How do you Vignette?

Adding a vignette to an image involves adding a subtle (or not so subtle) edge effect to it. A popular vignette technique involves darkening the edges of your image – it gives the image a slight border which helps keep the viewer’s eye in the photo. This is an effect which has been popular for years and which was is a feature of some classic film cameras such as the Holga.

Nowadays many photographers and digital artists use vignettes as a way to finish their images. There are lots of ways to add a vignette to an image and here are some of them. I’ve included methods that work with Lightroom, Photoshop and Photoshop Elements. The latter process will work with most photo editing programs.

Lightroom 2

To add a vignette in Lightroom, move to the Develop module and choose the Vignette options. Set the Post Crop Amount value in a negative value to darken the edges. Set the Roundness to a low value such as -70 to get a rectangular vignette and set the Feather to around 50 so it is soft but not too soft.

Photoshop #1

A simple way to add a vignette in Photoshop is to use the Lens Correction filter. Choose Filter > Distort > Lens Correction and adjust the Vignette amount to the Left to a negative value and the Midpoint to the left to bring the vignette into the image more.

Photoshop #2

Another way to add a vignette in Photoshop is to use a Layer style. This has some benefits and one is that the method works on just about any size image and it’s simple to do once you have the Style created.

Make the background layer a regular layer by double clicking it and click Ok. Select the Add Layer Style icon at the foot of the Layer palette and choose Inner Glow. Set the Color to Black, set the blend mode to Darken or Multiply and adjust the Size so you can see the edge. You can save this as a style preset and you can then record the process of adding the style to the layer as an action so that you have a one click vignette solution.

Almost any photo-editing software

If your software supports layers and layer opacity then this method should work just fine in most photo editing programs. I’ve used Photoshop Elements and you should check your program’s help if you are unsure how to perform these tasks in your software.

Add a new layer using Layer > New > Layer and use the Rectangular Marquee to select around the inside border of this layer leaving a small margin. Choose Select > Inverse to invert your selection so the border area is selected. Now use the Paint Bucket to fill the area with black or dark brown. Choose Select > Deselect.

Choose Filter > Blur >Gaussian Blur and use a high radius value to blur the edge and soften it. Adjust the Layer Opacity to blend this edge into the image underneath and, if desired, set the Blend Mode to Darken or Multiply.

Cool Photo Apps #2 big huge photo prints


Not all good applications come in big shinny boxes like Photoshop and Photoshop Elements. Many cool photo apps are available on the web and they’re free.

These apps do things that other programs don’t. They are fun to use and practical. In this Cool Photo Apps series I’ll show you some of these.

For resizing images to very large size, there are a couple of handy tools you can use. One of these is Rasterbator which you can find at http://homokaasu.org/rasterbator/. You can use this tool online or you can download it to your computer and use it from there. One benefit of downloading is that you’re not limited in the size of the starter image you use.

Rasterbator upsizes your image to anything from regular poster size to a gigantic 25 meters in size.

Here’s how to use the online version:

Step 1
Click Rasterbate Online and select to upload an image from your computer or use an image from the web. There is a maximum upload size of 1 MB. Once the file is uploaded, you can crop the image although you’re really better off doing this before you upload it.

Step 2
Select the Size option and select the final print size for your image. Each of the grid squares is one sheet of paper and you can add more sheets or reduce the number of sheets by clicking the More Sheets or Few Sheets buttons. The finished size of the project appears below the image so you can juggle the size to fit your needs.

Be sure to select the paper size as Letter and use either a vertical or horizontal orientation as required. It’s important to select your page size here as it will be too late once you’ve created the PDF file. Click Next to continue.

Step 3
The program will warn you how many sheets of paper the project will require and, if you’re happy to continue, click the Continue button – you’re not actually printing yet, just confirming you want a document that big created for you.

Step 4
Set the options such as drawing a border around the rasterbated area which will give you cutting lines that you can use later on to cut out the images before assembling the panel. Select the dot size to use from the list or use the default size. You can choose to create the image in black and white, some other colour and white or colour.

Step 5
Click Rasterbate when you are done and wait as the PDF file is created for you.

Step 6
Download and save the pdf file and then print, cut and hang and enjoy your masterpiece at your leisure.
