I tired to shoot some waterfalls on a very sunny day, and the pictures all came out too overexposed. I read that a neutral density filter will help with that by allowing you to keep the aperture open for longer periods of time.
I bought an ND4 filter, but i am wondering if that's enough. I see that there are also ND8 filters, and maybe i should get that instead (or in addition). I took some test shots with the ND4 and was very pleased how well the subject came out against a bring blue sky.
Can someone help me sort this out?
Thanks! |

ND.3 (exposure adjustment = 1 stop, reduces ISO 1/2)
ND.6 (exposure adjustment = 2 stops, reduces ISO 1/4)
ND.9 (exposure adjustment = 3 stops, reduces ISO 1/8)
ND 1.8 (exposure adjustment = approx. 6 stops, transmits 1% of light,)
ND 3.0 (exposure adjustment = 10 stops, transmits 0.1% of light)
ND 4.0 (exposure adjustment = 13-2/3 stops, transmits 0.01% of light)
ND 6.0 = (exposure adjustment = approx. 20 stops)
They are also stackable

Thank you for your detailed reply, i think i may have to go and buy a few more filter and play with stacking them.
If i stack it with a circular polarizer, does the order matter?
One more thing. I read that combining a circular polarizer with a linear polarizer gives you a similar effect and allows for variance, but when i tried it, i really hated the lack of control i had. I was able to get the picture to go very dark but i didn't like having little control. I had no idea how to figure out what settings to use.
Does anyone here have experience with stacking two polarizers?
