I hope someone finds this as interesting as I do 🙂 I’m giving away state secrets here…
I mentioned before how you can stretch the range of info in B+W tremendously by using the colour channels.
Here is an example, using Jessica who was in an acting workshop last week.
On the left are the B+W images, and on the right, the original coloured ones, some quite dramatic.

The 1st image is a straight de-sat job.











The 2nd Image had the reds and green suppressed and the blues pushed. You can see the result in her darker eyes, but lighter lips. A more moody 60’s look.









The 3rd image has had the reverse done. Look how great her eyes look – the eyelashes stand out, the pupils are bright, and the lips have a nice contrast line in the middle. Jolly good.
