There are just less than 7 weeks left to submit your behind the scenes contest video. Submissions are starting to come in and it's amazing what our readers are doing through their photography. As the video submissions come in we are going to feature the standouts here on the front of Fstoppers. In Zach Hetrick's behind the scenes video, he shows how he created commercial sports portraits of The Hoosiers's track and field team. Zach takes some time at the beginning to talk a bit about the lighting setup he used and shows how you can give your group shots a punch with some nice light thanks to a few Alien Bee monoblocks. Leave your comments below if you have any questions about this shoot or simply want to give some friendly support to Zach. You can check out all the entries on the BTS Contest Forum Thread, and remember to get your submissions in early so we can share your work on the front of the site.
