I put the "u" in Humour because I am British, but you can spell it how you like!
So I have basically gone for just a hint of red in my high key photo. Doing this actually makes those parts pop! This photo was taken using a tripod and lots of light. The manual settings on my camera were f/8 ISO 100 and exposure 1/13. I took a spot reading and then upped the exposure +1 and checked that the white balance was correct This is Kelvin 6400.
High key photography needs a bit of post processing too, I then did up the exposure and whites even more in Lightroom.
Using your mini figures helps with making a fun image.
