"Meet The Fader, the weighted preset plugin for Lightroom 3! Instead of the boring static 100% presets, you can now dynamically choose how much of the preset you want to apply. And of course, The Fader goes up to 150%, so you can over-process your over processing! And if you REALLY hate cross-processing, you can have up to 50% less of it simply by moving the slider below 0%."

"Lightroom is designed to adjust pixels in a non-destructive way, and when you export, all your adjustments are compiled with the RAW sensor data to produce a standard RGB raster image. Photoshop, on the other hand, is designed to manipulate pixels by altering and moving pixels in a rendered image."

"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”."
