error on CR2 file -...File Format Mudule Cannot Parse the File

[sterne200]

Anyone know of this one - Photoshop CS6 says to one Canon CR2 file out of about 600 taken that day

Could Not Complete Your Request Because the File Format Module Cannot Parse the File.

The corresponding jpeg to that file can be opened, the CR2 can be opened in other programs Viewers - Windows picture viewer, Irfanview, etc.

It can even be renamed there as a TIF and that will open in Photoshop, but then of course one doesn't have access to the RAW file controls.

Anyone ever gotten this, know a workaround or a cause ?

Thanks,

Sterne

What does this TIFF look like? If it looks normal, it's not a raw file. A genuine raw file, before processing, is a very dark and very tonally compressed grayscale image.

Thanks,  I know the Tiff file is not a RAW file. I was just saying that a viewer such as Irfanview which would allow me to open the CR2, would also allow me to then save it as a Tiff - which could then be opened in Photoshop - but without the ability to make the adjustments one can to a RAW file.

What happens when you open it with Canon Digital Photo Professional?

That's a good question - as I do not have it installed I don't know if it would open there. Thanks for the thought.

OK, but it needs to be clear that these other apps you mention - Irfanview, Windows photo viewer - don't show you the raw data. They show you the camera-processed embedded jpeg. That's such a small part of the CR2 file that it can be perfectly fine even if the raw file is corrupt.

Which is what I think it is. It can easily happen with a flaky cable or card reader. I've seen it myself a couple of times, and the very first thing I do when that happens, is to throw the card reader and cable and get new ones.

Thank you. I agree that is is mostly a bad sector on the flash card or something.  I was just wondering since the image part of it is viable to another programs / apps, if perhaps someone knew what the hiccup was on the RAW end and how possibly to correct it to make it readable as a RAW file in Photoshop.

I also think the suggestion to try it in Canons software makes sense.
