How do I edit RAW files from my EOS 5D Mark II in Adobe Photoshop CS 3?

EOS magazine: Adobe’s Photoshop CS3 doesn’t recognise the RAW (.CR2) files from the EOS 5D Mark II or 500D. The reason for this is that the latest releases of Adobe’s RAW file converter Adobe Camera RAW (ACR) only work with Photoshop CS4. This leaves you with three options:

1. Convert the RAW files from your EOS 5D Mark II using Digital Photo Professional into a TIFF file (16 bit is best) and edit it in Photoshop CS3.

2. Download Adobe’s Digital Negative (DNG) converter and use it to convert the .CR2 RAW file into Adobe’s Digital Negative (.dng) format, which can then be edited in Adobe Photoshop CS3.

3. Upgrade to Adobe Photoshop CS4.
