I normally take my shots in RAW and normally work happily with them in Gimp on Linux. I have recently moved to a new shiny Windows laptop with Photoshop.
I have imported some shoots using Lightroom 3 but I am not seeing a faithful representation of the image either in LR nor in PS proper.
An example of the problems I am seeing can be seen in this image:
I have installed the latest Canon codecs for my camera (crc_1_8_0_68).
If I view the image on my camera's LCD screen I can zoom in and whilst there is a little noise this is nowhere near as bad as that seen in the above image.
What should I check to further diagnose this problem?
