I know it might be a little soon to ask, but I would love to see a series of monochrome images using the four mono profiles. I saw the DPR samples and the grain simulation is very interesting.
I've downloaded a few of DPR's OM-3 raw
samples and played with them in Workspace v2.4.
In raw processing, you can set the picture mode to Monotone or to Monochrome Profile, but I didn't find four different Mono profiles as such. So, I'm not 100% confident that this is fully representative of the in-camera effects (*).
When you pick Monochrome Profile, you can add a film grain effect with a Low, Medium or High setting. The Low setting is good for 1:1 viewing and the stronger settings should be good for prints (all three are much better than the much too contrastful 'grainy film' art filters from the old days, which are also still available).
The Monotone and Monochrome picture modes look nearly identical in Workspace. To judge the grain effects in the lower three samples, the image below should be viewed at its original size. The samples in it are crops from the .ORF file and have not been resized during or after processing.
*: As I understand it from the manual, the 4 Mono profiles are just different variations of the Monochrome picture mode, each with different sub-settings. By default, they're configured like this:
MONO1 - A standard (monochrome) preset. Each setting value is set to default (±0).
MONO2 - Creates a monochrome film-like finish.
MONO3 - Produces an infrared film-like effect.
MONO4 - Suppresses contrast for a softer look.
In the samples above, I only used the default Monochrome picture mode, with different settings (Off Low Medium High) for the film grain effect.
