First impression: This is a good shot. Your choice of BW (sepia) is excellent. Meets the challenge with no problems.
The photo has an amazing depth to it, even (and especially) at the top, where the glass melts into the background. The glass looks so rounded and smooth. On my screen it is hard to distinguish that the glass is a bit over half full with liquid (wine?) and I find the two little "hooks" sticking out on either side somewhat disconcerting. The pattern created by the liquid is quite beautiful. I'm wondering if the picture would be more effective if it were just a little lighter.
Focus is very good.
I like the slanted horizon line, it works well in this photo.
Lighting is excellent. This was a hard subject to light properly, and you did it very well. Again, I'm wondering if just a bit lighter overall would improve it (something to try).
Overall, this is a very good shot, good to look at. Keep up the good work!
Fantastic use of lighting. where was the light source and what was it? Also what did you use as a backdrop. I really wanted a moody shot like this but ended up discarding over 20 B&W of a galss against a bblack card backdrop as the reflections were always to complicated to deal with. WEll done.
Very cool image. I like the background you chose and how it makes the image stand out. The blackness of the background at the top of the image, also makes the glass shiny and stand out more.
What a great shot! Really like how the outline of the glass and water seem to meld into a swirl-like pattern. The composition and cropping are excellent as well. The only thing I could think of to improve this shot would be to tone down the lighting on the lower left side, although I don't know if that would be possible without losing the effect of the rest of the shot. Very high score - good luck in the challenge! :)
There are some interesting shapes and shades here, but there's something lacking. Perhaps a little more light at the top and less at the bottom of the glass - or swap the ligh/dark background pieces over.
