Platinum has a very long, straight response curve, maintaining detail in deep shadows and far highlights alike.
1. If shooting film and scanning, use black-and-white film which you've processed in a compensating developer like D-23.
2. If shooting digitally, use RAW mode. If the scene is contrasty, bracket exposures and use a blended-exposure technique like

of your images. Dan Margulis' book "Professional Photoshop" has a good discussion of stealing contrast from unimportant parts of the image in order to give it to the important parts.

Hi
I am new to PS amd wondered if anyone can help me with trying to replicate a platinum effect in black and white photographs. Is it through toning - if so what might be a starting point - or is it around channels?
Equally, it might be something i haven't thought about
Any help much appreciated
