Get the perfect exposure…Part 2

0

If you are still unsure about getting the correct exposure, there is a cheap but very effective device called an 18% grey card that can limit your frustration, if used correctly.

When light falls upon a certain object; if the object is too dark your camera or meter will automatically give you an over-exposed reading. This also happens when we take a reading from something that is too
bright – the meter gives us an under-exposed reading.

We need to find a mid-tone object for our meters to read the proper exposure.

Sometimes if we are taking pictures in a high contract scene a mid-tone object is impossible to find. 18 % grey is the mid-tone between pure white and pure black.

An 18% grey card will record the exact light that will touch any object. Start by placing the grey card where you are going to take your reading, point your camera or light meter at the grey card – your meter should read the exact light that falls upon the card.

These cards can be used for all types of photography. If you are taking a portrait place the grey card beside the subjects’ face. This will give you an exact reading and help to capture perfect skin tones.

We don’t need to understand the full science of how this works, but knowing a little doesn’t hurt. All light-meters are calibrated to produce an exposure of 18% The grey card reflects the exact same reading.

This card only costs a few Euro, and most decent camera stores should sell them. The 18% grey card should become an important part of your equipment. The grey card can be used if you shoot with digital or film cameras, and whether you use black and white or colour film.

Where there is no vision, the people perish.
Proverbs 29:18

The earth is the LORD’s and everything in it, the world, and all who live in it; for he founded it upon the seas and established it upon the waters.
Psalm 24:1-2

He makes springs pour water into the ravines; it flows between the mountains. They give water to all the beasts of the field; the wild donkeys quench their thirst. The birds of the air nest by the waters; they sing among the branches. He waters the mountains from his upper chambers; the earth is satisfied by the fruit of his work.
Psalm 104:10-13

Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they?
Matthew 6:26

How many are your works, O LORD! In wisdom you made them all; the earth is full of your creatures. There is the sea, vast and spacious, teeming with creatures beyond number living things both large and small.
Psalm 104:24-25

Sometimes I do get to places just when God’s ready to have somebody click the shutter.
Ansel Adams

When you photograph people in colour you photograph their clothes. But when you photograph people in B&W, you photograph their souls!

While there is perhaps a province in which the photograph can tell us nothing more than what we see with our own eyes, there is another in which it proves to us how little our eyes permit us to see.
Dorothea Lange

When words become unclear, I shall focus with photographs. When images become inadequate, I shall be content with silence.

You’ve got to push yourself harder. You’ve got to start looking for pictures nobody else could take. You’ve got to take the tools you have and probe deeper.
William Albert Allard

If I saw something in my viewfinder that looked familiar to me, I would do something to shake it up.
Garry Winogrand
