Here is a portion of another thread in another forum that shows another example of the technique applied to an image: »www.dgrin.com/showthread.php?t=24919&page=2 -- I post therefore I am. |

1 edit | reply to Edit This "Color axis" might be a bit too much imagery for some people. It requires you to visualize the color gamut as a sort of cube/cone.
A similar thing can be done in Gimp... I'll try to replicate it exactly and provide a write-up.
Edit: From the DGrin info ET posted, it sounds like overlay uses Standard Deviation/Variance to determine the amount of change in a given channel... interesting. So, in most cases it would serve to increase saturation, especially when used with this method. *Paging climbers ...*
I'm perfecting the Gimp translation/comparison now. For those of you with PS Elements - you're not out of luck - Gimp has LAB functions (albeit not as thorough as PS).

| reply to Edit This I am still trying to find out exactly why this technique works the way it does. This is what I have gathered thus far.
"The color enhancement makes sense for the following reasons. When A and B are overlayed into themselves, values close to neutral (50% gray in the channels) are affected least, everything else gets pushed farther out along the color axis and so becomes more brilliant. Lighter values in the A and B channels become lighter still, darker values darker still, which means Reds become Redder, Blues bluer, etc".
That info comes from another forum. More to come I hope. -- I post therefore I am. |

| reply to Edit This A new before and after. Again I used 2 new layers on top of the background to mix the best parts of both images together into a "best of both worlds" image.

| reply to Edit This i don't see why you need lab color. as in ET's above post i made a dup layer and turned it off, then selected the 1st background layer, applied image in RGB, multiply @ 100%, then turned the 2nd layer on and adjusted opacity to to about 50%. nothing but resizing has been done.. -- www.texasbostons.com saving one at a time |

said by timcuth :PPS - Where do I go to learn about this change (layer overlay and opacity?) This quote is from the GIMP documentation. I have no idea what it means:
Opacity
The opacity of a layer determines the extent to which it lets colors from layers beneath it in the stack show through. Opacity ranges from 0 to 100, with 0 meaning complete transparency, and 100 meaning complete opacity. -- I'm up on a tightrope. One side's fear and one is hope. - Leon Russell |

| reply to depster This technique can be very flexible and can allow a great deal of control over the final appearance of an image. For example, on the before and after photos HERE I used two layers above the original background image. The 1st layer I used "Image > Apply image" and adjusted the photo to maximize the beauty of the sky. Then on the other layer I maximized the beauty of the foreground, again using "Image > Apply image". I then created a layer mask on the top layer and erased the portion of the image that needed to be removed so the best parts of the two photos would be merged. I have found that with a little tinkering and tweaking you can squeeze a lot of of a seemingly dull photo. -- I post therefore I am. |

With layer overlay |
said by 35375105 :Wouldn't this do the same as duplicating the layer, setting the layer to overlay, then adjusting the opacity of the layer? I tried your suggestion with the GIMP, using 40% opacity. Does this look about right?

PS - It reminds me of the "Clarify" action I used to use in PaintShop Pro 8.

noticed this works better on some images than others. it's also easy to lose detail. got to try using a couple of layers and % of opacity. this ones with 30% use as stated above. -- www.texasbostons.com saving one at a time |
