Hi Poom,

I see that does not work with raster calculator, but if you employ the plugin processing (within GDAL / OGR) you'll get the result.

regards,

Hi,
  I have installed QGIS 2.8.1.
OS: Windows 7

I am trying to use the "Raster Calculator" for calculating the expression log10("image.tiff"). But I get a message saying "Expression invalid". log and ln for the same expression are working fine. I need log to the base 10.

Please help me.
Thank you,
Poom.
