I believe that would be a "feature". Mouse-wheel scrolling on the histogram is rather a "rough" tuning. Precise/finer tuning can be accomplished using the levels module. afaik, it has been this way for several years, maybe forever. -- (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri http://en.opensuse.org openSUSE Community Member facebook/ptilopteri http://wahoo.no-ip.org Photo Album: http://wahoo.no-ip.org/gallery2 Registered Linux User #207535 @ http://linuxcounter.net ___________________________________________________________________________ darktable developer mailing list to unsubscribe send a mail to [email protected]
