In a previous post, I explained a quick way you can get sharper photos by adjusting the “picture style” on your DSLR (if you’re shooting in JPEG). Well, another small way you can make your closeup photos appear sharper is by photographing your subject in front of a contrasting background.
The photo above is a good example. The dragonfly is pretty bright, but the background is much darker. This strong contrast of brightness helps emphasize the edges, making the outline of the dragonfly appear much sharper.
This is actually how most sharpening algorithms work in post-processing software: by increasing the contrast of brightness between edges it makes those edges stand out more and appear sharper. That’s why oversharpened images have those ugly halos. [Read more…] about Quick Tip for Getting Sharper Closeup Photos
