Multiple exposures on IQ3-100?

Postby Rogerxnz » Sun Apr 22, 2018 11:18 pm

That’s my question: can you do multiple exposures on the same frame/file in camera on an IQ3-100?

On further reflection, the question should really be: is there any camera which allows multiple exposures with an IQ3-100 on a single frame/file?

This could be done on a technical camera. Enable the electronic shutter and set the exposure time on the back to as long as needed (30s, 1 minute etc.). Make sure there is no cable between the back and the lens Start the exposure on the back, then pop the shutter as many times as needed.

Thank you for that, Jon.

If I wanted to re-compose an image as part of the multiple exposures, I would set the exposure time on the back to, say, 60 mins and then just fire the shutter on the lens for the “real” exposures as many times as I needed to get a sufficient exposure.

But, how would i recompose (that is, use the viewfinder) between the real exposures?

There is not really a way to do that in camera because you have to end each shot.. in that sense it is better to combine the files together later in Photoshop.
