......I have been called many times.... about many things.But I have been amazed at how little I really know about subjects that interest me, like photography. It was only when Carl Tyler made a comment about taking a photograph of the lunar eclipse & that he didn't have a fancy camera like his brother.. how he didn't understand f stop values etc that I realised I don't know them 100% either, I know how to use the equipment & what the values translate into when using the kit, but where they come from or how they are derived - no idea. Until now.....
Excellent easy to understand articles on lens apertures, focal length, lens speed and a whole host of other photography subjects can be found using these links from the Canon Professional Network Infobank website.
