The final selection, NR (Noise Reduction)/Lens, reduces noise in RAW images beyond what the camera is capable of. Even if you used either High Speed Noise Reduction or Long Exposure Noise Reduction in the camera, residual noise may remain. This function further tempers the noise levels. The Lens function is for correcting peripheral light dropoff (vignetting) seen with some camera/lens combinations as well as chromatic aberration also possible with some lenses. Canon has included a list of cameras and lenses that this function may be used with in the instruction manual found on the second CD included with the camera. For all its depth, DPP is remarkably easy to use. I’m certain if you just jump in and play with it you’ll find it will do everything you’ve always wanted in RAW conversion software, and more.
