comment What can cause blurry and out of focus images on a Nikon D5300 in no flash mode?
@user1032613 yes but I bet the blur was completely linear, this blur has a definite curvature to it which would indicate either a) it took place over a much longer period of time, or b) the boat was moving about incredibly violently to create a change in direction within 0.00125 seconds (probably to the extent to which nobody would even be attempting to take a photograph)

comment What is the benefit of a wide-aperture lens if you stop it down?
I don't have time to dig out lens test and try and equate them between brands but there are plenty of 50mm f/1.4 lenses that aren't amazing at f/1.8 or f/2 and would easily be beaten by something like the Sony/Zeiss FE 55 f/1.8 or the Leica AA 50 f/2 wide open. Likewise many ultrafast lenses f/1 or f/0.95 aren't great one stop down compared to the best f/1.4 lenses.

comment Photography editing style and secret
There is indeed a secret setting hidden away on all cameras that instantly makes all your images look exactly like Elizabeth's (including the horses), but I'm not allowed to tell you what it is, you have to discover it for yourself.

comment Deciding between two lenses
@user1899082 that image was taken with a 12mm (ultra-ultra-wide) lens and then cropped to prevent converging verticals, you wont quite be able to get that dramatic a perspective using a 24mm, nor will you be able to have the building's edges parallel to the edge of the image.

comment How can slightly blurred photos be improved in post processing?
@clabacchio that's exactly what I say in the answer, the images demonstrate the theory, not the practice.

Never in the course of human history has the following phrase been uttered "man, I really wish I'd bought a cheaper tripod" ;)
