Ray, the raws will ALWAYS show an extention of CR2...this will never change. What is expected is that you create a TIFF from the RAW, but the RAW gets left alone, never to change. It could be you created the TIFF's but forgot in what folder you placed them.

RAWs are like negatives...they don't ever change.

Have a read through this:

One other area where I believe that Canon has made a mistake is that unlike with the D30 / D60 series, on the 1D and 1Ds file extensions follow the Kodak convention of giving RAW files a .TIF extension. The problem is all other programs see a file with a .TIF file as a standard TIFF graphics file and so its very easy to accidentally load and then resave a file, thus totally corrupting it. This really should be changed.

Mendel, this is no true for 1DM2, nor the 1DM2n, nor the 1DSM2.

I think Ray has the IDs, not Mark II, not sure. I didn't know about this till now, just googled a bit. Maybe he'll be back, to clarify.

I did not quite get your question, but if you use original 1Ds (not 1Ds Mark II) the files do indeed have extension TIF, but they are not TIFF files in earnest, they are RAW files. You need to use raw image converter such as DPP or CaptureOne or Adobe Camera Raw to open them and convert to real TIFF.
