P.rinting your own Photographs JOHNSONS OF HENDON LTD MAKING CONTACT PRINTS Printing is always the most fascinating part of photography because it is at this stage that the finished picture is first seen. Contact Prints (so called because the printing paper and negative are held in close contact while being exposed) are made on a specially coated paper one side of which is 'light-sensitive'. This side is usually glossy, and the paper tends to curl Cover part of the sensi with this side inwards. tive (glossy) surface of the paper with some small object like a key or a Although it would be spoilt by exposure to coin and expose the paper to light, say, 5 seconds daylight and bright electric light, contact paper is at 2 feet from a 60 w. lamp. quite safe to handle in dim (shaded) electric light or yellow or orange light. Hold the object in position until you are back in the shade, then remove it and examine the In making prints there are four stages: Exposure paper.

Then as experience is gained he can try the more difficult negatives with the soft or contrast paper grades. Very little apparatus and only two chemicals are required-developer and fixer. The white borders round a print are obtained by You will need two dishes, one for the developing masking with black paper or special masks (such as solution and one for the fixer. A large basin of Johnson See-Thru Masks). clean water for rinsing the prints should also be obtained.
