This is an excerpt from the photo seminar I gave at Wonderfest this year, Filmy's Foto Fantastic. I don't use a photo tent, but a lot of people asked me how to build one, so I put this little tutorial together. Note that a photo tent will not make you a great photographer. It WILL diffuse the light and give you a more even effect for your photos, but it is not the cure-all for model photography.
The main thing you need for good photos is an understanding of the basics - aperture, shutter speed, lighting, and depth of field. FOr more information, check out the slides from my seminar in the Filmy's Foto Fantastic tutorial.
