After attaching a solar filter on a DSLR, what two settings should be adjusted for maximum suppression of light?
Answer
ISO to its base level and the fastest possible shutter speed.
The camera settings must complement the physical filtering by using the ISO at its lowest setting (often 100 or 200) and selecting the fastest available shutter speed (like 1/4000th of a second) to prevent sensor saturation and heat buildup.
