Assembling an RGB photo from three grayscale tiffs

[Pax2You]

Can it be done? I'm doing astrophotography and need to assemble my r g and b data into their respective channels for a single RGB image. Can AP do this yet? Thanks for the help and I am enjoying the software!

As a followup to my own question, this seems to work as a way to combine into an rgb image. A little convoluted but it works

Edit-Edit: it does work but I had to output the Affinity tiff to png in AP (I had previously output both tiff to png from cs4 to run through the color stretch)

I combined the same three R, G, and B tiff files using ps cs4 and ap. I then converted the resulting two RGB files to png before putting them through the same color stretch via rnc color stretch.

Affinity

CS4

So the channel packing method is effective to combine the separate grayscale tiffs into their respective color channels of a single RGB image.

In AP it is possible to modify single channels but it is not simple process as you really do not know when operations are targeted to channel and when whole RGB layer. I have tried to map it out but with bad success.

AP really should make working with channels more direct.
