Flash Diffusers Don't Work (at least not how you think they do)! | Ask David Bergman

[@GastonShutters]

As a photographer I’ve never heard a better explanation to this matter like the one you just did Dave. Explaining the whys to beginners can be challenging and you’ve nailed it

[@ms3er396]

Agree 200% VERY well done explaination and the video overall including props and voice over is perfect.

[@naveen123454]

[@samuelsquires423]

Yep. I've seen 30m long videos explaining far less

[@jtinoco9859]

This is the best explanation I’ve seen/heard about flash modifiers, light softening and how these concepts really work. Thank you!

[@tomkolour3947]

A typical actions speak louder than words tutorial, the best explanation I've watched on diffusers, I'm doing a " Park LIght's " switch on this evening outdoors, thankfully I came across this video and I've just taken the diffuser out of my bag. Thank you 😀👍

[@GertJanKole]

I'm using these 'diffusers' for a different purpose: if you bounce your flash straight up, you lose the specular highlight in your models eyes. Snapping on one of these caps while directing your flash to the ceiling, will create a small strip of light, which reflects in the eyes and brings back some life.

[@KandiKlover]

Any proper flash will have a little white pull up tab that does exactly that. Otherwise it's easy to make with a little bit of card stock or cheap to buy if you can't be bothered.

[@ThomasRuhlandPhotography]

David, you ré the only one on earth answering and explaining correctly. (except that the sun is not the biggest light on the galaxy, but on of the smallest. The biggest in our solar system, just in case you have astronomers following your channel ) thanks for your precious advice

[@simonbrown6903]

Great video and very informative! I had the small plastic one and I pretty much found that it was useless, so now I have a magmod style bigger on camera flash diffuser that works much better. But I didn't realise the difference in how they can work indoors vs outdoors. Always learn something new, thank you David 😊

This is the most useful, clear, and concise video on flash diffusers and light that I have ever seen. The principles of light that David discusses are important and relevant for any photographer. And, after watching this video, I realized that a good light like the Profoto A1 would not meet my studio photography needs. Size is important. Thank you, thank you.

[@szinski]

I would have liked to see the difference between the diffuser aimed at the ceiling vs. standard bounce flash (and possibly another with the flash's white reflector card pulled out). But, great video!

[@jazzpote4316]

Yeah it's a pretty meaningless experiment

[@nikhilreddyguda9411]

Exactly, I was like "that's not a fair comparison". I have got the answer for direct flash with and without the diffuser but not sure bounced flash with and without diffuser.

[@DavidHager1]

Ugh it took me a bit of Googling to find this answer because it has been bothering me for a while! I just did the same test in the darkness as you with an octobox to prove the diffuser does not equal softer light, but I kept searching for a clearer explanation because I found it very odd nobody has talked about this. I think a lot photography teachers mislead people by saying modifiers make things softer, it’s fine colloquially but in all my tutorial watching paid and free I’ve never seen anyone make this distinction and I’m sure some of them don’t really understand it or haven’t thought of it much themselves. Which is bad, because it’s only by truly understanding the fundamentals that we can properly push things further. Good video, and always there’s a feeling a relief when you find a video on just what you were asking for and you don’t feel like you’re the only one with this question.

[@rocknationac7332]

Two years ago, I grudgingly put up what I thought was a little too much money for a plastic pop-up flash diffuser. But it paid for itself that very weekend: a grand total of zero complaints from the eight rock bands I photographed about my flash getting into their eyes, and an additional zero complaints to this day!

[@JohnCornicello]

Good description! I think that softness should be discussed distinct from contrast. I define soft vs hard by the shadow transition. As you note around <a href="#" class="seekto" data-time="500">8:20</a> putting on the diffuser doesn't change the size of the light, so the transition remains the same hardness. What diffusion does is spread the light. This allows the light to bounce off of objects in the environment (environmental fill) which fills in the shadows, which lowers the contrast. We still have hard light, but with more open shadows (assuming a light color environment--in a large dark room or outdoors there is nothing to bounce off, so neither the transition or the contrast change, you just waste power). Diffusion does not soften light unless the diffuser is much larger than the light origin. As you noted, put the light in an umbrella or a softbox, or put a scrim between the light and the subject and you soften the transition. The contrast is still dependent on the environment. Now about those people who put on a diffuser and point the flash upwards while working outdoors...

[@PeterSodhi]

This is a freaking incredible masterclass.

[@thegirlwholeftthefridgeopen]

wow that was easy to understand! Thank you, David, I also thought that that was what a flash diffuser's purpose was !!

[@Nahan_Boker94]

finally, Thats why its much better with umbrella lol. I once had these plastic diffusers and it looks the same as you said and show. Using more power also. Then I bought the umbrella plus with the white fabric and its was totally different.

[@lawcecil8246]

Finally I know that small plastic is how to use, thank you very much.

[@jerrye1001]

Thanks David. I had the same question and you answered it perfectly.

[@photo2000]

very good explanation of these diffusers! what these diffusers can do is make the speedlight behave more like a barebuld flash, where the light emits in all directions. It is good to use if you are taking photos at close distance to people, or close to groups of people and need to spread the light really wide. Sure the speedlights have zoom functions and even a wide angle diffusion panel, but the plastic diffuser will make the most omni-directional light. The other most important point made about bounce flash, is bounced light will take on the color of the surface you are bouncing off. So, if you are bouncing light off a ceiling that is made out of unpainted wood, the light that then falls upon your subject is going to be quite warm in color. If you are mixing this bounced light with the direct light that is coming from your flash, you will have mixed colors, as your flash color temperature is alot cooler. Even a ceiling or wall that appears near white, say a cream color, can actually change the effective color temperature of the light coming from it. The key, be carefull when bouncing light, and know what it is doing to the color of your light.

[@duckhanhpham4753]

Thank you so much for explaining flash diffuser only working limited indoor by bouncing light around but not working in big hall and completely not working for straight from flash diffuser to subject that is the same hard light without diffuser.

[@DavidBergmanPhoto]

Thanks! Send it into www.AskDavidBergman.com please.

[@Gainsborough89]

Use the stoffen diffuser to “convert” your speedlite to a “bare-bulb” flash/strobe. Just like you wouldn’t use a bare-bulb strobe on its own, neither should you use your speedlite with stoffen diffuser on its own. Use it with a larger light modifier, like a shoot-through/bounce umbrella, octabox, etc. And voila, you have a bare-bulb “strobe” with the budget of a speedlite. Of course, actual strobes would have much higher power available, but hey, when you’re on a tight budget, this works brilliantly.

[@tonysvensson8314]

The biggest lightsource in our solar system!!!

[@TheJadedFilmMaker]

hmm... helpful for face shots yes sure. but I've got the latest fancy expensive on camera sony flash and when doing full body, that diffuser that comes with it is REALLY helpful for spreading the light so that it's not just lighting up half the body. so in a way this video is a bit misleading in that sense. as in, direct front on, yes definitely I will be using the little diffuser.

[@cronas2]

I was always taught that to use the Stofen, the flash head should be at something like a 45° angle, and not pointed directly at the subject...

[@jimwlouavl]

Very helpful video to see exactly what the diffuser does and doesn’t do.

[@theunyet.curatedlife]

thanks for the video, David! So you don't use the diffusors when shooting on concerts? What technique would you recomend for shooting at the party in the evening outdors?

[@DavidBergmanPhoto]

I don’t use flash for concerts. As for outdoors at night, it’s tricky and depends on the look you want. If there’s something you can bounce off of to soften the light, then great. Otherwise, you’re going to have hard light.

[@hannahsaywell811]

wow! I am beyond impressed with this video

[@WhenWillILearn]

I always thought it was for reducing the specularity of the source

[@erikswenson2659]

One thing a diffuser can help with outdoors is getting full flash coverage for an extreme wide angle lens. If you use a straight flash designed for 18mm or greater lenses with a 10 mm lens, the flash will tend to spotlight the center of the photo and fall away at the edges. A diffuser can help scatter the direction of the light and produce a better shot.

[@DavidBergmanPhoto]

Many flashes have a little drop down diffuser for that purpose. I think it works better because it only spreads the light just enough to cover the wide angle. The diffuser in the video let’s too much light escape out to the sides.

[@LimaGolf284th]

Thank you David.

[@JBSwanstrom]

Thanks David! Reminds me of the olden day gaffers tape and an index card.

[@kenn6592]

[@nfmosphotos4624]

Thank you for this video! Such a simple and straight forward explanation with examples!

[@keithw8646]

Maybe a follow-up demo of bouncing flash light off the ceiling with and without the diffuser? Does it make any difference then?

[@jpdj2715]

All true, David. Some speedlights/speedlites have this pull white out tab reflector. If you go to the end of the video, the bounce flash is introduced. This can make the light very soft as the size of the light source is defined by the flash angle and its consequent lit spot on the ceiling, and a wider flash angle gives a very large source. But the reflected light comes from above and gives dark shadows under the chin, or over the eyes and under the nose. Pulling out the speedlight's white tab will reflect part of the flash light horizontally directly forward and fill these shadows. (Based on assumptions about angles being middle of the road.) Sometimes it is more interesting to direct the speedlight at a white side wall instead of at the ceiling and mimic a window shot - and here the white tab can fill too. As you explained, David, the dome steels light from you, recycling time and pops reserve in your battery. In these bounce scenarios it also throws some light to where it contributes nothing. I have a couple tiny speedlights that have no pull out tab and with these I occasionally use dome in bounce flash. A rubber band with a white (or aluminum?) plastic card would be better, for me.

[@DavidBergmanPhoto]

Yup. I sometimes use my hand to push light forward too.

[@vazquezfoto]

Many thanks David, from Spain, sorry for my poor English. I absolutely agree with your words. I was very surprised when I saw profoto's promotion videos of their the round speedlite using the sphere dome in the street. They said several times it was for diffusing the light. They were in a very open space in the middle of the street. To me, using the dome in that situation is simply wasting energy. They are supposed to be experts on lighting, so I am still wondering why they present the dome as a diffuser in open spaces. Your thoughts please? Many thanks!!!

[@DavidBergmanPhoto]

Marketing? Profoto makes some fantastic gear and it is true that it diffuses the light. That doesn't mean the diffused light helps you in any way. :)

[@kurtlindner]

For _some_ reason lighting companies, Profoto is a frequent offender, often produce absolutely awful product videos when the item is shown in use. It boggles the mind.

[@jasonbodden8816]

@Jose Vazquez Just remember that diffusion and softness are not the same. Your light can be diffuse but not necessarily soft. Diffusion more speaks to the level of specularity and managing highlights/hotspots).

[@huwmorgan51]

Should you use a diffuser in conjunction with an umbrella to spread the light out before it gets reflected back?

[@DavidBergmanPhoto]

Yea that’s a good use scenario.

[@eradicator187]

I learned something new today. Thank you

[@phatcrayonz]

Thanks David you are the Man!

[@ropeyarn]

Well said. The stock diffusion dome does make a bigger difference at closer lighting distances of 2-5 feet where the bounce reflections and apparent light source size work in your favor. Think pet, still life, and head shot, photography. As an event photographer I wrestle with the exact situation in your video, and the ceiling is always too high for a bounce.

[@Jambo1999]

Good point about being an event photog. I can't use a large diff user.

[@tricknee253]

Big help. Thanks David.

[@irfanmoosani7771]

Wouldn't the flash light bouncing from ceiling will get diffused the same way with or without small plastic diffuser?

[@kurtlindner]

A simpler way to think about what the diffuser is doing might be like this -The speedlight can probably zoom, let's say 28mm-105mm, so we can say the field of view covered by the cone of light emitted is 75°-23°, the diffuser widens the field of view covered to 180°.

[@stevem.6557]

The Stofen cup is taller than the one used in this video, so it kicks a little more light forward to fill in the eyes and under the neck, but like David said they are pretty much useless outdoors. They also kill that ugly blue-ish tint that direct flash can give, slightly warms the light.

[@DavidBergmanPhoto]

Yes. But there’s more light being pushed forward towards your subject. If you only bounce off the ceiling, you might get more dark shadows under the eyes and likely wouldn’t have a catch light. The diffuser fills in those shadows and gives at least a little catch light.

[@rickierecardophotography7406]

If you're bouncing the flash off the ceiling etc. How do you prevent the noise grain because the light source is not pointing @ the subject?. I experienced this issue this past weekend.

[@jimemery3772]

It's a useful explanation--well stated and produced. However, probably the most important factor to consider when faced with a need to soften shadows with any kind of light is the SIZE OF THE LIGHT SOURCE RELATIVE TO THE SUBJECT! Any explanation that doesn't specify this falls short of presenting a true understanding of lighting.

[@joem4866]

I too have used the Stofen Omni-Bounce in a bounce flash position with great results. However, it says right on the Omni Bounce "Don't use in bounce position" or words to that effect. I surmise that the little baffles and such will direct the light out of the bottom of the flask, yielding harder light. Agree or disagree?

[@DavidBergmanPhoto]

Not sure why they wouldn’t want you to bounce the Omni-Bounce. It’s literally in the name. 😳

[@dirgharajshrestha]

According to Canon, it's a bounce adapter and not a diffuser. Can be used outdoors to scatter and cover bigger area though.

[@NebulaChavez]

Thank you for this video - Have a GREAT DAY David

[@ErixAudio719]

So would it stand to reason that one should use the diffuser when using a small flash inside a modifier?

[@kurtlindner]

9/10 times, yes.

[@DavidBergmanPhoto]

Yes that can help spread the light into the entire diffuser and avoid a hotspot in the middle. Of course it depends on the size of the modifier but it certainly can’t hurt much since you don’t lose any light out of the back.

[@rekcedmedia3231]

Bounce is always best but those little dome covers are good breaking up direct light from a speed light and hitting folks a little ‘softer’ If your in dive bar shooting a band with black walls and ceiling skin tones look better those also.

[@gregorysargeant6305]

[@K3zz21]

Holy crap I didn’t even realize this. Thanks for explaining it do well!

[@longliveclassicmusic]

Very very very true…mostly. It's still a layer of diffusion. It wont make the light technically softer, but it will make it more diffused. It's like using a softbox without diffusion panels versus using it with them. The strobe will still fill the softbox and make it a large light source without inner and outer baffles, but it'll be more specular and directional than if you have them. In a speedlite's case, the entire fresnel head does not emit an even surface of light. The light is coming from a smaller area in the center and is blasted straight out. A diffuser cap will diffuse that and even soften it a tiny bit. I can totally see a more even spread of light in this video with versus without, though since it's such a small light source it's still less impactful than if it was larger.

[@DavidBergmanPhoto]

True that there might be a tiny difference if we were measuring it somehow. But practically speaking, it’s not something I would use to make soft light without bouncing it off a larger surface.

[@eduardolima5968]

Perfect explanation. Thank you very much.

[@TeddyCavachon]

I had a very interesting and educational experience back in 1972 of assisting Monte Zucker, the wedding photographer/ author / teacher who introduced the idea of using dual speedlights for shooting altar and reception photos. He had started in the era of shooting weddings in B&W with 4x5 Speed Graphic camera and a single flash (bulb) gun on camera. That worked for B&W because the dynamic range of the B&W film and print could record the full range of detail from the folds of the groom’s black suit to the separation of specular highlights and solid whites on the satin and beadwork on the bride’s dress. But when finally switching to color in the late 1960s and early 1970s photographers discovered like digital camera sensors today the color negatives and prints could not record the entire range with a single flash on camera. Biasing exposure for the white dress would cause a lack of detail in the shadows of the dark clothing. The solution was quite simple, used two light sources in a key over fill configuration as done with studio lighting. The challenge was finding a way to do it while moving around covering a wedding and controlling lighting ratio and exposure. Flat near-axis flash mounted on a camera hot shoe does not appear “natural” because we are accustomed to light sources - natural and artificial - coming from overhead which places the specular highlights from the source on the upper part of 3D objects and the shadows they cast below. Hot shoe flash shots look “fake” because the highlight and shadow clues the brain uses to discern 3D shape in 2D renderings are in the “wrong” places. Monte understood that and corrected the problem by mounting the flash on camera on a custom make bracket which put the center of the flash head about 18” above the taking lens of the 2-1/4” format Rolleiflex twin-lens reflex cameras (equipped with eye level pentaprisms) we used. Raising the flash directly over the lens put the specular and shadow clues in the “right” (i.e. “natural looking”) places on the face with the shadows falling down and mostly out of sight of the camera in single flash shots. The problem of recording the full range of detail in black and white objects was solved by adding a second identical flash on a rolling (modified medical IV stand) which was placed 45° to the side of the nose and above the eye line so the shadows it cast fell naturally downward. Part of the perception of light being “hard” or “soft” comes from the tone of the shadows. With the two flashes in an overlapping key-over-fill arrangement the lighting could be made softer looking by placing the off camera key light at the same distance as the flash over the camera. Placing the off camera key light so it was 2x or one f/stop brighter resulted in a 2x key+1x fill over 1x fill (<a href="#" class="seekto" data-time="181">3:1</a> reflected) ratio which was exactly the ratio needed to render everything in the foreground with detail from black to white (and everything in between) with “seen by eye” tonality and natural “mid-afternoon” 45° downward key light modeling, all without any modifiers on the flashes, instead using the key:fill lighting ratio to control the perception of “softness” via the tone of the shadows and carefully controlling the placement of the specular highlight and shadow clues on the faces via the direction of the light sources relative to the faces and camera. Exposure and ratios were controlled via the inverse-square law. Two identical flashes placed at 11ft on camera and 45° off to the side will produce a soft looking 1key + 1 fill : 1 fill (<a href="#" class="seekto" data-time="121">2:1</a>) “soft” reflected lighting ratio. Moving the off camera “key” flash to 8ft when shooting from 11ft makes the key light 2x brighter than fill creating the 2key+1 fill: 1 fill (<a href="#" class="seekto" data-time="181">3:1</a>) “normal” looking full range lighting ratio which is what we used most of the time. If moving into 8ft for a tighter crop the off camera flash was moved in to 5.6ft to keep it 2x or one f/stop brighter than the fill and the aperture was closed by 1-f/stop to adjust exposure. By systematically shooting from 16, 11, 8 or 5.6 feet with the off camera flash placed at 11, 8, 5.6 or 4 feet, respectively, it was possible to cover the entire wedding with lighting which gave evert photo in the wedding album the appearance of being shot in a studio or Hollywood sound stage - without any use of diffusers, just expert control of the lighting. I didn’t start experimenting with diffusers on my dual flash set-ups until 2001 when I switched to shooting digital. The only significant contribution they make is in the appearance of the specular highlights on damp or oily skin. What I found worked best were “scoop” style reflectors I constructed from 8-1/2” x 11” “fun foam” sheets with an internal stiffener with a top flap which could be opened on the fill flash on bracket over the camera to also bounce light off a low white ceiling for added “spill fill”. I shared my experiments and instructions how to make them on photo fora back in 2004-2012 time frame.

[@socratesvela8285]

What if, you ditch the diffuser and just pull up the white card and diffuse using a flat white ceiling? Is that better than just using the ceiling without a diffuser or white bounce card?

[@paulsophocleous2544]

The card is mostly just to give something to reflect in the eyes to form a catchlight, from my understanding. Bouncing the light off the ceiling is what will make the most difference in creating nice soft lighting in your example, not the card.

[@DavidBergmanPhoto]

“Better” is subjective. If your goal is to push more light forward towards your subject then yes, the white card will help achieve that.

Could you make a video like this again, but for macro instead of portrait? Does the "cap" work there?

[@DavidBergmanPhoto]

Light still travels in a straight line, regardless of the distance to the subject. You can probably get away with a smaller light source but it just depends how big it is in relation to the subject.

[@uptownphotography]

Very well detailed video on this subject. Super well done David... Question Please: How are you getting zero ambient light at F/4 with 100 ISO and 200sec? I have a Canon 5D4 and although I have not tried this, I do shoot school portraits outdoors a lot it seems I would be still picking the background (on a cloudy day) and it would not be black. Granted I use a different lens (Canon 24-105 f.4 v2), but would love to know how you achieved a black background. Very interesting. Thanks and again super well done and interesting video. Philip NYC Area

[@stanspb763]

The ambient light outdoors is still rather bright compared to the room he was shooting in.. If you are using a plain background you do not gain benefit from the mid-depth of field at f/4 so just stop down and get better resolving power from 5.6 or 8.0 and will be cutting ambient light. If outdoors and there are background distractions get closer to the subject and use a FL of 50-80 so the distance ratio between camera to subject to the background to get more blur of the background,. If you are shooting a lot of people, one at a time, use a backdrop so you have more consistent control of ambient compared to letting nature control that light level that constantly changes with cloud density and time of day.

Hi David great to catch your video on this topic! I like to use these mini diffusers on a speedlite with an umbrella or softbox to help spread the light about for potentially more even light within the box or brolly more than the square recessed speedlite does on own - also tried the small diffisers that flip down out of the flash which also work a little for this approach - what do you think of that have you noticed that little doodad helping at times? many thanks!

[@kurtlindner]

Yay, but it won't be doing as much as it does in combination with an umbrella. The softbox will already naturally scatter the light, and the inner baffle should help even out the source before it hits the front baffle as well. If the source can be pointed inwards, towards the rear of the softbox, that is even better usually.

[@MarkHickford]

Nay. Usually softboxes will have silver inner panels to scatter the light before hitting the diffuser panel.

Maybe if you're using a speedlight in a BIG modifier (like a 4ft octa). But you'll lose more light, so it's a trade-off between more even light vs. output.

Yea that can help a little bit to avoid a hotspot in the middle.

Great explanation, thank you.

[@shahrukken6578]

So if you're in a room with high ceilings and a lot of space, what can you use to get softer light? A softbox or flash bouncer?

I’ve seen some local photographers use two umbrellas in this case
