im no photo expert (worst subject in college) but i use a Photo Studio-in-a-Box. They are cheap like $70 and folds up to store away till ya want to use it.
I use a Panasonic Lumix 10.1-Megapixel Digital Camera . I just try to take my pictures using sunlight into my room on weekends. I can never get good lighting during the night with how dark my apartment is. I use manual settings on my camera to get decent pictures. I am sure that cheap light box i use isnt the best thing out there and i would create my own using online guides. But i just dont have the room to do so.
I like natural sunlight to take all my pics, which is why during the day seems to give me better pictures with my set up.
