I got the breakthrough ND 4X 10-stop square filter. In testing it today, I set my camera to manual, got a reading from the the D4 and the used ND timmer on my phone to calculate the new shutter.

Does anyone use that app? It seems to be off a bit. I had to add more time to get a correct exposure, about 1/2 to 1 full stop. Am I doing something incorrectly? I used matrix metering.

Thanks, Dennis.

10x ND are rarely exactly 10 stops.

I counted manually while using my Firecrest 10x ND, worked pretty well. I little trial and error but I got it down.

Just gave my Hoya 10 stop a serious test last Sunday.  I used Photo Pills to calculate, but that resulted in a seriously over-exposed image.  I got better results when I used By Guess and By Golly.   Chalking that one up to user error.  :wub: Oh well....   :rolleyes:

I have Photo pills. It seems that sparky is right. The calculators are reporting a -10 correctly, math wise.
