I need some help with studio lighting. I am taking photographs of a friend's sculpture - various pieces of work. Anything from carved plastic, wood, stone and molded clay. I have been having issues with lighting the photographs just right.
I am using a Canon 30D with EF 100mm macro lens for the smaller stuff and my EF-S 17-55mm for the regular size stuff. Generally I've been shooting at ISO 125, f/7.1-9.0 @ 30 or 50. I am borrowing a lighting kit from where I work. It is really for video lighting but until I can afford some strobes, this is what I have to work with. I am using Lowel Omni lights, 1000 watts total. The pictures come out a bit underexposed and I have to raise the exposure in camera raw and do some tweaking with curves and levels to get them just right. I'd like to eliminate as much post-processing work as possible. Raising the ISO helps but adds noise. We are creating poster size prints of some of the photographs - 20x30 and 24x36 and I need images to be sharp and in focus without added noise.
I may be updating to a 6D soon, perhaps this will help improve my technique.
Here is my 'studio' setup. I am using black velveteen fabric that I purchased at a local fabric store. I am using plain old white bedding sheets to help soften the lights. I would appreciate any help with improving my technique. Much obliged!
