When it comes to processing our images, there are all kinds of weird and crazy techniques out there. This is an interesting Lightroom one from Pye Jirsa over at SLR Lounge, which he calls “Dark Mode”. It allows you to quickly and easily draw a distinction between the lit areas you want to highlight, and the shadowy areas, without sending them to pure black.
It’s an approach I’d not seen before. It essentially involves bringing the exposure way down, the blacks way up to bring back the shadow detail and then controlling your contrast with the highlights. Some thought needs to be put into the shooting technique for this to work, but it looks to be quite effective if this is the final look you’re going for.
