Hi,
I did some experimenting with this (I too don't want to abandon LR) and found that this LR recipe reproduce the perceived sharpness in C1 almost exacly for a range of motifs in raw files from X-E4:
Enhance:
- Denoise' 40
- Raw Details
Preset:
Basic:
- Contrast +10
- Presence
- Texture +10
- Clarity +10
- Dehaze +10
Detail:
- Sharpening 110
- Radius 1
- Detail 10
- Masking 25
However, C1 (and DXO Pure Raw) renders e.g. blue sky differently (lighter than LR), and needs to be dealth with separately to achieve the C1 look.
