>>2854282It was another anon who replied "lol", but yeah, lightroom surely isn't going to overcome the basic rules of mathematics. What if you turn up the contrast? It surely won't preserve all the details in the dark and bright areas upon exporting/saving to an 8-bit image file.
Rotating an image will -always- reduce the image qualiy unless you're rotating a multiple of 90°, and unless your camera has a non-cubic pixel order.
That usually does't matter too much as nearly all cameras with regular CMOS or CCD sensors produce blurry images at 100 % scale, due to interpolation to "gain" full colour information on all pixels. However my Sigma DP2 Merrill has a different type of sensor (three seperate 15 MP sensor layers) and takes near perfectly sharp images even at 100 % scaling, so that any quality loss becomes visible immediately.
This picture is a 100 % crop of an image. While I admit that the camera has tons of flaws, the image quality is beyond amazing.
