shade as my light source. I just set up my poster boards, place my cake then hold the lamp where I need it with one hand and take photos with the other. Quick, simple, and pretty decent results with minimal cost and effort.
