i took a series of pictures yesterday and discovered that shooting around f/13, f/16, there is what appears to be a hair located on the image sensor and is visible in the pictures where the lens is stepped down. it appears as like a blurry translucent strand of spaghetti in the upper left corner of the pictures.
some of the photos the enigma is only present in the sky; other pictures it is present on a building with beautiful stained glass.
is there a tool in lightroom that magically fixes this for me? or can i somehow go pixel by pixel and fix the problem somehow?
