    I have never used the HDR setting until today while talking a picture. What is the difference when it is on vs off? What does hdr even do? Couldn't tell that much of a difference

    Check out page 233 of the iPhone User's Guide. I'd copy and paste it here but I'm having problems for some reason.

    I notice a big difference on my iPhone 4.

    When to use HDR

    Landscapes: A classic use of HDR in regular photography is on landscape shots with a bright sky above the horizon line and darker foreground below. iPhone 4 users who want to bring out more details in both parts of a landscape shot should turn on the HDR mode. One area that the iPhones HDR mode falls short is sunsets. In its attempt to lighten up the over-exposed sun, it also loses some of the beautiful red and orange coloring that makes the scene so stunning in the first place

    Outdoor portraits: The midday suns harsh light usually makes for unflattering portraits. It can cast strong shadows on a persons face and create dark circles around the eyes. It also bounces off of skin and accentuates shiny spots. The iPhones HDR setting can minimize the effect of these two extremes and create a more evenly lit portrait.

    However, if the subject is completely back lit, the limited powers of HDR mode might not be enough to brighten their face. To shoot a usable back-lit portrait, first tap to focus on the darkest part of the persons face. The background will become extrememly blown-out. After you take the shot, the final HDR photo will combine the properly exposed person with a slightly toned town background. (Many photographers use a fill flash in back lit portrait situations, but unfortunately the iPhones auto mode adjusts for the presence of the flash and skews too dark.)

    its funny because i have been fooling around alot with HDR today. I have never really used it for some reason don't know why. Here is what I see while using it.

    *Taking pictures when the lighting is perfect/right the photo while HDR is on definitely looks brighter and lighter and you can see a difference in the HDR pic and the regular one

    *taking pictures far away with HDR on the picture actually comes out darker than when the HDR is off

    *also when HDR is on sometimes the pics come out with alot of white in them.

    anyways what do you guys see when HDR is on and off?

    HDR stands for High Dynamic Range
    it is ") is a set of techniques that allow a greater dynamic range between the lightest and darkest areas of an image than current standard digital imaging techniques or photographic methods"

    see article below...High dynamic range imaging - Wikipedia, the free encyclopedia

    so with the iphone it is using the image processor to merge 3 exposures to get a higher dynamic range photo...

    why doesn't the HDR flash? i noticed that
    Because it takes 3 pics in rapid succession. One underexposed, one normal and one overexposed. The flash won't fire that fast and the flash would ruin the HDR.

    Beamed over the interwebz from my iPhone 4S using Siri.
