Alternate frames

[garry23]

Does any one know what time between frames is hard coded into dual-ISO alternate frame feature.

In other words, when does it reset, if at all.

I would welcome a user time setting, ie if next frame taken within x seconds it will be dual, else it will be normal.

And a switch to have the first frame normal and the second dual. This way, with the time window, you have more options.
