Small RAW and Photoshop

<p>Does anyone know why Photoshop CS4 is not able to open a s-RAW file generated by a 5DM2? Although its file name extension is CR2 like the standard Canon files, something is happening that I cannot open the files.<br>

Thanks</p>

<p>New dslr models typically require an update to the raw processing software. The file extension may not have changed, but the "internals" of the file has. Check with Adobe.</p>

<p>Out of interest - and to save unnecessary "rework" - what did you find out from Google before asking here?<br /></p>

<p>One other thing, once Adobe Camera Raw has decided the file is not compatible, it might persist in this behaviour even after you apply the update. In this event you need to refresh the cache for that folder. That function's in one the pulldowns, I forget which.</p>

<p>I have Photoshop CS4 and a Canon 1D MKIII and can view and edit the SRAW files. I assume they are the same "design" files as the 5D2. I have Adobe Camera RAW version 5.3. Do you have the latest ACR version? </p>

<p>Steve, thanks the new ACR solved the problem.</p>

<p>Nunes, I have found significant color variance betten full resolution and SRAW files. I suggest you take some test comparision shots before using the SRAW files.</p>

<p>I think Adobe does not fully support sRAW files yet, sometimes I get very strange artifacts and color shifts with LR 2.3 and sRAW files.</p>
