One could be called "Pop" through RGB, and the other could be called "Pop" through LAB: that simple. IMO.
I have been using Lab the last few days as a way of getting things posted in some sort of reasonable time frame with a bit less stress to me.
Rutt always said that LAB was fast and easy, well, it never sounded like that to me. But I have taken the easiest, most basic part of it, applied it to my images, boosted the subsequent saturation by the number of 15, used the USM, didn't frame and uploaded to smugmug. Yesterday I shot over 400 photos. So far, I have posted two series.
And they aren't much worse than if I had sweated over them for hours in layers, etc. And they are being seen.
I just wanted to extol the virtues of LAB, regardless of how complicated it can be made, it can also be used in a fast simple manner.
I think the user can determine, better, number one, number two, etc.
One is just RGB and the other is LAB to me.
If one wanted to title the whole thing it could be titled something like: "Working in colorspaces found on photoshop", or something like that. But, to be honest, I think the very word "colorspaces" is something scary to some, it was to me. I think simplicity is key here.
RGB Curves yield pop, a how to.......
LAB Curves yield pop, a how to...........
After all is said and done, it is the sweet tea.
