Attributes of lights

Intensity -Power More or less light how much light emitted from the light source.

Fall-off/ decay - Fade out and weak. how much light diminishes away from the source light (fall -off)

Cone Angle - width of the lights cones of influence - area outside cone not illuminated

Penumbra Angle - fall off edge cone angle - more gives softer edge to the cone

Drop off - how much the light diminishes at the outer edges

Colour scene - set an RBG for the light - affects colour of the scene

Light Controls

Aim From/ Aim at - This is where the light is going to place inside the scene. Take any lights physically anywhere at any angle and control the distance of the drop off. Change the value and the width of the radius. Point of interest where the light can focus on.

Fall-off Rate -

Cone Radius -

Penumbra/Umbra control - Inside the middle . Control the intensity of the softness. Sharp or strong/

Non-linear fall-off - The distance/ spread and out far the light of the intensity fades.

All In One Control -

Good ways to use lights.

Look to photographers for good techniques.

Think in terms of Balance.

Avoid the overly dramatic. - only for cheesy soaps.

Look at natural lighting. - more aware of whats around you.

Avoid saturated lights and hues. - anything too vibrant or too bright.

Normally only need a few lights.

Avoid disco colours effects.
