Sometimes the simplest photos can be the most difficult to critique, because there is so little going on. Many of you found the major issue I have with this photo (although it is easily remedied). Here’s my critique, so you can see whether you saw the same thing I did:
The miniscule depth of field of this photo is every bit as important as the subject matter. The eye-catching, vibrant orange and texture of the mushroom gills draw the eye in and make the eyes focus and scrutinize them. The out of focus mushrooms at the bottom left and top right also add a lot to the photo, as the soft blotches of color add a certain dreaminess to the image. At the same time, the greens break up the image just enough so that it isn’t all orange and brown-black. Focus is very good, although perhaps a slightly different orientation might have brought more mushrooms into focus, and sharpness is spot on. Exposure seems good, as there are no obvious blown out areas, and most of the dark areas still have recognizable features.
The biggest negative is the negative space in the top left corner that is derived from the fact that the line of mushroom heads falls below the 1/3 line of the image (as espoused by the Rule of Thirds). Cropping the image slightly from the top would eliminate some of that negative space and bring the line of mushrooms to the 1/3 level or slightly above. Cropping slightly from the bottom would also eliminate the slightly distracting light object at the bottom left of the image and some of the somewhat negative space at the bottom right.
Did all that make sense?
