What is the purpose of these? It doesn't look representative to typical results?
The C1-23 version is underexposed for whatever default didn't match the shot. I don't have that issue when using C1. The second one is fine, but not sure about any sort of improvement if the C1 version were to be exposed properly. The third one is so horribly overcooked* that it looks like a cartoon, which certainly can also be tamed by settings?
*) I have a factory calibrated glossy screen, it certainly may look more acceptable on a mate display.
