Negative example: I was looking into the German manual of my Canon EOS R5 II, and it is just fluff. Hundreds of pages, full of white space, telling me about features without actually explaining what they mean. Awful automatic translations. Their manuals used to be good (looking at my EOS 6D). But these days: oh boy.
At that moment I felt sorry for this company, very sorry. How can you have so much disrespect for your customers? Does anyone in the physical world talk like this or do you marketing guys want to be talked to in such terms?
Brutal.
I also wrote on what I think makes docs beautiful, by the way! https://passo.uno/what-makes-docs-beautiful/
But if you look how much manuals get ignored by the customer, it doesn’t make sense to put work into them.
It is much better to let a YouTuber do it, by lending them the product and throw small amount of money against them.
Manuals are just there for legal or certifications requirements these days.
