I just bought the Canon XTi DSLR over the weekend and went, as one would expect, out and shot oh maybe 4 gigs of pictures in places I have shot repeatedly over the years.

I had not stopped to look at the "Digital Photo Professional" software that Canon provided with the camera but I knew I would have to pre-process any images I shot in RAW CR2 format due to the fact that I have CS version of Photoshop. I was disappointed to find that the Canon software was so limited in its capabilities especially with respect to RAW adjusting of exposure. I had always done this in CS with its support of Canon’s original RAW images.

In any event, now I find myself faced with restricted ability to adjust my exposures and color before transferring my images to CS. I don’t want to shell out the $$$ to upgrade to CS2 when CS3 is right around the corner. I know I can accomplish the same exposure adjustments in CS on a .psd, .jpg or .tif image but am not as versed in the use of those controls anymore and as I remember accomplishing the same things using the curves and other controls is much more entailed than is the RAW processing in CS.

So, I am faced with a small problem that presents the following questions.

1. Not having used .tif much and only using .jpg to save images that are provided the customer I am a little fearful that if I save from the Canon software to either of these formats I will loose image quality. Can anybody expand on this please? In CS I always worked in and saved in .psd until I was finished.

2. If I export from Canon directly to CS the image comes into CS how? As a .tif? a .jpg?

3. Am I so misinformed about image quality and format that I am making life hard on myself? <Silly Grin>

4. Is CR2 RAW better than CRW RAW or is this just a new format that Canon can milk some more licensing fees from Adobe over?

Too many negative thoughts that I don’t feel like to be part of my response <bg>.

1. Yes, CS3 will be out pretty soon so I would suggest you to wait for its release. Or if you didn’t die because of CS for years then few more days/weeks won’t cause much more problem.

– I have never care for TIF (even I have read the same story over and over for over decade), and I have been using JPG before PSD and RAW were born. It didn’t cause much problem when the number of pixel was much lower and JPG wasn’t as good as current (or most graphic programs now does JPG much better than before).

And now with much larger pixel, and I don’t re-save JPG more than 1-2 times, I don’t see few lousy pixels can effect 9-10+MegaPixel image.

So, enjoy whatever you have and put all the worrying aside, and lets Canon & Adobe deal with each other. Yes, I am using CS2 and will upgrade to CS3 when it’s available.

Working in TIFF does not cause you to loose any image quality compared to PSD. Both support the same things and both aare lossless.

2. If I export from Canon directly to CS the image comes into CS how? As a .tif? a .jpg?

You decide that, so I’d advise to use TIFF. If you use JPEG, you do loose image quality.

3. Am I so misinformed about image quality and format that I am making life hard on myself? <Silly Grin>

Yes. 😉

Adobe doesn’t pay royalties to Canon for opening CR2 files. They would only have to pay royalties if Photoshop could WRITE to CR2.

PS CS can support the XTi via the DNG route. The (free) 3.7 DNG Converter can create a folder full of DNGs from those CR2s, and ACR
2.4 with PS CS can then process them.
