Field notes
The guide tells users to keep original files and avoid sending them through messaging or social apps that may compress them. It treats ordinary photos as suitable for shutter and metadata checks, but requires distinct test images for sensor assessment. The page describes a simple price adjustment formula and explicitly separates that estimate from market valuation.
