How to Take HDR Pictures with the iPhone

If you don’t know what HDR is you’re going to love it, especially on the iPhone.

When you take a picture the camera determines the exposure level based on how much light there is available which ensures a properly exposed image on the object you are focusing on.

However, if the lighting conditions in the photograph vary, for example the foreground is dark and the background is bright and the camera uses the foreground to set the exposure level the background will appear washed out.

Taking Pictures at Multiple Exposure Levels Takes Time

This is usually resolved by taking multiple photographs (usually three) at different exposure levels and combining them.

This can be a time-consuming process if you want to do it via a photo-editing application, but with the iPhone it is literally a snapshot away.

HDR on the iPhone 4 Is Simpler

When you enabled turn on the HDR feature on the iPhone every time you take a photograph the iPhone will save the original non-HDR image and the HDR photograph at the same time.

The guide below will show you how to take HDR pictures using the iPhone.

B. You can tell HDR images apart from others when they are viewed full-screen.

Notice the HDR icon on the top left corner of the photo. This indicates that the photo is an HDR photo.

  • Great read. Unfortunately, I don’t have an iphone, but I do love taking HDR pictures!

    I’m curious as to the format that the iphone uses to take the pictures. For me, I use a point and shoot camera, then take ~5 .jpg pictures at different exposure settings and use photoshop to layer them together to create the final image. I think it’s possible to take HDR pictures in one fell swoop however, if you use a .raw file format I believe. Do you know if the iphone uses .raw file format, or a different format? Overall, great news because I absolutely love HDR format and can’t wait for it to become more mainstream!

    • Scott,

      As I understand it the iPhone takes three pictures in succession (overexposed, normal, and underexposed). It then combines them behind the scenes. One of the problems with HDR on the iPhone is that if you move while taking the picture you will notice it in the final image (it appears a bit blurred), but other than that it is great. I too love to shoot HDR.

    I think it can help me as I am fond of taking catchy pictures and this can make me updated with all the required things.
