EX72 Atomospheric Perspective

Atmospheric Perspective is seen in art as old at 8th Century in Asia. It is something we can all readily see when we head outdoors and look at mountains off in the distance.

We know that things that look further away are:

  1. Bluer & colder colour temperature - caused by Rayleigh Scattering

  2. Less contrasty

  3. Have more blur and are less sharp

  4. Have a lower or compressed tonal range

  5. Look like we are seeing them through a haze

  6. Are smaller in size

We know things are closer to us when they are:

  1. Redder or warmer in colour temperature

  2. More contrasty

  3. Are sharper and have more details

  4. Have a larger tonal range (more likely to have a full range of tones from white to black)

  5. Look very clear and in focus

  6. Are larger in size

You can post process photographs to make them to increase the look of Atmospheric Perspective to give your work more depth. To do this you would:

  1. Sharpen and add clarity to the front of the photograph

  2. Reduce clarity and sharpening at far distance in the photograph

  3. Add warm hues to the front and blues / purples to the distance

  4. Increase the size of objects in the foreground and decrease their size in the distance

This weeks exercise is to experiment with Atmospheric Perspective. To intentionally seek it out and photograph it. You may wish to work with it in post processing if you wish, or out taking photographs.

If you are lucky or unlucky depending on your circumstances, you may encounter conditions that enhance depth in your photographs. These include, but are not limited too:

  1. Rain

  2. Mist

  3. Dust

  4. Smoke

Post three photographs that show your experimentation with depth with atmospheric perspective.

Notice how the clarity drops, and the tones get lighter in the distant trees while the ones in the foreground are sharper, rendered with more details and have a bigger tonal range. This is rising mist on the FIsh River.

Here is a great example of atmospheric perspective. This is taken with a telephoto lens, which intensifies the effect, in Namibia.

There is more going on than just atmospheric perspective in this photograph taken in the Botanic Gardens in the ACT.
