Ive been looking for an app that both takes, and saves, three HDR shots.
This is it!
I turn on Low Light Bracketing and put the camera in Bracketing Only mode. This takes three pictures the second you hit the button, one normally exposed, one over exposed and one under exposed. You can then process the photos later (a lengthy process in any app), and move on with taking pictures. This is especially useful when taking photos with people, or in a public setting where its not practical to use other apps, as time is a big factor.
Ive been using another app to get around this issue, but it only takes two HDR shots, omitting the properly exposed one. This created a problem, when the two exposures were too far apart for normal processing to give a pleasing result. If I had this app, it wouldnt have been an issue, as I wouldve had the properly exposed picture as well.
This app changes everything!
