I use Lr5.2 to adjust my RAW(NEF) files and paid attention that when opening them in LR they appears a lot darker than in the camera (D7100) or in ViewNX2 (Nikon). I'm curious to know if it is normal or if there is a problem with the pictures (wrong shooting settings)? Anyway, in most of the cases it's adjustable with the basic tools, except that for some darker pictures the adjustment give noise.
Thanks for enlighting my ignorance.
