I do something similar in that I compose and focus with the filters on by simply maxing out the ISO. I then use a cell phone light meter and a cell phone long exposure app to determine the correct exposure time at ISO 100. This works with my camera (6D2) easily using a 10 stop plus CP filter. His method should save some time tho. In the future, I will use max ISO to compose and focus, then use ISO 6400 to determine actual exposure time.
Thanks for this video, it should be very useful.
Your welcome. I haven't tried this yet. I have two apps on my phone ND Timer and the NISI app that will give you the correct exposure time but it requires you to get the correct exposure settings with the filter off the camera. Being able to get an exposure time with the filters on is a nice option considering the risk of damaging the filters everytime you take them off, put them back on etc. My NISI filters aren't inexpensive.
