I love these photos! I've found I really like a shallow depth of field when photographing my geckos as well, I think it shows them off nicely. Your geckos are gorgeous and the photos really show them off well!
Thanks a lot for your comments, I'm glad to see you like the pictures !
Photographers usually tell me I should use a wider depth of field, but I totally agree with you about that. I do not have choice anyway, shutter speed is about 1/80 so I already have to stop breathing to take these pics ! Not so easy actually haha.
I prefer a shorter depth of field too. I always like seeing the contrast of a subjects sharp detail and the soft bokeh that is produced by the broken points of light from the unfocused background. It makes common subjects into works of art when used correctly.
