I am a huge fan of lens flare and all the cool light effects it can give to a photograph. Before I go into sharing how to create a lens flare in photoshop, I want to share what a lens flare is and how to achieve it in camera.
Lens flare happens when light hits the digital sensor (or film) causing a reflection of light on the image. The light can give various shapes of light effects.
I recommend moving around your subject and allowing some light to peak in. For example, this image below, I angled myself where the plane wasn’t completely blocking the sun so I could get some nice flare on the image. (This is a natural lens flare)
To achieve some more creative lens flare, grab a prism or a copper tube (about an inch), place it in front of your viewfinder and allow the light to hit it to create some unique flares such as the ones below.
Do you want to reduce the amount of lens flare you might be getting? This effect can be reduced by adding a lens hood as well as positioning yourself where the light isn’t going directly (or even indirectly) into the lens.
