Cropping Your Photographs

Changing the Universe one pixel at a time...

When to crop, It's not just about the rule of thirds!

Crop to....

  • Straighten Horizons
    • The Human eye can detect a difference of 1/10,000th of an inch.
  • Eliminate distractions along the edges of the photo
  • Zoom in to magnify the subject (much better than using "Digital Zoom" in the camera")
  • Fit the subject to the "Golden Ratio"


Straightening Horizons and zooming

Cropping for Printing

It is helpful to know what the aspect ratio is of the images your camera saves at...

  • 35mm film has an aspect ratio of 3 to 2 (Most DSLR's adhere to that ratio)
  • There are some cameras that use a 4 to 3 ratio (same as the Old tube TV's and monitors)
  • Some Cameras use the wide screen TV format of 16 to 9
  • And! Some camera use a 1 to 1 aspect ratio (A Square) and others 5 to 4
  • And, yes some digital cameras will yet you choose!  3 : 2 or 4 : 3 or 5 to 4 or 16 : 9 and even 1 : 1

If you change the images aspect ratio to make a print with a different aspect ratio, say, 5 x 7  or 8 x 10
You WILL LOOSE part of the image! There is no way around it… Crop creatively!

The Golden Ratio ~ 1.61803398874989484820... Derived from the Fibonacci Sequence

golden-ratio-constructThe Golden Ratio can be calculated quite accurately from a formula derived from the following construction.


The actual value calculated is an irrational number = 1.61803398874989484820... (etc.)

Now consider the Fibonacci Sequence...

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946, 17711, 28657, 46368, 75025, 121393, 196418, 317811, ...
Where the next number is found by adding up the two numbers before it. Here's another way to look at the numbers...

To "get" close to the "Golden Ratio" divide any number by the previous number... the larger the numbers, the closer you get to 1.618033988749895

What does all of this mean?

The Universe that surrounds us is built from physical "constants" and common values from number sequences... and we are part of the universe. So, if we compose our photographs using the Golden Ratio, the more balanced the composition will appear to the human brain, the mind's eye!
