You were mistaken..

A Raw file has no color at all. It just contains sensor data. It is up to the Raw converter program to assign colors to pixels based on the sensor data. Each converter program has it's own way of assigning colors, so each gives it's own color renditions. This is one of the reasons that there are a couple of dozen different Raw converters available: different people like different color renditions...

Well, I have zero expirience with RAW and how Photoshop and Mac viewer are supposed to handle it, but to me it looks like white balance problem.Look, at those specular highlights, - they're yellow in PS and white in viewer..

Again, as I understand it, RAW means just that, - no in-camera postpro of any sort, including white balance..

So, Photoshop did it right, - it dumbly obeyed user, hoping that our superior natural intelligence would decide on better color balance..

While wiewer did apply it's own correction (I don't like when programs are too smart and do what they weren't asked for...).

If you are a beginner, probably not. Here' s a link to an introduction to color management..

A detailed diagnosis of your particular problem is difficult without much more info and is beyond the scope of a concise reply..

Ok, I use a Mac and all the usual tools with a 400D (Rebel XTi)..

Lately, I got a new toy and wanted to make some serious photographywith my 400D. So I selected the raw mode for the first time andstarted to shoot under some different natural lights..

When I started to import the pictures on my Mac, I opened somepictures with Photoshop (CS2) and I almost fell from my seat! Whatare those colors? What the heck is going on?.

Then, I simply opened some pictures with Preview (this is a standardapplication included with every Mac and it can open naturally rawfiles) and they looked ok. At least, the problem doesn't come fromthe 400D!.

To see what I mean, the following pictures represent a copy screen ofPhotoshop and Preview:.

Let me tell you, this bike is red. Take it as you want: Ferrari-red,blood-red, etc. but not orange!.

I thought raw pictures were the best in order to keep the right colorbut it looks like that Photoshop has it's own way of treating it!.

Do you have any suggestions in order to have a more decent treatmentof my raw pictures?.

'People just don't understand what is involved in this. This an art-form! You know, I think that most people just think that I hold a camera and point at stuff, but there is a *heck* of a lot more to it than just that.' Larry, the cameraman character in the movie 'Groundhog Day'.

P.S. 'Photoshop' is NOT a verb..

As someone else has directed you to colour management info, and another to white balance I'll skip that..

However, the expectation that any two applications will produce identical results is basically wrong. All applications, mediums, display devices and what ever, will map the colours in the image to the colours they use. All that's stored in a file is a set of numbers ( brightness levels relative to an internal standard ) and ( usually, but not always ) a reference to the colour space ( the standard ) the numbers relate to..

Even if two devices/applications understand the same colour space, they may not identically display/process the image..

Even with calibrated devices and high quality colour profiles perfect colour representation is almost impossible. All you can ever get is close, very close sometimes, but that's harder than it might seem..

Finally, given the choice between Photoshop and Mac Preview I'd expect Photoshop to be more faithful. Preview is exactly what it says - a general purpose application to display a preview of something. Photoshop is a professional photo processing application..

Thanks all for those advices, recommendations, corrections... I appreciate..

Could you suggest a few programs that you use when you take care of raw pictures? I feel that I still have a lot to learn in the "digital area" photography..

[off topic].

When I got my first digital camera, I thought "Whouuuaaa, I'll be free to do lot of labs in order to get the pictures I want!".

Now I realize that you can spend 3 or 4 times more time in post-treatment, post-production, post-tunning and thats a bit frustrating even if it opens thousand new ways of "showing" you pictures..

Anyway, thanks again for those comments! I'll try to work out some pictures and I'll get back to you in order to learn more!.
