Thanks! This helped me a lot.

science? engineering? and math? maybe im in the wrong major….

helped me out!

This video is awesome!!! Do you know of the math on flash photography?

Brian McKenna says:

So since the aperture is the focal distance divided by the diameter of the
iris, does a teleconverter technically divide your f-stop in half?

Tracy Norrell says:

Own a camera? You need to watch this…

If you’re a math geek you’ll love this.

Lukas Sprehn says:

For the people that don’t get the F-stop thing: just remember, the smaller
the number, the more light :P

Mika Kuitunen says:

I can’t remember how it was done in the film but one way to break the 180
degree rule without disturbing the audience is to take one shot from the
“safety line” or the imaginary line in your scene and then move to the
other side, or move the camera to the other side of the line during a shot.

OwwO it’s a cool way.

Thanks is fantastic video

Thanks great lesson. I would love to see how to set and adjust these on a

Goody Andy says:

good lord griffin, you were like a friggin wizard this episode. thanks for
your magical explanation, you gave a damn perfect unquestionable answer to
several questions.


254 shade of grey? I need to go talk to a certain writer about a certain
book! *storms off*

NorwegianVFX says:

Hi, I am currently thinking of buying a new camera, but I think I lack the
experience to get the best for my money. I have been looking at the new
Panasonic AG-AC90, and I must admitt it looks nice, but as I said I don’t
have the experience needed to tell for sure. Do you have any tips on good
cameras? I’m looking in the price range of $2000-$3500 :) and for some
reason I don’t want a DSLR.

Indy Mogul says:

It’s arriving today! I’ll talk about it on this Wednesday’s live show, and
probably do an in-depth look and comparison to the GH2 on Dec. 17.

veggiet2009 says:

Very good video, I like quick references for things. And that explanation
of f-stop was more thorough than I had researched on my own… I do have
one complaint, the video you linked to said “Dan Harmon talks about his
writing process” while it was a good video, very inspiring, he doesn’t talk
about his writing process that much, only a few minutes out of the entire
half hour video.

Ricardo Acosta says:

Isent’ it like askey art

kant0r says:

2:50 PACMAN o/ :D

exes9378 . says:

Why i am not disturb if the rule of 180 is not respected? In hunger game ,
at 10min , its not respected and its not disturb for me.

Half-Heart Films says:

Griffin will you ever come to Ireland!?

Indy Mogul says:

You’ll find an explanation of bitrates in my July 9 episode: “How-to:
Compress Video For YouTube / H.264 Explained.” Hope that helps!

Normal Hill says:

A very concise and informative episode. I really appreciated it. I’m glad I
subscribed. Thank you!

Phil Bolles says:

>>”That’s why it’s always written as a fraction.”<< Actually, it’s not always written as a fraction and shouldn’t be. An f-stop represents the *decimal simplification* of a ratio and should only be written as simply “f” plus the number, e.g. “f1.4″—–writing it as a fraction (f over stop) is incorrect and will confuse people.

Eric Tan says:

Can you please explain the difference between F-Stops and T-Stops

Indy Mogul says:

Not necessarily—just means you’re getting more motion blur in each frame
than the average cinematographer. Some people may not prefer the look, but
I don’t have a strong opinion about it. (Sometimes you simply need the
slower shutter to get a brighter image!)

Mitchell Lovell says:

As a cinema major and a math minor, the video is awesome for me!

Indy Mogul says:

You mean the Rule of Thirds? If you always place the subject’s eyes on the
top line, in a close-up, or a full-body shot, I think you’ll find the
framing usually looks pretty good! (Of course, for artistic reasons, you
may want to do something completely different, but it’s a good starting

Abdelmajid Zahmoul says:

for some cameras , when you bring the shutter speed up to 1/120s its gets
dark (and darker for 1/240…etc) what to do in this case ?

TittyTwisterBand says:

Fantastic, thanks really good info

Indy Mogul says:

Not as far as I can tell! (Is that why your username includes 3141?)

Dean Covert says:

254 Shades of Grey. I’m feeling a book should be published!

MuVariant says:

The “T” in T-Stop stands for transmission. An F-Stop is an independent
mathematical ratio that does not take into account the optical properties
of the lens’ themselves. A T-Stop is the F-Stop as actually measured from
that particular lens which accounts for how that lens actually transmits
light through it to the optical plane.
