Low shutter speed lag fix#88

Show a preview for a faster shutterspeed instead and simulate the actual exposure by boosting the preview images iso.

It doesn’t matter that the preview will be slightly different from the actual photo. It will be better than the lag time.

This is on our list of improvements, although we can’t share an ETA for it.

An additional UX improvement on this note could be to decouple the shutter speed setting from the display so that if the preview takes some time to catch up at least I know which setting I’ll be on when it catches up.

In addition to this it could suspend computation of the next frame in progress whenever the user makes a shutter speed change, or better yet wait a few milliseconds so that when the wheel is scrolled quickly only the last setting change is calculated and displayed.

These two improvements would be great overall for the user experience and might even be more important than the slow shutter taking a while to display. It would make the lower end of the speeds a lot more user friendly.
