We'll start by learning how to add lens flare, and position it exactly where we need it, using Photoshop's Lens Flare filter. Then, to keep things non-destructive, we'll undo the effect, add a new layer, and then instantly re-apply the Lens Flare filter using a handy shortcut!
For best results, you'll want to apply the lens flare effect to an image that has the light source actually visible in the photo, whether it's the sun, a studio light, or whatever the case may be. Here's the image I'll be working with (family on beach at sunset photo from Shutterstock):
Here's how it will look after adding the lens flare. The important thing to note is that the lens flare and the photo are completely separate from each other, so if I change my mind later and decide I don't like it, I can easy remove the lens flare and revert back to the original image:
The first thing we need to do is add a lens flare the way we normally would if we were applying it directly to the image itself. Even though we're going to be undoing the effect, this gives us a chance to position the lens flare exactly where we want it. To add the lens flare, we'll use Photoshop's Lens Flare filter. Go up to the Filter menu in the Menu Bar along the top of the screen, choose Render, and then choose Lens Flare:
This opens the Lens Flare dialog box. Photoshop's Lens Flare filter adds a simulated lens flare effect to the image, and we can choose from one of four different types of lenses (50-300 mm Zoom, 35mm Prime, 105mm Prime, and Movie Prime) in the Lens Type section in the lower left. Each one will give the effect a different look. You can try them out by selecting them and seeing what each one looks like in the image preview area. I'm going to stick with the default 50-300mm Zoom lens. You can also adjust the brightness of the lens flare by dragging the Brightness slider left or right, but again, I'll stick with the default 100%.
To position the lens flare where you want it, simply click inside the preview area. The spot you click on becomes the center of the flare, indicated by the little target symbol. You can also click and drag to move the flare around. To keep the effect looking as realistic as possible, you'll want to place the target symbol over the light source in your image, which in my case is the setting sun:
The only problem is that we've applied the lens flare directly to the image itself, and that makes it a destructive edit because we've made permanent changes to the original photo. It's much better to work non-destructively whenever possible, keeping the image and the effect separate from each other. Let's see how we can apply the lens flare non-destructively by taking advantage of Photoshop's layer blend modes.
Now that we know exactly where we want the lens flare to appear, let's undo the effect by going up to the Edit menu at the top of the screen and choosing Undo Lens Flare. Or, use the handy keyboard shortcut Ctrl+Z (Win) / Command+Z (Mac). Either way works:
This opens the Fill dialog box. Set the Contents option at the top to Black (*in Photoshop CS6 and earlier, the Contents option is named Use). Filling the layer with black will make it easy for us to blend the lens flare in with the photo, as we'll see in a moment:
First, the last filter we applied will always appear as the first option at the top of the Filter menu. To quickly re-apply the lens flare, just go up to the Filter menu and you'll find Lens Flare at the very top of the list. Click on it to re-apply it with the same settings as before. Or, an even faster way to re-apply the last filter you used is to simply press Ctrl+F (Win) / Command+F (Mac) on your keyboard:
All we need to do now is hide all of that solid black on the layer and blend the lens flare into the image below it, and we can do that easily by changing the "Lens flare" layer's blend mode from Normal to Screen. You'll find the blend mode option in the upper left of the Layers panel:
Since the lens flare is now on a separate layer above the image, we can turn it on and off by clicking the layer's visibility icon (the eyeball). Click it once to turn the lens flare off. Click it again to turn it back on:
You can adjust the colors in your lens flare so they better match the colors of your image. First make sure you still have the "Lens flare" layer selected in the Layers panel. Then go up to the Image menu at the top of the screen, choose Adjustments, then choose Hue/Saturation:
This opens the Hue/Saturation dialog box. Dragging the Hue slider left or right will shift the colors in your lens flare as if you're rotating them around a color wheel. Choose colors that are a good match for your photo. In my case, the lens flare already contains some nice reds and oranges that work well, but I'll drag the Hue slider a bit to the right to shift the colors more towards yellow:
Drag the Radius slider along the bottom of the Gaussian Blur dialog box towards the right. The further you drag the slider, the more blurring you'll apply to the lens flare and the softer it will appear. Keep an eye on your image as you drag the slider to judge the results since the amount you need will depend on the size of your image. In my case, a Radius value of around 12 pixels works well:
Finally, there's a couple of ways that we can adjust the intensity of the lens flare depending on whether you need to increase or decrease its brightness. If you're already happy with the way things look, you can skip this last step, but if you find that your lens flare is too bright, you can reduce its intensity by lowering the opacity of the "Lens flare" layer. You'll find the Opacity option in the upper right of the Layers panel, directly across from the blend mode option. The more you lower the opacity value from its default 100%, the more the lens flare will fade into the image:
The camera lens flare. For some, it's a mistake to be avoided; for others, it's an aesthetic choice. Depending on the project you may want to see a camera flare, or you may find yourself trying everything to eliminate them. We're going to talk about lens flare photography and the lens flare effect in movies as well.
Lens flare is caused by a bright light source shining directly into the lens. Also called lens glare, or light flare, a lens flare is a non-image forming light that is scattered in the lens system after it hits the front element of a lens. It reflects off the glass surfaces in the lens. Lenses with a large number of elements like zoom lenses are often most susceptible to lens flare. Flare is usually thought to be damaging to an image but there are times when it can be used to enhance the quality of the picture.
One way to avoid light flare is with a lens hood. The hood acts as a kind of shield blocking any scattering light from hitting the lens. The lens hood purpose: to prevent the sun from getting in your eyes, just as you would by placing your hand over your forehead.
While zooms are extremely convenient and offer a wide range of focal lengths, the complex system of many elements moving back and forth can cause tons of flare when extra light enters. Better quality prime lenses are a safer option if flare is a concern.
You can also simply adjust your angle. Light hitting the sensor is what causes sun lens flare, so avoid shooting directly into the sun. By only obscuring some of the light, you can produce more dynamic and creatively lit images.
This is actually just evidence that not all lens 'flares' are created equal. This is a typical, aesthetically pleasing flare on a light source that is reminiscent of film and SLR photography. The ghost reflections and multiple green dots all over the place are aberrations of a different character. That this is the type of lens flare you get on a M10 shows that it's not just 'physics' and that it's a lot to do with lens design, coatings etc. it would be nice if the iPhone hardware/camera implementation could be refined to produce this kind of smartphone photography result.
Lens flares are an interesting beast. At times we'll go to great lengths to try and avoid them by using things like lens hoods or by placing our hand strategically to avoid direct light from getting into the lens. Other times though we'll actually seek them out to give our images this washed-out, burst of light look.
What to do if you'd like the look of a lens flare in one of your shots, but couldn't quite get an actual one. Fear not, it's easy to do, thanks so the Render Lens Flare feature in Adobe Photoshop.
Apply the lens flare, and now fill the layer with black. You can do that by making sure black is selected as the background color, and hitting Cmd + Backspace (Ctrl + Backspace on Windows).
Now just go to the Filter menu and select the very 1st option (Lens Flare). This will apply the previously created lens flare with the exact same previous settings, but on our now black layer.
As a photographer, you have to understand light perfectly. You can do both accidental and intentional lens flare effects. Some photographers like this because it allows you to add some creativity to the shot. It all depends on your shooting style and the result you want to achieve. Lens flare in photography adds a touch of spice and uniqueness to every picture. You can use this simple effect to embellish absolutely any image you have. In this article, we will tell you how you can achieve this. Anyway, it is useful to know what causes lens flare so that you can learn how to prevent it or, in some cases, purposefully achieve this effect in your images.
