nizo 800 night time lapse

[Justin Lovell]

Does anyone have any experience with shooting time lapse at night with the Shutter kept held open?

ie, which settings will give you the best exposure before overexposing the image?

just curious... 'cause i'm going to do some tests tonight..

p.s. from my experience, shooting at the 6fps interval with the shutter held open works great. Lets in waay more light than keeping the shutter at it's 150degree opening (normal) and in fact, It actually helps out to smooth the motion by creating a slight motion blur.

--i thought it would blur the image too much from me walking with the camera, but it actually ..to me... looks far better than the 'strobier' 6fps interval with a 150deg shutter.

coolest thing is that you don't need nearly as much light when you keep the shutter open. gain i'd say at least 2 1/2 stops.

if you use the auto b function, the shutter will only open long enough as needed (up to one full minute). that way if things suddenly get too bright it wont overexpose, and vice versa.
i pointed my nizo out my window once at night towards a busy street, it took quite a long time to get only a few seconds of film, but i was amazed at what came out.... streaks of headlights flowing across the screen.........beautiful...

Unfortunatly, the 800 doesn't have the "auto B" function, that feature is only found on the XX1 models as far as I know. I've never tried this with an 800 I'm afraid, sold that one as I prefer the auto option! I'm not sure how much the iris comes into play with the XX1's, but the times varied from about 0.5spf to 10spf in my experience of street-light shoots.
Have a play and note the times as you might find some cool effects! Its not such an obvoius thing long exposure as you will get into reciprocity failure at over about half a second anyhow, so to calculate it you would need the table of correction factors for the emulsion you are using.
Have fun!

Keep shooting the "reel" stuff!
