Removing Vignette From Photos – Reversing The Dark Shadow In The Corners

Hey,

When you take photos you may notice a darkening in the corners of the image. This is called vignetting, and is a limitation of the lens you are using to produce a clear image, although it isn’t too common on your iPhone, certain lens – particularly SLR lens and macro lenses will produce it. Good camera settings will help you avoid this for the most part, however sometimes it is easier to remove post processing. In this example we are going to use the built in app Photos to remove it.

The Photos app within your Mac is really powerful and has a wide variety of filters and tools to manipulate your image, it covers some of the basic Photoshop tools and is a great for making your images perfect and can mask those imperfections.

In this example you will notice the shadowing in the corners of the image, this is the vignette. It was cause via a Macro lens on a Nikon SLR. Although it is standard for the lens, it doesn’t make the image look very good. If like the cufflinks featured in the image you can find them here.

To edit the image, select the image and then select Edit in the top right corner. The background will go dark and you will be given a set of options. Select the adjust option from the menu options on the right hand side.

At the top of the adjustment options there will be a blue add option. Select this and select Vignette from the list, if you want to keep this option select permanently press the ‘Save as Default’ option.

This option is intended to actually add vignette into the image. Fancy, post processed images which are usually on Twitter or Instagram, usually have a lot of vignette. The option however allows you to reverse the vignette, by adding a white shadow to the corners. This in effect removes the vignette.

To remove the vignette, slide the Strength slider to the left into the minus region. This will add a white shadow to the corners, removing the vignette. Adjust the slider to suit your image. The radius option will allow increase the size of the effect going closer into the centre of the image. The Softness option will change how sharp the transition is. Play with the sliders.

I love this tool. Especially when taking image with a macro lens, as it cleans up the image. It will work with most images you just have to adjust the settings as needed. In theory you would try and remove it with the lens itself, but sometimes this is not always possible.
