I have recently upgraded to Adobe Lightroom 2.2 as my primary software for keeping track of and doing quick adjustments to my pictures.  Recently I shot a studio session where I used 14 bit RAW files with maximum quality saved with lossless compression by the camera. The files comes out on the north side of 15 MB each which is a lot but I have equipped my computer with 4 GB of RAM and it should not be a problem to handle it.

But it is, particularly when doing the following things:

• Exporting a large number of large pictures.
• Working with the adjustment brush extensively.

There are other people who have experienced similar problems I am considering downgrading to 2.1 until they have fixed this problem. I just hope the library files are compatible back to 2.1… don’t want to lose all the adjustments and settings.

There are discussions about this on the Lightroom forum.
