What is it?

Exposure bracketing allows you to take 3 images at 3 different exposures which gives you the security of knowing that one of them will have captured the light in the best possible way.

It allows you to capture every detail in a scene. It helps you avoid overexposing or underexposing your photos. It gives you more options to choose from when you’re editing.

AEB

Many digital cameras, as well as a few drones, include an Auto Exposure Bracketing (AEB) option. AEB is very useful for capturing high contrast scenes for HDR. When AEB is selected, the camera automatically takes three or more shots, each at a different exposure.

AEB is like having an automatic version of exposure compensation that gives you a number of variations to choose from.

What is exposure compensation?

Exposure compensation basically helps you override automatic exposure adjustments your camera makes in situations with uneven light distribution, filters, non-standard processing, or under exposure or overexposure. It lets you take control of your image’s brightness by manually increasing or decreasing exposure.

The formula is as follows: exposure time in fractions of a second >=(equals) shutter angle in degrees / (over) 360 degrees x (times, as in >multiply by) the frame rate.

What are HDR photos?

HDR describes a type of photo that captures a dynamic range that can’t be achieved in a single photograph.

HDR (high dynamic range) helps you get great shots in high-contrast situations. The iPhone camera takes several photos in rapid succession at different exposures and blends them together to bring more highlight and shadow detail to your photos.
