Here are some resources to help you take professional looking photos of your prototype figures. Click on the images below for a link to Amazon.
First is the Tracer. This is excellent for taking photos of carded figures with Freeze Frames and/or any type of transparencies. Second is a photo tent that allows a good clean backdrop for 3D items. Last is using the PhotoRoom app on your smartphone. This allows for quick cropping of your items. You can replace the background with colors, add shadows and more.
