[Qgis-user] Generating black white from RGB landsat using Raster Map calculator?

[Chas Sheen]

I split the image into R, G, B
Worked out in QGIS wher the Raster map calculator is.
Run...several times
No result foud in Results Directory. It runs quickly then refreshes inputs
and logs to blanks.
I'm new to QGIS....so have probably left out something basic.
Any clues
