The vignette is the enemy. That’s a statement I’ve heard/read too many time. That’s not necessarily wrong, but it’s neither true. There are actually two kinds of vignette:
The optical vignette from the lens (or even worse: from the stacked filters in front of your lens), that you can’t control, but hopefully you can still do something about it. It’s the “bad” one, the one you usually don’t want.
The controlled, post processed vignette, created with your hands (well… mouse) in the way you want to make your photo even better.
Let’s focus a bit on them.
The optical vignette, aka “the one we want to get rid of”.
It’s the one people usually wants to avoid. Look at any lens review, any lens less vignette-prone will be praised. The vignette generally appears at wider apertures to disappear at smaller ones, usually after 2 to 3 stops. It happens when the lens’ rear elements are shaded by elements in front of them. We’re lucky though, with our modern RAW softwares we can just use a lens profile and get rid of this unwanted vignette. Let’s look at this shot of the Mercure Hotel in Algiers, Algeria, shot at sunset:
On the left hand side, the optical vignette has remained untouched. Look at the sky in the top left corner, how dark it become while it should stay even as it is on the corrected version on the right hand side. On the right hand side, I removed it with Lightroom, which make the whole image much clearer.
Of course, it doesn’t mean that the optical vignette is always bad. As anything in photography, one can use it in a creative way 🙂
The post processed vignette, aka “the creative one”.
Now enters the vignette the photographer adds to his perfectly-processed-for-hours photography. Usually the people I discuss with about this subject come with this question: “Are you crazy? Why on Earth would I want to add AGAIN some black corners to my photo?”.
The answer here is every time the same: “Who talked about black corner?”. Because like sugar or salt, a subtle touch of vignette can make your good photo look exquisite, but an abuse will make a mess! While there are a lot of usage for the vignette (make a photo look old, correct the exposure of the borders in an unorthodox way…) the main usage is to help the user focus on the subject but reducing slightly the impact of the borders. His eyes will naturally drift to the center where the magic happens.
Let’s continue with our photo of the Mercure Hotel in Algiers. The first one is the vignette free version, who got its optical vignette removed at import. Next, a vignette abuse: dark corners, it’s almost night on this picture. The second one is already better: the corners are darker but not black, the transition is smoother, but it’s still pretty heavy and obvious. Last but not least, the kind of subtle vignette I like: do you see it? A lot of people doesn’t, and sometimes me neither I must say 😀 In this case, once again it’s more obvious in the sky, at the corners. But look comparatively to the first shot: nothing is lost, all the details in the corners are still here, but your attention is drawn but the center where the subject is.
Adobe Photoshop Lightroom, or any RAW converter software, has a vignette tool with a few sliders:
Amount: controls the amount of vignetting, how dark (or light!) will it be. It’s the more critical slider.
Midpoint: controls where the vignette will start on your picture, closer or further to the middle of the frame.
Roundness: controls the shape of the vignette: rounder or more square?
Feather: controls the transition from the middle to the border: will it be a smooth transition, or a harsh, on/off style one?
Highlights: saves the highlights in the vignette.
Lightroom gives 3 styles of vignette:
Highlight priority: the one I use 99% of the time, it makes the edges darker, but tries to save the highlights around the edges to make sure it stays bright.
Color priority: can be a bit more subtle than the other two, but sometimes it gives some quite saturated results. It tries to keep the colors without darkening them too much, but I don’t really like what it does, I prefer a classic vignette.
Paint incrustation: it makes the edges darker, quite straightforward.
But wait, why post crop vignetting tool? Because if you crop your photo, at any time of your processing workflow, Lightroom will adapt the vignette to the new format. Piece of cake!
So, how to make those fancy subtle vignettes?
Here is what I do, there are countless possibilities:
I set the Amount slider around -20. It gives me the possibility to clearly see the shape of my vignette without being too dark.
Then I go and play with the Midpoint and Roundness sliders to give it its final shape. Here it really depends on what’s on the photo. For example for a portrait an oval vignette is usually the way I go. If I took a shot from a door I like to have a more square vignette that matches the door’s shape.
Once my shape is set, I move the Feather slider to adapt the transition on my needs: softer or harder. Sometimes you have to repeat steps #2 and #3 until you find the perfect settings.
Then I go back to Amount and in 99% of the cases I reduce it in the -5/-12 range. Don’t hesitate to activate/deactivate the post crop vignette to check the effect it has on the photo.
Only at this step I change the vignette style, however in the very, very large majority of he cases I just leave Highlights priority.
Last, if I have some highlights I don’t want to be affected by the vignette, I roll the Highlights protect slider.
And that’s pretty much it. After some practice you’ll see that it’s a 2 minutes job that can enhance quite a lot an already good picture!
Once again, this is how I do it. It doesn’t mean there is a standard rule, like everything in photography anything can be used in a creative way 🙂 But I’ve seen too often some great photos being penalized in competitions because of a too obvious/misused vignette. It’s a blade with two sides, be careful when vignetting.
See you next Tuesday for more processing resources!
