Hi,

When I display the histogram with gimp-2.0-pre, I got about nothing for many pictures when in linear mode.

With Gimp 1.2, the histogram was (is) displayed normally (at least I can see something) with the same pictures.

Do I miss something in the histogram behaviour or is there something special with linear/log modes ?

In linear mode you'll normally have a couple of peaks drowning out everything else.

I have not notices anythign particular. Maybe they are some spikes at the same position as the vertical axis.

Linear mode is the default (several people requested this). You can change this in the tool options, though.

Ok, I will use log scale, it is not a problem.

Cheers,
Dave.

For these pictures, you will want to use logarithmic mode. Linear works very well for photographic images but can be pretty much useless
for other images. But then, the histogram tool is mainly used with photographic images, so it makes sense to have linear scale as the default.

These are pictures from a digital SLR camera. I'm using the histogram together with the levels and curves colour-tools.

Ok, I will use the log scale. I have just notice it looks far different from the one in 1.2.
