Limits to ISO, Shutter Speed

Feature Request

I’ve been thinking why apps have not done a simple thing yet, or even why professional cameras don’t have this yet:

Could you implement a shutter speed and ISO limiter on both low and high ends?

As an example with video, I prefer sometimes just using auto ISO but want the shutter to have a minimum limit to how low it can go, such as 1/60 at 30p, or 1/125 at 60p.

I would imagine that it wouldn’t be too hard to create this, but I’m not a developer by any means. Hopefully you can do something like this! Glad to see that feedback is also listened to! Great app!

    Pro Camera has this ability (partially) if you use the shutter priority (S) or ISO priority (I) modes. Are you asking for simultaneous limits on shutter and ISO in full auto (A) mode then?

    It’s a bit more complicated than you’d think to make this smooth with the way the iOS camera works.

      Sort of? I shouldn’t have been as a blunt as I was.

      This would not be something like the (I) or (A) mode, but instead be a setting you could turn on for auto exposure to limit the shutter speed to your preferred setting.

      Let’s take an example from earlier, as if I wanted to shoot in 30p. If I wanted the minimum shutter speed to be 1/60, the camera would lock the shutter speed to 1/60 as long as it does not over expose the image . However, when the phone notices that the image is over exposed, only then will the shutter speed be increased to something quicker (1/125, 1/160, etc.) to compensate for the over exposure, allowing for the image to stay properly exposed.

      Something like that be possible, or is the iPhones processing not able to allow that?

        Understood - we’re mostly talking about the same thing. It’s a possibility! I will make this request public.

        You might be interested in reading about how the “program line” works in traditional cameras. The default AE engine on iOS actually does something similar to your suggestion by default, but it isn’t customizable obviously.
