I'm a novice photographer. I own a Canon EOS 100D and want to take a picture like this one of myself.
Apart from a tripod, remote controller, tether cable, and a laptop, what else do I need to set up a scene exactly like this one?
This is very easily achievable with just natural window light from the left and a big white reflector on the right. The window can be replaced with one softbox of a minimum size of 60cmx40cm. This will give you the larger catch light in the eyes to the left and the smaller to the right.
I'd go with a three light setup. One for the background, however complex you want it to be, a bare bulb can be enough, but if you want a completely linear transition you need to try out a bit.
For the main light you'd need a softbox of similar lightformer, find direct lighting comparisons here:
You can use a third light to lift up the shadows or maybe a reflector can do the job.
