Ok this may sound a little ridiculus to you but stay with me. I need to open a 600MB TIFF in Photoshop. I can't break up the image. I just need to know if it can be done and what system it needs. Right now its on a Powermac G4 Dual 1.25 w/786 RAM. Thanks a lot.

BTW, what kind of file is this that's so large?

That should work, albeit maybe a bit slow. You *will* end up paging some memory to disk because Photoshop tends to like to have twice as much memory available as the file size, but it should still work. Just be patient with it.

Nothing but the highest quality porn for him
...my way of saying I'm curious too

We work with files that are 800MB-1.5GB. High resolution, a dozen layers with layer effects, etc. can really bloat the file sizes up.
Oh, I can imagine a Photoshop file that large. This is a TIFF, though.
So either he's opening something REALLY large, physically, OR it's something fairly normal-sized (8x10 or so) but at a really high resolution (1200ppi or more?).
Hell, to reach a 600MB file, I had to plug in some ridiculously high numbers in the dimensions or resolution fields!
Must be a bus stop poster or one of those banners you see airplanes tow.
Although those aren't usually high-res...we always did large format stuff at 88-100ppi off our big 5' Encad and if you viewed it from 3'-4' feet away (or farther) it looked wonderful.
IIRC, LivePicture was good at monstrous files due to fractal compression technology

Problem is Photoshop will only recognize up to 2GB

However, Photoshop CS now supports images up to 300,000 by 300,000 pixels, 10 times the pixel count of version 7.

(Under "For Graphic Designers" on page 1)
So it looks like if you upgrade to Photoshop CS you will be able to open the file.
Also (this is mainly for Brad), Tiff files can now have layers just like psd files (new to PS7). The thing is that if you take a layered image and save it as both a tiff and a psd, the tiff will always be larger, in many cases much larger (without compression). Typically I only save flattened tiffs. InDesign can handle psd files, so layered tiffs really arent all that necessary... but it looks like in this case, he really does just have a HUGE file
So upgrading to CS should solve the problem
Hope this info helps.

PS tend to use more in the order of 3X to 10x the file size in RAM these days. It, of course depends on history states, layers, and live type and adjustment layers. A better rule of thumb with v6 and up is 10x--I'm never surprised this way.
