Memory management problems

I’m trying to remove chromatic aberration (blue fringing) from a large scanned image 600MB file (300 MB layer) but I keep getting the error message:
The operation could not be completed.
Not enough storage available to complete this operation.

I currently have the maximum of 2GB of RAM on my system with 1.68 MB available to Photoshop. My Cache Level is 6. I have plenty of scratch disk space for the program to use.

The function does start to work after I SAVE the file, maybe because it frees up scratch disk space. But, it eventually bombs.

I’ve also tried creating a file with just that layer and then applying the filter. No other files are open. But, this bombs, too.

I then tried closing Photoshop and then reopening it to clear out any memory that may have been tied up. It finally worked.

When I print, I also get an error message about not having enough memory. I save files and that works most of the time even though I DO NOT CLOSE THEM. If this doesn’t work, I do close whatever I don’t need. If it still doesn’t work, then I close and reopen the program. The prints I’ve been making are only 8×10’s, though, admittedly, the files can be up to 2GB large.

Anyway, I think PS can’t completely handle the memory.

Any suggestions?

Thanks!

Try to decrease memory assignment for PS to 55-60%. Just for experiment.

Filters, plug-ins, printer drivers, print spooling, the Bridge (in CS2), and any other program running at the same time are competing for what memory is left after you have given Photoshop it’s allocation.

Mine is a 2GB machine and it works best with the default 55% allocated to Photoshop.

I have plenty of scratch disk space for the program to use.

How much is plenty. If your files are up to 2GB (!) you’ll need at least 10GB of defragmented scratch space (I have 20GB)

Also, make sure there are no redundant .TMP file lurking there from past crashes.

The message that you list, is not a Photoshop message – that sounds like an OS message (meaning that the OS swapfile volume may be low on space).

So, allocating LESS space might be better? Wouldn’t that just slow things down to a crawl? But, I’ll try it if you think it might help.

Also, how do you actually allocate space? I simply tell it what drive to use and call it a day. Is there a more precise way?

I think you are confusing Memory Allocation with Scratch Disk Assignment.

In EDIT>PREFERENCES>MEMORY & IMAGE CACHE you tell Photoshop how much memory (RAM) to use. The default is 55%. Setting a value higher than this can starve the OS, Bridge, other programs, and your Plug-ins and Filters, of system resources.

In EDIT>PREFERENCES>PLUG-INS & SCRATCH DISKS you tell which drive the program should use for its scratch disk. This drive – preferably a different physical drive to the one used by the Windows Virtual Memory – should have plently of defragmented free space.

Photoshop Memory usage:

Edit>Preferences >Memory and Image Cache – Set the percentage used by Photoshop to 55%

Windows Pagefile:

Right-Click on My Computer Select Properties>Advanced>Perfomance Options>Virtual Memory>Change.

Set Min=Max=2x installed RAM (In your case set to 4 gigs)

Thanks for all the help.

I just changed my Percentage used by PS to 55% and my OS Virtual Memory to the maximum of 4095MB on the "C" Drive.

A couple more things:

1) If I keep my image files on what I call the "I" Drive, then should the scratch disk be on another drive altogether for peak performance? I set it to my "D" Drive as to not conflict with the OS Virtual Memory on "C" and the images that are stored on "I."

2) When I perform an "analyze" in the Defrag program, it says that my two smaller drives do not need Defragging, and it seems like there’s enough free space. So that’s good. But, on the very large "I" Drive where there is 139MB of free space, the thing tells me that it Defragging is recommended. Of course, I’ll defrag this drive, but if there’s a ton of CONTIGUOUS free space, this is the most important thing as far as Virtual Memory goes, right?

Oops, one error, there’s 139 Gigabytes of free space on the I Drive, not MB.
