Editing Alpha in PhotoShop question

**jucano2** · 04-09-2012, 11:45 AM

I saw the "sticky" post of Jim Robinson , http://www.flightsim.com/vbfs/showth...a-in-PhotoShop, regarding editing alpha channel directly in photoshop and found it very easy tio understand.
But sometimes when i save the bmp , it didnt get included the alpha section.
What i could be doing wrong?

Thks.

Save it as a Targa, open the Targa in DXTBmp and convert it to an extended bitmap.

Alpha is a channel, not a layer.

How do you know that PS is not saving the Alpha when you Save As Targa?

I am confused, you say (if I understand correctly) that you are not given the option to save as a Targa in Photoshop, then say you opened it in DXTBmp.

How did you open the Targa in DXTBmp if you could not save it in Photoshop?
