Hi folks,

From this PDF FAQ we have:
  • Photoshop for Microsoft® Windows® will run 64-bit-native with the next version release.
  • We’ll need additional time to complete our Macintosh® 64-bit version, which is now planned for a future release.
  • In early testing of 64-bit support in Photoshop for Windows we have observed overall performance gains in the range of 8-12%.
  • 64-bit support will only be available in future full-version upgrades of Adobe software.
So it sounds as though it'll be CS4 for 64-bit support under Windows and maybe even later to gain the same support on the Mac.

Bob.

hmm
nice, but I think it only means larger filesizes? Most camera's don't even use the full 16 bit right?

I think it has more to do with how fast Photoshop can do its magic. As I understand it Photoshop will still treat images as 16 bits per channel internally, at most, but being able to process that data in bigger chunks and also not being limited by the size of the directly addressable memory space has advantages.

It'll also allow users to edit images bigger than 4GB :)

Yep, it'll be about giving the application as much memory as the system can offer it. At the moment, Photoshop can take no more than 3GB or so, although there are still benefits of running it on a 64 bit system with lots of RAM as described in other threads here.

Still, that's great news from Adobe especially as previous comments suggested they'd stick with 32 bit for a while as the 64 bit market was too small to justify the programming investment.

I think some people think that Photoshop will support 64-bit images.
That's not what the FAQ says, it says it'll run natively on 64-bit operating systems (more precisely, 64-bit Windows Editions and Mac OS X).

Nice to see Adobe stepping up here.

They were already among some of the first movers to natively support multi-processors and multi-GPUs.

Utilizing an existing 64-bit architecture is a natural next step that too few developers have even begun to embrace.

That's good news!

Cheers :-)
