As of now, most photographers have heard of these 10-stop ND filter. I was curious myself about this type of filter. There are few different brands available at this time that are most popular, the B+W ND3.0, the Lee Big-stopper and the Hitech ND 10 Pro-stop. I’m writing only on this Hitech version since I only have experience with this one. I also got the ND-8 version to use. The image that you see here in this blog is basically a panorama created using the ND-10 at sunrise, at Gallatin Range, a lesser known area that was fantastically beautiful, and, I found it by chance when driving up North to see some other attractions inside Yellowstone NP. One thing about this ND-10 is that it would impart a very dark blueish tint to your images and on the first look, per-processing, and you’d be discouraged. Also depending on how much light you have, you’d need to expose for a long period of time. However, if the condition and the mood is right, the picture can be very distinctive and beautiful and usually is hard to duplicate without this filter. So my take is, YES, it is worth it to have this filter in my bag. Another thing that is also great with this filter is that your black and white photos might be beautiful too, especially, when you take some photos of scenes in the middle of the day with very hash sun against some dark foreground like waterfalls, rivers, etc…, and it would not be easy without it.
To summarize how to use this filter:
Compare the the ND-8 filter, I think I used this one more frequently, because you CAN actually see thru it and therefore you can focus and meter your exposure without having to take the filter off, like in the ND-10 situation. However, you should know that with the ND-10, when the condition is right, it might give you magical results. The same tips that I give you on the ND-10 can be applied to this.
The pouch that comes with these Pro filters are well built and is a more welcome addition compared to the almost-unusable-plastic sleeves that come with the regular version.
The bottom line is this, I would recommend that if you have a chance, get these filters from one of these guys (either Hi-tech, Lee, or B+W), it is good to have them in your camera bags, because you don’t know when you need to use them and when you use them, the results could be awesome.
Hope that this help. Let me know if you have questions, I will be glad to answer them.
