Exposure matched would be good too. It's good to know the light loss, but we'd be properly exposing and we can then see just the light wrap differences visually.

@EverythingFilmmaking Год назад

Exactly

@_burd Год назад

Yea was just about to comment this. The difference in material is desired more for the shadow/specular quality changes than the exposure.

this was my thought watching this

@TheHRHM 6 лет назад

Maybe next time you could match the exposures of the diffusions. That would have been a useful portion to this video.

@GripTips 6 лет назад

The H.R.H.M eh, one day at a time as they say ☺️

@SuperAthleteTraining 6 лет назад

please do this! because this will really show the difference in look. the loss in exposure is just a problem that we must know about butt it is not the look that the diffusion makes. :D

@micah_clemente 4 года назад

Or if matching exposure for each is too much, you could just show the waveform/RGB parade for each so anyone can see the differences, no matter what screen they're watching on.

@dslrvideoshooter 6 лет назад

Solid stuff! Thank you for taking the time to test it all.

@GripTips 6 лет назад

DSLR Video Shooter you asked! Haha. Thanks man

@Shiznaft1 6 лет назад

Every video you put up is like a mini film school course. I really appreciate you taking the time to put up such wonderful and helpful content.

@liquidmocofilmsllc4915 4 года назад

This is one of the best channels for what I do... there are a lot of channels that go over lighting but not in depth like this. This is exactly what I need!! Thanks guys! Suscribed!

@kimsargenius4112 6 лет назад

Great comparisons, thanks for putting this together! Re: the distance of the source, next time you play with this, have a look at the rag from the subject side - the more you back off the light fixture the less you’ll ‘see’ the source through the rag

@AwesomeShotStudios 6 лет назад

Very helpful information here. Keep 'em coming!

@timrober75 6 лет назад

Thanks for doing this Dave... really useful! Thanks for all you do :)

@TheZaco32 6 лет назад

This is great! Is be interested in seeing the difference in the grids!

@RodrigoObregonubidia 6 лет назад

Nice work, thanks

@CinematografiacomoDurso 6 лет назад

great job dude !!!

@DigitalVibrant 6 лет назад

Thanks for the video! Do you think you can make an episode on rigging cars for lights and cameras?

@KevinStCroix 5 лет назад

1/2 grid is cinematic. At least with the exposure settings.

@soulfetish 6 лет назад

Nice long episode. Great stuff.

@GripTips 6 лет назад

Frank Nicoletti you’re welcome ☺️

@adambelanger 6 лет назад

Great video! In the future, a video showing the changes when moving the diffusion closer and further from the subject would be informative too!

@CalHallows 6 лет назад

Assuming even illumination of the whole sheet of diff then you're making the source larger in relation to the subject, as well as increasing the intensity of the light on its subject due to the inverse square law. Generally speaking it means that you'll be able to get a bit more wrap around the subject the closer the diff is, however you will get more harsh hot spots of highlight on your subject if you're using thinner diffs (250 vs. 216 for instance)

@victorfilm_ 5 лет назад

I just discovered your channel. Awesome info!

@keatonloudamy9160 6 лет назад

Can you test 8x8 diff. Like full grid, half grid, quarter grid, china, muslin/or bleached mus and whatever else is common in the industry

@GripTips 6 лет назад

Keaton Loudamy when I was making this I thought about a cloth episode so it’s definitely a plan. Soon enough I will

@honest_noise 6 лет назад

Yea, I'm stoked for this. Maybe the difference between an 8x8 ultra bounce and bleached and unbleached muslin.

@f.jacobalvaradoDOP 5 лет назад

^^Second this. Would really like to see a database of materials & images of the look when shooting & bouncing through these different diff materials. If anyone has any sites like this please comment below.

@benunantha7438 9 месяцев назад

Could you please explain the difference between spotted and full flood....

@branhasknowidea 6 лет назад

LEE has a free Diffusion Comparator (with Arri lights) app with videos and if you're using Arri lights, the Photometrics app is pretty fantastic to nerd out too.

@GripTips 6 лет назад

Brandomonium Pictures oh yea, I already have it. It’s pretty awesome

@branhasknowidea 6 лет назад

oh, and spoiler's for your next grid video. To my knowledge, or what I've been told/in my experience, the tightness of the grid pattern, or how heavy/light the grid is, increases/decreases the directionality of the light.

@gaffgripman9010 6 лет назад

Nice video. Would you have any interest in a ‘bounce material’ video? (muslin, ultrabounce, foam board, beadboard, etc.)

@GripTips 6 лет назад

Gaff Gripman that’s a good idea actually, thanks man!

@gaffgripman9010 6 лет назад

Grip Tips not a problem, I was also curious if you’re checking out cine gear this year.

@GripTips 6 лет назад

Gaff Gripman would love to but I don’t really have the cash for it right now

@J-Gx 6 лет назад

We always use 216, but looking at this 250 seems to be the winner!

@2315MARCO 6 лет назад

I always saw Lee Filters on set, these comparisons does demonstrate it capabilities

@gadusersko0071 5 лет назад

Would really like to see a database of materials & images of the look when shooting & bouncing through these different diff materials including ultrabounce, muslin bleached & unbleached, etc. If anyone has any sites like this please comment below.

@clivebrincat88 Год назад

How the heck could really appreciate and evaluate the light quality when you did not expose accordingly for each and every diffusion?

@mjmbk 6 лет назад

👍👍👍

@moomoochacoo Год назад

I can see why 250 is used so much

@DefiantFilmsTV 6 лет назад

Weheeey! You listened! :D

@GripTips 6 лет назад

Defiant Films ☺️🤘🏻

@DefiantFilmsTV 6 лет назад

Thank you so much for spending the time to do this for all of us, it's great to see! Any chance of a cloth comparison sometime in the future? **puppy-eyes**

@josephboldt8065 6 лет назад

I'm going to watch again in case I missed it, but how far is the diffusion from the subject?

@hozhenjie6755 6 лет назад

To be fair this wasn't an exposure test.....

@GripTips 6 лет назад

2-4 ft, then 6-8 feet

@josephboldt8065 6 лет назад

Looking forward to an understanding about the difference between grid and just diffusion. I'm coming to this from the stills side, and I've never seen someone explain what grid cloth does different. Keep up the good work.
