Canon 10D and photoshop CS question

[diamondeyes]

I have a quick question as to getting the raw file in Photoshop CS appear as it does it Canon's Fileviewer Utility. Is it possible? If a raw file is opened in Canon's Fileviewer utility it looks great but once I open it in Photoshop the colors are completely different. That's not on all the photos, some are quite close but some are a world apart. Can someone please help me what I'm doing wrong or what can I do to have colors the way they're supposed to be - as viewed with Canon's fileviewer utility?
ps. I'm not using Adobe RGB parameters, i"m using standard. would that make a difference?

if you capture the image in Adobe RGB you need to get them into Adobe RGB in PS CS. Do all the adjustments in ACR first, or if you are using Canon's Fileviewer, how are you saving the image, is it as a jpg, tiff, ??????

You need to maintain the colour environment from one program to another to try and maintain the colours of the image.

Remember that viewing them in a web based environment, they need to be saved as sRGB, not Adobe RGB otherwise the colours will not be displayed correctly, usually darker if saved as Adobe RGB (example).

A lot of people that work with RAW images find Capture 1 DSLR conversion program better for converting the RAW image to 16 bit TIFF files, then bring them into PS to work on them, as they can get colour balances better than in ACR or Fileviewer from Canon. Then there will be others that say the opposite.

Personally I am using Capture 1, have used the others, but find that Capture 1 does a better job for me.

Ok Here is the image I get with Canon's Fileviewer, RAW unadjusted, saved as tiff and converted to jpg through photoshop, other than convesion nothing has been altered. That's the way I see the image through Fileviewer and in the Canon 10D LCD screen


Here is the picture I got through Capture1 which is closer to Canon's Fileviewer, I also haven't adjusted nothing in Capture one, it was simply converted to tiff and than to jpg through photoshop.


And finally the last image is from RAW file opened in Photoshop, nothing changed just converted straight to jpg file. This one is way off from both of the previous editing programs.



The photo was taken using standard parameters not Adobe RGB, none of these files have been adjusted for anything, they were dorectly converted from RAW file and all three programs give me a different look and Canon's Fileviewer is the only one that looks proper.
Is there a way of making Photoshop CS open RAW file so it looks like the one in Fileviewer without making any adjustments to the image itself?

First of all, this is a topic much better off in the Digital Imaging Forum, but other than that, I'm not exactly sure what the problem is.

All of your posted images are, as you say, "untreated". That is a rather bad way to compare and judge them. There is nothing that says an "untreated" image from any format converted to jpeg should or shouldn't look like what you expect.

The beauty of RAW format and conversion software is that you can make the image look like virtually anything you want BEFORE you open it up in PS. With that in mind, I don't think it's fair to judge these programs based on an "untreated" image, but rather that program's ability to alter the appearance of the file and fine tune it to have it look the way you want.

"Untreated" images from ten different conversion programs may in fact give you ten different results. That in itself doesn't mean the programs are any better or worse than each other.

IMO PS CS's RAW conversion feature has much better tools than the Canon software that comes with the 10D.

Unfortunately, if your asking how to use that feature to correct color and edit other pic elements, I think it goes WAY beyond the scope of a forum thread. You'll simply have to pick up some good PS CS books and learn for yourself.

Adobe's "Classroom in a Book" is one that I know should help...

I don't have a problem using photoshop but I would have thought that since Canon's utility shows Raw file as it looked when it was taken so should Photoshop and all others. And if someone wanted to change the appearance at that point by adjusting whatever - they would have the opertunity at that time. That way it would be less of a pain of opening the RAW in Canon's program transfering it to tiff and then playing with the image.
Ex. I like the flower but not the background - why should I try to the the flower to look correct in Photoshop from the start when I really want to get to the business of eliminating the background? Anyways I guess I will ask Adobe for hints in this respect.

The third shot is NOT the same as the first two. How about giving us a valid example using the same file?

And finally the last image is from RAW file opened in Photoshop, nothing changed just converted straight to jpg file. This one is way off from both of the previous editing programs.

Well, yeah, most likely because it's a different image. Show us how ONE FILE looks out of all of them, then we might be able to help.

Sorry I had the other pic uploaded - it's fixed now. Anyways It's odd about this particular shot because I had yet another shot of the same flower and photoshop renders it somewhat close to Canon's I just noticed, still not exact but darker and less saturated like it does with general raw files but with this shot in particular it's WAY off and I can't figure it out and it's quite frustrating to why it is happening when the picture looks fine in the Canon util. So sorry if I confused you with a different file but it was so close that I didn't notice it. The only colors that are off are the flower colors - reads/yellows. Very odd
