![]() ![]() Lens Quality – Optical quality of the lens can definitely impact lens flare.Telephoto lenses, on the other hand, are much worse in this sense because they are very complex and they can easily amplify everything. Focal Length – Wide lenses are designed to handle flare well.Lens Elements – The more lens elements, the more lens flare can potentially show up in your images. ![]() There are many factors that can impact this effect in your images. As you stop down (use more narrow aperture values), the flare will become more defined. For instance, if your lens is opened up (the depth of field is shallow), the flare will look more like a blob, without definition. Although flare is caused by internal reflections, it often requires a very strong light source (such as the sun) in order to become visible in a photo.įlare looks like a polygonal shape and its exact shape depends on a number of factors. Light sources always reflect a small fraction of light. However, this coating can’t completely eliminate lens flare. Lens elements contain some type of anti-reflective coating which aims to reduce lens flare. Essentially, non-image forming light is stray light. The flare is caused by non-image forming light – this kind of light does not pass directly along its intended path but instead reflects internally on lens elements before finally reaching the sensor. Photo by Josh Blanton How Lens Flares HappenĮvery camera lens consists of several lens elements. Understanding lens flare can help you use it or avoid it - you just need to understand what kind of atmosphere you want to achieve in the final version of your image. However, some types of lens flares can make images more artistic. What’s the main problem with lens flares? It can lower the overall contrast of a photograph a lot, which can be problematic in both portraits and landscape shots. It’s easy to identify lens flare – it has a typical polygonal shape, with sides that depend on the shape of the lens diaphragm. The flare appears when the light that doesn’t form the image (stray light) enters the lens and hits the camera's digital sensor (or film). You should understand why lens flare happens – we will try to explain this phenomenon in simple words. Read on to learn when and how to shoot with or without lens flares. And, to be fair, quite often it looks pretty cool. These days, not only many photographers do not mind some lens flare, they actively seek to get it to add some creativity to their shots. The so-called flare look can be used creatively! You don’t have to use a lens hood each time you plan to shoot in a strong light. Equipment like lens hoods was invented to help prevent it. Flare, which is basically a light scattered within the lens due to unplanned reflection and lens impurities, was considered something that ruined a photograph. For many years in photography, lens flare was actively avoided by photographers. ![]()
