Absolute beginners guide to off camera flash

This is a VERY simple guide in order to allow someone who has never tried to take a picture using off camera flash to get a simple image. There may be alternative ways and I certainly have not explained everything. I simply wanted to explain how to take a simple picture using an off camera flash in a studio situation. The example ignores ISO and backgrounds completely and is only using a single light. If this tutorial/explanation goes down well I will move on to the next level but after that I will leave it for others as I am still a beginner myself. This explanation has mainly been written for Button Moon’s benefit after she bought my original lights.

Types of off camera flash

There are two main types of off camera flash which are strobist (camera flashes used off the camera) and studio flash (usually mains powered larger lights). Both types of light have their advantages and disadvantages but for now most of the information is the same.

Triggering the lights

You can trigger the lights in a number of ways using flash light, sync cable or radio transmitter/receiver. Usually most people now use radio triggers but there is nothing wrong with using PC sync cables. Most studio lights trigger in SLAVE mode so when one goes off they all go off. With this in mind you only actually have to connect your radio receivers/sync cable to one light.

My personal favourite radio triggers are the ones FITP sells which have a 3 pin port on them and can be connected to cameras, flashes or studio lights! OR the Lencarta ones but not the standard ones, the mains ones (they are the same price just ask for mains ones) SEE BELOW

Settings and setting up

In aperture mode, which is the mode used most often by enthusiasts, you select the aperture and the camera works out the correct shutter speed. This is based on the camera measuring the amount of light reaching the camera.

In shutter priority mode you select the shutter speed and the camera works out the correct aperture again based on the amount of light that the camera detects.

With off camera flash the camera does not actually know about the light coming from the flash system and so neither of the above modes will work.

If you try and shoot using off camera flash in aperture mode then your camera will try and expose your images based on the light it can see but will not know about the flash so it will be FAR too bright when the flash does goes off. For this reason we must shoot in MANUAL mode.

Switch your camera to MANUAL MODE or "M" but don't worry it is not as daunting as it sounds!!! HONESTLY !!

Right you probably now think that this is getting far too complicated and that you will give it a miss but it is actually quite simple. We all know that the two main settings are aperture and shutter speed. The camera still needs the right amount of light to hit the sensor and using aperture or shutter priority mode it gets the right amount of light by varying the OTHER setting. With studio flash the actual flash only lasts for a specific amount of time and so we have a FIXED shutter speed. This only then leaves us with ONE variable and this is the aperture (or we have to change the location by increasing or decreasing the light hitting our model).

So for THIS example we will use ONE light. Place your model in front of you (select a large teddy bear or similar as this could take some time :)). Now place the studio light just to your left pointing at the model and stand to the right of the studio light.

Select the shutter speed as 1/160 second

Select the exposure as f11 and take a picture.....

How is it?

If it is too bright close the aperture more ie increase the f number.... If it is too dim open the aperture more ie decrease the f number..... Do this a few times and you will find a setting that works for that light in that situation.

You could also have tried turning the lights up or down (or moving them nearer or further away) until the amount of light gets to the aperture that you set.

That is the absolute basics of studio photography!

You can get a light meter that tells you a good starting point but the reality is that you will get an idea of the settings to use VERY quickly and you can also use the camera’s histogram in order to find the right amount of light.

You can also try setting the shutter speed at 1/250th second to see if that still works. You may find that it does and can use that speed instead or you may find that part of the image is dark to one edge. If so drop back to 1/160th.

WHAT NEXT?

Setting up your camera - This was supposed to be the contents of my next tutorial but Garry Edwards (who is a member on here and who does Lencarta's training) has already written an article that covers it and has kindly allowed us to link to it. If anyone has any questions just stick them on here and they will get answered

I am going to write the next stage tomorrow, I was going to do it today but had to go back to the doctors with my back (its that camera bag!)....

GOING FURTHER STILL

Well this is where I am :)

Where to go next:

The TP lighting section.

Useful you tube videos : Posing

Garry Edwards does a whole host of training DVDs and PDFs (I'm buying them all!)
Lencarta's training days.


OTHER LINKS

FITP (Flash in the pan) - strobist kit, off camera flashes, flash cables, flash soft boxes, stands, radio transmitter/receivers etc

Lencarta - Studio lighting for in and out of the studio (this is the stuff I use in my studio). Worth PMing Garry Edwards re any questions on the Lencarta stuff as although he doesn't work for them he does their technical support and training days.

:lol:

this had helped me loads already :)
 
:lol:

Tracey if i had been drinking a drink, it would have been all over the keyboard by now

Hey darren, you should mention ISO :thumbs:

I did mention it earlier saying that I wasn't going to include it so as to keep it as simple as possible. The idea of this tutorial is JUST to get someone to the point of taking their first pictures with off camera flash.

I will do a follow up including lighting the background, ISO, flash sync settings etc and then leave it up to the lighting section to go to the next level :)
 
If I were to be taking a photo outside in bright sunlight and want the flash to fill in shadows on the model's face how would I go about it?
 
Thanks, I'll take a look, although I was hoping for something as idiot-proof as the guide you wrote above :D
 
Thanks for this Darren much apprectiated, from someone just getting in to portrature that is a nice guide and very useful. I know absolutely nothing about using a flash so am looking forward to experimenting, with the flash both on and off the camera. When off camera I understand that you will be setting the camera to underexpose, is this just trial and error (depending on flash power and distance from subject) or is there is there a set rule i.e. always about 1 stop underexposed.

You set the camera in manual mode based on what light WILL be available. So if you are using a very bright light nearby you might need to actually underexpose by 3-4 stops but forget the amount that you are underexposing because it is all about the flash. There is no "amount" as such.

You can get it about right using a light meter but I will go through that in the second instalment.

You will get an idea of where to start from quite quickly then you adjust and re-shoot after looking at the image/histogram.
 
Thanks Darren. Very useful info there and looking forward to the next installment:thumbs:

Cheers, Rob
 
Very nice of you to do this, but I have to ask ... do you sleep :p ?

Have you been coming over to Saudi and seeing what I'm doing :suspect:? I use a large sized Whinny Pooh, works wonders :thumbs: up to a limit.

Can't wait to get to the next instalments in this tutorial, adding 2nd light and how to meter with two lights; adding a 3rd light (for model's hair) and how to meter for that?

Thank you for taking the time to do this.
 
Nice write up Darren... Is this replacing your 365 days of Mac stuff :D... I'm looking forward to the next two or three... but I need to get some more guns... and triggers.

Bears can be useful!

I have been sat waiting for my daughter in the car thinking about part 2 & 3 :)

It will only get as far as you say because I am still a beginner in the studio. I wrote this mainly for Tracey but realised that if you haven't done studio photography before then there are lots of things that don't seem to make sense. Also manual mode sounds scary.

I am doing part 2 later if I get time and will take some pictures to add to part 1.

Will do a few examples with off camera flashes and studio kit but sold or swapped most of my off camera flash stuff now so might get someone else to take the odd image!

It might boost FITP's sales :)

There will only be three parts probably!
 
This is a very useful post and should help people to get started.

Fact is, a lot of people seem to think that flash lighting is complicated when it's actually very simple, especially when using studio flash.

The first step is to understand the process, which is explained in this thread
And the second step is to practice and experiment

This article, on how to set up the camera for studio flash, may help too. The principles also apply to hotshoe flashes used off camera

The very man I have come to when I get stuck :)

Seriously that article removes all need for me to explain it all again. I will add the link to the first post.
 
Well done Darren - a good starter for those of us interested but not knowing where to start. I do have some remote triggers so should have a play.

It really is addictive and not expensive either. As you have the remotes and a flash and I would suggest probably a tripod you can just stick the flash onto the tripod and away you go. With the addition of a flash softbox like FITP sells you have a great starter kit.
 
Superb, intersting, clear article Darren. How I did not spot this yesterday or today I don't know, but glad I have.. nice one!

I only wrote it after 10pm yesterday so that might explain it ;) Thanks for your comments.
 
:thinking: How about "an absolute beginners guide to using a flash on a camera but not the actual on-board/built in flash but using something like a SB600/SB800/SB900" :shrug: :p :coat:
 
:thinking: How about "an absolute beginners guide to using a flash on a camera but not the actual on-board/built in flash but using something like a SB600/SB800/SB900" :shrug: :p :coat:

So how to use a standard flash, bouncing it, daylight fill etc.........

Sounds like a good idea but not for me to do. I use mine in TTL with adjustments to EV plus CLS thats it so maybe someone else can volunteer for that one!

EDIT: I think John "Kaouthia" might be able to do that one he does seem to know what he is doing with an SB :)

EDIT2: I've sent him a Pm and asked him.

I think as far as the light principles goes, Mr Edwards up there is probably the better man than I to do this. :)

The main difference with speedlights is just the lack of a modeling light and lower power output than studio strobes. Other than that, the basic principles don't really change between the two (aside from manufacturer or model specific features that may or may not apply to one or more manufacturers such as FP High Speed Sync, repeat/stroboscopic flash, CLS/AWL, etc; and even those can vary from flash model to flash model and between manufacturers).
 
Thanks very much for the clear concise explanation. I love it when someone explains in words of one syllable a concept that I have difficulty getting my head around!
 
When you get really good you can have a studio like this one:

This really is worth a watch :)

Thanks for this Darren, a very interesting read and timed well.

I just used AV, ETTL and 2 speedlights off camera for some social club portraits and they were so bad it was embarrassing.
Getting the basics right should mean not spending hours in post trying the rescue them next time. …look forward to the next instalment.
 
I have decided that I am going to do a 52 to follow my 365.....

I am going to do an "Absolute beginners guide to XXXXX" every week for a year and post them on here with the resources hosted on a new site. Just need to either wait till the end of the month or find a commercial sponsor. Should be a good deal for them for the massive price of about £15 per year :)

I will tidy this page up with some pictures tomorrow and have done the images for "An absolute beginners guide to shooting a table top studio using Nikon SBs". One or two of the 52s will be re-hashing or a whole group of the 365s into one article updated for the latest version so "iWeb 2011 create a web site", "iDVD 2011 create a customer slideshow with low/high res images" etc but most of it should be new.....

Anyway if anyone has any ideas for one of my 52 then please PM me.

Good starting point Darren. Only thing is this:

You can also try setting the shutter speed at 1/250th second to see if that still works. You may find that it does and can use that speed instead or you may find that part of the image is dark to one edge. If so drop back to 1/160th.

Set your shutter speed at 1/160th and leave it! Shutter only affects ambient light, as flash time is always quicker than sync speed!

Other thing would be to put camera at iso 100. I would suggest f5.6 as a more realistic starting point, esp. of using flashguns rather than strobes.

Not trying to pick spots as really good piece, just a couple of things that may help out for some.

Thanks, I appreciate the feedback but just to clarify,

I was ignoring ISO :) Most modern Nikons for example are the same quality at ISO 200 as 100 hence 200 being the lowest standard ISO and there being a LO.1 etc speed which is the same quality just slower...

I was suggesting the faster speed so people can find what works for them, I tell them to try 1/160th first anyway and some people who have more ambient light will benefit from a quicker shutter. :thumbs:
