How can I take a good backlight photo?

However, it is a pity that this dramatic effect is often not obtained because of overexposure to the sky when shooting scenery in backlight. To avoid this mistake, you need to use a gray gradient filter to darken the bright sky, so as to ensure the accurate exposure of details. This is especially important for shooting in stormy weather, because the dark and dramatic sky will make the photos have a strong impact. You also need to use this filter when shooting sunrise or sunset, because if the sky and the sun are overexposed due to the foreground, the charm of the photo will disappear. The use of filters Most photographers use a gray gradient filter because it does not change the natural color of the sky. Usually two levels of gray (0.6) are enough to darken the bright sky. However, in a bright environment, you may need to use a three-level (0.9) gray gradient filter. When using the gray gradient filter, you must measure the light without the filter and set the camera manually. Once you have decided on your exposure value, you should carefully install the filter and cover the correct area. If there is a button on your camera or lens, you can narrow the aperture to preview it, and then press it, which will allow you to install the gray gradient filter correctly. You can change the connection between highlights and shadows of an image by increasing exposure, thus creating photos with different effects. If you start shooting with general exposure parameters and shoot a silhouette image of the foreground, you can shoot a series of additional photos with exposure of +0.5,+1,+1.5, +2, +2.5 and +3 files on the basis of the initial exposure value. This can be achieved through the compensation device on your camera. With every movement of exposure value, the background becomes brighter and the foreground becomes clearer. Avoid glare When shooting at the sun, one of the biggest things you encounter is glare. Glare will reduce the contrast, simple color effect, but also produce light through the whole photo pattern. Glare is mainly caused by the non-imaging light of bright light source entering the lens, such as the sun just inside the frame or just at the edge of the frame, which will cause this effect. The easiest way to avoid this effect is to add a hood in front of the lens to prevent those scattered lights from entering the lens. It is important that you always clean your lens and all the filters to ensure that they are clean. Because dust, fingerprints and so on will increase the risk of glare, especially when shooting directly at the sun. This dramatic photo shows the glare caused by direct shooting-you can see a series of light spots from the sun to the wooden pier.
