reproduction of colours.
The rules for taking colour photos of firework displays and thunderstorms are the same as for black-and-white pictures:
shutter release at B, shutter open, stop 3.5, focus at infinity.
The shutter is closed when the photographer considers that the film has accumulated a sufficient store of light impressions.
The old trick of using an ordinary electric lamp for lightening the shadows of an object near the window will not work
with colour film in the camera if daylight material is used. The side of the object which is lit by the electric bulb appears
reddish on the picture. If, on the other hand, you use an artificial light colour film the colours on the daylight side of the
picture are not true to life.
Once they have been exposed, colour films should not be left undeveloped too long. Otherwise the colour reproduction
may suffer. So once a film has been started, finish it off within a reasonable time, and when the whole film is exposed. do
not leave it lying about for longer than you need.
In all cases where colour reversal films are not returned from the processor already cut and mounted, it cannot be too
strongly emphasized that they must be divided into individual pictures immediately on receipt, even before examining
them. Each individual film should be mounted. Only then are they in a fit state to be handled and admired. This is the only
way to prevent damage, finger marks. scratches and so on.
Colour films and prints should not be exposed for long to bright sunshine, or the colours may fade.
