Sky replacement

[Linda mccormick]

I am trying to replace the sky in a photo with one that has some interest.  According to the tutorial one selects the selection brush tool and increases brush width. Then make selection of the sky, wiggle it about and as the lecturer says “there pretty much done it for us”.  I beg to differ!  No dotted lines outlining the sky area, no nothing.  So what little trick did he do that the lecturer assumes we know.  

Linda, real novice

Hello Linda,

I think, you must set  the selection brush to add.

1. Try using the Flood select tool 
2. Uncheck the contiguous box, this allows the selection tool to select area's that are not connected.
3. Pick a bit of the sky and slowly pull over it until all of the sky is selected
   • Note: If parts of the image that you don't want selecting start to be selected move the cursor back a bit until they get deselected
4. Refine the selection with a small amount of feathering something like 0.2 - 0.3px
5. Hit delete to see the result.
6. Save the selection using Select > Save Selection > As spare channel
   • Note: You can load the selection from the Channel panel
7. Drag a sky in and place it behind the tree layer to see if the selection worked
8. You might have to load the selection back in and do a bit of erasing.
