Canon cameras have been around for a while.
Modern variants produce
.CR3, most mainstream variants produced
But the first Canon raws were
Those CRW raws may be either 10 bits or 12 bits (or 8 and 10? does not matter here).
There is one more really important parameter - the decoding table number.
There are ONLY three tables - 0, 1 and 2.
You can check which table is used in your
.CRW: (this may differ image-to-image)
$ exiftool -DecoderTableNumber raw.pixls.us-unique/Canon/PowerShot\ G1/crw_1693.crw Decoder Table Number : 1
And here comes the problem.
Apparently, on the whole raw.pixls.us, we only have samples with table=1 and table=0,
but none with table=2…
Perhaps someone here (used to) own a camera that produced
and may have some such raws in the archive
It would be great if you could look if anyone has a raw with
table=2, one that you could contribute to https://raw.pixls.us/
For reference, you can use the following command to find the wanted images:
$ find -iname *.crw -print0 | xargs -0 exiftool -DecoderTableNumber -if '$DecoderTableNumber eq "2"'
Bonus for those who did read the whole post: the CRW situation on RPU is really saddening.
Please do check whether we already have a sample for your camera under CC0 license.
It is highly likely that we do not. Samples wanted
