CAUTION - This is an OOC image that has not had its noise reduced

Ron Tolmie: The review concluded that the ZS20 images were a little noisy and appeared soft. However, it takes only a few keystrokes in post processing to make major improvements in the noise and image clarity. For cameras that have tiny sensors that should be a standard practice for any image for which you want to make large prints or do 100% screen viewing. Cameras that try to do such processing in the camera often produce comparatively poor results. The OOC camera comparisons may be valid if you only want quick snapshots but they may not be accurate, or even useful, if the objective is to produce high quality final images.

It is probably correct to observe that most camera purchasers do not do post processing but many, if not most, of DPR readers DO use such processing as needed. The reviews should take into account the needs of those who are picky about IQ.

Cameras differ on where the interface between internal and external processing is set. What I was trying to say was that the ZS20 appears to have set that interface at a point that leaves a little more room for some of the processing to be done externally. The reviewer concluded that the images were inferior in IQ but that conclusion may be incorrect if you look at the final prints.

The output from the sensor is not an image but rather a very long string of digital numbers that have to be processed to create the image that is to be printed or viewed. You can get a better result if some of the final processing steps are done in a computer rather than in the camera. Many cameras produce a RAW image that is only partly processed and depends on external processing to produce what you see on the screen. Others, like the ZS20, produce an image that allows the users to finish the job if they are picky about image quality.
