Hello!

After conversion from RGB to CMYK in Photoshop, colors on my picture becomes unacceptable faded. If I save this graphic, and open it in ACDSee image viewer, colors are very bright! I suppose it’s a Photoshop configuration problem. Can somebody help my resolve this problem in a simple way? I use Photoshop CS2 and Windows XP Home.

Regards,
Pit

It’s not a Photoshop problem.

You probably have colours in your RGB document that are out of the CMYK gammut. (your mention of very bright colours makes this very likely)

Seems, last versions of ACDSee support color management. If so, just embed CMYK profile in the image when saving in Photoshop. Otherwise, colors will be wrong represented in ACDSee.

P.S. As for me, I use freeware FastStone Image Viewer <http://www.faststone.org/FSViewerDetail.htm> that has built-in CMS (for JPG and TIFF).

Thanks for the link for FastStone Pipkin, I used to use Irfanview as my image viewer; but lamentably, it does not correctly show CMYK images.

Spoke to soon, maybe the pro version of FastStone is Colour managed, but the free version isn’t – CMYK images are not displayed correctly. The search for a decent image viewer continues, I may give acdsee a try.

stevent, freeware version of FastStone Image Viewer (latest is 2.7 beta) supports CMS (in full screen, not in thumbs).
ICC profile must be embedded into image, of course.

Bridge doesn’t have full screen preview

Ctrl+L

using it as image viewer is not good decision

Bridge is so versatile and customizable, I even use it for previewing to my clients.

You can have more than one "browser" open at once. You can even show a RAW file as a black and white with one (right) click without even opening it in ACR!.

Once you really get to know Bridge it out performs just about every other "image viewer" I have tried. And this is just version one! Can’t wait for Bridge 2 – or for Lightroom to come of age.

Bridge is way too slow and high maintenance as an image viewer – bear in mind that this is not just for the PC with Photoshop on.

You can’t seriously compare it to something like Irfanview (speedwise)?

Bridge is sluggish, non-intuitive and can be downright dangerous.

Just browse the Bridge forum.

Fingers crossed for Version 2.0!

Not on my system (nothing special, just clean and well maintained)

non-intuitive and…

Don’t know how you can say that, especially when you consider it follows most of Photoshop’s conventions – not to mention it being customizable.

Fingers crossed for Version 2.0!

I agree. There are some issues which I’m pretty sure will be addressed in the next version. But I dread to think how much longer my workflow would be now if it wasn’t for Bridge.

…can be downright dangerous

Did I not mention I wear a crash hat!?

Seriously though John, when I first started using Bridge, I was one of the first on the Bridge forum to bring up things like: "files disappearing when dragging and dropping". By and large, all those major issues have been addressed by the Bridge team who, to their credit, did take notice, did offer encouraging feedback, and did finally come through with the updates.

Not only that, I have learned to tame the beast. It is working for me now.

Let me just illustrate how I use it in my workflow:

Working with RAW files, I can present the client with a slide show (fades would be nice, but it’ll follow I’m sure) of all their pictures, within 30 minutes of a studio sitting.

In this time I have edited for keepers, renamed, corrected for exposure and/or tonal variation, and even performed a crop where necessary.

I present the client with two Bridge windows side-by-side in filmstrip mode for her to compare two images at a time. As she makes her choice, I just hit the "0" key to remove the unwanted one. Because both windows are set to show "1 or more Stars", the rejected images disappear from view. At the same time I can tag her favorites with two, three or more stars to rate them in her shortlist.

In Thumbnails view, I can, for instance, show all the three star rated images by pressing Ctrl+Alt+3 – and so on.

"Can I see that one in black and white?" A right-click and select B&W from my saved settings, turns the preview black and white in less than two seconds. Same for Sepia, Blue Tone, Cross-processed, Bleached-out, or any other of my predetermined ACR settings.

All without even opening Photoshop! No other "image viewer" could hack it for me.

I can see that it’s fine for that but, on the other hand, there are a lot of reasons why it isn’t even a full replacement for Windows Explorer!

I know, I know — there are 101 things it can do that Windows Explorer can’t. That doesn’t make it right!

Also: It takes 7 to 10 seconds to open on my (fast) machine whereas Windows Explorer with Win-key + E is instantaneous. That alone debars it from being an Explorer substitute.

Yes. It works. Pardon my oblivion.

Since I don’t use Bridge. Maybe I am wrong. I have to meet it more intently…

John, me awld mate. We’re going to have to agree to disagree on this one. 🙂

I won’t even mention the fact Explorer can’t (safely) display PSD thumbnails. (whoops, I just did!)

Just checked: My Bridge took a fraction over two Seconds to open from cold (a directory containing 104 RAW files).

The way I look at it, I’m not really growing old during that time – or even four times that time! And anyway, I can be gainfully employed for 7 – 10 seconds looking at this month’s view of my Kylie calendar.

It’s quite irrelevant in my case, however, as both computers are on 24/7 and, apart from defrag time, my Imaging workstation has Photoshop and Bridge running pretty much all the time.

Chris.

If I had the type of work you do Chris, it would be different.

Not being a professional shooter, I never end up with dozens of folders, each with 100s of photographs, to sort – and I don’t (yet) deal in raw.

In Bridge I just miss the easy to use file and folder management capabilities that I have in Explorer.

Lack of PSD thumbnails is not a problem now.
