Photographer David Hobby has a phenomenal resource for off-camera lighting over at his site, Strobist.
If you haven’t had a chance to read through it, he has basically created a wonderful complete off-camera lighting course/tutorial on this site, Lighting 101 and 102. If you’ve ever considered working with off-camera lighting, this is a must-read series.
From the website:
Lighting 101 is the core foundation of Strobist. It is a free, start-from-zero tutorial that will teach you the basics of lighting and minimalist lighting gear. Lighting 101 will have you up and running in no time—and at minimal expense.
and
Lighting 102, currently under revision, is the sequel to Lighting 101. Where L101 was about gear and basic concepts, L102 will teach you how to further understand and control the qualities of your light to make it do your bidding.
For the first time in a long time, David has actually posted a great new post in Lighting 101, A Spin Around the Block, or trying out your umbrella, flash, wireless trigger for the first time…
Using just a single light, and simply moving it around, David helps show the myriad of feelings and results that can be had…
It can be a bit overwhelming sometimes when first trying this equipment out, he does a great job (as usual) coaxing folks to give it a try and see how things unfold. Well worth a read!
