WHAT WILL YOU NEED FOR THE PRACTICE?
You need light sources! When I started my light training, I didn't have the money to work with expensive equipments, so I used the cheapest lighting sources for my videos. I offer you three solutions to this question.
1. The first, if you have the opportunity, use all possible and available light sources that your budget allows. We are talking about the rental of lighting sources and grip system.
2. The second way is to get some of the cheapest 500-1000W tungsten "halogen work light" with dimmer. This power will be enough to work on medium and wide shots.
3. The third way is buying a lighting source. And here I can advise you very cool LED sources of the Apurture, Godox, Nanlite brands.
Also, you can practice all materials with natural light sources. The sun is very cool and free light source.
For practical examples of this course, I use devices such as: ACE 650W, Godox 300VL, Godox 150W, Arri 1200w
