The iPhone can capture a rapid-fire burst of high-quality photos to perfectly freeze a moment, a feature that Apple 'hid' in plain sight within the default camera app. Standard photography is handled so well by the iPhone, and for the most part automatically, that it's easy to assume that it can't manage special situations, such as capturing action photos, which is possible with burst mode.
Apple's iPhone camera has improved dramatically over the years, both in hardware and software capabilities. The very first iPhone had only a single rear camera and no selfie. The iPhone has evolved into a genuine challenger to dedicated cameras from that single-button, 2-megapixel camera that couldn't even record video. Modern iPhone cameras have 12-megapixel sensors backed by Deep Fusion, Apple's Artificial Intelligence-powered resolution enhancement software, good optics, and wide apertures. So the core technology is solid, allowing for some fun and creative possibilities such as burst photography.
The iPhone's burst photography mode is just a touch away whenever Apple's camera app is open, nearly as easy as snapping a regular picture. Instead of tapping the shutter button, the user can press, hold and drag to the left to begin capturing full-resolution photos rapidly. There's also a setting to take burst mode photos by holding the physical volume up button. The iPhone captures 10 frames per second and bundles them up as if it was a single photo. When reviewing this burst in the Photos app, a 'Select' button will appear at the bottom for users to choose which pictures to save from the burst. This allows capturing a long burst, then extracting the perfect moment and discarding any that were too early or too late. Apple posted a YouTube video showing the basics but didn't delve into how to get the best results.
Sharper iPhone Burst Photos
The best use of burst photos is to capture a split-second moment in full resolution. Whether that's a dog catching a ball, the top of a jump shot, or a pancake flip, there are particular moments that highlight the action best of all. However, the rapid-fire nature of burst photography means not all of the iPhone's features are available. For example, users can't use the flash with a burst, and Night Mode is also disabled, meaning lighting is critical to getting the best shot. While taking burst photos outdoors and in the daylight will yield the best results, simply turning on more lights and opening curtains might be enough.
The extra light isn't only for brightening the picture but also for sharpening it. The iPhone will expose the photo for longer in low-light conditions, which might cause motion blur. Shooting with the primary camera will give the best results if the lighting is a concern. Adding light or adjusting the exposure to be darker will help with sharpness. Swiping up will reveal the exposure button, which looks like a '+/-' symbol. Dragging the slider to the left will darken the picture and might help to make it sharper for burst photos. The iPhone's photo burst mode is just a press away and can be indispensable when there's a need to get a picture of a somewhat unpredictable moment at just the right instant.
