For some time now I have been building and maintaining not only the biggest archive of Aurora observational data and realtime forecasting (The Aurora Forecast Service), but I have also been building a database of sensor profiles for long exposure / high ISO.
Recently I performed an update to the The Sensor Noise DB, allowing you to compare camera models more easily. I hope you find this update useful. I also plan to have the Nikon D5, Pentax K1 and Canon 1D mark II test shots available soon, so stay tuned.
I’d also like to thank Walch Optics for there support, and recommend them as your first point of call for photographic equipment in Hobart.
