Viewing transparencies
As soon as your transparencies are pro cessed , you will want to view them to assess their worth . A hand slide viewer is a cheap way of quickly previewing slides , but it is not convenient for showing slides to several people at the same time . Models which run off electricity give a better quality image than battery - operated viewers , although the latter can be useful in remote areas where there is no electricity .
Slides in plastic or cardboard mounts can be assessed by projecting them one at a time in a non - automatic model , or by preloading the whole film into a magazine for use in an automatic projector . Viewing slides with a slide viewer or a projector I will show whether or not each frame is correctly exposed and sharply focused . Try to be hard - hearted and reject incor rectly exposed or unsharp slides ( unless an image was deliberately defocused ) they will not improve with keeping . Neither a viewer nor a projector will enable you to compare consecutive expo sures where you may have varied the lighting or background . The best way of making a critical comparison between different exposures or magnifications is to lay the whole film on a light box and view it with a x10 magnifier , indeed this is the only way you can view unmounted transparencies . I examine all my films on a light box , checking for emulsion scratches or other processing faults . Such frames immediately get banished to the trash can . I also use light boxes for selecting " pictures to send to clients and for check ing used transparencies.
The way in which you choose to view your slides is likely to be determined by the way you store them and the number you take . For instance , if you keep them in their processing boxes it is easy to place them in a slide viewer with a gravity - fed magazine . Transparencies can be stored in projector magazines , al though these will take up much more space than a slide box or flat PVC . pocketed sheets . Once your transparency collection extends to a few thousand slides , you will need to adopt some method of cataloging . PVC pocketed sheets can be labeled at the top . A
Slide viewer
This battery - operated viewer has a large bright screen for viewing 35mm transparencies at three times the original film size . The slides are inserted one at a time into the viewer , which can either be held in the hand or placed on a table . When the fold - away foot pulled out , the viewer can be tilted for easy viewing on a flat surface .
Slide viewer with magnifier
This model has a magazine into which 20 to 30 slides ( depending on the thickness of the mount ) can be loaded . The retractable magnifier doubles the magnification on the x3 screen image .
Ring binder
A ring binder is a useful method of storing limited numbers of slides in clear PVC pocketed sheets with punched holes . Each of these sheets holds twenty 35mm slides , and can be removed for viewing on a light box . Small slide collections can be stored in ring binders .
Hanging sheet
Each pocketed PVC sheet is filed vertically in a conventional filing cabinet . suspended from a metal bar which slides through the top of the sheet . One sheet holds twenty 35mm slides .
system based on ring binder files will be much cheaper than a filing cabinet which houses suspending vertical filing sheets , although over 5000 slides can be stored in a single cabinet drawer . A portable case is a useful way of storing and carry ing up to 1000 slides in hanging sheets .
a When transparency collection reaches a size which makes it commer cially viable to run as a photo library , then each transparency must be cross - refer enced so that it can be quickly retrieved . It is also important that the best images can be viewed by any client at a moment's notice , so that a large capacity slide cabinet , with a built - in light box . is essential . The one illustrated here is part of the integrated Multiplex System 4000 . The compact design makes it especially attractive for use where space is limited . Many other designs are available , includ ing Abodia cabinets which house 5000 or 10,000 slides .
Sound - slide projector Transparencies can be viewed with this projector either on the built - in screen , or an external screen . The slides are automatically advanced in response to pulses on the tape , so a sound - slide show can be run with an unattended projector .
Automatic projector
With an automatic projector . slides can be pre - loaded into a magazine ready for use at the touch of a button and they can be changed and focused by a remote control extension lead .
Slide cabinet
This compact cabinet stores up to 3960 35mm slides , 120 of which can be viewed together on one of the slide - holding frames . Each frame is viewed against a built - in light box which , like the frames , is pulled out of the cabinet for use.
Tilting light box
This light box has a tilt - top which adjusts up to 12 ° from the horizontal for convenient viewing and for sorting slides while sitting .
