SC question :D I know you love them!

As far as I am aware, REMOVING the background is NOT allowed - one can't cut out say a dark green BG and replace it with a blue one.

Quote Kirbic
there have been shots with BG removed that have been validated. The key is, was the BG a major component in the impact of the image? If it was not, then there is a chance it was not DQ'd. Also, with reference to GeneralE's post, the line has moved somewhat as we have tried to refine the idea of what constitutes moving or creating a major element.


However, hue and saturation is allowed, and selective hue and saturation in Advanced editing is allowed. So can you say select your bg and adjust it's hue and sat to turn it blue? Or even select it and create a new blue layer and add multiply or color command on it?

Is this allowed or am I missing something? Technically it's not removing but simply changing like one does to turn something black and white.

Don't even need the SC for that one; any editing that does not move pixels is allowed, in advanced, even editing of selected areas. Changing the background the way you suggest is just the opposite side of the balance beam from selective DEsaturation, and we all know that's allowed.

The crux of the matter is whether what is removed is a major element, and what it is "replaced" with. Since creation of image data (other than noise) or importing from another image is specifically NOT allowed, with the exception of minor cloning, there is the question of what it might be (legally) replaced with? There have been some "creative interpretaions" of BG replacement that have passed DQ review, usually not without significant debate. Those shots were the source of my comment quoted above.
With respect to Jon's original example, replacing a green BG with a blue one, remember that selecting the BG area and using hue/sat or channel mixer to significantly change the color is considered legal, and so this is easily achievable and in fact it's been done many times. In general, if done poorly, voters will pick up on this, and the results will not be pretty. If done with a subtle hand, there will of course be no problem.
If someone actually deletes a BG that contained significant detail, they will run the risk of having the removed area considered a major element. Also, replacement of the removed area with anything containing any detail would be considered manufacturing image data and also would be DQ'd.
So in the final assessment, radically changing, supressing, or removing/replacing a BG is not always legal nor always illegal, but depends on a lot of factors.
