For taking full manual control of your camera settings, Camera FV-5 and Manual Camera are the best apps I've used. Camera FV-5 offers many advanced features such as an intervalometer, assignment of volume keys and manual focus, with design elements that aim to remind you of a DSLR.
Features (from Google Play)
- DSLR-like viewfinder display: see exposure time, aperture and stops display with EV and bracketing settings, in real-time.
- Full fledged exposure bracketing: from 3 to 7 frames, unlimited stops spacing, plus custom EV shifting.
- Built-in intervalometer: timelapses (even bracketed/HDR timelapses) and time-controlled picture series.
- Program and Speed-priority modes.
- Long exposure support: night photos and light trails with long exposure times up to 30 seconds.
- JPEG, true 16-bit RAW in DNG format, and lossless PNG photo capturing formats, perfect for post-processing.
- Manual shutter speed: from 1/80000 to 2", or the range available on your device*.
- All camera functions assignable to volume keys. You can adjust EV, ISO, color temperature and more using volume keys. Devices with hardware camera shutter key are also supported.
- EXIF and XMP sidecar metadata support.
- Autofocus, macro, touch-to-focus, true manual focus and infinity focus modes. Autofocus lock feature (AF-L).
- Autoexposure (AE-L) and auto white balance (AWB-L) locks in Android 4.0+.
- In background photo and RAW developing and processing allows a smooth, uninterrupted camera operation.
- Digital zoom using multi-touch pinch gesture. Also shows 35mm equivalent focal length!
- Live RGB histogram, 10 composition grid overlays and 9 crop guides available.
- Powerful organization options: different storage locations and fully customizable file names (even with variables).
Camera FV-5 is a great app but isn't my default camera app. I love the control and flexibility it offers, but I'd like to have exposure changes reflected in the view. Perhaps the aim is to replicate the viewfinder of a DSLR, but with electronic viewfinders already widespread in mirrorless cameras I'd prefer to have that additional function available.
