SPEED
3200
1600
800
High-speed film has larger grain size,
is less sharp with lower saturation in colour.
However high speed film can be used in low light
situations giving higher shutter speeds,
allowing hand holding of the camera with sharp results.

GALLERIES MEDIUM
SPEED 400
200
100
Medium speed film has small grain size with excellent sharpness.
colour is good with high saturation medium contrast.
Allows hand holding in good conditions.

INFORMATION SLOW
SPEED
50
25

Slow speed film. Very high sharpness and contrast
Rich saturated colours.
Require careful exposure and good lighting and tripod for best results.

The higher the films speed, the greater its sensitivity, therefore the less light required for a given density on film. Different films give different results even at the same speed, especially in colour Try out different makes carefully to get the results you like.
Remember that the better the processing the better the results, all else being equal. Take care that the film is processed to the highest standards. In black and white development there is great scope for experimentation for desired results with different films and developments.
