From time-to-time, we'll add PDF files here from those who are kind enough to produce them. They'll be on a variety of subjects but will especially lean toward photographic techniques.
Whilst they are freely downloadable, they are for personal use only. Please respect copyright and if you want to use anything, please contact YPS or the author to ask permission.
This will also be the place where we add links to external websites that we feel may be of benefit to YPS members. As they're external sites, YPS can take no responsibility for content.
The first PDF has been supplied by Russell Watkins. It is the presentation that he gave on basic flash photography at YPS on October 22nd, 2014. He has also added some material that he hopes you will find useful.
If you're interested in macro-photography, especially of the extreme variety, Johan Ingles-Le Nobel's site is worth a look.
