Hi David, rasters come in a few different flavours. RGB/greyscale photographic type images such as an aerial photograph or a georeferenced scan of a map are one. There's not a lot of point exporting those as text.
There are also Raster images where the RGB / black bands represent a frequency or attribute from a satellite or remote sensing instrument, you might want to convert those to a different format to use in a different package or just select a single band to work on. Single band raster such as grids or DEMS are another type of raster. The last 2 types above can be saved in alternate formats under the "convert format" option in the raster dropdown options somewhere, can't remember the exact name. I usually do this with grids / single band rasters. the command line option is gdaltranslate. "save as" doesn't work the same way it does as with vector data. I don't have QGIS open at the so I can't recommend a format but I think CSV is one of them.
