There are many occasions where we as photographers focus on a subject and make it the center of attention, but when you take a abstract photo the actual subject may not be clear to the viewer at first. That can be a good thing, because it will make some viewers stop and think about your image, letting them use their imagination. On the other hand that could be a bad thing, as some people will simply look and be dumbfounded before they quickly move onto something else. Today's photo is just such a situation, because without knowledge of what the subject is, it would be difficult to determine what it is.
I like this shot due to the way the line moving through the left of the center of the frame leads all the way through the image. The photo is of melting ice that was on the marsh where I was photographing last Saturday, just in case you have been unable to figure out what you're looking at.
