The Working Style of 4K Pictures
In fact, 4K picture is a burst shooting form. This is different from the continuous or high-speed capture provided by Lumix cameras that is about 12fps. That is because that function is utilizing the full resolution of the sensor, for instance, 16 megapixels.
The function that 4K photos offer is a faster capture at 30 frames per second, which is impressive and able to freeze quick-moving actions, while that is cannot be conducted by 12fps. For example, if you want to take photos for jumping players, you can use 4k pictures to freeze all the actions of jumping.
After all the jumping action finishes, you are able to choose a picture that has the best quality. Then, save the selected picture. Though the options vary in different cameras (depending on the power to offer to some extent), the working method is same on all types of cameras.
Why do you need to use 4k images? After reading the above description, you may have answers. It is very suitable for recording some games like basketball, football, swimming, and other quick-to-disappear moments.
If you are going to record the activity of animals, flashing starts, running pose, and other things that have high requirements for photo definition, 4k picture technology is a nice choice.
