And I can agree with that, for the rare self motivated individuals who both know they have to do the work and have the discipline to see it through, and acknowledge that there's a lot out there they need to understand. But as I learned as high school teacher, just because you have trouble in the classroom, doesn't mean you'll flourish in an alternative (work at your own pace) classroom. The majority just slack off and drop out. But there are a few who end up doing post grad.
Training just increases your odds of being successful in the end and gets you there a lot faster. But there's still hope for those who have some kind of social limitation that keeps them from learning from other human beings.
There are some really bright people who don't understand, the fact that they are really smart, doesn't mean they can't learn anything from anyone. Some like to keep the learning anonymous. They don't want someone else to have the power to critique their work.
As a general rule if you want to learn something technical, you're better off getting someone to teach you how to do it. I think it's a mistake to think photography and other non lethal pursuits are different, just because no one dies if they are wrong. But then, if you just take pictures for yourself, and you think they are good, at least in photography never taking a course lets you live happily in that bubble, whether anyone else thinks you are any good or not. And for yourself, there's nothing wrong with that. Just don't post any youtube videos (like then tha tis the subject of this thread) showing everyone how little you understand.
Honestly, those dudes have no clue how ridiculous that video is. I have no doubt they are self taught. Someone learning photography who sees that video, doesn't see anything to tell them how to exploit the technology for the results they want. Not one thing. One of the disadvantages of being self taught is thinking all posted videos are equal in the value of their content. This one is just a waste of time. Anyone with any training will see that immediately.
This thread bing a case in point. Those of us who were trained and have taught are much more critical than the rank and file, Part of good training, is being able to see through useless information. I could come up with hundreds of optical science, lens design type facts that are not directly relevant to photogrpahic practice, and could design a 2 semester course designed to keep you from learning anything useful. This video would be part of it.
My whole focus from force of habit looking at videos is "does it teach anything useful in a way that will open up future learning." This video is anti-teaching. There is nothing in it that will increase your learning curve, and as with their last video, concepts are framed in away that closes the door on future progress. EG. it creates the illusion that you can't increase your DoF by using a smaller format. Something experienced photographers do all the time. it's made by the kid in your class who thumbs his nose at everything you do and then fails. Except in in the internet failure or non-failure depends on click bait, not knowledge. So you can both be an idiot and "succeed."
If this video was dependant on people actually knowledgeable and successful at teaching photgraphy buying it, well, they couldn't pay me to even download it. I'd seriously wish they'd paid me to watch the little bit i did, They owe me. I deserve to be paid just for giving them a very short audience.
And if they'd produced this video for my class, they would have about 5 pages explaining why they failed.
This video is one of the best reasons for avoiding being self taught I've ever encountered. It's anti-photography voodoo science encompassing no photogrphic technique or principles. For those conversant in optics, it's too simple to even be the point of a very short discussion. It's obvious.
No doubt it might be useful for bed ridden paraplegics with two camera bodies ( of different formats) and one (prime) lens.
Everyone else employs FL changes, zooming with their feet to achieve basic composition and framing making the whole video irrelevant.
