It can be a little daunting when the shooting location itself is a large cavernous space where you have to light using your small flashes. It's all the more difficult when you have to kill the general ambient but yet maintaining just some traces of existing hot light sources (e.g. table lamp, down lights) for mood.
Check out my recent shoot at Rentwise's warehouse on how I shaped my ambient lighting with small flashes.
I'm currently involved with the management of Rentwise's branding exercise and am responsible for some writeup and photography works of their operations.
That includes taking pictures and sprucing up their staff's blog posts and quarterly newsletters which make up the many voices of Rentwise's IT rental business.
