Hello,
I created an alpha channel with marquee tool on a colored backgound, by using "select > save selection", the alpha channel appeared at the bottom of the channel palette. I know the white part should represents transparency and the black part is opaque. But when I import this into the Adobe premiere6.5, the thing is reversed, I have to use "alpha channel" plus "reverse" option to get what I want - see through the "white" part. I heard there is an option in the photoshop with which you can define whether you want "white" is transparent,black is opaque or vice versa, is that true ? Or I missed something ? Thanks. |
