Histogram stretch for raster mosaic

Hi,

 

I'm working with a 4-band mosaic dataset and I want to use the histograms of the individual bands to improve the colour.

 

I load the image in ArcMap and go to the layer properties - Symbology tabbed page.

 

I can adjust the curves of the histograms but I see no difference in the image and when I go back into the histogram, my changes weren't saved.

 

When I try the Image Analysis window, all the options are disabled.

 

Can someone perhaps tell me why I can't save my changes to the histograms?

 

I can save histogram curve changes for individual raster image files.

 

Thanks

Hanlie
