For Brashley Photography’s Mid-week Monochrome, a harbinger of spring the plum blossom, in black and white. I guess the raindrops are also a harbinger of spring!
This image was taken with my Sony RX10M4: F2.4, 8.8mm, ISO 100, Shutter Speed 1/125s. I processed it in Raw Therapee, then cropped and resized it and added a vignette in the GIMP.
I used Raw Therapee to do the conversion to Black and White. Specifically, the Channel Mixer method in the Black and White tool under the Colors tab. The preset was Absolute ROYGCBPM. Applying a special effect to the magenta and sliding down the green gamma setting. For information about how to use that tool check out this post: Black and White Digital Photo Processing-Part 2: Using Raw Therapee.
Both Raw Therapee and the GIMP are open source software (free!).
