ability to save a file with an alpha channel?

[safoster71]

Greetings,

 

I like the effort so far, but since most of my job involves making .tga or .tif files with an alpha channel - i have to wonder.  Is that possible with Photo?  I have yet to discover the trick.  I know its a beta, is this something that will eventually be possible?

 

thanks
