Here are some great tutorials about wedding photography. They are done by Becker and it’s in video which I don’t usually like because I can read way faster than a video plays but he has some really good tips for beginners and intermediate photographers as well about workflow and marketing and networking and almost everything about wedding photography. Best of all, it’s free!

I’ve just also recently discovered Actions in Photoshop. A lot of wedding photographers use Kubota Actions by Kevin Kubota as well as Totally Rad Actions by the Boutwells to make their photos POP! Here is Becker’s post about actions.
