Go into Page Setup or Presentation Setup and check that 35mm format is used. Programs often default to other sizes, Powerpoint defaults to On-screen show which will result in an image that does not fill the 35mm frame. The Centre will not alter the Page Set-up as routine because of changes that may occur during this process. Make good use of the available space on a slide. Do not use small lettering with masses of space around it, but neither should you place text or objects too close to the edge of the frame - you may find that the slide mount cuts off lettering or information.
Slides have to be legible.
If you wish to use a non-standard font, check with us first that it is available on the computers. Keep text short and to the point. If you go over 30 words on a slide, a significant percentage of your audience will not read it. People read sentences in capital letters at about half the speed of lower case. A darker, saturated background works well, with lighter pastel colours for text and fills.
