CHOOSING THE FILM
SLIDE OR PRINT ?
Colour is far and away the principal medium of photography , but there remains a major choice within it . The form of the final image can be either a slide or a print , and what you do with either can itself vary , as we will see later in the book . For most people , this means either projecting the photograph in a slide show , on a screen in a darkened room or in a projection box , or displaying a print on a wall or in an album .
In making some sense of the enormous variety of colour films available - there are many different types from different manufacturers - the first step is to settle on an end - product . Although it is possible to shoot both prints and slides ( alternating , perhaps , or having a second camera body to allow an on- the - spot choice ) most people tend to stick with one or the other .
If you are undecided , consider the pros and cons of each . A print is the natural way of looking at any picture - it can be seen in normal lighting con- ditions , and is tangible . It can be mounted , framed , hung on a wall , placed in an album , or passed from hand to hand . Getting faithful colour reproduction and a full range of tones , however , takes time and skill ( this , on the other hand , is part of the attraction of colour printing for many people ) .
One of the great advantages of slides is that , being projected by a bright light source , they appear to have considerable ' punch ' brighter highlights and a more immediate visual impact than a print . The process of photography with slide film is also simpler . As soon as it is processed , the film is ready for viewing . On the down - side , slides are not so convenient to look at . For their best effect , they need certain viewing conditions : principally , dark surroundings and a good , purpose - built screen . A slide show often has the nature of a perform- ance , a disadvantage for some , but desirable to others in the sense of occasion that it can lend to the images .
One further point is worth considering . When photographs are reproduced in magazines , books and other print media ( the term is photomechanical repro- duction ) , the original images are usually in the form of a transparency , not a print . For professionals this is usually the overriding consideration , but there is also a growing number of amateur photographers who sell their pictures .
Mounting a print
1. Measure the picture area that is to appear when mounted , and mark the frame lines on the borders of the print in pencil .
2. Mark these dimensions on the back of a sheet of thick card , and , using an angled mat cutter cut each of the lines up to the corners . Trim with a scalpel .
3. On a second sheet of card - the backing for the mount - position the print and mark round the corners in pencil .
4. Having sprayed or brushed a light , even covering of glue onto the back of the print , roll it down onto the backing card using a sheet of tracing paper to avoid making marks .
5. Apply glue to the edges of the backing card , position the top piece of card , and press down firmly .
6. The mounted print is ready for display , but handle it carefully until the glue is completely dry .
ABOVE There are two standard designs of 35mm slide projector ; the revolving drum type magazine ( such as this Kodak Carousel ) , and the sliding tray type .
Mounting and labelling transparencies
Make sure , above all , that transparencies are adequately protected and properly identified . Develop a system for logging in transparencies , stamping your name , copyright mark , date and description on them . If a publisher uses a transparency for reproduction - many amateur photographers are now finding outlets for their work - it will have to be removed from the mount , so be prepared to re - mount used transparencies .
Card mount ( BELOW ) . Plastic mount ( RIGHT )
A convenient filing system is to use transparent sheets , each containing individual pouches . These will fit into a standard filing cabinet .
A red spot in the lower left - hand corner of the mount ( BELOW ) facilitates assembly for projection . To signify a sequence , rule a diagonal line ( RIGHT ) across the edges .
