Shooting into the sun can capture a high-contrast image that gives a strong sunlight vibe. It is often what landscape photographers like to do to create stunning images.
However, lens flare can also happen when the sunlight directly hits your lens. Some photographers like the flare because they feel that it enhances the mood and make a scene more artistic, but for landscape photographers, we usually would want to remove it, as it can cause a huge distraction from focusing on the scenery.
Here I want to share with you a simple technique to remove the lens flare, which I call "The Finger" technique.
The idea is to take two photos of the same scene using the same camera settings. The first one will be a normal shot, but when taking the second photo, you put your finger in the frame and block the sun.
With the sun being blocked, the flare disappeared.
So, you now have two photos, one with the flare and another one with a finger but without the flare.
Note: I have recovered the overexposed highlights for the left photo, which I usually do before removing the flare.
Then, you import both photos into Adobe Photoshop as two different layers in the same file.
Make sure that the photo with the finger is the top layer. Select the finger layer and click on the "Add layer Mask" icon while holding down Alt/Opt button to create a black layer mask.
From there, you select the brush tool with a soft edge, white foreground colour and 100% opacity.
Then, start to paint the flare area, to remove the flare. Pretty simple right?
If the exposure or colour of the finger layer doesn't match the background well, you can also add a curve or colour balance adjustment layer on top of the finger layer, right-click on it and choose to create a clipping mask. With that, you can make any necessary adjustment that affects only the finger layer.
Basically, what we are doing here is to put the area without the flare from the "Finger" layer on top of the bottom layer. It is one of the ways of using the Digital Blending technique in Photoshop.
If you take bracketed shots, you will need to take another extra "Finger" shot after you have done bracketing. Then, perform the usual exposure recovery step first and remove the lens flare.
Other than using the "The Finger" technique to remove the flare, if your lens has a UV filter attached, you can also try to remove the filter to see whether it helps to eliminate the flare. Unlike the glasses on our lens, which have a coating to reduce flare, a UV filter may cause more unwanted flare on your photo.
That's all for now.
