Really like the photo. I just need a little explanation why with a speed light have a iso of 1000 and a shutter speed of 1/60? I would have expected a higher f stop and shutter speed at that iso. It obviously works for you well.
I was actually experimenting to see how much noise would be noticed on the D750. I didn't expect it to look that well at iso1000. The f3.5 was for the shallow depth of field.
A very beautiful portrait of a very cute doggie. If you click download, and click on the photo, you can see the umbrella in the reflected light. The detail of the fur is wonderful.
