Asked a SC member privately but they weren't sure so I'll ask here and let everyone find out at the same time.
If I take an image and seperate the RGB layers and just work on one layer and use that layer for my entry in basic editing challenges, is that legal? Also if I change just one layer then combine them again, is that legal? I would be changing the whole layer, just like a regular shot.
Thanks!

Think the idea with the basic editing is that there you are able to do what you would be able to do in the darkroom with a film and a print. That is have some controle over the brightness and contrast and maybe hue and colorsaturation + the sharpness and other minor things and of course the croping.
You are on some gray aeria there and I dont think we should be trying to push the edges.
In the advance editing you can have much more freedom for your artistical expression and experiment more freely.

Deannda,
It seems pretty clear-cut. You can achieve what you want (examples in PS) by use of the channel mixer, without ever really separating the layers. For instance, If you want to submit an image based solely on the green channel from a color image, open the channel mixer, check the "monochrome" box, notice the output channel changes to "gray". Then move the green slider to 100% and the red and blue to zero. Or any other combination you want.
Also, if you want to do an operation on just one channel (e.g. noise reduction) you can do this by clicking on the channels tab in the layers box, selecting just the channel you want to operate on, and going from there.
In neither of these examples are you operating on "part" of an image, you are operating on individual channels of an entire image, something that has been explicitly allowed under basic editing. There has been much discussion of techniques using the channel mixer, including conversion to B+W. To my knowledge, there has never been any determination that this is not legal.
Disclaimer:

Sounds logical, but dodge and burn are are Darkroom 101 techniques, as is masking part of an image - neither are allowed here under basic editing.

I have noticed that some color channels have a lot of noise while others will be pretty clean.
Under Basic Editing rules, is it permissible to 'clean' one color channel and not the others?

It is very important here to distinguish between "Channels" and "Layers." You cannot use and Layers except Adjustment Layers in Normal mode.
However, I believe kirbic is right that you can apply an Adjustment or legal filter to any individual Channel (Red, Green, or Blue) using either the Channel Mixer, or by selecting only that Channel as active in the Channels Palette, as long as you apply the effect to the entire channel, without making any selections.
This is still a personal opinion based on past practice, but I don't believe the issue has been addressed directly since the rules were revised a while ago. I'll try and get more opinions for you ... in the meantime, you might want to prepare two versions of any possible entry. |
