ideal cameras, because there are a lot of factors that affect the final image
quality, and at some point camera and lens designers have to trade one factor
for another to achieve the optimal image quality, within the given design

subset of image editing operations specifically aimed at non-destructive raw
photo post-production and is primarily focused on improving a photographer's
