PS. I remember, the hammock was swinging and that's why it's not sharp. I was more worried about the low indoor light, I should have been thinking about the subject movement.
Yeah, I think I used the 50mm Pentax f/1.4 so DoF was very thin, although the lens is sharp. Subject was not fully parallel to the camera plane. Also I had to use print film, transparency would have sharper results... I am going digital. In Guyana it's not easy to get photos developed.
I like the overall luminous impression, but maybe I overexposed by 1/3 stop?
