First, let me introduce the star of the show. Callen is a pattern by Norah Gaughan, which I've knit in Woolen Rabbit's Grace. I cannot say enough about how wonderful this yarn is for cable work:
So, I photograph in the craft room. Not ideal. Even during the day, we have minimal natural light. So I'm left with overheads, one Ott light, and yellow walls.
It works in a pinch, but I struggle with shadows and a yellow color cast, even during the day. My sollution was to invest in a high-wattage light set up, with deflectors so that the light would not be shining directly on my project, casting shadows. A white sheet serves as my backdrop.
Now, instead of shooting on ISO 6400 and getting lots of shadows, I can shoot at 800 and have to worry about being over exposed.
