Changing that setting was aparently a BAD idea!

CR2 files are created when you shoot RAW files. Your computer cannot read them without a Canon RAW plugin in whatever image processing software you're using.

Your camera can be set to record in JPEG, RAW or JPEG and RAW.

I hope this has helped you, if not then please add a comment to explain what additional information you'd like regarding this problem but otherwise please take a moment to rate my answer.

hi there,

you can use a memory card reader, if your camera software was faulty to use..

Thank you

download "EOS Utility" for the Mac from USA.Canon.com website or just use a card reader.

Try changing the "communication" setting on the camera from "PC Computer" to "PTP"
Menu > Tools2 (wrench/hammer/2) Communication = Print/PTP

1st, make sure the camera is in the Creative zone P, TV, AV, M or A-Dep. I have made this mistake many time and everytime I forget I moved the dial.

If dial is in the Creative Zone and still no RAW option then have the camera format the card, if that doesn't work do the following:

Turn off camera,
Remove lens,
Put on body cap.
Remove CF Card
Remove Battery
Let sit for about 30 minutes.
Put battery back in.
Put CF Card back in
Turn camera on
Put camera in Creative Zone
Push Menu button
Push Set button twice and check if RAW is now an option

If not then you can try the clear all settings function in the Set-Up 2 menu. Push the menu button then the left arrow button arrow down to the clear settings line push set the clear all functions.

If this doesn't help then I would say carry it to your nearest Canon Dealer that offers cleaning and service.

Double check the wb settings in camera, (and be sure to check WB Shift) I'd suggest adding a Blue shift to your images to compensate for the Amber until you find something thats a decent trade off, if you can't eliminate the amber shift.

In order to be able to select RAW, you have to be in P, Tv, Av, or M. RAW is not an option in Auto or any of the Basic Modes.

Make sure that the mode dial is not set to one of the 'Basic Zones', i.e. Auto, Portrait, Landscape, etc. You should be able to select RAW or RAW+L in P, Tv, Av, M, or A-DEP.

Well, that worked perfectly. Turn on your Rebel XT camera and under Menu then Tools go to Communication and set it to Print/PTP. Thank you to all you very smart people!

Dust is something that will need to be addressed. Get a Visual Dust brush and learn how to use it. You can help reduce dust by 1) changing lenses with the camera body facing down and 2) turning off your camera when changing lenses.
