Dear All

I am trying to catch up with some of the PDML postings regarding
'correct' exposure of RAW format pictures etc and have come across the
following links, no doubt very familiar to most folk here but I hope it
doesn't hurt to repeat them:

One of the benefits of cameras like the Sony R1 with its EVF was that
you could learn to see the correct exposure as it changed in the
viewfinder. Not so with a K20D Pentax! In a way, I am glad, as it is
making me learn to 'see properly' again ... I hope.

One question though: exposing to the right will invariably mean slower
shutter speeds. Good that the K20D has shake reduction then but it
occurs to me to ask what is the best ISO setting for minimum noise?

I gather that digital SLR sensors have a 'base' setting, i.e. its true
sensitivity. Does anyone know what it is for the K20D? Answers to the
same question on dpreview are not conclusive and vary equally between
100 and 200.

So, in an ideal world, where I am placing my camera on a tripod for that
glorious landscape shot, what is the best ISO setting for image quality
- 100 or 200?

Thanks
Lee

P.S. What on earth does 'PESO' stand for? Is there an FAQ for this list?
