Photography Tips - Lighting your Subject
Lighting your subject is, obviously, very important for the
successful capture of the 'perfect' image. The type and
intensity of the light can dramatically change the mood of the
photograph. Sometimes the effect is not obvious until the
picture is developed. Even with the digital camera, although you
can see an image immediately, the size of the view screen makes
it difficult to notice some of the differences.
The best way to learn how light affects the final image is to
experiment - ah the joy of the digital camera - you don't have
to wait to get the film developed to see the results! Try taking
pictures with and without the flash. Try using alternate sources
of light. Try using settings other than the camera default
settings.
1. Taking pictures with/without a flash Many cameras have an
automatic flash setting that I find most people used 99% of the
time. This may not always get you the result you want. For
example, on a very bright day your flash will not fire as your
camera senses enough light. However, you may find that the
shadows cast are very strong and detract from the photo. Most
digital cameras today have a setting called 'fill flash'. You
can use this setting to 'fill' in the shadows created by the
strong sunlight.
The opposite of this is to not use the flash when the camera
wants to use it. Each year at Halloween I love to carve
pumpkins. I try to create a new design every year and take
photos of them. I take them out to the front step (in the dark),
light the candles and position my self so that the flame is
hidden behind the design but the light comes shining through. If
I were to use a flash, all I would see would be an orange
pumpkin with stuff carved out - not what I want. If I turn off
the flash, I can then take a great photo that shows the design
as glowing against the dark pumpkin.
2. Alternate source of additional light (other than your flash)
Instead of using the flash to illuminate your subject, try
reflected light. Aluminum foil is a great reflector of light and
is cheap, lightweight and easy to carry. During a walk in the
woods, I found a small group of delicate pink flowers growing on
a moss-covered stump. There was no direct light on the flowers
and a flash would have completely washed out the colour. I used
my trusty piece of aluminum foil to reflect the light falling to
the ground a few feet away towards the flowers. You can adjust
the amount of light by moving or crumpling the foil.
3. Different settings
The default settings are not always the best. If you are taking
a photo of people with dark skin (not a portrait but a photo
including most if not all the body) and you use the automatic
settings, you may find that there is little detail in their
faces. Opening the shutter by one f-stop (maybe more if they are
really dark) should give you the light you need to show their
faces. On the other hand, let's say you have a scene where you
have some brightly colored leaves against a dark background. If
there is a fair amount of the dark background showing, using the
automatic settings will most likely overexpose the leaves,
losing the vibrancy of the colour. In this instance, closing the
shutter by one f-stop (or so) will bring capture the bright
colours. Remember that your light meter sets your camera to give
you a 'mid-gray' exposure. If your subject and background are
quite different in value, then the default settings are probably
not going to give you the best results.
For your experiments to have lasting value, record them. I carry
a small coil notebook that I can use to note anything different
I do. Some of the things I note include:
Identify your photos - In addition to numbering them, for the
first photo of a group of experiments, I describe it so I will
know which one it is when I get around to looking at them. For
me, this is the most reliable way to know to which photos my
notes belong as the camera date is usually set off and I may
take photos for days before downloading.
Note the ambient light conditions - indicate the type of light
(direct sunlight, full shade, light overcast, 60 watt bulb etc)
and the direction of the light in relation to your subject (from
right to left, front to back, etc). If you have an SLR camera,
note any variations in f-stop or shutter speed you make from
those derived from using your light meter.
When you have developed your photos (or downloaded them) look at
the results and draw your conclusions about what worked and did
not, what effects you liked and what you did not. Think about
what you were trying to capture in the photo and whether the
lighting you used enhanced or detracted from it.
Use your imagination and try these techniques - you have nothing
to loose and you may just have more fun with your camera!
