So Shanne gave me the challenge of using different methods of converting an image to black and white. and specifically to try it using a color image in which the colors all had similar tonal values.
So here you see firstly an image where orange, blue and green are similar in tone, i used the shadows/highlight slider to make sure the image was fairly even in tone to start with.
2nd image is purely using the desaturation setting, the 3rd is only slightly different using the grayscale conversion.
I thn used a couple of tutorials from photoshopessentials.com
Not only did you put a lot of work into all the technical aspects of creating these various b&w images, but also in the explanation of what you did. Very interesting, btw. (The last one is my fav of all the "recipes".)
that's worked really well - and yes, tbh, I would start decomposing to channels when I have a tonally similar shot and want to use the channels to bring out the contrasts - but it's a Get Pushed challenge and it's more worthwhile if you learn something
It's similar - it's the button to split the pictures into red, green and blue channels separately - which is what you show in your second row. I sometimes mix them by adding layer masks and different opacities.
@shannejw i was on the right track then, the channel mixer adjustment layer is easy for the mix-down , but i suppose layer masks would work if parts of the image needed a different blend
Great result
@Lsquared - this is what I was suggesting
