New Type of Rack focus effect
« on: August 06, 2012, 06:56:54 AM »
Would it be able to run a script that would-
A.) Change the Aperture one stop at a time over 2 seconds or so
And
B.) Change the ISO or Shutter to compensate for the exposure change.

The effect would be a rack focus of the depth of field while maintaining the same exposure.

Example of use
You could have thin focus on someone's face with a blurry background, a new person walks into frame and then you could have them both in focus by stepping down.

haha a Bokeh Pull! Cool. Isn't that just an iris change with auto ISO on?

I'm almost sure there are older versions of ML with this feature enabled, probably one year old or more.

I don't think that would be useable for video. Too many button presses on an electric lens and there would be lag. I'm talking about changing the ISO or Shutter speed at the exact same time as the Iris changes so there would be no visual brightness change
