Common Misconceptions About Studio Flash Lighting

It's very important to understand the differences between flash and continuous studio lighting.
Why do photographers choose to use flash instead of using continuous light?
What are the disadvantages of using continuous light?
Where's the flash coming from and where is the continuous light?
Monoblock flash heads or power pack systems?
How is the power output of studio flash lamps measured and how do they compare?
Understand studio flash F-stops and power range.

[@vimalneha]

Karl is the best photographer and teacher. Many can take good photos, but one who can educate others is the true one. Joule part I learned from him in terms of F-Stop.

[@jlwilliams]

That should answer a lot of people's questions! One thing to know about pack-and-head systems is that they can draw a lot of power from the AC/mains... not a problem if you have a nice studio like Karl's with dedicated circuits for everything, but something to watch out for on locations. I used to shoot market-research photos in-house for a large corporation, and our little studio was next to the IT department... one day for some reason we had to fire both 2400-joule packs at full power, tripped the circuit breaker, and all the computers next door went dark! They were not happy with us...

[@VisualEducationStudio]

Ha Ha yes good point!

[@filibertkraxner305]

Exactly why I'm considering if I can get by with a Move pack....

[@reality150tv]

well 2 packs on uk system would be 20 amps if was 2400 joules x2 = 20 amps I think is correct. For usa it would be on 110v system, and 1 2400 joules pack = 2400 watts would be 20 amps , with most circuit breakers 15 to 20 amps. But that isnt telling everything I assume the 2400 joules is only the output and not power draw.

[@nateiverson8681]

@@reality150tv I think that's correct that the power rating is usually measured at the capacitors not the outlet, but I could see the charging circuits drawing too much power. I may be mistaken but I thought the UK had overcurrent control built into their power ports and often the plug itself. It's been over a decade since I personally lived there so I may not have it right. If I am correct I'd say this is less of a risk in the UK than the US where the overcurrrent control is only for protecting the in-wall wiring fom bursting into flames.

[@ChrisM-yq2pq]

Happened to me at hotel

[@hawg427]

When I was a Paramedic we used Lifepak cardiac defibulators to shock a persons back into a rhythm. The max we had were 360 Joules available. I cannot even imagine getting shocked by a 3200 Joules block. That will send you flying across the room. LOL Great video.

[@VisualEducationStudio]

I once took an Elinchrom 1200J monoblock apart to try and extract a loose screw. Stupidly I inserted a screwdriver in to reach it....Next thing with a big bang my arm was knocked back and the screw driver sent flying across the room. It had a 5mm burn mark into the metal shaft, luckily I was unharmed as I only had my hand on the plastic handle of the screwdriver. Lesson learned... Let a qualified technician deal with it.

[@_JeffMart]

For anyone that is confused, a Joule is the same as a Ws (watt second). 800 Joules is 800 Ws. I may have missed it but I don't think it was mentioned in the video, and I think in the US at least, studio light power specs are generally listed in Ws and not Joules.

[@VisualEducationStudio]

Thanks I thought about mentioning it but then I thought it might get too confusing! I didn't realise the USA used Watt Seconds on studio lighting :)

[@nilofido411]

Karl Taylor actually watts is equal to joule/seconds 😎 P(w)=E(j)/t(s) watts is power, joules is energy

[@peter_shadow7559]

Thanks

[@andyvan5692]

@@nilofido411 yes, watts is POWER ie: what is consumed by your toaster/heater, etc. so a 500W generator from a hardware store can power you shaver, a caravan small bar fridge, etc. Joule is a measure of heat energy, ie with food, a KJ of energy used while jogging ( but as a side note, defibrilators use joules as power settings to)- this is electricity, not light or chemical energy. I presume the use of watts is to estimate if this power pack can be used in the circuit of the building, ie if there is enough amps without 'blowing' the rcd or circuit breaker in the meter box, a bit like using a stick welder, you need a high current circuit to run these, so you don't inadvertently start a wiring fire, due to over stressing the wire in the house.

Thank you for this great video. I've been researching what to get for my first flash and since I've done a lot of commercial and industrial lighting design I was expecting to see terms like "lumens" and "photometry" and "beam angle" but nothing I looked at had those specs. I can see these studio flashes are rated differently than commercial lighting and I'm guessing I'll look for maybe imperial units in the states like Watts or something instead of Jules. My goal is to one day sell a minimum of one photo, but enjoy the creative process and learning with every photo. With your videos, I know I'll get there. Thanks again.

[@JochenVoigts]

Thank you so much for your super video! I am not a professional photographer but built myself a small photo studio with everything you need as a professional, only all of it smaller and terribly improvised. I want to upgrade my whole system, since the triggering of the small battery driven flashes has been unreliable, slow and too week. Godox is probably the brand I should go for but I’m quite uncertain, what the system should look like. I have been using up to 3 flashes and want a system, that can freeze action, e.g. my model jumping in the air. But I also shoot groups of people/families. I reserved about 3 to 4000 Euros for that, now all I need, is a sensible combination of flashes, everything else is already available. What would you suggest? How much power do I need? My studio is 4X5 meters. I don’t earn money with my photographic work and don’t need to. It’s all just a lot of fun!

I love it, thank you. Why you switch to Broncolor from Elinchrom set? What is your consideration?

[@VisualEducationStudio]

Hi, I wanted a better choice of lighting modifiers (such as the Para's) and faster flash duration for high speed work

[@steveveld9244]

Another great advantage is that u don't need a flash trigger, which is visually brand specific.

[@00Skyfox]

That remote flash trigger on the camera appeared to only have a single contact on the bottom of it, similar to much older speedlites from the film days. Does that still have any sort of camera-controlled TTL flash metering or is it exclusively manually controlled settings?

[@VisualEducationStudio]

I can't see any point in TTL on a studio flash, the whole process of working with light in a studio is where the photographer makes the decisions on the exposure level of the flash. The trigger fires the flashes and you can also control the power up and down from the trigger if you wish but I prefer to walk over to the light and change it on the dial or do it from the app or computer controler.

Is there a way to use a Generator Inverter for 2 Bowens Gemini strobe Lights 500w? Is it safe? Of course the generator could work for many more things but was thinking if it's a considerable option for location shooting? In case of taking them or just stick with the speedlites?

[@VisualEducationStudio]

Ha Ha good one.

[@akpevbe]

Big fan of your work Karl, but at 6:09 i doubt that one of the reasons people get the power pack systems is bcus of the controls for the flash being on ground level. Every good flash system now can be controled from the trigger which is mounted on the camera regardless of the hight of the flash light.

[@VisualEducationStudio]

Thank you Akpe, yes I did mention that some monoblocs can be controlled from wifi apps and the triggers however I personally often find this fiddly (lost wifi, not knowing which light etc) and prefer the convenience of having the controls to 3 lights on one pack at ground level. Of course the desktop apps and mobile apps have gotten much better and it is probably as convenient but there is still something I like about having it at your fingertips. The outright main reason for most pros opting for packs would be the other features I mentioned and the extra power.

[@akpevbe]

@@VisualEducationStudio Totally understand dude 👍🏿

[@emanuelschimpfossl5919]

Is the rule for the joules to light ration the same with Watts? Like, is a 400watt flash one half a stop worse then a 600watt?

[@VisualEducationStudio]

1J = 1ws. So yes your calculation is correct.

[@Maxime-ho9iv]

Although I understand flash has the ability to freeze movement compared to led, is there any actual application for led in photography? Also, what do we get with broncolor or prophoto lights compared to let’s say much cheaper alternatives like godox? In the monitor world, yes you can get a very good benq but eizo will still give you much better uniformity.

[@VisualEducationStudio]

Hi Maxime, some people just understand continuous light more easily, in a sort of 'what you see is what you get' manner but as explained it's not as versatile for many reasons, especially when photographing people/fashion. In relation to your other question on lighting brands, light is light out of a flash tube but it's how long it lasts, how consistent the exposures are, for example every shot with my bron light is going to be exactly the same exposure which means layering images is easy. Durability of the brand is important to pros as the equipment gets a beating. And most importantly for me is what are the choice of modifiers available to me.

Hi Karl, could you perhaps direct me to an overview of (T.1) flash durations for specific power settings? I am running into the limits of my 800L's with dance photography and would like to compare with several power packs (move and scoro) to see which one would suit me best. I haven't been able to find the information so far.

[@VisualEducationStudio]

Hi Filbert, I'm surprised you're running to the limits on your 800L you'd have to compare the duration specs to the 800S on brons website then against the Scoro. The Scoro gives you a bit fast duration and a bit more power but as with all of their fast flash durations you have to drop the power of the units down to 5.5 or below to get the really fast speeds.

[@filibertkraxner305]

@@VisualEducationStudio I was shooting a group of dancers with a narrow grid + gel, which ate quite a few stops so I needed full power on the 800L. I'll try to find the Scoro specs again. Maybe a flooter on the 800L would do the trick as well. Thanks for your reply!

[@filibertkraxner305]

@@VisualEducationStudio I did some more research. Turns out I should have used the HS mode at power setting 9 (not 10), then bumped the iso one stop.

I'll still check out what extra the packs deliver though, as a bit of extra depth of field is always welcome.

[@Adrian-wd4rn]

Would you say continuous light has an advantage over flash for film photography? Or should I use my modeling lamp to find out the right placement of the flash head before taking the shot? Or is this kind of a vice versa scenario?

[@VisualEducationStudio]

Hi Adrian no I don't think continuous light has any advantages over studio flash lighting for stills photography whether it is digital or film. At some point in the future when it's possible to achieve clean images at 64,000 iso and assuming you can work in a completely darkened studio that has no ambient light leaks as well as the continuous light being adjustable in 1/10th of an f-stop with a CRI of 100, then it may start to have some advantages.

[@VisualEducationStudio]

Hi, it sounds like you've already made up your mind and you are going to need to sell your current stuff. If I was buying 35mm again then I'd probably go Sony and their 90mm Macro lens which is excellent. If I wanted to go Medium Format on a budget then I'd X1Dii (others will argue Fuji, but I need higher sync speeds for my fashion work). I think the new Canon Mirrorless also look interesting, I've got older 5dmk3s still working fine but I use the H6 for 99% of my work.

[@Kukainis]

What's this Joule thing ? You're the first photographer I've heard to use Joules instead of Wats.

[@IAmSamuelCharpentier]

Actualy, 800J/256 ( 2 to the power of 8 is 256 ) gives you about 3.125J of light on the Siros 800, wich is smaller than the 3.3J of the Unilite

[@IAmSamuelCharpentier]

What I try to say is that power 0.5 on the Unilite and power 2 on the Siros 800 is the same, it's only upward that the difference exists, that's kind of missleading because while Unilite 3200 power 10 means 2 stops brighter Siros 800 power 10 but their lowest point are the same, but described as 2 different power values...

[@IAmSamuelCharpentier]

And then they say studio strobe don't have to be complicated 🤷🏻‍♂️

[@VisualEducationStudio]

Yes that's the maths but I find at the very lowest powers the joules can be a bit iffy in their supposed values and actual output. The Scoro shows you the Joules which is nice. It's obviously got 2 stops up above the Siros if only using one lamp in the pack (which is not very often).

[@user-tv1yw3cb6f]

is that 3000 j flashlight brighter than the sun ?? and how much lux it emits ?

[@VisualEducationStudio]

It's all relative to how far away you are from the light and how long you look at it but if you fired 3000j at your eye (don't do this) from a meter or two away you won't be able to see much for quite a while, and that is just for about 1/1000th of a second. If you looked at the sun for 1/1000th of a second it wouldn't hurt as much. However you generally use studio lights with modifiers on and not often on full power. I'd have to measure the output of the sun on a clear sunny day and the flash from a couple of meters to give you the lux but I'm not going to do that, you can probably find the answer on the web.

[@jay.mona.31]

5:20 Joules is not a unit of power, it is a unit of energy. The unit for power is the Watt.

[@VisualEducationStudio]

Yes one joule is equivalent to one Watt Second but in Europe studio lighting is described and sold in Joules (energy) so it's pretty clear to talk about it in this way.
