I have to shoot a big award show next week and have to take some "red carpet pictures". I have a lot of experience taking event pictures etc. but I have never done portraits or used light boxes or any other lights. I guess I need some good light for the red carpet set-up and found some cheap softboxes - 2 for 100$. They have a temperature of 6500 kelvin - is this a good solution? Should I invest in more expensive lightboxes where I have more control over the temperature?
