This topic was inspired by this feed back thread in Make it a Mega Shot forum.
Friends who like the colors in my photos, often ask me about my Post processing steps and methods. The answer is the fact that there is little Post processing for colors, if any at all. I do all my color processing at the time of conversion. I limit post processing to sharpening and some color tweaking, if the image needs some. Most of the time spent on an image is in conversion and in sharpening afterwards.
The following images are screen copies of this particular Frog image, in Adobe ACR. The first screen shot shows the frog as it was recorded by the camera raw and the last one is the finished product. As you can see, there was really little work done in post processing, not much sharpening either and the image was captured at F38!
I use the curve function a lot and so I do the Calibrate page, the last page in ACR interface. Think of the sliders in the Calibrate page, as channel mixers and you will soon find the relationship between the different sliders.
Hope that helps,
Cyrus.

Thanks, Cyrus, for the demonstration. I am very new to RAW processing and hadn't considered some of these options at all. Then, I don't do that much color tweaking but this inspires me to try it out.

Good example how change in WB affects the image drastically not only in color temperature.

Wow, that's really interesting Cyrus. Is Adobe ACR something that comes with photoshop CS2, or is it an extra product? I shot in raw once and saw no way to convert with photoshop elements. But I just ordered CS2 from ebay, so maybe I have it now. I'm hoping!

Thank you guys.
Linda, once you get your CS2, you still have to add the plugin for the raw converter, it's easy. Just let us knnow when you have your copy.

looks good. I never venture into the calibrate tab, but I probably do similiar stuff in PP. I just downloaded Capture-One Pro demo the other day and have been getting great results! My pockets arn't deep enough for that price tag on a raw converter alone.

Aha - I've never used the calibrate tab much either - nice tip!

Robert,
Not many people do. you may find the relationship between the sliders, strange for a while but you will soon figure out.

Brian,
You do know that if you have CS or CS2, the raw converter is free, I'm sure you may know that already.
Going back to our earlier communication about the clipped shadows in your dragonfly shot, notice how the contrast is set to zero on the first page of converter above.

Yea I use CS3 Beta until release. I've been trying to leave contrast and shadow sliders alone and doing that in the curves tab lately.

Thanks, very generous disclosure Cyrus. In elements4 and Canon 350D I don't see the lens, curve and calibrate tabs :-(

Having found the calibrate tab in CS2, where do I find a tree frog?
admin
Cyrus khamak 8 years ago
LOL,
Robert,
they sell them at your local pet store. I have found the best sources of amphibians in UK, for some reason!
Some of the most interesting frogs to look for, would be, Red eye frog, White's from, Monkey frog and the Waxy tree frog. The waxy tree frog, of which we have a shot in Mega Shot pool, is very interesting and very expensive as well and you may want to skip on that one!

HERE, the is a waxy tree frog and it is so cool looking frog. But look for the White's tree frog and they are cool looking too and are very cheap as well, about 10 British pounds.

I'll have to dig around in Elements 5's RAW converter to see what I can do. I don't have the $$$ for CS2, but maybe I can get close with the software that I have. Thanks Cyrus!!

OK, I don't think I'm at your level of skill Cyrus, but I spent more time in the RAW converter adjusting the white balance and the contrast. I don't have the curves adjustment in the Elements RAW converter but I can manipulate it once I get it into the main editor. Here's my latest attempt:

John,
This is great, both the image and warmer tones. I also see a bit of softness in your lighting compared to the other ones.
I'm going to Flickr mail you about something

Cyrus, I have read the above discussion carefully. I'm very new in RAW. And I work with Elements 5. I post the original file and the converted one.
Most of work was done during conversion. What do you think?
I don't understand what's about color luminance. Can you help?
Thanks. ILY

I would like to say, by conversion we refer to what you get after you
process the raw file and BEFORE you do any post processing to it.
I like what you have done in the post processing with this flower. You
have increased the contrast and sharpness quite well and have
given the petals a nice and crisp look. What does not work as well for
me, is the dark patch under the flower and some clipped shadows
which has killed the detail quite a bit. In a shot like this, it's good to
have some transition in colors as you go from highlights to mid
tones and shadows.
.
Chroma and luminance are two of the properties of light. Chroma is
what defines a color and luminosity is the how bright the color is.
You can get noise in color and also in the brightness of the color or
luminance. Color noise is the variation or fluctuation in color (like you
may see greens and blues or black patches in the darker part of a
red petal) Luminance noise is the variation in the brightness of color.
If you turn a photo, with high chroma noise and high luminance
noire, to black and white, you will see less of the effect of the chroma
noise and more of luminance noise.
hope that helps

Thanks, Nil mutant, for bringing this thread back up...I hadn't seen it
before. Very interesting. As for your question, I know that you can open
jpegs in ACR, but that is the most of what I know. Hopefully others will
have more for you.

Hello Niel,
Thanks for bringing this up.

A raw file, is the equivalent of a film negative, with the old film
cameras. It is a bunch of o and 1 as the digital sensor sees and
interprets your scene, when you take a photograph. It has to be
converted into an image, through a software which can understand
the raw file, such as ACR (Adobe Raw Converter)
Taking a photo in Raw format, is a good practice, as it leaves room
for a lot of adjustments, AFTER you have taken the photo. The most
important adjustments available in a raw file are the following:
1_ you can adjust your exposure
2_you can adjust your WB (White Balance) and let me know if you
need and explanation for WB.
3_you can calibrate your colors to get close to the real thing, or improvise.
4_you get a lot more information in a Raw file than you get in a jpg file
5_.....
You can't do much to adjust your exposure in a jpg file but you can do
a lot of other adjustment in an application such as Photoshop. One
to remeber is the fact that all the adjustments you make in a jpg file
is destructive to the integrity of your photo, while doing it in Raw, it is
NOT.
ONE FINAL NOTE, you need to have a DSLR )Digital; Single Lens
Reflex, the cameras where you can change the lens) OR some of the
higher end Point and shoot cameras. I don't believe you can shoot in
raw, with your camera but I could be wrong.
