So, I spent quite a bit of time talking about each filter, one at a time. But that is not all to life! I have two combos that I like to use, because sometimes I am up for a touch more then what one filter has to offer. The two combos I use are:
B+W ND106 + Tiffen ND8 = A total of 9 stops of light
B+W ND110 + Tiffen ND8 = A total of 13 stops of light.
So, why would I want to go through the trouble of stacking two filters to get 9 stops instead of using my 10 stop? Because some times, I do not want to spend time in the post processing phase for the color correction that I often times find my self doing with the B+W ND110. Now, the ND110 does alter the color tones, it makes the image warmer. It really is not a huge deal, but it can make a difference. And believe it or not, 10 stop is a big deal compared to 9 stops. I can push the 10 stops past 30 seconds, easily. If I make the aperture really small, I can get 40 or more seconds and still not be over exposed. But with the 9 stops, 30 seconds really is my max. Clouds out and covering the sun can extend that, a bit.
So, once again, why would I want to make 13 stops by stacking the two filters over just sticking with the 10 stops of the ND110? Because with 13 stops at my fingertips, I can really push it! In the sun, a 2 minute exposure is still VERY easy! And with a 2 minute day time exposure, a regular beach location can look like a place out of this world! For example, the image above is a 60 second exposure taken with the B+W ND110 and the Tiffen ND8. Middle of the day! The great thing about this 1 minute exposure is that the aperture is f/11. With any other filter or combo of filter, that would not be possible with out going to f/22 or smaller! And keeping it at f/11 is important to me, so the filters are perfect in play. I use to shoot these type of images at f/22 just to get the longer exposure, thanks to filters, never again! :) Ok, perhaps on occasion!
I hope you enjoy the image and I sure do hope you have a chance to check out my flicker account. I have a lot more photos there! :)
