downsampling doesnt make cleaner images, it randomly removes both noisy and good pixels from the photo.

There's nothing random about a good downsampling algorithm.

correct

but the placement of noisy pixels is random, so any downsampling removal of noise is in effect random. the point you are avoiding as well is that no algorithm can atm select just noise to remove, thus you lose detail in the process. i get the feeling you guys dont like my point bc it discredits you downsampling argument when people criticize the horribad noise of sony's 24mp sensors. as you can see here, the lowly k-01 puts them to shame http://www.dpreview.com/reviews/studio-compare#baseDir=%2Freviews_data&cameraDataSubdir=boxshot&indexFileName=boxshotindex.xml&presetsFileName=boxshotpresets.xml&showDescriptions=false&headerTitle=Studio%20scene&headerSubTitle=Standard%20studio%20scene%20comparison&masterCamera=pentax_k01&masterSample=imgp1376.acr&slotsCount=4&slot0Camera=pentax_k01&slot0Sample=imgp1376.acr&slot0DisableCameraSelection=true&slot0DisableSampleSelection=true&slot0LinkWithMaster=true&slot1Camera=sony_nex7&slot1Sample=dsc03033.acr&slot2Camera=sony_slta65&slot2Sample=dsc02913.acr&slot3Camera=sony_slta77&slot3Sample=dsc02820_2.acr&x=1.093912378461236&y=-0.1116582076746557
