I've been taking pictures of shoes inside the box shown in the picture, and the lighting is on the ceiling on the inside of the box. I'm also attaching a picture so you can see which shadows I want to eliminate, as doing it in Photoshop is not efficient time-wise, and not perfectly accurate. Keep in mind, that the box's sides can be unfolded.
The shadows are the ones on the outsole and in front of the heel.
I tried using two lamps that I have (Professional Quartz Light QL-500) but then I had shadows on the side and still didn't eliminate that particular one. I really don't know a lot about lighting, so maybe you guys could offer me light positioning advice and if I might be needing another lamp like those big umbrella-like ones?
Please forgive my lack of photographic lingo knowledge, I'm really new to photography!
Thank you in advance.
