in this week's episode I'll give you some tips for controlling on camera flash will change our background exposure independent of our foreground exposure adoramatv presents digital photography one on one where we answer your questions here's your host Mark Wallace hi everybody welcome to this week's episode of digital photography one on one I'm Mark Wallace well this week we have more questions about getting outside and shooting pictures on the go when you're traveling and specifically we got a question from Mike about on camera flash photography in Mike asked what camera settings and flash settings are used to overpower the Sun I'm not asking about fill-flash but rather how to properly expose for a subject or model while under exposing the ambient light does high-speed sink figure into this scenario well Mike we're actually talking about two different things and one is how to expose for the ambient light the second is how to expose correctly with our flash the cool thing is when we add a flash to our camera something magic happens and that is that we no longer have just one exposure to work with we actually have two separate exposures the first is the ambient light and that's the light we can't control like the Sun or street lamps or neon signs things that are in the environment that we cannot control and the second one is something we can control and that's the light from our flash and so when we're trying to overpower the Sun well the reality is that the flash doesn't actually overpower the Sun what happens is we're under exposing the ambient light in this case the Sun and then what we're doing is we're using our flash to properly expose our subject now for a better understanding of all of this stuff we need to get out and do it and so we're going to head down to the park and we're going to walk through all of these steps and show you the settings and everything that's involved but before we do that I need to point out one small thing and that is that all cameras have the ability to control ambient and flash separately when we're shooting in manual mode but Canon cameras have some abilities that other brands don't so what I'm going to do is I'm going to show you these steps that work on all cameras first and then when show you some tricks that are specific to canon cameras alright alright well let's get going alright well now we're here at the park and our model is Jade this is her first video with this and so she's going to be helping us out so I can explain how this works you so as I mentioned earlier we have two different exposures that we're working with one is the ambient light the light that we can't control like the Sun that's setting behind us right now and the light we can control which is our flash what I want to do is start with just the ambient light so we're going to do is I'm going to take the flash off the camera Jade's going to hold that for me just to illustrate what we're doing so the first thing I want to do is I'm going to take a photo and what I'm going to do is I'm going to expose for the background and so Jade is actually going to fall into darkness that's okay we're going to add a flash to bounce that out here in a second and then we're going to expose the background a little bit underexposed so we're going to let it fall into darkness so it's darker than it should be and that's just to illustrate the point that we can control that ambient light in a certain way so let me do that first and then we'll add the flash so Jade look right at me now again what I'm doing here is I am exposing for the ambient light so I'm looking right behind Jade actually so she's not even in the scene I'm doing this and I have my camera set at about 7.1 and a at a shutter speed of 800 so I take a picture of Jade we can see that the background is exposed okay but Jade is underexposed because what we don't have enough light on her well what I want to do though is I want to under expose the background now to do this I'm in shooting in manual mode what I want to do is increase the shutter speed I need to make sure I don't change my aperture value because the aperture value controls the quantity of light and we need to let the flash go through that aperture and have it as white as possible so I'm going to leave that at 7.1 and then what I'm going to do is I'm just going to increase my shutter speed until my meter and my camera says I'm underexposed and when I do that I'll take a shot and sure enough jade is almost completely in darkness and the background is underexposed now watch what happens let's apply that to having a flash on our camera so Jade if you'll hand me that now what we're going to do is I want to put the flash on the camera and this is a Nikon d90 I want to turn on my flash the flash is in AI TTL mode so it's just in auto mode and I have a focal plane on so FP is on I've set that on my camera so I can have shutter speeds faster than 200 of a second or maybe 250 for this camera so now what I'm going to do is I'm going to put my shutter speed back to where it was when I had a good exposure which was 8 hundredths of a second my aperture is still at 7.1 so the background is going to be exposed correctly and the flash will fill in on Jade and so we'll get a balanced exposure so Jade look right at me beautiful just like that sure enough when we look at this we get a great shot Jade looks great but what I want to do is I want to have that background drop and be a little bit darker so what I'm going to do is I'm going to increase my shutter speed so I'm going to take it up to oh about let's see about 1,600th of a second and when I do Jade remains at the same exposure so the flash is giving out the same amount of light and because the shutter doesn't have an impact on the flash only the aperture we didn't change that so Jade she stays exactly the same exposure but the background is darker we're controlling those independent of each other and so the key here is the aperture controls the flash output and the shutter controls the ambient light outputs are the exposure and so I'm going to increase and decrease the shutter just really quickly here to show you how the background gets brighter and darker really really quickly and Jade is going to stay exactly the same exposure so we're going to take a few shots really quickly here so this is 1600 shutter speed and then what I'm going to do is I'm going to take my shutter down to 640 I'm going to take it down even to 200 so the background is overexposed and I want to take it way up to 3200 and you can see really quickly in this series of photos the background is getting brighter and darker and Jade is staying the exact same exposure in all of those and that's how you can use this on any camera just set your camera in manual priority mode and shoot in manual and you can have your flash on automatic TTL eye TTL whatever your brand has and the flash is going to keep up with your cameras doing and since changing your shutter speeds up and down the background will fall darker or brighter it's a really cool thing that you can do and it works with any camera now there's one thing that you have to be aware of these on camera flashes only have so far that they can push light and so if you try to do this at a distance of maybe 10 or 15 feet it's not going to work because the flash is going to be bright enough to illuminate your subject so you have to be sort of right or what you can do is you can get maybe a PocketWizard system or an off-camera flash system and put your flash close to your subject and then the camera can get a bit farther away and your speed light is going to keep up well as I mentioned on set earlier the nikon is another brand of camera can do this but canon has a way of doing it it's a little bit different so I'm going to show you that now I have a Canon here this is a 7d and this would work doesn't matter what can a brand of canon camera make of camera Canon camera you have so I've got my 7d here what I'm going to do is I'm going to put this in aperture priority mode I don't have to shoot in manual mode and I'm going to put my aperture to 7.1 to match what we did with our Nikon earlier and what the camera is going to do is it is automatically going to expose for the background and fill in with a flash on our model so let's just do that really fast so Jade look right at me beautiful okay now we have this shot and it looks exactly as we expect it to look and what we can do now though is we can use the rear wheel right here to change the exposure compensation and by doing that the camera is automatically going to change the background exposure and so I'm going to do that really really quickly here so I've got my exposure set to correct then I have my exposure compensation – negative now – positive there we go just like that I'm just rolling this up and down so this is plus – even negative – and now when we look at these shots you can see that the background is doing exactly what we showed you before it is getting brighter and darker but Jay the exposure on her is staying exactly the same so on a Canon camera you can use exposure compensation to quickly change the background and it's really neat and there's one other thing you can do with the Canon camera that makes it unique and that is you can change the exposure on your subject in this exact same way using flash Excel your compensation so on the top of this camera I have a little flash plus or minus now watch what happens I'll set my exposure compensation to be at zero so I'll take my first shot here and it looks really good and then what I'm going to do is I'm going to put my flash exposure compensation on and I'll adjust the flash up or down so watch this so here's my first shot Jade looks good then I'm going to take my flash exposure compensation down by one now by two up by one and now up by two just like that you can see that the exposure on the background stays the same but the exposure on Jade is going up and down with my flash exposure compensation they're disconnected so you can cure the flash and the ambient light separately now in other brands of cameras when you use exposure compensation what happens is the flash exposure and the ambient light exposure both go up and down together they're not disconnected the only way to disconnect those is to shoot in manual mode and do it yourself well now you know the trick you can control ambient light as well as controlling the light from the flash just remember it's the shutter that controls the ambient light and is the aperture that controls the light from the flash and if you have a canon camera you can shoot in aperture priority mode and just use exposure compensation to make that background go up or down it's really really cool and so that's all you need to know to control those two exposures well thanks so much for joining us this week there's a lot of fun working with Jade and getting those photos I encourage you to try it out for yourself and if you get some good shots please post those to the Adorama Flickr group so we can all see those and as usual if you have a question about photography please send it to me at ask Mark at adorama.com and we just might use it on an upcoming episode well thanks for joining me and I'll see you again next

    Hello Mark, I just watched the video on flash use. I have the Canon 80d with the Godox TT685. The video was very informative, but you then mentioned the Canon camera is a little different. I finally got the flash to operate correctly. Now you mentioned to put the camera (Canon) in AV mode. In this mode, with the flash still operate in TTL mode with no issues. I have to go try this now. I have yet to find a good video on setting the flash. I understand that the flash has to recycle, or can u set for multiple flash. But i would only use the flash for close-ups or portrait use. Thanks in advance.

    Hi – I have a Son6A6300 and Godox V860II flash – In bright sunlight with Aperture set at 8 and ISO 100 – camera/flash set on sync and shutter speed set up to maximum 4000 I can't get a complete dark/black background – is that to be expected? – Am I expecting too much hoping for 100% dark/black background??? Please advise

    Question:
    1- if you compensate camera exposure to -/+, do you go opposete with the flash exposure or same direction?
    2- does flash exposure technically works on camera exposure or it is completely seperate?

    Canon 7D EV minus 2 image looks the best. Being a 7D and 7Dii owner the +/- EV and Fcomp I use a lot. Such an easy system to get results quickly.

    I have an NP-N1001 flash for Nikon and I am unable to go over 1/200 of a sec…also when shooting off camera if I don't keep it active for two min it shuts off. Do you know how I can start it back up when it's on a stand so I don't have to go thru the trouble to let down my stand to hit the on button to turn it back on?

    Before adding the speedlight to the camera you metered on the background. After adding the speedlight did you continue to meter on the background, or did you meter on Jade?

    This video literally just changed my life. Understanding how the shutter and the f-stop control the exposure for ambient light and flash respectively is invaluable. Thank you, Mr. Wallace!

    She was overexposed on the first set – check the highlights. Should have shown flash correction at that point and pulled it down half a stop. How could you possibly say the exposure on Jade was the same on the Canon series??? Mark, you're a better photographer than this. I know what you were trying to do, but you should delete this video – it's an embarrassment.

    I'd love to see this redone with nude modeling. The folds of the body and tones of the skin can get blown out or under exposed and I would love a tutorial for shooting nudes with flash.

    I watch this over and over….. in what mode do you use to get the exposure before you put the flash

    Am I the only one getting the point of this video ? All he's doing is showing us how to use a flash in sunlight to keep the subject even an not taking time out to figure out how to get an even exposure of the models face from just the sun alone. Not having one side of the models face darker than other. The rest can be fixed though editing very easily if need be .

    This was important for me because I didn't know that the Canon had independent control of exposure of the background and flash exposure compensation.

    You shouldn't point the flash directly towards the model…
