Options and Configurations to Consider When Buying a High-Speed Camera

When shopping for the most suitable high-speed camera for a specific application, it is important to determine exactly which features you will need and what your budget will allow.  Despite what you are looking to achieve, it is necessary to understand certain parameters and how they will affect your camera choice.

Several important technical aspects include the frame rate, shutter speed, and sensitivity. Knowing more about how these features work with typical high-speed camera applications will help you make the best buying decision. Here’s some tips from the professionals at Integrated Design Tools (IDT).

Why is the frame rate important in a high-speed camera?

The frame rate, also referred to as frames per second (FPS), is the amount of individual still images, or frames, that comprise every second of recorded video. More simply stated, it is how frequently frames are displayed. Typical video frame rates are 24, 25 and 30 FPS.  The human brain starts to perceive motion once the frame rate reaches between 18 to 26 frames per second. A high frame rate will result in a smoother, more seamless film or video sequence.

What is shutter speed and how is it set?

Shutter speed or exposure time is how long a shutter is open at a specific setting. It refers to the time a frame is exposed. Usually, the shutter speed is only a fraction of a second in the video. The denominator of that fraction is the figure used to set the shutter speed on the high-speed camera. One example, a shutter speed set at 50 results in frames that are exposed at 1/50th of a second.

What is the difference between frame rate and shutter speed?

A common mistake people make is to assume that frame rate and shutter speed are one in the same. They think that if they shoot with a 1/80th of a second shutter speed, that they are shooting 80 frames per second. This is incorrect. Depending on the camera types and the frame rate, they are most likely shooting at 24, 25, or 30 FPS.

How does light sensitivity affect image quality?

The ISO is the sensitivity level of a camera to available light. A higher ISO number has more light sensitivity, as a camera with a lower ISO number is less sensitive to light. The image sensor within the camera is capable of changing sensitivity. This component is the most important and most expensive part of the camera. It gathers light and transforms it into the target image. A camera with high sensitivity can capture quality images in low light areas without the use of a flash

Some additional factors you will consider include: quality image resolution, bit depth, color or monochrome, and camera size. You will need to understand the type of camera interface, how you operate the camera and whether it is difficult to use.

The right high-speed camera can greatly improve the quality of the shot and is a must for any professional photographer. IDT Vision offers a variety of high-speed cameras that match any photo need.
