One should not forget that it is possible to paint after a
'normal' shot is taken to add light and shadow but without the ability to change
the direction or style of the lighting (as one can in a full light painting
session).
Below is a subtle change, but it brings the picture alive and
adds depth. Notice how the columns become 3D when you hover the mouse over
the original image.
The following 4 renditions show how easy it is to change the emphasis of
a picture for painted shots. This light painting pose was held for 3
minutes during which time I took 36 exposures of 3 seconds each at f/20, ISO
200. The 'trick' with a model is to paint moving from top to bottom, so
that in this case the face only had to be stationary for under a minute for the
10 exposures I took.
I could have changed the emphasis of the whole pose, but this
just show different renditions of the face. This technique really allows
you great freedom of expression.
Lighting a whole room is real fun and this was my first attempt. I
painted using a small LED panel on 4 second exposures plus a very underexposed
shot to capture the view out of the window. Hover to see the painted
one...
The above painted image is actually a very low contrast rendition of the one
below as I found I had revealed too much detail and texture from my angles of
painting - making the image seem very busy and unreal.
It doesn't always work out - I think that this example from James F
Caldwell's booklet, does not improve upon the 'standard' photo.
