You've had a lovely day out with the camera, all your pictures look great on it's little screen and you go home happy.
When you download them onto the PC, you find that in several of the pictures you thought would be the best, the subject is out of focus and all the background is in focus.
How frustrating is that?
It's a common problem when using auto focus, but birds are far to quick for manual focus I find, so I have to take my chances.
Very Occasionally, I will try and tweak the picture to sharpen it up, but I really don't like to do that. For me it's all about capturing the right shot, not taking a picture and manipulating it to look good.
