I got some comments before I could write about this photo - thanks!!
This was a killer to process. They were both moving and the kitchen cabinetry is dead ugly. I decided to go with BW, and fiddled with various conversion methods, levels, different contrasts, hard light, softer light, etc. Consequently, I don't really remember all my steps, because I worked on it a long time.
In my opinion, this candid is a jewel. Pure photographer's luck, let me tell you.
What a great image. For me, there's a lot of story here, slightly menacing, and it also has a fifties or sixties feeling, enhanced by the houndstooth, despite the modern kitchen. A great image.
