Shooting Ski Goggles
These are hands down one of the most difficult things I have ever shot! They are basically curved mirrors that reflect EVERYTHING! They somehow manage to see the edge of the diffusion even when you think the goggles are completely surrounded by it.
I've finally developed a rig that is quick to put together and minimises retouching so I can get through these quite fast now and in a very repeatable way, so the goggles I shoot are all in a consistent light and angle even when photographed months apart which I feel is essential for a good looking e-commerce website.
