I'm not sure what you mean by this. Upsampling does not make the
noise more intense at any fixed spatial frequency of the original

Who is talking in that context?

I suggested that when you upsample a low-MP image to meet the
higher-MP one, its real image noise, relative to the higher one, is
now apparent, and no longer "hiding" by having a small displayed
image size.

John, have you even read his posts?...He has reached his opinion by comparing two different pics that he downloaded from some website that were'nt even exposed the same.

He then downsized the higher res 50D image to match the size of the lower res 40D image...That hides noise/reduces noise/gets rid of noise, whatever you want to call it, but the end result is totally irrelevant due to the flawed methodology used.

He then slags Phils 50D and 40D reviews off when they just happen to show his opinion to be incorrect.
