long exposure will make a difference (for canons that the in-camera black frame subtraction, which also affects raw). it will definitely be a good idea to do both measurements (that on and off) and maybe even with a couple of different exposure times. this kind of noise (gaussian part) should mainly be visible for long exposures, which is also where the black fram subtraction kicks in most. i don't expect the poissonian part to change much though. cheers, jo > When the sun is out tomorrow I will take photos with different camera noise > reduction settings and see what the result is.
