Thank you everybody! So kind of you! Of course, my model didn't need the additional ego stroking...
thebeatles, the lens is the Tokina 35 mm M35 Pro f/2.8. It's a macro lens, and I was very close here wide open. Yes, the only light is what was coming from the window.
Almost no processing, except trying to get rid of a booger next to her eye After taking this I tried to clean it off so she hissed, bit me and ran off (a common sequence of events...) so this was all I could shoot...
