Lens glare creates haze and strange light effects on photographs. Glare occurs when bright sources of light, such as the sun, shoot directly into the lens. This article will discuss with you some tips on how to avoid glare destroying photos.
1. What is lens glare?
When the light source goes directly into the lens but does not appear in the photo, you will see fogging in the photo. This light fog reduces the contrast and saturation of the photograph, and the dark part lights up.
If the light source also appears in the photo, you will see the unwanted "light" like a "light path" connecting the light source to the camera.
These phenomena are caused by the diffusion and reflection of light in the lens. So the glare on zoom lens is more serious than that on fixed lens, because the former has more optical elements, and the light diffuses and reflects more.
But don't get me wrong, glare can also be a useful tool in photography. It's useful when shooting people in sunny weather, or lomo effects. At the same time, glare may become a serious problem. Your shooting angle may cause intense fog in the photo, even Photoshop can't help it. It's time for the lens shade to come on.
The following photo is a good example for me to use glare:
The hood should be a must in every photographer's bag, whether you are a professional photographer, amateur or beginner. The hood can effectively reduce the glare you don't want and let go of what you want. And the hood is not expensive. Who can say no?
But there are many kinds of shades, especially Canon. In fact, Canon says on its website that it offers 40 different types and sizes of hood. Don't forget that the lenses also have different sizes, each of which should be equipped with a specific size: 46mm, 49mm, 52mm, 55mm, 58mm, 62mm, 67mm, 72mm, and 77mm, of which 58mm is the most popular.
Canon's cheapest masks cost $29 (about 193 yuan) and the most expensive one is that you don't want to be scared, $860 (about 5,725 yuan). But that's a piece of cake compared to the EF 600 mm f/4L lens of $9,199 (about 61,245 yuan).
Anyway, let's go back to the topic of the hood. We don't need so many special shades. We just need the most common ones, usually rubber, unlike special shades, which are usually made of special plastic.
Below is my hood, basic model, three layers, made of rubber. Because it's rubber, it can be folded up. That's what three layers mean.
3. How to use it?
Most shades, including my own, can be screwed onto lenses or filters. After installing the shade, look at the viewfinder and make sure that the shade does not cover the viewfinder frame.
If you use an ultra wide angle lens and a long shade, dark corners will appear around the picture. This only happens when long shades and wide-angle lenses are used at the same time.
Even with the hood installed, the glare will not be completely eliminated. Try taking a few pictures of the sun, but don't take the sun in. Now the effect of glare is almost zero. But is that all we have to do?
4. Useful tips
We have accomplished the main task of eliminating the fog caused by glare. But what about the glare of the sun when it comes to taking pictures? Unfortunately, it's hard to get rid of this glare. Here are some tips to minimize this glare:
1. Use a shade. It's always useful to use a shade.
2. Reduce the number of glass elements through which light passes. Remove the filter in front of the lens. Replace zoom lens with fixed focus lens as far as possible.
3. Adjust the aperture. Different aperture values produce different glare.
4. The glare at the wide end of the zoom lens is more serious than that at the long end.
I know it's almost impossible to eliminate glare 100%, but at least you can reduce it. Exergy
