| Just saw the post on glasses and camera, I'm OK there. But getting old, been wearing reading glasses for about 6mos. It seems to me that the glasses lightens the shot more & when I take them off the shot is a lot darker. Any one else have problems with reading glasses ?? |

Nope, just I can't read the forums without them. Trouble is one pair of reading glasses isn't enough. I have one pair for computer, another for reading and another pair for really close up stuff, like using screwdrivers, computer building etc.
I also have a pair for driving etc. Damned easy to muddle them up and find myself groping round. |

Ace, the less in focus an image is the darker it appears. Focus = contrast, basically, and the more contrast you add the brighter things appear. To see what I mean, just open any normal image then start applying gaussian blur to it and watch it appear to get darker, then apply extreme USM to it and watch it appear to get lighter.
So that's what's happening to you. Most likely, the way it appears with glasses on is the more accurate perception of its lightness.

Thanks Bear, that makes sense. In the pet challenge is the first time I took my glasses off for exposure, several comments state its to dark in the shadows......Thanks again.
