1, Open both photos (your L and RGB) in photoshop.
2, Click on the L, ctrl A, ctrl c.
3, Click on the RGB, ctrol v.
4, you will see two layers on the RGB (you can close the L now); click on the top layer.
5, change blending mode to Luminosity.

That's it!
:wink:

thanks sn-10 :D
because I am using Qhy 9 to take LRGB
after I finish the shoots with LRGB filter I will have four photos which are B/W (am iI right??)
so how to set the B/W RGB to real RGB??
I think I am so stupid to do the photo process :( :(

搭單一句, RGB應該係用黑白相機+分別用紅綠藍filter拍成的照片, 但係請問L channel係乜東東呢? :oops:

I see. It's a bit tricky, you need to use "clipping masks"

Let try to summarize the procedure as follows:
1, Open all layers.
2, R is the base layer, paste G on top of R, and then B on top of G.
3, Close the G and B files.
4, Change the G and B layers to screen, keeping R to normal.
5, Go the R, change mode to RGB; then layer>new adjustment layer>hue/saturation
6, Click the clipping option, rename it to H/S R (or whatever name you want it for identification), then OK.
7, You will see the Hue/Saturation box pops up, select colorize, then enter the color values. For R channel, you can start with Hue:360 Sat:100 Lightness: -50.
8, OK.
9, Repeat 5-8 for G and B, except that the values for G and B are:
G: 120, 100, -20
B: 240, 100, -40
10, Flatten it.
11, Further tweaking the colors.
12, Paste the L on top of it for further processing.

Another way to do it is to re-mode all RGB at once separately, then extract one channel from each one to replace the original one to the other one. The principle is the same, however.

Hope that helps. :wink:

P.S. This is only my method, the accuracy is not ensured. I'm sure you can find other ways to do it from the internet.
