Yes I want to shoot with 200 ISO but I want smallest aperture 11, 16 or 22. :-)) Thanks,

Don’t shoot night at f22!! … and 3200 ISO will be so noisy it will be a waste of time!

3200 ISO @ f22 = 16 minutes
is the same as

200 ISO @ f4 = 8 minutes

That will give you the same exposure but less noise and half the time!

If we need f/22 with 3200 ISO and for that speed of film and aperture we need 16 min. exposure. Now if we use your table and change to ISO 100, the exposure time will be 80 min.

Keep the ISO the same and for each full aperture stop the shutter speed halves or doubles. And yes Freds computer chart explains the same thing but in more detail.. Aperture works the same.

I forget something. What if I want to change aperture?? How to calculate this? uupss! I forget something. What if I want to change aperture?? How to calculate this?

Thanks you! I finally find what I wont. And yes I need 20 sec. exposure at 1600 ISO :)) Very nice table. Sorry on my bad English grammar-Thanks! Yes!! Thanks you! I finally find what I wont.
