From a few minutes ago:
This is in-camera black & white with a simulated yellow filter. Other than cropping it into a 5:4 format, I just raised the mids in a film-like contrast curve in RawTherapee5.8, that’s all. ISO1600 on the Olympus OM-D E-M10 together with Mitchie’s Panasonic Lumix 20mm/1.7 lens at f/4.
As always, thanks for viewing.
