I've been using the Youngnuo LED lamp for the whole fake daylight series. Then, I started to work on the tutorial and realized that noone will buy a $60 lamp just to take some fake daylight shots. So I decided to try the same technique with a regular IKEA floor lamp. And it worked. It obviously requires longer exposure time and different white balance, but it works.
The tutorial is ready and scheduled to be published tomorrow. I hope you'll enjoy reading it as much as I did writing it.
