My camera has the ability to take 3 bracketed photos. With some trickery I can extend that to 5 fairly easily taking 2 sets of photos. The first set 2 stops under exposed and the second set 2 stops over exposed. From these photos you get 5 bracketed shots. You end up with 2 of the normal exposure shot so you can discard one of them. Well I have found the APP DSLR Controller for my Samsung Galaxy S2 Skyrocket phone. My phone has been updated to ICS 4.0.4 so I use an OTG (on the go) cable to connect the APP to the camera and control it remotely. With the APP I can easily take 7, 9, 11 or more bracketed photos. An example is shown on this page. This APP completely expands the capability of my Canon T4i camera. Here is a link to the APP in the Google Play Store [LINK]
