So, without further ado...
Crop and resize your base to whatever you want.
Create a new Color Balance Layer
and drag the Yellow/Blue level all the way down to -100.
You picture should look like this now:
Next, duplicate the Color Balance Layer like this
if you don't have the Layers Palette displayed. Your picture should look like this:
Now, merge the three layers.
Duplicate the new merged layer as you did above, and set the duplicate to screen, like this if you have the Layers Palette displayed
or this if you don't.
Your picture should look like this:
Now, because I wanted the reds to stand out, I added a Channel Mixer layer,
and brought out the reds and then balanced them with green and blue until I got the result I wanted. The result was R(150) G(-35) B(-10).
Your picture should now look like this:
And finally, I added this texture made by domeofstars
by copyng it
pasting it to the picture of Rose
and setting it to screen as I did above.
I hope this helped. Let me know if you have any questions or suggestions for how I could make future tutorials better.
