Before I start listing expensive photography equipment, I should mention that I have dedicated cameras and lenses for other photography. You can probably get similar results using a decent phone camera, but I haven’t done enough product photography with a phone camera to be able to give advice there. Some of the info here will be helpful with a phone camera, some will be more useful with a SLR-style camera.
I’ve been asked many times about how to take good photographs 3D prints, and it’s always hard to answer in a brief format. Just like giving advice with 3D printing, it’s hard to know what will be useful without knowing more about the hardware, software, experience, and intentions. Even in a longer format, photography is just too large of a subject to cover without skipping over a lot of important details. I actually started this post years ago, but every time I try to finish it, it just keeps growing. So I’m going to split it into sections, starting with the basics, and I hope to get to the rest someday.
