If your photo is backlit, it may look overexposed. There are several ways to fix this problem. Read on to learn about Highlight compensation and Auto-exposure compensation. Infrared light is another culprit. By following the steps below, you can take your backlit photo to a more acceptable level. The result will be a better-looking shot. But what is backlight correction, and why is it important?

Highlight compensation

When the camera detects a scene that contains too much backlight, it adjusts exposure to create a more natural look. Light that falls in the shadows can also be compensated by backlight compensation. These techniques improve the quality of images by increasing the overall exposure to light. This is often a more cost-effective method of backlight compensation compared to other methods. Many cameras today have a feature known as “Wide Dynamic Range” (WDR) which automatically compensates for such situations.

Another way to adjust exposure is by using highlight and shadow masking functions. This technique aims to compensate for dark images when they are taken against a bright source of light. Backlight compensation also addresses the causes of dark images. This happens when the camera focuses on a bright source and some pixels in its light-sensitive matrix become saturated. These darkened areas will appear as blurry or blown-out. Therefore, backlight correction will correct these images.

In contrast, normal backlight compensation averages the window region on the video screen, increasing the gain of the entire video image. This can cause the window region to be washed out if the light source is strong. However, the highlight compensation mechanism does not produce such a problem. The advantage of this technique is that it avoids white-washing of the video image. This method is also ideal for shooting in areas that experience strong lighting.

Auto-exposure compensation

Exposure compensation can be useful when there is strong light coming from the front or behind an object. There are three modes to choose from: Normal, Spot, and Partial. Spot metering takes into account the light from the entire scene, while partial metering uses a smaller area of the frame. Partial metering is recommended when very dark regions appear on the edge of the frame. AE Lighting Mode will allow you to adjust the exposure in the right manner.

Using exposure compensation is useful in many types of situations, from shooting landscapes to taking portraits. In most cases, backlight situations are a prime example. Using backlight compensation on your camera will allow you to choose the right exposure for your subject. Cameras typically adjust their exposures based on the primary scene and will try to expose some areas properly while darkening others. While this is normal, using exposure compensation for backlight will prevent your photos from being overexposed or underexposed.

Another common way to use auto-exposure compensation is to adjust the aperture. In this case, you can increase the aperture or decrease the shutter speed. A good rule of thumb is to keep your aperture the same, while the shutter speed is at the same time set to a larger one. By doing so, you will get the best balance between the two. But be aware that auto-exposure compensation only works in certain shooting modes. You can’t use it if you are shooting in a scene where the light changes frequently.

Infrared light

The infrared LED technology is used for backlight correction. It is the most widely used form of light for this purpose, and is used in many devices. A high-frequency pulse signal is generated to trigger a backlight driver to produce infrared light. This backlight signal is synchronized with the exposure synchronization signal to enhance image quality and reduce photon emission. The on period of an infrared LED group is typically less than 100 ms.

Infrared illumination can be clocked so that it does not generate light that can be emitted into the atmosphere, and does not cause safety discussions. Infrared light has the advantage of providing an excellent contrast ratio. IR-corrected lenses produce perfect images, while standard lenses are unable to do so. Because of chromatic aberration, a camera may produce blurred images when exposed to infrared light.

An infrared backlight helps improve human facial identification in outdoor environments. It collects human facial features under the illumination of an infrared backlight and compares them with an image template. A group of infrared lamps is driven by a high-frequency pulse signal of 100 Hz to 10 KHz. This process can increase light intensity and reduce the effect of ambient light variations.
