Hey Joe-

For those shooting with a camera that has an ISO setting of 6400, doing the math on high ISO test shots couldn’t be easier. 1 second at 6400=1 minute at ISO 100 for any aperture, so correspondingly, 10 seconds = 10 minutes, 3 seconds = 3 minutes, etc.

For Nikon shooters with a native 200 ISO, 1 second at 6400= 1 minute at 200 -1 stop on the aperture.

It’s great not to have to worry about equations and exposure equivalents in the field…

I rarely, if ever, use ICNR (mostly due to decrease of productivity and battery life). Even with ICNR enabled, there’s still issues of not getting bright enough star trails and sensor bloom. With shorter exposures that are intended to be stacked, I can open up the aperture more to get the shorter burn-in and still be exposed properly and the star trails are nice and bright. This technique I learned from you is my favorite!

Hey Basim – The question of when to use in-camera noise reduction comes up pretty often, so I thought I’d revisit this technique. Glad you found it useful!

I learned this technique from you a long time ago and I’ve shot some great photos with it. Thanks again for taking the time to share this technique. It’s really fun! And as for the TC-80N3 remove, its a lifesaver for night photography!
