View Full Version : Shutter closes when sufficient light received
27-03-11, 09:47 AM
A good few years ago I had a friend who had a camera ( I think Olympus, unknown model ) which had a exposure method which when sufficient light had been received would close the shutter. He used it to great effect to capture fireworks bursting. Point the camera set the exposure method and when the firework went off the camera took the picture.
This worked, as I was told, by the metering watching the amount of light reflected from the film. (You remember those cameras that used film don't you.)
My question is there a method to do this with a digital camera?

Hi, I've not heard of that function on a digital camera. Perhaps others might?
As for shooting fireworks. Just getting one burst is not very exciting and you don't really want the rocket part showing.
Far better to open the shutter for say 60 seconds and hold a piece of black card in front of the lens.
As each burst takes place, remove the card for a few seconds, then replace.
This gives a much more interesting picture Example here... (http://www.trekearth.com/gallery/Europe/United_Kingdom/photo551541.htm) :)

Thanks for your input.
The exact application I have in mind is capturing in still images the New Year's celebrations on Madeira. If you haven't seen these you would not realise that blank card manipulation is not a practical way of proceeding. Obviously video would be but that is difficult to print. I could possibly video the display and then edit the results down to individual frames.
Thanks again, maybe other as you say may know the capabilities of digital cameras for this purpose.

Well, I wonder how this set of images were captured? Madeira New Year's Celebration 2011 (http://www.flickr.com/photos/madeiraarchipelago/5321004735/) :D

That is exactly my question.
As with all fireworks photos, and not to denigrate the owner of the copyright of those photos, they have missed the ultimate bursts in a number of shots. What I want to do is take a series of shots which will include the whole sequence from launch to final burst. I thought back to my friend who seemed to be able to do just that but had a specialised camera mode and wanted to repeat that with a digital camera.
So far no one else has responded to my question.

Okay, well do come back and let us know if you find out.
Sounds fascinating to me :D

I used to have an old Olympus OM2n, and I think that metered in a similar way. Haven't seen the same thing in Dslrs.
