Convert Cr2 To Jpg Mac Online
First, I am posting in this forum because I need help for a problem that I think only experienced photographers could answer, even though I don't use Aprerture (or iPhoto).
I borrowed a friend's EOS-1D Mark II and shot using the camera raw format. My Mac could see the files and even open them in Preview. I am using PShop CS3 on a Mac running 10.5. Because of this, I have to use Adobe DNG converter so I could open them in Photoshop. I cannot afford to upgrade either the OS or Photoshop right now.
I decided to start shooting in the raw format with my EOS Rebel T2i. I formatted an SD card and changed the camera's settings to shoot RAW. When I moved the files to my Mac to open them, instead of thumbnail previews, I saw 'exec' icons, even though the file extension says .CR2. I tried to convert them with DNG Converter, and it said there were no recognizable files to convert. I changed the setting in the camera to save the file as both a RAW and jpeg file. The CR2 file was still not recognized, but the jpeg is.
I thought installing 'RAW Camera Update 2.7' from Apple's website would solve the problem. (Currently, 'RAW Camera Update 2.1.2' is in my Library.) The problem is that ver. 2.7 requires either Aperture or iPhoto 9, or my Mac won't install it. I don't think the issue is with the 3rd party software, because the Mac 'sees' the image files taken with the Mark II, but not the T2i.
I am stumped.

Cr2 File To Jpg Mac
| Name | CR2 | JPEG |
| Full name | Canon RAW version 2 | JPEG - Joint Photographic Experts Group |
| File extension | .cr2 | .jpg, .jpeg, .jpe |
| MIME type | image/cr2 | image/jpeg |
| Developed by | Canon Inc. | Joint Photographic Experts Group |
| Type of format | Image File | |
| Description | The Canon RAW version 2 (cr2) format is a RAW format created by Canon for storing digital images. This does not contain a ready to view picture like a JPG or PNG file, it is used to store information directly coming from the sensor. You can choose to store your pictures in RAW format which gives you the benefit of being able to do a lot of post processing on the file, if you tried to do this with JPEG, this would be difficult and would likely result in a quality loss. | JPEG is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. |
| Technical details | RAW files are the best quality to size ratio that a photograph can be stored in, primarily because each colour is recorded in either 12 or 14 bits and a lossless compression is used. The CR2 takes over from Canon's previous format - CRW and is used by the Canon 350D, 1D, G9 and 20D models. | |
