I'm trying to create a targa file with alpha channels in it. For some reason photoshop 7 is not saving the transparency. Any suggestions? Any tutorials.... Thanks

I tried it. When you have an alpha channel (not just transparancy, but an actual alpha channel made or duplicated from the 'transparancy of layer X' channel), the checkbox is selected to save them with a targa file. ONLY with 32 bits/pixel one or more alphachannel actually get saved. Good luck!

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,
:)

well if your image is flatened I don't think you can make a a part of it trans-parent.. it all boils down to layers. the eraser or selection mask will help you - Duplicate the BackGround layer - and trash the original.. your new "BackGround copy" can now be slightly erased to your desired requirements just grab an old image you like and use either a mask just make a selecion and when you are happy with it go to the Chanel and view the mask chan only and perhaps adjust the - when you find out wich way is the right way you can basicly Coose the level of transparency in the particular area you masked... exit the mask and DELETE it go a head n make a new layer and fill it white ( or something ) put it under the "layer copy to see the effect. or use an eraser @ 40% ( for example ) and -> try not go over a part of the image twice with the eraser <-

Double clicking on the background layer is an easy alternative for duplicating and trashing. It will be named 'Layer 0' by default if you click 'okay'.
