Last Updated on December 8, 2021 by Peter Wood

If you have been shopping for a television, a smartphone, or a camera recently, you will probably have heard of 4k video. Is there a 4k photo as well? The answer is yes. 4k means resolution, so there are both 4k videos and 4k images. But the new problem is what the 4k picture is. I believe that not many people could answer this question accurately, although someone has taken 4k photos by themselves. To help you understand this new concept, we will share some basic knowledge about 4k images. Whether you are a tech-savvy or ordinary user, you can learn something important about the 4k photos below.

Part 1. What is 4K Photo

4k is a video specification, which gets its name from the approximately 4,000 pixels of the width of the footage. And when we talk about 4k photos, they are usually extracted from 4k videos in ultra-high resolution. Colloquially, a 4k photo is a super high-quality photo. As I said, 4k means resolution refers to a horizontal resolution in the order of 4,000 pixels.

To help you understand 4k photos tangibly, we have compared them with the resolutions of HD pictures and ordinary pictures. The standard pictures resolution is 480p. HD photos are usually in 720p or 1080p resolution. And the resolution of 4k photos is 4 times of the 1080p images.

But what does ultra-high quality mean? It means you can see more details in a 4k photo. When you zoom in on an HD image, it will become blurry. On the contrary, Ultra HD photo makes it possible to take advantage of editing techniques that are impossible with HD pictures. Extra pixels allow you to zoom in or pan across the picture while maintaining high quality.

Besides ultra-high quality, the way to capture a 4k photo is different. When taking a 4k picture, you record a 4k video. But the result is a photo in 4k resolutions. 4k photography offers faster capture at 30 frames a second, which is impressive and records fast-moving action, like water flow.
