Severe banding in Lightroom 4 (Mac)
« on: September 22, 2013, 08:55:57 pm »

I am seeing severe banding in dark sky areas when viewing and editing photos in Lightroom 4 on my Macbook Air. It's always visible in the library module, and usually in the develop module as well. Not always. It appears when I export sometimes, not always.

Any ideas on how to fix this?

Develop should present the shot in it's full glory, so posterization in Develop module could mean a severely compressed image or issue with the display profile.
Library previews are compressed JPGs, so if you set a lower quality for previews you may encounter posterization effects.

The question is, is this banding a result of the display or in the document? I suspect the later if you're dealing with raw data. That's an issue with poor(er) quality display systems that don't produce anything close to 8-bits per color let alone more than that. Always examine this in Develop at 1:1 or greater too. You can't properly evaluate this kind of data quality in the other modules, they use a different preview quality and architecture.

The few times i experienced such banding in LR was always the display the cause. In one case when also having the option to display the image on an iPad coming from a macbook (Airdisplay or something like that), in another case due to a bad display profile.
