Flash Photograhy Effect

 

This short tutorial will show you how to emulate a flash photography effect used to enhance this shocking

render of a zombie attack!

Lighting

Create an light (set to  ). Position and rotate it so that it sits in front of the renderArea Quadcamera. Middle drag the Area light onto the camera in the outliner. This will group it to the camera,ensuring that when you move the camera, the light will follow. Increase the  of the light toExposure around . 4

Spread

We can use  in the Quad light to focus the light more on the zombie's face. In this case it hasSpreadbeen lowered to .0.2

Spread: 1 (default) Spread: 0.2

Low spread values can be noisier than the default high spread, so be careful when using them. The

lower the value, the more light samples will be needed to avoid noise in the shadows.

An alternate method for controlling how the light falls off in a scene is to add a Light Decay filter to

the light.

Volume Scattering

We can use to add a creepy atmosphere to the scene.Volume Scattering

 icon to the right of and select .Atmosphere Create aiVolumeScattering

 

 

Increase the  attribute of the slightly to around Density Volume Scattering  .0.005

That concludes this tutorial on how to create a flash photography effect. Have pleasant dreams!
