i've been using Harald's formula for sometime now, in comparison with my version of Pyrocat-HD (+Vit C & some added organic restrainer).
My comment is per following:
- Beutler Pyro can yield extremely high-acutance, perhaps due to edge effect
- It's very energetic & often stretch the midtone contrast curve (which is great for dull days with flatter scenes)
- It's slightly foggy. I tried cutting back on the ATC (half the indicated amount) & that seems to cut down on fog.
Attached is a picture. Not artistically nice, but demonstrates the resolving power & acutance that can be achieved.
I'm pretty impressed. Now I only use those 2 devs. modded Pyrocat when i need to save my highlights & Beutler-Pyro when i want some midtone drama
