How to open 20D RAW images with Adboe Camera Raw
Aug 28, 2004

When the 10D arrived it wasn't supported by Adobe, but someone figured out you could use a hex-editor and edit the Adobe Raw Converter-filter. I just tried to do the same with 20D - and it works pretty good. The saved WB doesn't seem to work so good, but the WB-presets seems to be ok. Anyway, here's how to do it:

1. Close Photoshop if it's open.

2. If you don't have the latest Camera Raw (2.2, wich supports the 1D Mark II): Download the update from Adobe's homepage and copy the Camera Raw.8bi-file to your Plug-Ins/File Formats-directory, replacing the original.

3. Make a backup of the file you just copied.

4. Open the Camera Raw.8bi-file with a hex-editor (Ultraedit is a good one; ). Search for "Canon EOS-1D Mark II", replace it with: "Canon EOS 20D". Replace the "Mark II"-part with seven zero-bytes.

5. Start Photoshop and open up some 20D RAW-files and play with them.

You can find some RAW-files here:
