    Default App to lock focus and exposure when videoing? Nexus 7 (2013)

    I've found apps which do this for photos but none, yet, for videos. Recommendations?

    Unless you are using a tripod and focused on a fixed object, I can't think of why anyone would want this. That may be why you have not found any apps yet. Not enough general interest.

    The reason being that the auto focus hunts back and forth, particularly when an object-car or person-crosses horizontally. Secondly, when you tilt up at a building and the sky comes into shot, the exposure reduces causing the buildings or foreground objects to become silhouettes. Finally, there are all sorts of creative possibilities which are restricted by the lack of these features.

    If it's good enough for photo then it's good enough for video.

    Not saying you don't have a good reason for it, just not sure a lot of other people have a need. Maybe find a couple of video apps you otherwise like and then email the developer and suggest some enhancements? Even offer to beta test? Can't hurt.

    I was going to ask a similar question - but about locking focus and exposure when taking a photo. I haven't really taken any "great" photos yet with my Nexus 7, as compared with my iPhone 5. Usually it's because of some interfering lighting.

    On my iPhone I can long touch and it will focus/exposure lock. Then I can get the kind of nice exposure I want. But that doesn't seem to happen on my Nexus 7. Is there a way to do that?

    Also, the photos seem much noisier than my iPhone 5, even though both front cameras are 5 megapixels. I guess the lens quality of the Nexus 7 isn't great?

    Any thoughts?

    Perfect Shot-V5 does what you need. I came across it when looking to solve my problem. The LITE (free) version is fully functional but only for images of about 2mp. The paid version allows larger resolutions. However it only works with photos.

    That rings a bell because I liked what I saw on the lite version so bought the full version. However on my first three attempts at using it, after taking a pic, the prog shut down. So I got a refund. I thought it was just a problem with me. However as many months have elapsed since you tried it, this suggests that it may still be a buggy app.

    Yes, I want an exposure lock as well for the light background dark foreground issue too. I hate having to put my back to the sun or light source to get a clear photo subject.
    One question - Does the rear cam. use the light sensor facing me to do exposure calculations? If so, how is that supposed to auto adjust for the subject if the sensor isn't looking at the subject?

    The REAR camera of the Nexus 7 is 5 MP, but the FRONT camera is just 1.2 MP.

    Right. I was trying photos with the rear camera. They are quite noisy.
