People obsessed with image sharpness sometimes can do themselves a favour by thinking outside the box for a while.
There might even be money in it ....
This image was really an accident, as I automatically pushed the shutter release when I stepped out of my car and didn't realise immediately the snow covered mirrorlike ice underneath. You fall hard in those cases, but I had heard the camera went off so checked the display to see the image taken. Well, a pattern of sorts had been captured, so didn't delete the file.
Submitted it to my stock agency and a couple of days later it had sold for $1000.
I'm sure there is a lesson of morale hidden here?
