[Digikam-users] jpeg from DSLR workflow: to 16bit or not

[Leonardo Canducci]

jpegs from my nikon d50 have 8bit color depth (as any jpeg AFAIK) but
I read that if I plan to edit the histograhm with tools like levels or
curves I'd better use 16bit color depth to avoid posterization, even
when the source is 8bit. Is that true? What's the best way to handle
this tools minimizing quality/information loss when source is a 8bit
jpeg? Should I load the jpeg, then switch to 1bit, then edit (curves,
levels) and the export back to jpeg?

Thanks!
