AbtoCamera

The idea is marvelous, although as some else reviewed, changing the settings (some various ones) will crash the app. That's no good. But I think this app could mature quickly and be a great camera app for those of us who enjoy a variety of functions for photography. Don't bother with this app if you are simply a "point and shoot" photographer! I give 3 stars for now. Will update this review later once some updates are published. Free is NO EXCUSE for buggy software!

Extremely similar to another camera app called Camera FV 5. Lots of control over ISO and exposure, though it doesn't work reliably. Has a tendency to freeze, or the exposure compensation just stops working. No real instructions mean that I have to mess around to figure out what the various icons mean. For example, I'm assuming that the A L button means focus lock, but there's nothing that really tells me, and it doesn't really work. Still gonna hang onto it and keep playing, but it's not reliable enough.

Worked beautifully for the first time, and when settings changed, produced images are just 0KB files
