 |
|
Hello all. I'm new to photoshop and I need to change the contrast of part of the picture and I cant manage to do it.
I've created a different layer with the piece of the picture I want to change the contrast to, but it doesnt work and it affects the whole picture. How do I do it?
Thank you. |

Hi mates90 welcome to the forum. A picture speaks a thousand words and all that.

mmm simple step is to duplicate the layer as many times as needed then apply a layer mask to each 1 adjust the whole layer as needed then paint in the selected parts you need

It may be a case of clipping the adjustment layer to the layer you want to affect (hover your cursor between the two layers until you see two circles b&w, or use the clip to layer icon)

If you have actually got the piece of picture in a new layer, then it should work. Things to check include:
- That the new layer is ABOVE the existing layer (not below)
- That the new layer is SELECTED when you do the adjustment (look at the layers panel, the layer should be blue if it's selected. If you can't see the layers panel then go to Window and make sure that "Layers" is ticked)
Test by making the various layers visible and not visible (use the eye on the left of the layer in the layers panel).
A couple more tips:
- if you add a feather when you do the selection then the change in contrast won't be so stark (when you select, go to select->modify->feather, try 30 to start with)
- you can change the opacity of the new layer if the effect is a little harsh (look at the top right of the layers panel - make sure the correct layer is selected).
Good luck! |

This haunted me for some time in the past until I found this method
An adjustment layer will affect ALL the layers under it if you do not do the following:
1) Check that the adjustment layer is on top of the layer you want to adjust
2) In the layers panel hover wit the mouse pointer over the line between both layers
3) Press ALT key
4) you should see two small circles on over the other
5) Click the left mouse button
What you have just done is made the adjustment layer only affect the layer below it.
I tried "print screen" to show you what the layers panel will look llike but pPhotoshop will not allow the two circles to appear in a print screen[/u] |
