Very nice stil life, no complaints technically, estically, I think this is a bit (just a bit) stark (a.k.a. bare). Concentrates your view, yes, but hardly excites. Photo 10 Creativity 6 B&W 9 total 8 (some may disagree, but I like the off center look, too)
Hey. Nice. That's truly black and white. My only suggestion is slightly more depth of field to include the bottom and back of the pepper in the field of focus. Really excellent tones, with detail in all but the darkest shadows.
Now this is a shot that I would like to have taken. Usually done (and done well) in color, it is very intriguing in b&w. Well executed! :) I would probably have cropped just a tad more off the top (outside of this challenge of course) to emphasize the ROT.
The cool thing about capsicums (it's what we call them in my country :P) is their vibrant colour! It's interesting that you chose to photograph it in black and white. The shape and texture of it isn't very compelling to me, which are things that black and white will emphasis by de-emphasising colour. Interesting idea though.
This is WELL done. The crop is perfect and does adds to the rule of thirds. The light on top is JUST enough. It looks like a photo that would be sold for a kitchen wall. GREAT job !
