Light - Camera - Practice. Chasing Light.

In my last post I talked about – photography is all about chasing light. That does not mean, we need to run after street lights, tails lamps etc. Chasing light for us photographers means understanding light.

Hold on! You said you will make us a better photographer and now you are turning us into physicists.
Not exactly, we don’t need to understand photon and stuff. We just to understand the basic and how it effects a photograph.

So let’s go back to school and recap how we see things.
Light from a source, reflected by an object is captured by our eye.

 Now we add in a camera in front of the eye and the scene is recorded on device sensor.

So let’s first understand the major factors to consider and then we will see through some examples to put theory into practical perspective.
Source – Natural vs. Artificial light- For us natural light source is sun during the day and moon at night. Artificial light is anything from candles to bulbs to external flashes.
Understanding the source is important as it will help you determine the overall mood and other aspects of a photograph. And there is no good or bad light source. If you ask a landscape photographer, he will tell you natural light is the best. If you ask the same question to a studio portrait photographer, he will swear by artificial light.
Direction of light- The second thing to consider is the direction of light. It simply means at what angle the light is being reflected towards the camera.
Color Temperature – What! Colors don’t have temperature. I agree. But just to remember there are warm colors and cool colors. Just imagine a color and if it makes you feel cold it is the cold color and vice versa. Imagine color blue and immediately your mind perceives sky, water bodies and make your feel cold and relaxed. Whereas shades of red/orange will make you feel warm because your mind associate those colors with warm things like fire or sun.
Enough of text, now let’s get to examples and dissect them to understand lighting in each situation.
(Disclaimer – I shoot exclusively with available light, if you are looking for advice on external flashes and lighting systems, I am not the correct guy to follow)

Natural Light Backpack Nirvana
Natural Light
Here you can see that the light is natural (from sun), being blocked by something which is allowing partial light to fall through, coming from top left direction.

Artifical Light Backpack Nirvana
Artificial Light
 Here the light source is in front (candle), with light being reflected by the metallic surface.

light one backpack nirvana
Light Direction One
Here the light source is again in the front.

Here the light source is on top with beamed light falling on the subject.

Here the light source is coming from top right, as you can make out from the direction of shadows. The intensity of light is also hard and close to subject, which you can make out as the bell on right got more light than the left one.

Leaving three four images for you guys to dissect in comment section. Give it a try will be a good exercise.
