391 euro for a piece of software seems kinda crazy.

That's less than €1/hour for how much time I've spent using Capture One.

Good, ergonomic, efficient tools are worth their weight in gold. C1 is one of them. Importing/triage, editing, color profiles, tethered shooting - it's an incredibly powerful suite and works well.

For particularly problematic noisy/dark shots I'll do manual editing in DXO, but I do everything else in C1.
