Videomaker – Learn video production and editing, camera reviews › Forums › General › Video and Film Discussion › Two resources for videographers
Here are two excellet web sites which I have found extremely useful. Both are maintained by video and film professionals.
Walter Graff's site — http://www.bluesky-web.com — has a wealth of information in the section called "Purchase/Learn." Not sure why the Purchase part is in the title as there is nothing there to buy on the entire site. Here you learn a great deal about lighting and other aspects of production.
Ron Dexter's http://www.rondexter.com contains short articles based on Ron's experience of decades in the business. It's folksy, funky and very informative.
A third resource is called Cambridge in Colour, a British site: https://www.cambridgeincolour.com/
Although this site is specifically aimed at still photography, much of the information — especially in the Tutorials section — will be of great interest and value to videographers as it deals with lens, depth-of-field, color, etc., issues that are a part of any graphical depiction.
