Canon RAW files and their conversion

2004-06-24 by adolphamster

The more I read about it the less I understand it. I'm using a Canon
Rebel. For highest image quality it produces a "RAW" image. The files
themselves are of *.CRW type. I run them through a Canon supplied
program which converts the RAW files to *.tif files. When I open the
*.tif files I actually get two images, one high resolution, one low
resolution. I have no use for the latter but have to take the time to
open the parent file and then delete the unwanted file.

Maybe someonne can explain to me, in simple terms, what this is all
about and how, if possible, I can rid the master files of the unwanted
low resolution .tif file.

Thank you very much.

From what I have read, there is no way to get rid of the low-res image
in-camera.  I have also read that the Canon raw software is pretty bad.  I
have had great luck making b&w inkjet prints from the Canon.  I use the
Capture One raw converter, which allows you to work in b&w for the
conversion.  In opening the images, I never see the low-res image, just the
converted tif file.  It's probably somewhere on the HD.  The converted image
is still color in tif format, but easily converted to mono and toned in
Photokit or whatever.  I also tone the grayscale images in ImagePrint which
also works well.  I think this is a great camera for b&w work.  I have been
doing some b&w infrared panoramas (Kiwi pano head)and the R72 IR filter.
They look good so far.  More info than you wanted, I'm sure.  I would just
get the Capture One raw converter.  Also I have used the raw converter in
Photoshop 8, which is OK too.  Either one is fast and easy once you get the
hang of it.

That's a characteristic of the conversion program. Other programs don't
necessarily do this. And if you have Photoshop CS, you can just open the raw
files directly. If you don't, you should. ;-)

Another "should": join the Canon 300D Yahoo group. They probably have lots
of talk about raw conversion--I know the Canon 10D group does, since that's
what I shoot. In fact, you might want to join the 10D group anyway, since
it's about twice as big, and they're almost the same camera anyway.
