Camera app that detects/prevents over-exposure?

    Bit of an odd one maybe but I'm driven nuts by the amount of photos I take with my Android phone that turn out to be over-exposed (pure 'white' in places). I've tried some popular alternative camera apps but none of them seem to address this basic problem. I know you can often manually adjust the exposure yourself but what I'm looking for is a camera app that auto-adjusts it BUT, and most importantly, does a good job at this!

    What metering options are there in your camera app? Do you have an example?

    Phone is not the best, a Huawei, but I'm fairly certain this is an app issue. Standard app controls seem limited to auto expose and +/-1,2,3 manual adjustments. Can't understand why an app can't check for saturation (any pixels with brightness value of 255) and adjust exposure down if necessary?

    It's metering. The software will look at a set area and adjust the exposure to give a balanced level in that area. Some spots can be blown out very easily, if the scene or metering area has a lot of contrast.

    Right, I think I get it - the issue so is that the apps I've tried aren't metering off the entire image. I find that often when you force metering off the brightest part of the image you then end up with the opposite problem - an underexposed image. So... does anyone know of an Android camera app that has a multi-spot metering option like you get with digital cameras?

    They probably are, and that's the problem. The blown out spots aren't big enough to affect the overall exposure.
