What does she think? Will the owner continue playing or is he to feed or to open the terrace door? He apparently has something related to me in his mind but what is happening now? Ah, a picture again.
What does she see? This is my interpretation based on some pages discussing cat colour vision, like Kitty Show. The soft, rather even light on her was achieved by reflecting the flash light behind the camera, towards the corner of the almost white walls and the ceiling.
Shallow depth of field on the cat picture is achieved by aperture f/2.0. (Nikkor 50mm/1.8)
