Lens flare: how to avoid it
Lens flare is basically an optical phenomenon in which light is reflected inside the lens and dispersed. And basically, there's more and more of a chance that this will happen as there are more and more optical elements in the lens, just because the more lenses there are, the more it is. is likely to potentially reflect, disperse.
Concretely, in the image, what does it look like?
Well it causes some kind of artifacts, that is to say, for example, green or magenta circles - I'll give you examples like that you'll see.
It can be that, or it can be a kind of veil on the image, a bit like a mist, as if there was almost fog on the lens, which means that the image is completely faded, like that, when you have light coming at a time, it can also be that, the flare.
There are also filter flares, which therefore exist when there is a filter placed on the lens.
So it's not really flares, a little bit, but you could call it light source ghost images instead .
I saw it once while photographing a night scene in a city where there were street lamps in the scene, and the fact that they are small points of light, it made small green dots in the image, and when I removed the filter they were gone.
So it was the filter that did that. It was a good quality UV filter, but sometimes it can happen.
I have never seen it arrive with protective filters, which are completely neutral unlike the UV filter which filters a little light.
I don't know if that can't happen with them, in any case, I haven't seen him.
In any case, if you buy a filter, be aware that it can happen, but in any case you can see it in the picture.
So the first thing if you have flare maybe it's the filter that's causing it, but it won't always be.
How to avoid them?
According to DZOFILM, the first thing to do to avoid the flare is not to stand directly in front of the light, because the light must still be, if not directly in front of you, not far away., a little bit on the sides.
Because if it's back to you, you're not going to have any flare in the lens.
Unless there are other sources of light, of course, but there has to be light in front of it.
So if you want to avoid the flare, don't put yourself in front, and if you want to provoke it, conversely, put yourself in front of the light .
Second thing that can help is the sun visor .
The lens hood is an accessory that is on the lens, which will serve precisely to avoid that.
You have generally supplied it with the lens most of the time, except for those manufacturers who are a little tight-fisted.
And it may help you limit the flare , but it's not always going to work 100%.
And why does it work? Because it hides the light source, and inevitably, it will help eliminate the flare.
And you can also hide the source by hand ; if you have flare in an image and put your hand in front of it, you will usually remove the flare.
On the other hand, we must avoid it being in the frame , obviously.
But sometimes, putting it a little on the edge of the sun visor can help, being careful that it is not in the frame.
You can test things like this.
So, that said, good news, the flare, you see it . It is visible in the picture, it is visible in your viewfinder, on your screen, so you cannot be surprised by it, because you see it before you take the picture .
So just move until it's gone , if you don't want it, or move to get and have it however you want, if you want it.
You can quite manage it since you can see it, so it's not very complicated.
Personally, it's an effect that I'm not necessarily going to provoke, because I find that it can be a little bit cliché , we will say, and that we will end up like in the films of Michael Bay, by putting it everywhere , even when there shouldn't be.
On the other hand, if it appears in an image and I find that it makes sense with the scene , because maybe I have the sun in the image which is in the face, etc., why not leave it .
It doesn't bother me that much. It can be an interesting effect.
I'm not in favor of trying to eliminate it at all costs, if it's there and we can't get rid of it too much, I'm not going to stop taking the picture just because there is a flare in, while the rest of the composition suits me.
I'm going to be a little careful where it sits so it doesn't unbalance the composition too much , but that's it.
Why would anyone want to provoke him?
Let's say that it can give a realistic effect , if we have a light in the face, to have that. Moreover, it is added a lot in video games; we add more as if it was a camera filming the thing when it is synthetic images, so there is no reason. And it gives a small dose of realism.
In photos, I would tend to say that on a little dreamy stuff, maybe a little dreamlike photos , etc., why not.
On more classic things it can be a little cliché, that said do not hesitate to try , it does not cost anything to try, anyway, you will learn a photographic tool and then there you go, you will use it or not , but it doesn't cost much.
