So it's this - and I will try to state it without any implicit bias...
You want to compare the image quality between two different cameras and their image sizes
are different, say, one is 18MP and the other is 24MP. Do you think that resampling the image,
either up or down to make them the same size, is a valid step in the comparison?
Obviously, you might want to start with as many variables set equal as you can, like the same scene,
same lighting, lens, and if possible, processing.
Also, mention anything else that you think would make a valid comparison.
For people who are newish to resampling, it is the process of using software to up- or down-scale
an image to make the pixel size the same as that of another image. Another description (loosely used)
is "interpolation", but to me that's just one method of resampling.
