Excellent photography..............super presentation. Thanks for a good look at one of my favorite fall places.

Remember too, that it is condensation which is the most common cause of ‘water damage’ in laptops. Any item that is electrical should be allowed to warm up first if it has gotten very cold. If it contains printed circuit boards, the device should be placed in a plastic zip bag or something ‘before’ going out into the cold. Another piece of trivia: If you have noticed, some telephoto lenses have a ‘white’ barrel. Charles mentions that the first few shots may not be sharp until the lens temperature equalises with the ambient. The new fluorite lenses have a different coefficient of expansion from the other glass optics in the lens, so the the effects of uneven temperatures is even more apparent - hence the white barrels. This is something to remember when alternating between full sun positions and shade. Even stepping out of an air conditioned 5* hotel room and on to the balcony can throw these new fluorite lenses off a touch. But oh boy are they good.

This is amazing thank you so much for posting this!

Hi Charles, thanks for sharing your passion and knowledge.

[@MikeJamesMedia]

Thank you, Charles. LOTs of great information in your presentation, and easy to watch, due to your relaxed style. And... Of course, the high quality of your work stands on it's own. Excellent!

Very nice presentation. We learned a lot from watching this video. Thank you.

I wish you guys would put the guest speaker in a small picture on the lower right corner. When he clicks to a new image and you stay on him, it's a bit irritating we don't get to see what he's talking about. You did it this way in a recent video and it works so much better. Please do them all that way.

[@garydietz8807]

I totally agree

[@robertelbert7588]

Very nice work.

[@ThePhotographyHobbyist]

Lots of great advice in here...and good humor ;-) Ignore the 'pixel police' (pixel peepers, whatever you want to call them) as Charles suggests.

[@poppyspix4444]

Gee B&H - what's the deal with the cameraman/editor? Half the lecture is pictures and you don't show us the images?. Thanks a lot!

[@paulsparkes5741]

great talk just need to save up to come over from Spain !!!

[@garyjoe9226]

Good stuff, makes exposure seem easy!

[@Higgins_Nature_Photographer]

Great presentation, but it would have been better if the person handling the camera would show the photos the presenter was talking about, we can here the person talking, we don't need to see them all the time!

[@johnsholian4318]

Very informative and entertaining but like a lot of the other viewers, I wanted to throttle the camera operator. Don’t get me wrong, Charles is fun to focus on because he’s expressive but I want to see what he’s referring to onscreen.

[@tarjei99]

What is wrong with a bin liner to keep condensation away?

[@untouchable360x]

Winter is coming

[@norm7257]

Winter exposure is easy - use manual exposure and take a meter reading off a grey card.

[@seantomlinson3320]

Stop showing us the photographer.

if i ever heard more full of crock guy , jackets , all he does is pay tickets for wild parks , gets his little telescope and fills a frame with feeding animals , you can do it worse only if you miss the focus , which is hard to to on F20, truth be told i did see one F10 pic , he is suppose to be selling Fast Telephotos , but all his shots are F10+ , so slow some are even HDR, then all i need is Sensor Cleaning since F10 will shot dust on Sensor , not a new lens or Camera , those guys that stick with their Kit lenses these days are smarter consumers . Took me 5 lenses to learn
