Just for kicks, here is a simple image with a basic work flow applied in Lightroom. Some may find it interesting, others not. The things that are the strongest tools to me are the blue channel in camera calibration, helping to add that deeper colour and the use of selective contrast (blacker blacks/whiter whites) and the brush tool used gently and selectively instead of global sharpening.
The RAW file with no pre-set applied and cropping. Underexposed, flat and poorly framed, EM5 mk1, 25mm.
Basic import setting with cropping (-50 highlights, +25 whites, -30 black, +30 blue channel in camera calibration). This usually works pretty well on a well exposed file, but not a flatter one.
Added White instead of added exposure (+50 from +25)
Deepened blacks instead of contrast (-50 from -30)
Gentle Brush over the focus area (+20 contrast, +15 clarity and +15 sharpness). Sharpening is otherwise Lightroom standard (+25)
A little added vibrance, to see if it adds or detracts (+30). I can go either way with this one.
