I am going to be doing some product photography but I am running into an issue. This issue is achieving the proper lighting. My ideal setup would be a light tent with a few lights and my issues would go away. However, I am in a situation where I do not have the luxury of setting up a light tent nor using extra lights. I have considered using a speedlight with a diffuser attached to help add more light to the photos.
I will be shooting products from books to glass artwork. Is there any advice on what I should try to get the best possible photos of these products if I cannot setup a light tent or access additional lights?
Note: I am using a Nikon D5100.
