A friend of mine asked me to do a photoshoot for a calendar for his hair saloon. And i think the accent of the shoot will be hair. I have never done something like this but i was thinking to do it like portrait shots just from odd angles to make the hair stand out. I have 1 external flash with a softbox would i need more? And what kind of background should i go for? The lenses i have are in my signature. Should i borrow other ones? Any advice will be appreciated.
