We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.
Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.
be printed on another positive film to give the final projection copy.
As the film is so slow, we shall need more light or a larger stop.
On the other hand, it will not reproduce half tones easily. This means that the paper cuts will show much less (if at all) than with a film that reproduces subtle changes of tone. As we cannot use a range of tones in any case with the paper cutting method, this is no disadvantage.
We can also use colour film for photographing coloured drawings.
The films to use are Anscochrome (8 and 16 mm.) or Kodachrome (8 and 16 mm.). In either case we shall need the artificial light type, so as to obtain the best colour rendering. Both Anscochrome Tungsten film and Kodachrome Type A film are balanced for Photofloods.
With any other light source we shall need suitable colour correction filters in front of the camera lens. These are obtainable from the makers.
When shooting in colour, watch the following points.
Make sure the voltage of your electric mains which feeds the lamps is constant. Variations in voltage will affect the colour of the light sufficiently to change the colour balance of the final film. This will be very noticeable when the film is projected on the screen.
Shoot the whole film on one batch of colour stock. Different batches vary slightly in colour balance, which again may be annoying when the finished film is assembled.
For the same reason send all the film to be processed together.
So first choose the film, and load the camera with it. This is not an unnecessary hint. More than once a whole scene has been shot with no film in the camera! And if you do remember to load, don't forget to take the lens cap off!
Before starting to shoot, make a routine check of the camera. Always check the items in the same order and it will soon become a habit.
