I have a problem with high ISO in Lightroom2

i83N · 04-22-2009, 03:47 PM

I have a problem with high ISO in Lightroom2. When I import RAW images from my Pentax K20D with a high ISO (800 and higher) setting some of them are totally ruined.
Does anybody know how to get rid of this problem?

Ruined how? Can you post a screenshot or export one of the resulting images?

i83N · 04-22-2009, 03:55 PM

Yes, I forgot to post shot

Looks like either your camera is defective or your memory card is - unless perhaps other RAW processing programs can process the file just fine? Don't be fooledif they *display* the picture OK - all that means is that they can read the preview in the file. Check to see if you can actually adjust expoure, wb, etc, using another program like the one that came with your camera.

Yeah, that's not likely a Lightroom problem. Try with a different memory card first.

It happens when a shot already in LR library. At first thumbnail preview is normal, but when I open a bigger view this thing happens.
I tried with a different memory card same thing. Happens not to all shots only ISO 1600 D-range

Could be a camera problem - you still need to test this using a different program to process the same file. And again, not just look a the preview, but actually try to process it.
