Mastering Light – Warm and Cool

In which we explore the color of light coming from different sources.

Light has several properties that are important to landscape photographers including quality, direction and color.

It is important to understand that different times of day and weather conditions will produce light of different colors.  Also, when you add artificial light sources the range of colors expands.

Our brains play tricks on us when it comes to color.  During twilight we don’t see that the light is a soft, delicate blue.  In fact, we don’t perceive any color cast at all.  But the camera is not fooled.  It sees what is actually there.  Take this image that I call ‘Breakfast’ as an example.

When drastically different light sources are set next to each other than our eyes can clearly see the difference in the colors.  In this photograph the interior of our home is illuminated by tungsten lights which give off a very warm color.  That’s why our homes feel so warm and cozy at night – because of the warm light emitted by tungsten lights.  (That will change as we replace the tungsten lights with CFLs or LED lights.)  Outside we have a foggy morning at twilight.  The sun is about 10 minutes away from rising.  And it’s clear the color of the outside light is blue.

If I was standing outside away from the warm tungsten light, my mind would trick me into thinking the light was not blue, just a neutral gray.  But the camera is not fooled.

So then why are we so easily fooled?  Because of perception.  Our brains receive input from all of our senses including our eyes.  And without us even being aware of it, this input is translated into something we are familiar with, concepts and generalizations we have learned from all the accumulated experiences of our lives.  And our brain overrides (manipulates if you will) the actual blue color of the outdoor light and we perceive it as neutral.

Our perceptions help us with everyday living.  They help to bring order to our lives from the endless bombardment of stimuli.  But perception interferes with the photographic process of seeing.  As far as day-to-day life is concerned we don’t need to see that the outdoor light is blue.  But as photographers, cultivating the ability to see beyond our perceptions opens up the world to us in ways we normally can’t even imagine.  And isn’t this what photography is all about?

Twelve Tips for Buying Your Next Lens

Know what to look for when purchasing your next lens and get the one that will serve your well for years to come.

A student of mine asked me for help in selecting a telephoto lens – what to look for and what to avoid.  I put down a few ideas for him and thought that maybe you might also find this topic interesting.

Sooner or later we all buy a lens or two or five or six.  I currently have four lenses in my camera bag – a wide angle zoom (17-40 mm, f/4), a mid range zoom (24-70 f/2.8), my workhorse lens (24-105 mm, f/4) and a telephoto zoom (70-200mm, f 2.8).

I have two ground rules for buying lenses that I have shared with many people.

1.  There must be a demonstrated need.  In other words, if you can’t realize your vision because you’re missing a particular lens then it’s time to consider adding one.  Students, friends and colleagues ask me if I think they should buy a hot new lens.  I always ask them, “What would this lens permit you to do that you can’t do with your current lenses?”  Often, the answer is that it does nothing new for them, they just think it’s a cool lens.

2.  Purchase the best glass you can afford.  You will go through several camera bodies in your career but you’ll never outgrow a high quality lens.

So those are the ground rules but what else is there?
