[Qgis-user] Colour ramps - raster file extreme values

[Lester Anderson]

Hi all,

I was wondering if anyone has advice for dealing with raster files that
have a few small areas of extreme highs/lows (eg +200/-150), but the main
data are much smaller values (+/- 25)?

Using a linear colour scheme, the extremes make the main areas of interest
washed out to a great extent so the subtle features get lost. Couln't see
any obvious route in v2.6

A way to adjust the curves, like in image processing or a log scale would
be useful.

Cheers
Lester
