Producing RGB and alpha channels like an existing file (attached)
Hi. I’m attaching two PSD files to show what I mean. I want rose.psd to become like tunnel.psd, which has 5 channels including an alpha channel. How do I go about this?
And if that would save time, is there a video somewhere that I can watch to help me do this? I looked for some reference material on Photoshop channels, but it did not help me understand how tunnel.psd was produced, or how to re-produce the same look in a new file.
Thanks to anyone taking the time to help and share tips.

1) click (mac: ctrl->command key) on the rose layer thumbnails. This loads the transparency as a selection.
2) switch to the channels palette
3) click on the second icon from the left at the bottom of the channel palette. This saves the selection as a channel.4a) (optional) to generate a black background, to deselect the active selection, and switch back to the layer palette.
4b) Add a solid color layer (fourth button from the left bottom of layer palette)
4c) drag this layer to the bottom underneath the rose layer
4e) right-mouse click the rose layer (NOT the thumbnail) and choose “Flatten image”.That’s it: you now have the same setup as the other image.

Thank you very, very much for your explanation, Herbert. Much appreciated.
I’m a bit new to channels in Photoshop, especially Alpha channels, so will take my time to figure this with your guidelines as soon as I have time, and hopefully will have no further questions. =)
Thank you again.
