WAM stands for Wet & Messy. You learn things in a photo studio.
One day, I received a telephone call from a woman who wanted a photo shoot that same afternoon. She had turned 50 and wanted to celebrate her birthday with some photography.
She brought a very nice bottle of whiskey and I asked her how she wanted to be portrayed. Furthermore, she told me she had a thing with yogurt.
It was quite an intense session, but I discovered a whole new range of photographic possibilities.
I also learned that it is a good strategy to warm up the yogurt to room temperature, before you the fluid on the model.
