The image at 5:14 is the winner. It’s much better than the final image in my opinion.

I think the image at 5:08 is much more pleasing to look at than the final version. Great, straightforward tutorial regardless.

Wish i had a huge indoor space to practice lighting, that would be so much fun.

Excellent teaching. Thank you. Never would I have placed the light on the backdrop like that. I appreciate the details.

I have watched dozens of tutorials on lighting and this is the first one that really explained how light works. Just telling where lights go gives other's no lesson or knowledge, but this taught me so much about how to use light in a studio. Thank you for your work in making this video

Well that tutorial escalated quickly

For an education brand as popular as Fstoppers, I’m surprised they got the inverse square law wrong at the beginning. Go back and fix it so you don’t mess up newbies who are learning.

Great contents. To the point with each variation of lightning shown to demonstrate the differences visually! Separating background and the subject is so important after I watch this.

This is a great lighting tutorial...bravo!!

This was sooo helpful! Thanks so much!

Great video David. Nice and straight forward.

Such a great refresher

We need these kind of content!

Great video. That last image was awesome.

Great video. Very easy to understand. Thank you for the tips!

Great, concise, simple tutorial.

Just what I was in need! Thaks guys

Fantastic video. Easy to understand. Wish I had seen something like this years ago!

This is next level education for us beginners. I don't do a lot of portrait photography, but this is gold.

This is so perfect love this thank you for this

Excellent tutorial!

Great tutorial! You look and dress just like I did in the 90's - what a stunner!

An excellent article! Thanking you so much!

This was a fantastic tutorial!

Great Explanation

Generally a good video. However the explanation of the 'Inverse Square Law" (at 1:08) is not correct... Doubling the distance between the light an subject decreases the light to 1/4 (2 Stops), and not 1/2 (one stop) as stated in this video. This is also explained incorrectly (at 1:30)... If subject is at 4 feet from light and backdrop is 4 feet from subject (background at 8 feet from light), the background will be 2 stops (not one stop) lower than the subject. One technique that I have used for some time now (and I have never seen explained in any KZfaq Video, and requires no math) is to use the 'standard F-Stops', 1, 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22... and 'convert this to feet' when using a single light source like a strobe. For example, if subject is at 4 feet from light and background is at 8 feet from light, then background will be 2 stops underexposed (4ft -> 5,6ft -> 8ft). If you really want background to be 1 stop less, then place subject at 4 feet from light and background at 5.6 feet from light (1.6 feet back of subject). Practical examples: If you have space limitations and want 2 stops background underexposed, then place subject at 2 feet and background at 4 feet (2ft -> ft2.8 -> 4ft). Of course, this brings other types of issues like fast light fall off in subject is illuminated from above). If you want to reduce the light falloff between subjects (for example in a group photo), then place the subjects as far away from light as practical. For example, in a group photo with a single light... Placing subjects between 11 and 16 feet (11-16=5 feet distance front-back between subjects) then all subjects will be within 1 stop (f11->f16). If same group was placed at 8 feet then to maintain the same one stop drop, then the back subjects cannot be more than 11 feet from light source (allows for only 3 feet of separation 11-8=3 (f8->f11) between front-back as compared to 16-11=5 feet in the previous example). If a group is standing 'in-line' that has a lot of depth distance, place the light away from camera. For example to the right of camera so light between light source and subjects are basically at the same distance then all subjects will be exposed about the same.

Excellent tutorial. Thank you

Nicely done and explained extremely well

Wow. This video is great. I've learned so much. Thanks.

Awesome video, very helpful. Thank you.

Thank you for this :)

Thank you. This was a great step by step video. Learn so much

Hope the first of many! I was, ok, ok, ok and then ending 🤩🤩🤩 the photo looks epic!

Great video. Love the details...

Love this guy

Thank you so much for making a video on back drop lighting they are so hard to find. Please make more. PS I like the Ponytail 😏

Great Job!

Awesome Tip 🙌🏾

Great video! Thanks for sharing

WE MADE A MISTAKE!!! The inverse square law states that you lose 75% of your light as distance doubles (not 50%). To better understand the inverse square law, check out this video we created with Peter Hurley: kzfaq.info/get/bejne/rrVdfZdju7OYZGw.html

Good to see David in front after seeing him for many years assisting 😊👌🏻

cool tips. great job

So helpful ❤

Great tutorial!

this is a great video and great explanations with examples. well done!!!

I've been doing outdoor photography for over fifty years. Going indoors ! thank you

Wowwwwwww that was freaking great

Amazing 😻 thank u

There has been a confusion with the explanation of the distance/light rule: Physics has explained that the intensity of the light fades in a square factor In relation to the distance between the source and the measured point. Therefore, if you multiply your distance by 2 you will divide the light you get by 4. (Not 2 as it was said) Great content. Sorry for any English mistakes.

Best video ever

A GH5, was NOT expecting that. Awesome pictures man!

this is amazing

Good content 👍learned a few things thanks

Great! Thanx

you have such a good subject 👍🏻

Thank you

This video might be 4 years old but it is a tremendous help for us

When watching it stoned and he throws technical stuff at you...come on man, I thought we were friends!

good for practice

Thanks

The 2nd to last was the best

Wow what a video man! Best explanation about lighting so far.

My fav image at 5:12 . Thanks for the nice video.

வீடியோ மிகவும் பயனுள்ளதாக இருந்தது மிக்க நன்றி இரா.மனோகர் சென்னை . Very useful This video sir, , big thank you sir R.MANOHAR ,Chennai.India

Came here to learn how to do things with two lights.. now I realized I need six..😔

Great video and presentation. Clear and easy to understand, well done!

Nice video! The result with the modifier is stunning. I searched for the profoto backlight. It's over 2000$ 😅

thanks

The ending went from zero to 100 real quick 😂

Nice video

Almost everyone gets these inverse square law tutorials wrong almost all the time. While there are issues with the math this time, the (most common) mistake is changing multiple variables and attributing the resulting changes to "light falloff." At 2:29, the backdrop exposure is what it is...if Matt were to move forward towards the light, and NO OTHER CHANGES were made, the backdrop would expose exactly the same as the previous photo. The error here was at 2:49 when Matt walks closer to the light AND "we drop our exposure to compensate." The resulting photo has a darker backdrop because "we drop our exposure to compensate" which is changing an exposure variable that has nothing to do with the placement of the model or the inverse square law. If, following the initial photo of Matt just in front of the backdrop, you "dropped the exposure" the background and model would both be darker...argh! I promise, if you put the camera on a tripod and took a single picture as a baseline, then moved the model closer and farther to the light then did not change strobe power, exposure or any other variables the backdrop would expose the same every single time. The model's look would change, but that's just because he's moving closer or farther from the light. The inverse square law applies to more than just photography...it applies to all manner of energy like light, sound, radiation etc. But, you can't change multiple variables. The important and informative elements of this tutorial regarding light placement, changing light positions and all the good stuff is lost because of the basic errors at the beginning.

Thank you excellent video!!; Could you tell me which lens you used for the photos and what camera did you record the video?, greetings from Mexico

Where did this guy come from? He is such a great teacher. Use him More please.

where you buy the grid from you placed on light/. thanks

If am not not mistaken, the inverse square laws means that if you double the distance the power is one quarter as strong. (1/(2)^2=1/4)

Both the model and the photographer are hot 🔥 Great video

How would you light the background to create a gradient effect going from darker to lighter from the top to the bottom of the frame? Anyone know? Thanks!

Handsome model❤️

1:18 hmmm..🤔 but as fas as I know, the intensity that you lose when you double the distance from the sobject to the light source is a 75% less, and not "by a half" (50%), so there you have to deal with the fall off of the light, that happens when the light is too close tto the subjetc... or am I wrong? 🤔

What if I use white background and I switch it in PS in post?

Good love David using the GH5. Oldish camera, that still mind blowing in terms of video. ✅ Well, off to watch the video... popcorn is ready !

Is it possible relight the 1:51 to the 5:14, just by using photoshop

Cool. Except a white or dark gray background would have been a better comparison on making the white more gray or the gray more white in the adjustments.

Easy shoot RAW 😁

Surely the inverse square law means if you double the distance you quarter the power. (As in physics etc).

voooaaa😍

sir, please mention camera settings also in image

Does this work with colored light on the back drop? 🤔 I want to buy a colored light to use in my back drop with a halo light on me for filming videos? I don't know anything about this or the language used lol so hope that made sense

dam, I've owned 2 GH5 for like 3years now and may have accidentally took a picture once or twice but never even thought of doing an actually portrait shoot with them...huh, who knew

What is the size of the backdrop used here?

David, or somebody... a question about the diffusion fabric we put in softboxes, please. And I'm sorry my English. I'll try my best. A friend of mine has a broncolor kit system with some stripboxes, reflectors and square soft boxes. The diffuser fabric has fold marks and I really hate those marks because I use that equipment for product photography. Specially when I shot wine bottles. If you store your softboxes, how do you fold this diffusion part? I mean, the white fabric part. I just want to know it because I hope in a near future I could buy my own equipment. Thanks guys

Going from basic to advanced in a short time. Great tutorial

А если комната 2*3 метра, как отрезать фон от света?)

Work in triples. If you triple the distance, you get 1/9th the amount of light. eg. Instead of 2ft from the subject you move the lightsource to 6ft from the subject (3x as far), you'll have only 1/9th the light falling on the subject. Should give you an idea of just how big and bright the sun is given that it's a long way away! And how much stronger your light has to be dialed up to expect the same exposure.

how to use studios strobes ailon with camera settings

does the light that is on the backdrop stay on constant or is it flash? If its flash is it possible to get the same look if its constant?

👌

Dang it... Now I gotta buy strobes 😂😂🤣🤣

What are the settings used on camera?
