Strange histogram issue

[Walter Schulz]

Hello!

Maybe someone is able to explain this behavior: Played around with some photos in LR (very pleasant and warm autumn day and a even better sunset) and the histogram seems to act rather odd. Everything looks quite normal reducing exposure (german: Belichtung). The "hill" slides gently to the left and the "peak" keeps its height ... until ... I cross a border and the "hill" losing half its height. Reducing exposure any further doesn't seem to affect the height. It keeps the reduced level..

LR 3.5 (64 bit)
Windows 7 Ultimate (64 bit)

TIA

Ciao, Walter

Hi Walter, this is normal. Lr is just rescaling the vertical axis (up-down distance) of the histogram because there are many values bunched up on the right side (clipped or near-clipped values).
