Erlik, If you are just matching sky to a clean horizon, compositing two shots taken from the same rock or patch of meadow shouldn't be tricky. If you are trying to overlay a complex shape such as a person, it would be harder. Thank goodness our sun doesn't move very fast! To bring out the mist in #2, I made a duplicate layer and cut just the sky. I raised the contrast, but that also saturates an image, so I softened that. Changing the blend modes tells PhotoShop to calculate and weight pixels in various ways... multiply gave the best result. Layers can also be faded and/or made less opaque, so it is possible to be very subtle if you are trying to coax a bit more detail. This is easier than taking 2 exposures, but can't fix major flaws or places where there is no detail at all. :sigh: When you remember the deep blue sky of the mountains, looking at images where it is washed out to whiteness is disappointing. I'd read that Ansel Adams used to bake his prints in a microwave to bring out more detail; playing with layers gives a spot more control. The cliff edge was lighted, but every once in a while the wind would catch the water and lift it like a veil, so I took almost a dozen shots. The camera delays a split second after I click the shutter, so there is luck and anticipation involved. As cynlee suggests, with a few extra takes, the odds are better that something will align just right. cynlee, Thank you for the comments and encouragement. I'll go back to these 3 and get at least 1 of them into the Gallery. It might still be possible to finesse something from #4, and the experience of playing with it will be good... but #2 is a special moment. We didn't get up the mist trail to Vernal and Nevada Falls which is perhaps a good thing: my images from the base of the lower Yosemite Falls are all water-beaded... so much spray at the bridge that it was almost like showering! Sometimes it is best to look for the intimate picture rather than the grand view, but feeling the rock vibrate under the water is an experience. :) Carolly
