"Check with a spot-meter and squint." Great words to live by.

Geoff's eyes always seem to light up when he's talking about personal discoveries found through his journey in cinematography... nice to see when there are many others that seem they've lost that childlike excitement

I don’t know any film school in India that talks about this stuff. The information this man just gave is a treasure. All of his videos on Cooke optics channel are the best of YouTube in Cinematography.

Great information.. becoming a big Geoff Boyle fan. Appreciate his playful and pleasant demeanor and wealth of knowledge and experience.

Love the diffusion test at 1:28. Keep your eye on the right side of the frame and you’ll see different Tiffen filters being added to the lens to help soften the highlight roll off. Pro Mist, Pearl, etc.

Great stuff! Going out to buy a Burqa now! :D

[iiiiiiiiiiooooooouuu]

love this guy . tells how it is . no BS . hopefully will get to work with him one day :)

[randallburgess]

Awesome advise and perspective for us up and coming film makers. Thank you Geoff for your wisdom!

[Photographicelements]

I love this video! Geoff Boyle is awesome and tells you exactly what you need to know.

There's an irony here. The Camera used to record this video about dynamic range most likely has poor DR, the editor masked out the blown-out windows to try and draw the viewer's eye to Geoff, and as a result, I'm distracted by that mask, lol. :)

Anybody knows what year is this interview from? It seems like there were no HDR monitors around. I also still use my spot meter on set, but I usually combine it with waveform, although it's not 100% necessary. One argument in favor of waveform and false color, is that these alternatives measure what actually goes on in the sensor, instead of the lighting reflected by subjects ou objects in front of the camera. In film, we trust the manufacturer of film stock, for an expectable response to a certain level of lighting. Sensors don't behave like that.

[DaleRoossien]

amazing, Gotta get me a spot meter now.

[VilkanVisions]

I love this channel! So much knowledge :)

[RazorsRide]

What about the "controlled" grading rooms? Isn't light reflecting of the grader's face as well?

04:16 can someone please explain how one uses the Ansel Adams system with a spot meter in cinematography? I have a light meter too but just confused about integrating the Ansel system. How would I go about calculating what he’s talking about: “Mid gray is 5, caucasian skin the lit side is 6...”?? I cant seem to find any clear videos on this subject. I would greatly appreciate anyone explaining. Thx in advance ;)

Mom: Why are you painting your walls black?

[mahj]

The hell is happening with the windows? They're obviously overexposed, but they look like a dull grey.

[troyphillips]

What did we get from this ? Protect the highlights maybe, especially on the skin if shooting people .

[Tuernah]

Reason movies be shown in balck box theater be not for it be ideal view condition. It be for immersion. Ideal view condition accoradnace to occiptal lobe it be not darkens black room. The etechnology can be make for make two streams in capture one for raw next one for debayr in set live. The debayer in set may not be duplicato in completeion for this be effects on series of sensor sites accordnave for luminance levele in each sotes. However, it ccan be serve like comparison in post. Alhecvron may pervance as we goance further.

I love Geoff's extensive knowledge and experience, but often when I hear his interviews I get a feeling he is a man who like to listen to himself a bit much, don't you get that feeling?
