Here is a little program that demonstrates the use of the camera in the manual mode. You are prompted to take a photo which is then stored in Graphics/Camera Demo1/photo.png. PNG files are the preferred format. Once the photo is saved, the demo will attempt to display it to the screen. Some cameras take photos at such a high resolution that they cause out of memory errors when they are loaded for display. On my Samsung Galaxy SIII the image size is over 1.5mb. Each app is only allocated a small portion of the total memory available on a device, so an out of memory occurs. Fortunately my phone has a front facing camera which takes photos at a lower resolution and display without error. Even if high resolution photos can not be loaded, they will be saved to the sdcard correctly.
