Hi DhamonGrimwulf, welcome to the forum,

One of the best way to make a part of your picture transparent is to use a mask. This method is "non-destructive" (meaning NO pixel are injured in the process ;)) and gives you the flexibility to change your mind.

If you do a search on the forum for the topic "transparency" you should find a few helpful threads.

If you have a specific example you want us to help you with, please, by all means, post it to a thread and we'll take a look.

hope to see you around,
:)
