ICC Profiles for the G6?

Does anybody know where I can get the icc profiles for the G6?

I just downloaded dcraw and I am amazed at how much clearer the pictures look after conversion and correcting the color/levels. However, since I don't have a G6 icc profile to assign to the image, correcting the colors/levels by hand is very laborious in photoshop. . .

This post convinced me to give the RAW thing a shot:

I was not satisfied with the canon's software so I gave dcraw a shot and I like what I see so far. The second and third example images int that post are its pretty interesting comparisons. The soft images on the left are typical of what I'm getting from the G6. From the simple experiments I have done with dcraw I can see that I do get better clarity, now I just need to get the icm profile for the G6. . .

Hi,
I have a G6 and have not tried shooting in the raw mode yet. However, I've used a software package to enhance my JPEG images that is just great. It is called DCE Autoenhance (http://www.mediachance​.com/dce/) from Mediachance. The program is a batch file processor that corrects many things about a photo and relies on the individual EXIF data to fine tune things. Although it is not free as the program you noted, it is a relatively low cost way to improve your images.

DCE Autoenhance seems to add "POP (enhanced clarity, saturation, etc)" to my photos.

I'm not sure what you need a G6 ICC profile for. When you convert the image from Raw, you will select a space such as Adobe RGB, sRGB, ProPhotoRGB. I use a 1DM2, 20D and G6 and have never used an ICC profile for them other then what is built into BreezeBrowser, ACR, or DPP. I always have my in camera parameter set to Adobe RGB, convert to Adobe RGB, and my working space is Adobe RGB.

scottbergerphoto,

I need an icc profile for the G6 because dcraw only interpolates the RAW data. Also, Scott, BreezeBrowser uses dcraw behind its GUI to do the conversion, so it must have a profile built in (perhaps just a simple RGB). I do not want to use the canon software to do the conversion because, as the guy says in the link from my first post:

"I have owned the Canon D60 dSLR since early 2003 and have faithfully been using the Canon bundled conversion software because is it an all-in-one solution and also because I have had the idea that the the manufacturer would surely know better how the images from their cameras should be converted.

That was until I was introduced to the DCRAW, and truly, I do not have words to describe how amazingly high quality RAW conversion software it is, . . ."



As I mentioned above I gave dcraw a try. I knew the image would be dark because I was lacking a profile but after I adjusted the levels/colors I could defiantly see the difference in clarity.

That link has some pretty convincing side-by-side examples, particularly the last too. The pics on the left were converted by canon, the ones on the right by dcraw. My guess is dcraw is using a better interpolation algorithm.



Gardenstate:

This is what the David (the developer of dcraw) has to say:
(http://www.cybercom.ne​t/~dcoffin/dcraw/)


Well, despite the convenience and ubiquity of JPEG, there are some disadvantages. JPEG is a lossy format -- to fit a big image into a small file, a lot of information is thrown away. That's why midrange and high-end digital cameras offer an alternative: Raw, unprocessed CCD data files, for which the camera manufacturer provides special decoding software.

So here is my mission: Write an ANSI C program that decodes any raw image from any digital camera on any computer running any operating system.

That program is called dcraw.c, and it's become a standard tool within and without the Open Source world. It's small (about 5000 lines), portable (standard C libraries only), free (both "gratis" and "libre"), and when used skillfully, produces better quality output than the tools provided by the camera vendor.


So basically IF this is true: "when used skillfully, [dcraw] produces better quality output than the tools provided by the camera vendor" then I want to give it a try.

Now if i could only get my hands on some icc profiles for the G6, or figure out how BreezeBrowser does it, or learn how to create them, or . . .

Thanks for your post, guys.

The only time ive ever had to use icc profiles is when choosing icc profiles for my printer and thusconfirming / having the image represented on my monitor look the same as it would in print

I thought by now several hundred people would have answered what I'm about to say so there is a remote posibility I'm absolutely mistaken!

Most canon digital cameras, unless otherwise noted use the sRGB IEC61966-2.1 color space (some cameras, like the Pro1, let you shoot in AdobeRGB also) which is by definition an ICC, which is a standard color space and you can find the color space profile "sRGB Color Space Profile.icm" in the C:/windows/system32/sp​ool/drivers/color folder. That probably will give you the results your are searching for, at least for most stuations, I assume.

Yes, you get more sharpeness with DCRAW, but also a lot of artifacts! I suggest you give RawShooter Essentials a try. It's a much better RAW converter, has a great workflow, and it's free! Also its built-in colour profile for my camera (G3) does a good enough job:

Here is the direct link to the software just noted:

great question ... i'd be happy to get it too.

i use dcraw + netpbm to get my shots from RAW and satisfied mUch! really dcraw is better than native converters (i was testing canon's, olympus's and fuji converters for their own RAW data)

yes, perhaps noise reduction is better (though dcraw has noise reduction engine) but the colors are weak mUch ...

if somebody'd help to find the issue it'd be mUch help

so DCraw is just a script code and not a exe type of program file to attach to existing programs like PS, ACDSee, etc?

cuz i was trying to find out how to download it.. and couldn't find it.

Hm .... for me, it looks only like two different shots, without sharpening and sharpened.
You could do just the same job with ACR, or use other Photoship pluging for fine-tune sharpenning.

dcraw.c is ANSII C code
you have to compile it first and after that you'll have binary file
look at dcraw homepage http://www.cybercom.ne​t/~dcoffin/dcraw/
