@ 34:57 this is called a "rocket blower", as in some models it looks like a bomb from WW1 with a grease nozzel at one end, and the 'fins' allow it to stand on a table, etc. and one point about compressed air, the oil thing is correct, as mechanics have a cleaner/lubricator on the line for air grinders/rattle guns, to lube them; if you use one, make it a small one, say used for airbrushing, no oil; but the main point is LOW PRESSURE, with 90+ PSI on the line, you can blow things into and also dammage the digital sensors, or the ir etc. filter gels/glass in front of the sensor block, cracking or scratching it!! (that is why in photography still studio's they prefer the rocket blower to pressurised air). one other point, if you use 'canned air' some people may think it is OXYGEN, and pipe in liquid Oxy instead of room 'air' and crack the lens that way (cryogenic properties of storage of this pressurised gas).
This guy a s a really good instructor. He knows his stuff and is good at explaining it.
Very good video would like to see more Fantastic Teacher you have learn as much from him as you can !
