Projected Digital Imaging


Projected Digital Imaging - often shortened to PDI - covers the many uses of digital image projectors, especially for showing photographs in WGPS.

We use PDI in competitions, both within the club and in inter-club events. We also use projection to support some speakers, and in some Friday Critique evenings. Many external competitions also use PDI.

Printing these Notes

if you need a printed copy of any of these practical notes (to help you at the coal face, for example) use the PRINT button that you'll find at the foot of each page.

This opens a new window without any of the stuff (side bars, navigation features, etc.) surrounding the page contents. Then use PRINT THE PAGE at the top of the window.

Acrobat Reader Versions

At the foot of some of these pages you'll find a red PDF icon alongside a link to an Adobe Acrobat PDF file. Click on the link - not the icon - to open in a new window with the Acrobat version. Then you can print this window to get a really pretty copy. (Directly downloading the link using right-click does not seem to work in Wikidot, unfortunately.) Use the browser back button to return.
