Greetings,
I have a question for you folks, I took this 8 minutes exposure with B&W ND 3.0 and stacked upon Kaesemann XS-Pro Circular Polarizer.
Now I want to stack another ND filter before the Pol to achieve >30 minutes exposures.
However, even the ND3.0 + Pol made it very difficult to see something through my viewfinder. After a while the eyes adjusted and I could make out the Pol. effect and adjust accordingly. But with an additional ND, I can see nuttin anymore and even autofocus will not work anymore in full sunlight on a bright day.
Am I correct to assume that I need to focus manually to infinity, pull back a wee bit perhaps, and do upfront calculations how long the exposure needs to be and then shoot "blind" so to speak?
Or is there another way?
Thanks
Georg
