This was a good entry, focus was perfect, as was framing, and the processing is just right I think; good saturation and contrast but not over done at all.
I find with macro if you have a hard time focusing (reading your description), using manual focus then rocking slightly and burst shooting should always get a few in focus.
I think the one thing that let you down was the angle the ant is at, it's hard to make out what exactly it is top down like this. Had the ant been side on or some other angle I think you'd have got closer to a 6 or above. |
