I have two Hoya ND filters ND x 8 (3 stops) and ND x 400 (9 stops). If ND filter is ONLY use to stop down light, can we use exposure compensation to do so instead of these expensive filters?
Can’t we achieve long exposure by decreasing f stops in exposure compensation?
What’s the difference between the two?
1) F8, ISO 100, 15 sec exposure, ND x 8 (-3 stops)
2) F8, ISO 100, 15 sec exposure, exposure compensation -3 stops
What benefit will I have using ND filters instead of exposure compensation?
