OK, here is a quick and easy mono conversion that will give the ability to adjust the tonal response without getting into channel mixer. I hammered it out in CS, so it should play in CS and above. I also suspect it is OK in PS7 as well.
Just to clarify, I DID NOT "write" this action in the sense of thinking up how it works. I read this method of mono conversion on some long forgotten Photoshop site years ago. If anyone knows where I read it, or who originally wrote it, speak up, as I will gladly give credit.
But when I used the technique the first time, I thought it would make a for a pretty cool "quick and dirty" conversion, and still retain a good deal of control, so I typed it up as an action and have been using it for a long time. One of the things that I like about it, is that it does not alter the global intensity - unlike channel mixer - you don't have to keep three sliders in balance to maintain brightness.
When you run the action, you will end up with two adjustment layers. One says "Use Other" - if that is not self evident, then nothing can help you.
The other says "Adjust Hue" - so you don't have to cipher out what this means:
Then just double click HERE:
| MIME changed to 'text/html' | Content warning: data |
And that will bring up the adjustment window. Move the Hue slider back and forth and see the changes as you do so.
When you are happy, flatten and save.
