can also get anything in between:<br />

a medium-size light of whatever<br />

size we want.<br />

To get from <strong>the</strong> harsh, unflattering<br />

image <strong>on</strong> page 18 to <strong>the</strong><br />

improved light in <strong>the</strong> photo <strong>on</strong><br />

page 16, we put a large sheet of<br />

translucent white diffusi<strong>on</strong> material<br />

between our subject and <strong>the</strong><br />

flash. Voilà! What is diffusi<strong>on</strong><br />

material? Many things: cloudy<br />

sky, thin white paper or plastic,<br />

foggy or smoky air. All of <strong>the</strong>se<br />

can turn a small light into a bigger<br />

<strong>on</strong>e. The distance between<br />

<strong>the</strong> light source and <strong>the</strong> diffusi<strong>on</strong><br />

also affects <strong>the</strong> effective size of <strong>the</strong><br />

light: <strong>the</strong> far<strong>the</strong>r away, <strong>the</strong> bigger<br />

<strong>the</strong> light. Notice that this is exactly<br />

<strong>the</strong> opposite of <strong>the</strong> effect of<br />

moving an undiffused light far<strong>the</strong>r<br />

away! Moving an undiffused light<br />

far<strong>the</strong>r away makes it a smaller<br />

light: think of <strong>the</strong> unclouded sun,<br />

93 milli<strong>on</strong> miles away. Moving<br />

a small light far enough away<br />

to fully light a large diffusi<strong>on</strong><br />

material evenly makes it softer.<br />

Try putting your small flash directly<br />

against a white shower curtain.<br />

(We’ll talk about white shower<br />

curtains a few times, because<br />

it’s <strong>the</strong> largest piece of diffusi<strong>on</strong><br />

material many people have where<br />

<strong>the</strong>y live.) Take a picture of almost<br />

anything, move <strong>the</strong> light as far<br />

Translucent? Transparent?<br />

What’s <strong>the</strong> difference? Both<br />

words describe material that<br />

lets light through, and many<br />

people use <strong>the</strong>m interchangeably.<br />

They mean different things,<br />

though, and photographers<br />

talking to each o<strong>the</strong>r have to get<br />

<strong>the</strong> terms right.<br />

from <strong>the</strong> curtain as possible, and<br />

<strong>the</strong>n shoot ano<strong>the</strong>r picture of <strong>the</strong><br />

same subject without moving <strong>the</strong><br />

camera. (You may or may not<br />

need to adjust exposure.) If you<br />

d<strong>on</strong>’t already understand <strong>the</strong><br />

Transparency allows an image to<br />

pass through. Our neighbor’s<br />

cat looks like a cat through<br />

a clear glass window. But if<br />

<strong>the</strong> same window fogs or ices<br />

because of wea<strong>the</strong>r,<br />

we still see light<br />

coming through but no<br />

identifiable cat. That’s<br />

translucency.<br />

difference <strong>the</strong> effective size of <strong>the</strong><br />

light makes, you will see it here<br />

and never forget.<br />

A large light is <strong>the</strong> kindest light<br />

for faces. We also added some<br />
