Recently i just bought this 2 filter but still not sure how to get the right exposure.
For example ND 0.9 filter, let said without this filter, the right exposure are
ISO 100 F11 and Shutter 1/30
If i put the ND 0.9 filter, ISO and Apperture remain the same, what is the right shutter speed ?
how to calculate to get the right shutter speed ?
For now, i just guessing to get the right shutter speed.
Any pro please teach and explain.
Thanks in advance
