Watering canby
booboo_goonComment: Greetings from the Critique Club.
You used an original idea and you picked a very difficult set of objects to photograph. Let me explore some ways in which you could have improved this.
Composition. I think that the faucet needs a bit more headroom - the crop may be a bit tight at the top. I think I would have used the rule of thirds here and put either the faucet or the can on the thirds yet composed the image such that the whole image is not centered.
Stainless steel and water are very hard to photograph. This image would require the use of levels and curves and some selections to make the faucet jump away from its background. You are basically using tones, and not colors, to make all your distinctions. That is difficult. It appears that your highlights may be blown out - top of faucet and edge of sink. Close attention to your histogram while shooting and while editing is critical to controlling this.
Likewise there are too many parts of this photo where you have lost detail in the darks. In post processing there are number of tools that can help you here. If you shoot in RAW and have PS CS2 or CS3, the tools in ACR can do wonders. Shadow/highlite help immensely. And to a lesser degree levels and curves. If you really want to control the extreme ends of the spectrum you can try HDR.
But assuming you do not have those tools available to you, you did a good job with a difficult subject.
(I finally learned to stay away from reflective surfaces for challenges because the highlights are so hard to control.)
