I am no expert in QGIS and I've already spend quite some time to find an answer to this, but I could not.

Could anyone tell me how to change the elevation value of DEM?

The one I have has been created for a small area, done with drone footage, and it has for some reason values that lie approx. 30 meters lower than the elevation a.s.l. really is (according to reference maps).

After loading the DEM, you can use the Raster | Raster calculator menu option to modify values.

For example, here the raster 'Tsavo.dem' was loaded (it appears as band Tsavo@1), and the calculator will produce a new TIF called tsavoMinus30.tif using the calculation "Tsavo@1" - 30
