What is Burst Shooting?
Burst shooting, also known as continuous shooting mode, is a camera feature that allows you to capture multiple consecutive photographs in rapid succession by holding down the shutter button. This function captures fast action sequences, ensuring you do not miss the perfect split-second moment.
Originally developed for sports and wildlife photography, burst shooting is now standard across smartphones, action cameras, DSLRs, and mirrorless systems. It exists because human reaction time is often too slow to manually capture peak action moments such as a bird taking flight or an athlete crossing a finish line.
Key Takeaways
Captures multiple sequential images per second with a single continuous press of the shutter button
Measured in Frames Per Second (FPS), which dictates how fast the camera can capture images
Relies heavily on camera buffer capacity and memory card write speeds for sustained performance
Vital for action tracking, including sports, wildlife, action sports, and candid portraits
Can be limited by autofocus tracking capabilities and processing bottlenecks
How Burst Shooting Works
When you activate burst shooting and hold down the shutter button, the camera bypasses the standard single image processing sequence. Instead of capturing a photo, processing it and saving it to the memory card immediately, the camera focuses on raw speed.
Image Capture: The sensor captures sequential frames at the maximum speed allowed by the shutter mechanism, electronic or mechanical
The Buffer Stage: Because memory cards are too slow to write multi-megapixel images instantly, the camera temporarily stores these files in a high-speed internal RAM called the buffer
Card Writing: While the buffer holds the files, the camera processor slowly unloads them onto your memory card in the background
If the buffer fills up completely, the camera will slow down or stop shooting entirely until space frees up.
Technical Specifications Impacting Performance
Frames Per Second FPS
This metric defines the speed of the burst mode. Entry-level cameras might offer 5 FPS while high-end mirrorless models and smartphones can achieve 30 FPS to 120 FPS.
Buffer Capacity
The buffer determines how many consecutive shots you can take before the camera performance chokes. A large buffer allows for longer sustained bursts.
Shutter Types
Mechanical Shutter Uses physical curtains. It provides excellent image quality but is often limited to lower FPS rates like 10 to 15 FPS.
Electronic Shutter Turns the sensor on and off digitally. This allows for silent shooting and extreme speeds up to 120 FPS but can suffer from rolling shutter artifacts.
Advantages and Limitations
Advantages
Captures Peak Action Eliminates the reliance on human reflexes to time a shot perfectly.
Storytelling Sequences: Provides a frame-by-frame breakdown of a fast-moving event.
Better Group Photos Helps avoid closed eyes or awkward expressions in portraits.
Limitations
Storage Consumption: Fills up memory cards and hard drives rapidly with duplicate files.
Buffer Bottlenecks: Can cause the camera to temporarily lock up during crucial moments if the buffer overflows.
Increased Culling Time Requires significant post-processing time to sort through hundreds of nearly identical shots.
Continuous Shooting vs Time Lapse
| Feature | Burst Shooting | Time Lapse |
|---|---|---|
| Interval | Fractions of a second milliseconds | Seconds, minutes, or hours |
| Primary Purpose | Freezing fast action frames | Showing long term changes over time |
| Output | A series of high speed individual photos | A compressed fast forward video file |
| Shutter Press | Single continuous hold | Automated intervalometer programming |
Common Misconceptions
Higher FPS always means better photos
Speed is useless without accuracy. If your camera autofocus cannot track the subject at high speeds, you will simply end up with a high volume of blurry images.
Burst shooting reduces image resolution
On modern dedicated cameras, burst shooting maintains full sensor resolution. However, some smartphones may lower resolution or use video crops to achieve extreme speeds.
