Good comparative analysis of the quality of jpeg exports from Lightroom
Jeffrey Friedl has taken the time to create a javascript powered tool that lets you compare jpeg images exported at different quality levels.
The Lightroom default JPEG export quality of 75, falling in the 70〜76 range, seems to provide for as good a visible result as the highest quality setting for all the samples except for the bridge, which seems to suffer at least slight posterization banding at all levels, including even “lossless TIFF”.
It’s a great read for all photographers, especially ones using Lightroom.
Shout out to Daring Fireball, where I found the story.
