@Amadora
Wow you do miracles when pasting, stunning results to work without using layers....compliment
Back to your example of the moon
Say
Quote:
I have a picture of an ocean, I want to add a picture with a moon. If i open the picture with the ocean do I open another layer and layer it over the ocean picture? When I do that it makes it look like a picture on a picture. What do you mean by transperancy?
If I cut the moon out and past it onto the ocean picture then it creats exactly what I want. If I layer it then what good is that to me, I have to blend, erase, cover the things I don't want in the picture.
Please explain to me how a layer even works and why its better?
you find a perfect example:
Call ocean BG layer and the moon Image 2
case 1)
If the moon of image 2 has a not too dark sky
and "Bg" layer has a darker sky around the moon
then you just have to crop (just crop the a square )image 2 close to the moon
Paste on BG layer as new layer, move in place
Set layer mode on LIGHTEN ONLY and the miracle is done
Advantages...many, you may still edit, as move the moon in a better position, scale up or down the moon,
change moon color without risk to change color around
Case 2
We are not so lucky as example because the Sky around the moon is lighter of that in BG layer
so you have to select the moon (i say this to simplify in this video a much better method
(
viewtopic.php?f=10&t=2495 ) but even select and copy would work
Then if instead then paste on your image you paste over a new transparent layer on top you still have all the advanges of case 1
And more because often defect of cutting are noticed only too late...but if the moon is on a different layer that may be corrected (as example correcting the cut or slighly blurring the moon edges or both...)
I hope now you get the point
Moon was a perfect example allowed me to explain one of the miracles of layer modes
And lighten only has a oppsite DARKEN ONLY that allow the same miracle when you wish to add something more dark to a image :
No more need to make accurate selection copy paste...just move that new layer on layer on top, change mode in DARKEN ONLY and miracle is done
