Canon Digital Rebel XT - raw conversion

Canon Digital Rebel XT - raw conversion

2005-04-19 by Paul Roark

I just purchased one of these and find the Adobe Raw plug-ins do not seem to
work with it.  Adobe has a note on one of the pages that they'll support the
XT in early May.

 

The file type is *.cr2.  I thought it was the same as the 20D, but
apparently not.

 

What raw file type does the 20D use?

 

Do some other raw converters handle this file type?

 

The Canon software will convert to and RGB tiff, but it's only 8 bit.

 

My first impressions of the Digital Rebel XT are generally positive.  The
best news being the grainless images, and worst being very awkward tripod
handling (like most modern cameras).

Paul,

Try this one from Pixmantec. It's free and it's prety good.

http://www.pixmantec.com/products/rawshooter_essentials.html

Give it  a try and see what you think.

I use it most of the time with my D70.

Paul,

My XT just arrived five minutes ago...it's a really a nice camera.

Even though the XT and 20D have the same file extention - .CR2 - they are different 
formats.

Since you are using Windows there is a raw conversion software that's getting very high 
praise called Rawshooter Here's a review:

http://www.outbackphoto.com/artofraw/raw_18/essay.html

Download at this page:

http://www.pixmantec.com/products/rawshooter_essentials.html

It's free at this time and supports the XT.

Regarding the tripod handling...I use a Arca-Swiss ball head with quick release clamp. 

But it doesn't seem at this time the below vendors make the  brackets for the 
XT...hopefully soon!

They're probably basically the same format, but each camera has its own
unique color "profile" that controls the conversion. It would be nice if you
could force it to use an existing camera's profile, when a new camera comes
out that the converter doesn't know about. We used to do that in the
original Adobe Camera Raw with the 10D, by hacking the file and changing
"D60" to "10D" with a hex editor. Perhaps you can do something like that
with the current ACR, as a temporary fix.

Hopefully, cameras will eventually provide the ability to write DNG files,
at least as an option, and this problem will go away once and for all.

RawShooter Essentials is a very nice Raw Converter and is a free 
download.  They say they support the Canon Digital Rebel 350 XT.  It 
is different from ACR, but has some very nice features.

I'm very surprised to hear this. I recently bought a Powershot Pro-
1, and the software with it not only gives you 48-bit tiffs, it does 
a very good job of it, though its a bit clunkier than ACR, 
Rawshooter essentials, and C1, all of which I tried. My opinion (and 
I'm sure a lot of people wil hit the ceiling in indignation at the 
claim) is that the Canon software is better than all except C1 at 
giving you a noise-free grainless image, (and is equal to the latter)
which the Pro-1 output needs much more than the Rebel XT. And I 
think C1 is too steenkin' expensive considering how many good 
options there are!

Got a look at your Tuscon shot, absolutely georgeous! I'm assuming 
that's a scan from a print?

I found that there is a 16 bit setting.

Rawshooter has the camera lens and shooting information.  Have you found
that in your Canon program?

I'm thinking CS2 with it's raw support may be a good way to go also.  If it
does a good job, I'd like to have as few applications I need to juggle as
possible.

No, it's just a small version of the file.

Yes, you can pull up all that info in the conversion program, and it 
is preserved in the tif, so you can read it in the CS browser.

I can understand not wanting to juggle between apps a lot, though I 
haven't given CS2 much thought so far. I do hope it does better at 
raw-I think it would help a lot if everyone started using the same 
raw format.

Yes, it has a 16 bit setting but you can't set the desired output
resolution. I really suggest you try Vuescan. Be sure you have the
latest version. I've just tried it and it works better than the
program I got with my Rebel - it doesn't bother with the accompanying
jpg file, just the CRW.

How do you input the file?  Do you have the camera attached, or can it open
a raw file that is already on the hard disk?

I transfer my CRW files to my hard disc. I have a folder I've called
RAW - I am careful to move or delete these files immediately after
converting them; thus only my latest RAW files are there. I run the
conversion from there.

If you don't have Vuescan, you can get it at www.hamrick.com. There
are two versions. Given that the more expensive one ($90) has
perpetual updates I found it well worth the higher cost- he updates
it, often, a couple or three times a week. See the web
page for other differences and you may agree with me - especially the
capability to calibrate scanner and printer if you have the IT8 file.
Anyway, either version is available for a tryout.

If you download it, I suggest you install my setup file into the
Vuescan folder. It is the setup I've developed for converting my crw
files. Recall, it is not only one way. I'After installing it in your
Vuesczn folder, you load it from the file menu: load setup.I'm sending
it to you as an attachment to your email address.I also suggest you
take time to read the User Guide; it's available under help. Though
extensive, it's well written (almost) and worth the time. You might
even consider printing
it. 

I know that Vuescan can scan a sequence of negatives (e.g., strips of
35mm negatives or slides); I don't know if it can do this for RAW
files  in a single folder. It would be worthwhile exploring that. If
you do one at a time, you can set it, as I have done to open the
result in your image editor. I've set mine to open in Paint Shop Pro.
If you have Photoshop you will want to change that, If you do mmore than
one at a time, leave that field blank or Vuescan will try to open
every image in your viewer which could easily saturate your viewer.

This ought to get you started. If you have any problems let me know
(offline) and we can set up a phone call.

Regards,

Dolph
