Linear Workflow Action - Need Beta Testers

[DMahoney]

One last thing....(still reading through my notes!).

Thanks very much for taking the time!

I mentioned that I was seeing more and more problems with the Canon
conversion. Some of these issues are sadly inherited by the linear
conversion. With the 10D, at least, there is a green channel
"weirdness" that can show up in odd places. It has to do with the
white balance routines. Capture One is extremely clean in this
regard. It's been widely reported.

Since Paul released a new version of his Linear Workflow action yesterday, I took a whole bunch of raws and converted them to give his action a workout. His recommended conversion is EVU, so I used that. I did notice some things that I will have to go back and investigate further, doing some comparisons.

OK, I next cropped out a small portion at 100% to show that the
linear is surely capable of bringing out some more detail than the
non-linear. Compare the window at the far right.

Yup. Both the linear and c1 seem to bring out a bit more detail. Something that I am sure would be noticeable on larger prints!

But, but, but.... more importantly, Capture One doesn't have the
little green/blue "uglies" that you can see in the Canon
conversions. Look at the clapboards right above the center window
in the second image. Is this unique to the 10D? I don't know. It
surely doesn't show in D30, D60, or 1D files I've seen.

Does the 300D show the same thing? Don't know.

Based on the 38 pics I worked with last night, I would say YES. I noticed this "effect" in a couple pictures, and in one at least, it was fairly distracting. I think it would be noticeable in 8x10s. 4x6s, maybe, maybe not. I should print one to see. Neither c1 nor ACR show this in a conversion of the same file.

Is it important? Only you can decide.

If this pic ends up being a small web-sized version or a small 4x6 print, no, of course not. No point worrying about something you will never see. But if you are going to print large or view bigger versions of the photo, then for me at least, the answer is yes, it IS important. I would prefer to get the cleanest picture I can. In MOST of the photos I played with last night, I didn't have too many issues, but I need to do more, direct comparisons to be sure.

He's NOT governed by myth or guesswork? NOOO!! And here I thought I
was doing pretty good... you mean someone can actually get a HANDLE
on all this stuff?!

Well, actually I am governed by myth and guesswork!. Truly. Yes!
Please?

Whew! You ARE mortal! Of course, your "guesswork" is probably a much more informed guesswork than the rest of us, but that's okay! As long as it's guesswork, I can still relate!

Great, even MORE money to spend on software! DOES IT EVER END???!!!

Nope, never...

Dang... I need a bigger wallet. I hope some day I will be able to actually AFFORD all this stuff, instead of putting myself in the poorhouse all the time!

$30 US. If you select the "ETC profiles" section on the left menu,
and then open the article about your camera, you will find samples
for most profiles, several for some. The 300D and 10D are extremely
identical, and in sRGB you can't even measure any difference
between them.

AHH!! That's the problem, there AREN'T any examples in the 300D section! I never looked at the 10D section, where I found an example. Interesting results. I am going to have to look at it further I guess. Thanks for pointing that out!
