That they are! Lighting's a little bright, they seem to be glowing. Unless that's the effect you wanted. Composition works, though there must be more interesting arrangements out there somewhere. Maybe a curve of some sort?
Why yes, yes they are. 2 things bugging me about this shot right away. first, the strong horizontal line in the background is not straight. my big pet peeve. it's very close, but seems to round near the right edge of the photo. blame it on my OCD. lol. second, is the reflections on the grapes of the lighting. It's really bright and stands out on the second grape from the back. that one is a distraction. Also, the 3rd grape from the back is crooket compared to the rest. In a photo where the main impact is the line up, I think it's really important to get the line up straight. I think this is a fun shot, and there are definately 7 of your subject. I also like the DOF. ~Heather~
For a photo like this, I would set aperture low so that you can get a larger depth of field so that all of your grapes would be in focus. I am not a stickler about every detail being in focus, but it would lend itself well to this photo, however. The shadows and reflections below the grapes are a nice touch.
nice composition. grapes might look a little more natural with less JPEG compression. Your file can be up to 150KB, this is just over 15! I'm not particularly fond of the shallow DOF in this image.
