clip raster symbology changes

Discussion created by klipvis on Nov 18, 2010
Hi
I have an RGB composite raster of a side scan sonar mosaic. Because the study area has an irregular shape there is quite a large black border around the study area. I have tried to clip the raster to get rid of the black border but when I do this it changes the colour spectrum/symbology of the remaining data. How can I clip a raster without changing the appearance of the remaining data?

PS
Setting the black background as no data does not work either, as some of the actual data is also black, thus leaving holes in the data set.

Regards
Wilhelm
