astrophotographer writes open letter to sony over 'star eater' nr


one of ian norman's examples of an image that would be affected by the 'star eater' noise reduction filtering. astrophotographer ian norman from website lonely speck has written an open letter to sony over its use of spacial filtering that can obliterate small stars in long exposure photos. the phenomenon has been identified on the dpreview forum and characterized by contributors including jim kasson. rather than just the usual long-exposure noise reduction (which takes a second, 'dark frame' exposure to identify hot pixels), sony's pre-raw processing applies a level of 'spacial filtering' to images shot for over 4 seconds. this can mis-identify small stars as faulty pixels and process them out before the raw file is written. norman says he no longer recommends the use of sony cam






analysis: the sony a7r iii is still a star eater


we sent some files to our friend jim kasson for analysis, and he confirms that the sony a7r iii is definitely still a star eater, despite several claims to the contrary that have been published online over the past week. looking at kasson's graphs, one can clearly see the noise reduction kick in near nyquist in kasson's energy plots. indeed, in our own shots of the stars with the a7r iii and latest a7r ii (firmware v3.00 and above), our final files only show stars that are larger than one pixel with a few neighboring pixels: suggesting that smaller stars are indeed 'eaten' or dimmed due to a spatial filtering algorithm. at a 3.2-second exposure, the 'spacial filtering' (star eater) is very mild, and won't affect your stars. but as soon as you hit 4-seconds, spacial fi
