your camera, the better the results will be, but in any case if you look
carefully at shots taken even by the most expensive cameras equipped with the
most expensive lenses you will see various artifacts.  It is very hard to make
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
restrictions and budget.  But we all want ideal shots, don't we?  So that's
what's Lensfun is all about: rectifying the defects introduced by your
photographic equipment.")

subset of image editing operations specifically aimed at non-destructive raw
photo post-production and is primarily focused on improving a photographer's
workflow by facilitating the handling of large numbers of images.  Most raw
formats are supported, including Pentax Pixel Shift, Canon Dual-Pixel, and those
from Foveon and X-Trans sensors.")
