yes it will. 300k x 300k pixels and no upper limit on file size.
Yes it will support files larger than 2GB. However, there is a limit of 4GB on Tiff files. Much larger files can be saved using a new format called PSB.
A few words of warning though – large files take forever to save 😉
thanks for that follow up ian! 🙂
I would add, to Ian’s comments, that although TIFF has increased to 4G, PSD files are still limited to 2G.
Stephanie,
I was operating in drip feed mode 😉
However, there is a limit of 4GB on Tiff files.
Also important is if you are sending the files to other applications. Can they handle TIFFs bigger than 2GB?
If you’re using PSB, will it be supported outside of Photoshop?
harvey,
I don’t recall right off hand if other apps support TIFF exceed 2G – previous versions of Photoshop will not be able to open these files, or the new PSB files. PSB, at this point, is only supported in Photoshop CS.

Steph,
Very few, if any, other apps support greater than 2GB files. This is stated in the Help files and User Manual – not that many will bother to read either 😉
Does the file problem really exist in TIFF (I am not a big file maker, myself). I would think that large files only happen in PSD, when you are making dozens of layers and other different effects that chew up bytes.
Don,
Large files will not happen in PSD as it only supports files up to 2G and 30K pixels. If someone wants to save files in excess of these limits, they’ll need to use PSB or TIFF (or Photoshop RAW)
I got that. My point was "do TIFF files ever/often get that big". I can see it happening with PSx files, but not compressed TIFF files.
It would seem if an application doesn’t like TIFFs larger than 2GB, that would be uncompressed size. Giving them a compressed file that expands to greater than 2GB while in memory, could be just as problematic.
Yes, TIFF can get that big — partly because TIFF can include layer data.
But even flat TIFF can get that big.
Are you saying that a 2gig file can be opened but not saved or what? I have a PS file of a painting I did that ranks in a tad bit over 2gig. The original is destroyed…..and this is the only way to "get it back", so to speak.
….Hows that for melodramatic!?
Thanks,

Anton,
Are you saying that a 2gig file can be opened but not saved or what?
Photoshop CS can save TIFF files up to 4GB but files greater than 2GB cannot be opened by earlier versions of Photoshop. Likwise there may not be many (if any) third party apps that can open 2GB plus TIFF. files)
Photoshop CS can open TIFF files up to 4GB
Photoshop CS can save files much greater than 4GB using a new format called PSB. This new format is not supported by earlier versions of Photoshop nor is it currently suported by other third party apps.
Hopefully this clears up the confusion
Sweet Jesus…
I wish I will some day have the opportunity to work on a machine that can handle files that big 🙂
Just curious: what are the specs of your (yes, that means you too) computer, and what’s the biggest file size (Mb and pixel dimensions) you have worked with?
I have a two year old system with not much updating done since purchase: PC, 266MHz motherboard, 1Gb of 266MHz memory, a couple of 7200rpm harddisks totalling 120Gb and a measly 64Mb graphics card.
The biggest files have been somewhere around 500Mb psd’s (300ppi, about 4" * 4" cd-covers with a healthy amount of layers). At this point action was pretty sluggish – no real room for creativity or experimenting what with the time it took to save an’ all.
(I’m a free-lance graphic designer)
Whoops. Forgot to mention processor: 1GHz AMD Athlon (yes, could be better…)
My computer — Dual 1.8 Ghz Athlon XP, Windows XP, 3 Gig of RAM, 1.3 TeraByte of disk space. Created, played with, and saved a 250 Gig file (300k x 300k, 8 bit/channel RGB). Continued playing filled up the Terabyte of scratch space.
250 Gig file
Hmm, you beat me by a factor of 10 but then again I’m limited to 300GB of disk space – next time!!!!
If you shop carefully, hard drives are under US$1 per Gig.
Then you RAID 6 x 200 Gig drives….
Some of the recent Intel motherboards have 4-channel RAID, and upcoming dual-Opteron board specs show 6-channel RAID. I agree that RAID 6 x 200 is a practical means to working with large files. You should also consider getting an add-on RAID card so you can maintain the O/S and application separate from the 6-channel RAIDed scratch disk.
Speaking of large files, does PS CS take advantage of Windows XP allowing applications to work with 3 Gig of RAM rather than the standard 2? (A help until 64-bit OS, h/w, and PS CS-64 kicks in.) Also, it’d be nice if there was a built in way to work on a scaled down image, then apply the perfected edits to a multi-gigabyte file (with sliders to compensate for feathering, USM, blurring, etc. when applying to the larger image.)
Quale – no, Photoshop CS is still limited to 2 Gig of RAM (long story – but we need a STABLE OS to test against).
Chris, Glad to know that the 1 terabyte limit belongs to history, as those hard drives setup are becoming more and more affordable and thus will b ea reality for more people.
For the sake of curiosity, do you have a 6 disks raid 0 ???
So we must understand that there is currently no stable OS in the making supporting 2Gig+ of memory… Make one, Chris! 😉
Yes, I HAD 6 disks RAID 0. (then QE took them 🙁
(then QE took them)
Steph gives and then taketh away 😉
So Chris, does that mean there might be a PS version that runs in 64-bit mode for the 64-bit OS when available?
John – I can’t comment on un-announced versions of our software.
Gotcha…<wink><wink>…It probably is only a matter of time before it happens anyway, especially if 64-bit takes off…I will keep my eye’s open for a 64-bit version…Thanks anyway Chris
John,
Your question is posed in such a way that Chris could have answered ‘Yes’ without commiting himself/Adobe in any way – Of course there MIGHT be such support in some future version…<smile>
