What is lens flare?
Your camera lens is actually made up of lots of different lenses stacked together and if a very bright light source (especially the sun) gets into the camera at just the right angle then it will bounce around and reflect off all those surfaces creating a pattern on your image.

If you have a lens with lots of elements inside it you are much more prone to lens flare but it effects all camera, large and small, new and old.
Modern lenses, especially the pricier ones are all engineered to try and stop this from happening – they even have special coatings to help eliminate anything remotely flarey.

One of the first things I do with a new camera or lens is to shoot a few photos into the sun, just to see how it copes – what effect it gives.
Sorry to go all ‘health and safety’ on you, but PLEASE BE CAREFUL SHOOTING OR LOOKING DIRECTLY INTO THE SUN.

If you want to avoid lens flare…
One thing that will make a big difference to avoiding lens flare is to shade the sun from angling itself into your lens – a lens hood is ideal for this although you can just use your hand or hold a newspaper out of shot between you and the lens – it would do the same job.
I’ve found a great website called lenshoods.co.uk – they have templates for most lenses so you can print off and make your own lens hoods – what a great idea! No excuse for lens flare now – unless you want it, of course.

How to deliberately get lens flare…
There’s something about the pattens and washed out nature of lens flare that gives such a special quality to so many images. I think some of this is down it it mainly happening when the sun is low in the sky (the golden hour) and the light is always more magical then anyway. Also, lens technology before the 80s was less advanced than it is now and so it can instantly give a photo a retro feel.
- Shoot into the sun.
- Remove your lens hood.
- Set your camera to ‘manual’ – if you’re shooting straight into the sun it you’re going to need to give it a hand with the exposure settings.
How to cheat and add lens flare with Photoshop
Choose a photo that looks like it should naturally have lens flare, so one with a sun shining and lots of natural light.
The lens flare tool in Photoshop is destructive and will permanently alter you image, so start by creating a duplicate layer of your chosen image and work on this.
- Go to Filter > Render > Lens Flare.
- You’ll see a mini version of your image with a little cross – you can move this cross around (it represents the centre of you light source).
- Pick a style of lens – I use the one that’s closest to the actual lens I used to take the photo.
- Adjust the brightness until it looks ‘right’.
In this example I moved the light source to the top-left, set the brightness to 177% and selected the 70-300mm lens.
There’s no doubt that some photos are enhanced beautifully by allowing the lens to flare naturally in the sunlight – like any effect though it can be over-done, at least knowing where and when it’s likely to happen gives us some control over it.
