Fun with Frame Averaging Images
« on: June 27, 2019, 05:29:30 pm »

I thought I'd start a thread that honors the tradition of the prolific Fun with MF Images thread.

I think the availability of native/simple/fast/easy/gapless/in-camera/raw-file-creating Frame Averaging will completely revolutionize landscape and architectural photography. Because it's a new way of approaching exposure it's hard to know how to best use it, both technically and aesthetically. It raises questions like:
- what kinds of scenes does it work well in? When does it not?
- What per-frame shutter speeds are best in what situations?
- When is a normal long exposure a better option?

I'm hoping this thread can foster the kind of sharing and discussion that helps the community approach these questions and create an open resource for those looking to explore Frame Averaging in their work.

For an overview of frame averaging as implemented on the Phase One IQ4 see Phase One Frame Averaging. If other cameras add this kind of feature I encourage others familiar with those cameras to post relevant links/tutorials for those cameras as well.

I expect to contribute my own first images to this thread this weekend!

Start with an image of your own new Peterson release!

I managed to borrow an IQ4 with a very early prototype version of the frame averaging back in the middle of May for a weekend, and I have two examples I would like to share with you.
The first one I already published on 500px back then: https://500px.com/photo/306166855/ It contains 2 second long exposures, hence the capture can considered gapless.
The second one is here: https://ibb.co/KWmWyKp . The exposure time for that was 1/50, so there were gaps between the takes. I think in total it was around 100 frames captured for this.

Normal long exposure is better option for scenes where you would like to capture a single movement - let's say few seconds of shots, but your maximum viable exposure time without filter would be less than the readout time. For example this image: https://500px.com/photo/285017105/ is not possible.

And here is an 'old' experiment with the timelapse function of the XF with an IQ3: https://500px.com/photo/291485045.
