Taking photos at night dependent on moonlight, but I want to be able to do some of my work during daylight hours. I was thinking I could stack various filters on top of each other to mimic nighttime UV/VIS/IR ambient light equivalents of various moon stages even if it were daytime.



Suggestions?

10-stop Neutral Density filter?  Not sure exactly what you're trying to do.

If you are just looking to simulate the darkness, you can stack neutral density filters to reduce the light. A polarizer filter can help with that, too.

Will a polarizing filter in front of a neutral density filter allow me to vary the amount of light, or do I need to stack 2 polarizing filters?

I was thinking of stacking Neutral Density filters.

One thing I don't know is what value 2 x ND2 or 3 x ND2 filters will be equivalent to.

Are you looking to use a specific exposure?  Remember the more glass you put in front of a lens the more chances for something to go wrong.  

There should be charts on the filter websites that will calculate that stuff for you.

Just underexpose the shot by 3 or 4 stops, and it will be dark.   That's all night time is anyway.....a lack of light.

Do a search in Youtube and your question will be not just answered, but demonstrated.

It is all about flash photography in daylight.  Really helpful and very detailed.

Or get a variable: Tiffen 77mm Variable Neutral Density Filter.

very interesting.  "day for night" is pretty awesome now that I see what is happening.

2 stop ND or underexposure, WB shift to tungsten for the blue cast, and minor touchups as needed.
Some of those examples are pretty spectacular. It seems a lot more straightforward than I would have expected.

Gonna have to experiment with this a bit.
thanks for the point in the right direction.
