No matter how fancy Apple gets with its “True Tone” flash and backside illumination sensors, using direct flash to take a picture in the dark pretty much guarantees that a photo will be washed out and kind of weird looking. Professional photographers never rely solely on the direct flash of a camera, no matter how expensive. Most of the time, some additional light source is reflected from some other direction or against a wall to give the effect of diffused ambient light, which greatly improves the effect of flash.
When it comes to iPad photography, the tablet doesn’t even get the pleasure of having a flash at all. You are simply left in the dark when trying to take pictures on your iPad. I’ve always felt that this was unfair.
