Hi Colin,

It could be a combination of a few things including limitations in dynamic range, noise, insufficient exposure, too much JPEG or other compression/resizing, excessive undersampling and/or people just wanting to process for a darker background or trying to hold the core brightness lower to see more into the core. It would be hard tell without a back to back comparison controlled for some of the variables.

Best
