The thing I appreciate the most is the direct approach. Nobody is trying to be cute, funny and entertaining.
You are kidding right. He is trying to be cute by being condescending to the model.
Every flash tutorial that I have watched explains why, and how, to use flash to freeze motion. This is the first time that I have heard someone explain that using a lower power setting on the flash unit actually does a better job of freezing the motion than using it at full power. Thanks, Pye.
First time i have heard this too. Glad someone else noticed
How many flash tutorials have you watched and what do they say ?
The lower power will reach its maximum intensity quicker because its lower but does that lower power emit enough light to expose your subject as intended ?
Fast duration powerful flash comes at a premium.
YES!!! Great explanation. Cleared up some misconceptions I’ve had about light and some language I’ve been using. 🙏🏽
No Way! I have been struggling to freeze subjects with flash and kept upping the power, now it finally makes sense! Thanks Pye!!!!
You can tell Pye is a master at his craft and a master at explaining his craft. Epic
This is great! Another great video from Adorama!!! Thank you!!!
Wow! Excellent info. Keep coming these one of a kind tutorials. Thanks!!!
Excellent information presented in an easy to understand format. Thanks!!!
A good point about the inverse square law is how it relates to the background. If the model is close the the background and you pull the light away, the amount of light coming back from the model is pretty much the same as what comes back from the background. If you start out with the model further away from the background and pull the light away, the reduction in light coming to the camera from the background is less the reduction in light coming off the model. When you readjust the exposure to compensate based on the light off the model, there will be more light coming off the background in the second scenario than in the first. There are other videos demonstrating this concept out there.
Gabrielle is such a patient and beautiful model. Adorama can be lucky to have her in this video.
Great tips! That pen on paper sound in your video gives me the shivers every time in every video where you do it.
That`s very nice! I did not know the difference between soft and difuse light. Well done.
Love the video!! Thanks for making this!
Once again awesome info!!
Thanks for all the tips.
I use as many tips from you as I can remember during my senior photo sessions!
fantastic lesson thank you!!!
Hi Pye, Nice to see your again here! Great video! I really felt like another few steps were taken in the direction of getting comfortable with using strobes. Thank you Pye, Thank you Gabriel )))
Great info Pye! Very useful information, especially the explanation of the inverse square law😁👍 Thank you!!!
Another awesome idea. Thank you.
Wow, thanks for the easy simplification of terms
Great video, surprised I haven’t seen anyone else cover this. More videos like this please
Bring more like this ❤️
I love how wonderfully Pye explains how flash works, while model is thinking ... WFT dude I just want to be beautiful :D
Great video, appreciate the work that went into it. Keep it up 👍
Great video, learned a lot (I'm more of a natural light kind of guy but lately I've been interested in the special time freezing characteristics of flash photo)
Im a physicist in radiation protection and that inverse square law is definitely one of the easiest things to understand. I wonder which schools you guys visited…oh man
Happy New Year Mr. Pie!!! I would love to see a show on continuous LED Lights that are similar to an HMI source.
Extremely useful. thank you
Love these videos. Thanks
Thanks Pye - really helpful as I learn about flash
Outstanding explanation . Thank you
One of your best videos. Great model as well.
Learning about flash duration is extremely useful, Thank you!!
I needed this information before I buy a new flash. Thanks a lot!
Good clear information!
Really great info and really good instructor!!
Nice, actually learned some new information, it's been a while :)
Educative. Thanks!
Talking about misconceptions, there's a big one about math (the inverse square law: "... and we don't like math"). It's not that people don't like math. Actually people don't like teachers who can't teach math properly. And we usually blame it on math. I know for fact that math can be a lot of fun. And most people can get it with the right teacher. One more thing: having said that we don't like math, you start using math to explain your point. I like the irony of it.
Great video, Pye.
Ok this was actually super helpful
I plan to do more flash photography here in the Philippines so appreciate the lesson.
Me and the model: (Oh, is it finished? What's a flash?) Most useful explanation of the flash. Thanks Pie
"Business time" will always make me think about Flight of the Conchords.
Pye the Maestro ! I kicked the like bottom as soon the commercial let me do it
great tips abbout photography:)
Good review of some flash basics - thanks! I would possibly add in the discussion about inverse square law the important understanding that light fall off is greatest when the source is very close to the subject. This is super important to understand when you get into shaping with light. Further, since we know a light source is larger relative to the subject when it is closer to the subject, it is important to recognize this inverse square law property because it means getting closer to get softer light also means getting rapid fall off.
Maybe I'm jumping ahead here... I look forward to more of these short tutorial vids. Cheers!
Yeah I think you are a bit advanced for this tutorial but you are correct from the little I understand.
Thank You!
Nice job Pye!
Perfect!
Very nice and informative tutorial. As someone else mentioned, please do talk a bit more about flash distance and light fall off. Thank you.
Great explination on flash. So many say strobe, a mis-nomer... but I digress. Different light applications will change the theroy results, and no one mentions this. Space also plays a big roll based on bounce reflection. They explain the theory but not how it can be effected by different light applications and modifiers. many do not understand the theroy of the angel of incident light and incident vs reflected light. If they used film, they would be lost.
Great explanation
Very helpful
Awesome!
Fantastic.
Great thanks
Great seeing Pye here! Great explanations as well.
awesome!
very nice tutorial
interesting tuto. trying to improve my skills with d750+sb900+pocket wizard, quite limited for these equipments.
Nice! f-stoppers takeover when?
it is great and usefull inf thank u sir
love this vid
#1 - yes, indeed. And a perspective drawing of the flash beam would have explained the issue even better. Distance is a 1 dimensional thing but what we light with the flash beam is an area and the are, 2-dimensional, changes with the square of the distance change
One other misconception is power... for example, not all 400ws lights are the same, and some will output slightly more power than others. I think most people understand the concept of watt-seconds, and that say 400ws is 1 stop more powerful than 200ws (on paper at least) but that in practice, this number isn't exactly 1-stop. Sometimes a 400ws strobe can be 1.5 or 1.3 stops brighter and can depend on some things as simple as the backplate (the face of the strobe--not the modifier necessarily) which can reflect or absorb light (a black backplate will absorb light, whereas a white or silver backplate where the bulb plugs into, may reflect more light this giving you a little extra light in the process because of the reflective properties of the material -- many back plates / lfash heads where the bulb plugs into, are silver or white --- some are black though, particularly adapter brackets or extension heads.
Inverse-square law has a big deal with the contrast ratio (pretty crucial element in photography), not just with reducing the amount of light. And actually, it's quite easy to understand the inverse square law.
Thank you..
Wonderful
What is a good flash for a Canon 6d please? Great video good pace well presented
Just a small note..
It is not( 2^2)x like in the notebook but it is 1/(x^2)...
If you move x amount of feet (or Meters) away, you get 1/(x^2) the amount of light.
All the rest..... Great explanations and examples 👌👌👌👌👌
#1 The spread of the light has nothing to do with the law. It's only how fast the light falls off in relation to distance. Doesn't matter if it's an umbrella, snoot or fresnel.
Good point
The inverse square law is completely based on the spread. Light rays, waves or photons are emitted outward from regular light sources in a spherical pattern, traveling out from each point of emission (outwards in all directions). It is this spread of light (occupying a greater area with distance), that results in the falloff.
The light source within a flash emits light 360° in all planes at the point of emission (bulb or filament). Whether you use a snoot or grid does not change this - the modifier is merely restricting the beam after its emission state. It’s already in divergence from the source.
A laser has a different fall-off rate compared to regular light sources due to the vastly diminished divergence angle of rays.
A snoot does not result in a laser beam, it results in a constricted portion of light.
(If you were to examine the inside of a snoot or grid you would see that light from a flash falls on the inside walls. These light rays are being restricted and blocked, not reorientated. The rays that make it out are still diverging, and thus subject to the inverse square law.)
Pye is one of my favorite teacher and photographer. He is fantastic!
Needed this cause i still need to learn much more about flash photography
Same here. ;)
How about the relationship of how placing a flash placed further away from the foreground subject will reduce exposure yet at the same time the exposure falloff from foreground to background levels off but regrettably the relative size of the light decreases resulting in increasing hardness of the shadow transition. So now what; how big, how powerful and far do you place the light?
great video
thanks
Really entertaining
This is useful
Holy molly, how did she flip her hair almost completely the same way twice? :D Congrats!
Very illuminating Vid' on all three subject items (sorry about being punny) Thanks for posting
@ 00:27 Pi gives everyone the power to stand on water just to get the shot. 👍
Can you give a rough real number of the t1 values for the blurred/sharp shot? Or in other words: what t1 value should I aim for (real number, not "as fast as you can get")
Tnx
i have a new metz flash confused perhaps you can help...enjoy your videos.. in ETTL mode if i dial up flash compensation say +1 the flash tells me the distance the flash is good at but the distance it states actually goes down ...I would think it would go up??? more power more distance..? what am I missing? thank you Paul
And, the perceived light falloff from subject to background seems less if the camera is farther from the subject
You might want to reconsider this statement for all cases where the light source is not on, or at equal distance of, the camera to that background?
What does that mean?
Yes, and it’s seems he over simplified the Inverse square law to in unhelpful level.
Great video and I have no idea still (-:
To change the hardness vs softness of light on the subject, you can either A) decrease /increase size of the light source (relative to subject) or B) lengthen/shorten distance of light source to subject- either accomplishes the same thing. Is that correct?
Essentially yes, because what determines the hardness of the shadow is the angular size of the flash at the subject. So a 10cm head at 2m away will cast a very similar shadow to a 50cm head 10m(!) away. In terms of trigonometry, remember the tangent of the angle is the ratio of the opposite (half the flash-head size) to the adjacent (the flash distance). As long as this ratio stays the same, the apparent size of the flash, and therefore its shadow, remains the same.
Unusually, I didn't find this at all helpful. He didn't mention that even a big light source like a softbox will behave more like a point light source with harder shadows the further away it is. That's just as important as the inverse square law. There's no point in having a big softbox and putting it a long way away. Secondly, flash duration was not well explained. Better to think of it like a shutter speed. The shooter the duration, the less time for movement. As long as your flash is adjustable from say 1:1 to 1:128 you will easily be able to freeze action but you will need wider aperture or higher ISO to achieve good exposure.
And flash duration is not ‘fast or slow’, it’s ‘long or short’. I rarely see anyone explain WHY a larger light source and/or closer light source is ‘softer’. They might talk about the shadow edge/transfer, but they never talk about it looking at the light source angle of spread from the point of view of a single point on the subject. If you want to clear up misconceptions, get it right!
Flash duration has nothing to do with the cost of the flash unit. Flash duration is the time it takes for the energy to travel across the flash tube. So the smaller the amount of power the faster it will travel across the tube hence giving a shorter flash duration. Flash durations are shortest on smaller tubed flash guns/heads like Speedlites where the tubes are something like 2cm long. Studio lights with longer tubes typically give longer flash duration and are therefore not great at capturing high speed action. In short a small cheap flash gun can have a shorter flash duration than a more expensive studio flash.
People always make a lot of noise about the inverse square law, but let’s be honest, everyone checks their exposure in camera to make sure it is coming out right. It would be reckless to be so confident that you don’t check your exposure after you move the flash. Also, shooting in studio usually means multiple strobes, so moving one light totally throws off the balance of any fill lights. Inverse square is just not that useful.
Is the difference between soft light and diffused light that the first is with a large light and a modifier while diffused light is a small light with a modifier? If not, then please do it again as I do not get it.
Inverse Square does not work with all types of beams and lighting scenarios.
Using HSS to capture a series of movements in one image, typically used for ballet dancers?
You wouldn't use HSS to capture multiple flashes in a single image... HSS is used to achieve faster shutter speeds than 1/200" (usually), so it's only used to fast shutter applications. No need for HSS to trigger the strobe multiple times in a single long exposure (such as your ballet dancer example).
I'd love to see the model speaking up and explaining him the science behind the "inverse square law" properly.
#2 has been my point in photography land too. Then you get photographers who prove you wrong, not understanding the point. I have to say, it is very subtle. The challenge is to demonstrate the difference with pictures that clearly demonstrate the validity of the point as well as the relevance. My suggestion, shoot somebody with very visible skin pores to illustrate the difference and illuminate the disbelievers.
I didn't think it was possible to make the Inverse Square Law more confusing than it really is. This was satire, right?
Imagine being in math class and going "fuck that, i'm just gonna move to the city and become a model instead"
Then Pye shows up with his math lesson on a shoot.
For me, the inverse square law is just to make the use of light such as flash gubs, strobes etc.. super complicated but in reality.. it's just a common sense 😇
Thank you Adorama and Pye for trying to explain concepts people have a hard time understanding.
Unfortunately, most people get confused because other people who do not (completely) understand the concepts themselves are trying to explain them. Your explanation of the inverse square law could have been a lot better using a digram instead of numbers. And your example with diffused vs soft light is not really useful since the silver softbox without diffusion material is more or less simply acting as a bare bulb flash with some spill that softens the transitions of light -- it is not the same size of light as the soft box with diffusion material. Next time use a reflective silver umbrella with and without diffusion material and compare the resulting light patterns on the model.
The light lost It was depend on the f you used right? Since what i know is GN (iso number) = f number x distance.
The amount of light you loose is based on the inverse square law. Its based on light not ISO or f number.
