Using a small pocket torch as a light source can be the recipe for some very
creative lighting effects.

The technique, known as painting with light, allows you to illuminate
precise areas of the subject by pointing a torch at it during the exposure.
The trick is to build up the amount of light on the subject so that it
is correctly exposed.
Any standard torch will do but the powerful compact models from the likes
of Maglite are perfect. You can also often adjust the beam from a wide
spread to quite intense making it useful for different types of subject.
I sometimes use a cone made from black card to make an even more precise
point light source.
This technique can be achieved with any camera although working with
digital is much easier as the exposure is quite tricky to calculate with
a film camera and you need to bracket to stand more chance of getting
good shots. Start by setting the camera on auto exposure and bracket two
stops over and under making notes so you can refer to them when your photos
are printed. With a digital camera you can preview the photo after you've
taken it and shoot again if the result isn't quite right.
Focus and set the camera on focus lock so that it isn't fooled by the
Mount the camera on a tripod so you can control the torch with one
hand while tripping the shutter with the other.

pointing from the front, while the right hand shot has light from the right
side. The narrow beam ensures the rest of the wooden sculpture remains in
Below are four examples of a pair of mushrooms. The first is with normal flash
and while okay, is not very interesting. Bring the torch into action and the
results become far more creative. You can either hold the torch still or move
it around to avoid patterns from the bulb or hot spots appearing.
One thing you'll probably have spotted at this stage is the colour. A torch
has a colour temperature that's much warmer than daylight so pictures illuminated
with it will be very warm or orange. You can use a blue 80 series filter to
correct this with film, whereas a digital camera has an automatic white balance
control that adjusts to make the picture look like daylight. When necessary
you can override the white balance and set the colour correction manual.
The final example below shows the difference you can make by moving the torch
around the subject, in this case bananas. Different angles produce very varied
lighting. It's all about experimenting and when you use digital it costs you
nothing to try.
