“Output Sharpening and Noise Reduction were not applied to exported images that were resized to less than 1/3 of the original image size.”
Is this a copy-paste mistake? This was supposed to be fixed in 5.2 release already:
“Bugs Corrected in Lightroom 5.2
Output Sharpening and Noise Reduction were not applied to exported images that were resized to less than 1/3 of the original image size.”

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
