Been creating still images for the ad world for some time now.
What "merit" do you need more than what he is clearly showing in his videos unless you have your eyes closed. He is talking about the usability of small LED lights with cameras that can shoot cleanly at high ISOs, not advanced cinematography techniques. Caleb is hitting the mark exactly where his target is. Cinematographer snobs can look elsewhere if they require seeing a polished reel from a presenter before actually looking at what is being presented.
The top three most popular camera brands were used on 155 films out of 244 films total (that reported their data). That leaves approximately 89 films or well over 1/3 of films that were shot on something else. To not mention the mix what nearly 1/3 of what the other films were shot with, seems like a big omission to me. Over 1/3 is a significant chunk. The Arri Alexa is undeniably a beautifully performing camera, but its price, even at rental, puts it well out of the range for many independent filmmakers with minimal funding, which is the group I actually thought was the target audience of No Film School. And to just list the brands of Canon and Sony as the second and third most popular CAMERAS is also a big omission. Knowing which exact cameras used from those brands would have been very useful or at least interesting information. Otherwise, it's a fine looking infographic.
I'm not a fan of using microfiber cloth on lenses, unless you toss it after the first use. If you use them more than one time, dirt removed from each prior cleaning is transferred back onto the lenses again which could cause abrasion. Instead, use lint free disposable Kimwipes. I've tried many fluid cleaners and the best lens cleaning solution by far is Pancro Lens cleaner. Kimwipes and Pancro is an unbeatable combination.
Never use a microfiber cloth on a lens as shown above unless you're planning on throwing the cloth away which sort of misses the point of using a cloth in the first place. The cloth will trap dirt particles that you don't want to reintroduce to other lenses or back onto the same lens. Peter actually uses the same cloth that he shows as being filled with dirt! This is a real no no! Instead use disposable Kimwipes from Kimtech. I have tried nearly all of the commercially available lens cleaners and the Zeiss lens cleaner is cheap and is OKish, but Pancro $$ is absolutely the best lens cleaner for perfect results every time.
