Please do not rush out to buy lights... natural light is always the best.
Go into your local camera store and put your camera on any gitzo carbon X6 tripod, just check out the shake, it should not shake. A ball head is quick and easy.
Go buy or steal your own shower curtain. Push pins work.
you can always raise your ISO if the light get too low.
Are you a Los Angeles local? I ask because you can look at Samy's camera and buy from BH to save the tax.

For me any low light situation, gives the viewer more to imagine

Too many ways to do Boudoir Photos. I put a white shower curtain over a window and let the diffused light fall on the subject.

thank you.

I agree with everything you said, and I always have my camera with me. When you open the Raw where do you store to create a Tiff? are you mac or pc

if you are shooting in RAW (NEF)... DOWNLOAD to and external drive then into lightroom or photoshop
