Working with big files

#1

Im currently working on a large print with a size of 17717x10625 pixels. My problem is that it seems to me that Photoshop (have tried CS3 and CS4) does not like these sizes. When i try to use different filters I get error messages saying im out of RAM or disc space. The ram bit I do understand if the program wants to put the whole file into the ram, but that’s just plain stupid. On the other hand, I can’t imagine my file to use 300gb of disc space, or am I wrong?

Is there any workarounds for these problems? Or any other programs that will work better with large files?

Well, how much RAM do you have? And how much disk space have you allocated for Photoshop to use as virtual memory?

#3

I have 3,5gb of ram and both partitions on the hdd have been enabled for PS to use, thats a good 300gb of free space.

And how much of your RAM have you allocated for PS use? I don’t personally know of any applications which may handle large images better, unfortunately. But surely there must be a way to optimise your file so as to avoid these headaches.

I have tried to set PS to use 100% with no luck, I then tried to opposite, give it 40% so that it would not cause the whole system to run out of memory, but insted use the scrath disc for this.

i’m getting the RAM error sometimes even with small files. i have 3.5 (4Gb) too. it might be an allocating problem

as for the scratch disk(s), i never use the same physical disk as my system. i know that can create some troubles

What filters are you using? Are they plugins? There are soooo many reasons for this error to pop up but sometimes it comes from a plugin not being installed correctly (weird as that sounds… its true).

What about the efficiency meter in your current window open? What percentage does that read?

Also, don’t set your ram allocation to 40% or a 100%. Its kind of an extreme at both sides when dealing with large files. You’ve got to have system memory for everything to work properly and you also can’t have to little if your dealing with large files. Best is to set it to default and then bump it up slightly in several increments…

I know your saying that its a large print at x size but how large is the file exactly?
