Using K10D with Sigma 17-70 in P Mode. I'm finding that most of the shots of the snow seem to underexpose. Here's 2 representative examples of in camera JPEG followed by same photo after auto PP in Picasa2. Am I doing something wrong?

Try changing the metering mode.

no you are not. the meter in our cams is stupid. what it tries to do is give you an EV that balances out to 18% gray. that's why your snow is gray instead of white.

Thanks Roy. Anything that can be done about it? I find I have to PP pretty much every photo and I think Picasa2 overdoes it on the contrast.

Have never got round to somthing more powerful. Don't really have time.

Use the Exposure compensation, it's there to help you out in situations like these. But you'll have to practise to get the feeling for when to use it, and how much you need to compensate in a given situation. You can use the histogram info in the camera, if you shoot pictures like these with a lot of snow there should be a large portion to the far right in the diagram, but still within it.

just as kjell said. try setting the EV to +2 and see if that doesn't do it. if not, take a look at what the meter says and go to manual and raise the values there.

Thanks Kjell, Roy. I do sometimes play with exposure comp but for these it was too bright to be able to see the photos on the slopes. Only looked at them when I came home. Out of interest how do you interpret/use the histogram? Something I've never worked out? Also, if shooting in raw is it possible to change exposure in pp? Haven't been able to use Raw recently. Unfortunately I thought K10D would work with PPL3 that came with K100D. Unfortunately it doesn't and I've no idea where my K10D software is.....
