RGB Setting: What's the Best?


I have the Canon Rebel xt and I'm wondering, should I set it to sRGB or Adobe RGB? I use elements 3.0 and I'd like to know what is better to have my camera set to?

  These are color spaces, and should be selected based on your working environment from data capture through the printing process. Adobe RGB has a wider color gamut than sRGB, and thus would be the better choice.
However, it is my understanding that some Windows versions default to sRGB, which may or may not present an issue in this matter. If you can work in Adobe RGB from camera to print-ready, it is by far the better choice.

  I was also wondering which to use - I have Windows XP Pro. Any suggestions as to which is better for XP Pro. Many thanks.

  Robyn: In a nutshell, Adobe RGB is ideal if you plan to print your images. And sRGB is ideal for images for Internet use.
But as Michael said, not all image editing programs support the Adobe RGB format. All Adobe programs do. So, it depends on what imaging software you use, and not what operating system (XP) that you have.

  Tks Peter. I have Photoshop CS (but don't quite know what I'm doing with it yet!) I also just use Microsoft Picture Editor, and also have the program my Canon Eos3D came with (I multi-task hey??). So ... some pix are uploaded to the net, others are saved in albums on my laptop, others will/might be printed! So ... to be on the safe side, would you suggest sRGB which would cover me for most things? Sorry to sound confused - I am :) LOL

  Robyn: If you use 90 percent of your images for the Web or e-mail, just set your camera to sRGB. That's fine for prints you order from labs too. (They work with sRGB files.)
But if you often want to print images yourself, on your own inkjet printer, set the camera to Adobe RGB. You can easily convert those images to sRGB for Web or e-mail use. Here's how:
1. Set your camera to shoot in Adobe RGB color space.
2. When you open the image in Photoshop, retain Adobe RGB if a pop up asks you if you want to do so.
3. These images will be perfect for printing.
4. If you want to use some images for the Web or e-mail ....
A) Take an image, downsize it, and Save As JPEG. If the large file was a JPEG too, give the small file a new name.
e.g. Large file was: Mary_at_Beach.jpg
Name the small file Mary_at_Beach_Web.jpg
B) Now, convert the small file to sRGB.
From the items at the top of your screen, select IMAGE.
Then, IMAGE ... MODE ... CONVERT TO PROFILE.
Select sRGB from the list and click OK.

Your small file (for Web or e-mail use) is now in the sRGB color space.
