I got a question about the basic editing rules...
Are you allowed to do colour balance seperated to highlight/midtone/shadows? I've submitted an entry of a rather bland looking photo. I did a re-edit, after voting started, so I can't enter it anyway, but the result was MUCH better than the entry. I'm just finding out for future reference whether duotoning is allowed under basic editing rules.
It's also a tricky area, because what can be done in Photoshop with adjustment layers needs to be done with duplicated pixel layers in other paint programs. If you are achieving the same result as allowed in Photoshop, can other paint programs be used, even though to do so would require pixel-layers? Paint shop pro doesn't allow highlight blending of adjustment layers, but will allow highlight blending of duplicated and recoloured pixel layers.
I think what I've done would probably be allowable under basic editing, but the way I achieved the result did involve pixel layers as disallowed in basic editing (even though it was only duplicated and colorised). I would post the images for comments, but it's in the current challenge, so I won't.
Anyway, enough rambling from me. What do you think?

Keep in mind that while adjustment layers are legal under the basic editing rules, the blending mode must always be normal. So if the highlight/midtone/shadow re-edit you did requires a blending mode other than normal it's not legal.
I don't believe the rules say anything about a specific editing program -- they apply equally to all.
Just my interpretation, of course.

As David stated, the blending mode on an adjustment layer must remain set to "normal," and no layer masks may be used, but what you propose can be done legally within these limits. You can put in three different color balance adjustment layers, checking highlights, midtones, and shadows for the first, second, and third respectively, then adjust each to achieve desired output.
As an aside, the same thing can be done, perhaps more intuitively, with a single curves adjustment layer.
With regard to other editing programs, just because it can be done legally in PS without layers but requires layers in another program does not make layers legal for that program. Layers containing pixel data (all layers other than adjustment layers) are not allowed.

In both PSP and PS, the blend range is seperate from the blend mode, so blend mode can be Normal, and blend ranges can still be set. The difference is that PS will allow blend ranges on adjustment layers, where PSP will not. (although I think it's an implemenation detail that PS references the underying pixel layer, where PSP requires duplication). Perhaps blend ranges are not allowed anyway?

Thanks for the suggestion! It's quite obvious, but I had not thought of this.
I think I will find the curves difficult to use. I don't think in curves, although I am learning. I also find curves very touchy to adjust - 1 pixel out on the curves adjustment can make a big difference, so where possible, I prefer other controls that are more idiot proof, e.g. brightness/contrast/colour balance/highlight/midtone/shadow adjustments.
Maybe I could use the layer method to quickly achieve the result I want, and then start over and painstakingly adjust the curves to match the original result, using the RGB histogram as a guide. It might be a good learning exercise anyway.

I hear what you are saying, and I agree with applying the rules to the letter, but I'd be surprised if an image was nominated for DQ for this reason. It would be difficult to prove or even suspect the method of achieving the result when the same result is legally possible in PS. Oh wait, I just told everyone I don't have PS. Damn ;)
I would hope the judges would look at the original image and the result and see what level of editing was done. The rules are the rules to judge by, but ultimately I think it would be the judges decision as to whether the result fits the rules.

Off hand I don't recall a ruling being made public regarding setting the blending to a certain range of tones -- specifically, is it regarded as a selection or not? From previous discussions of somewhat similar topics the general concensus seems to be that a selection based on pixel content (color, tone and such) is fine, but a selection based on pixel location is foul. My thinking is; while can be viewed as a selection of sorts, the selection is based on the tone of each pixel so should be fine. That is, each and every pixel is examined to see if the adjustment should be applied or not -- thus, the adjustment is applied to the entire image equally.
The SC will again have to validate my thinking on the matter, but I got my arguement for it being legal stated first -- just in case. :p
