I love to learn GREAT photography techniques from PhotoVision. They show photography Pros at work and in interview settings to get a better idea on how to prep for a shoot, marketing techniques, and post processing time savers. They currently have an AMAZING DISCOUNT: Receive PhotoVision's 6 DVDs for just $39 (originally $149) by using the promo code: PVFAN. We get DVDs bi-monthly, 2-hour photo and has a ton of info that I can easily apply to my work and save time. To find out more go to: http://bit.ly/PhotoVisionFan
Please feel free to add some sources you use to continually educate and refine your wedding (and other) photography skills.
