Using an on-camera flash often feels difficult to master, whether it’s with a built-in flash or one mounted in the hot shoe on top of the camera. The problem is simply the size of the light source itself (very small if we don’t use some devices to make it bigger such as reflectors or umbrellas) as well as the direction of the light, close to and following the axis of the lens.
Nevertheless there are easy ways to use an on-camera flash with amazing results. Paradoxically enough, it often means not using a flash when you think you should use it (for instance when it’s dark), but rather when you don’t need to but can add some stunning effect by using it. Such was the case I showed in the post Flash Away the Shadows a couple of months ago. And today I will show you another easy way to use the flash for a special effect.
This is a good way to increase both saturation and contrast for instance when shooting during an overcast day. In addition this method puts increased attention to the main subject. So when you need something like this, you might consider this way of using the on-camera flash for a special effect. In addition – and best of all – it’s very easy to do.
Simply mount the flash on the camera and turn it or or turn on the built-in flash if that’s what you have. On more advanced cameras, usually the ones without a built-in flash, I recommend turning the exposure mode to Aperture Priority, that is you choose an aperture suitable for your subject and the depth of field you would like to have, and the camera will automatically choose a correct shutter speed. You may also choose Shutter Priority, but then you will have to make sure the exposure will be within the range of what the aperture is capable of. As a general rule, don’t chose Program mode as this often – and normally – will set the camera to the synchronization speed for the shutter, and thus destroy what you try to accomplish with this effect.
On a point-and-shoot camera, you will usually set the camera for slow sync. That’s it. The rest you let the camera handle. If you can compensate the flash light, make sure flash adjustment is set to 0, that is neither over nor under exposed.
What happens is that the camera automatically adjusts for the added flash light so the main subject – or the subject that is lit up by the flash – will be exposed correctly. On the other hand, the rest of what is within the frame, further away and not lit up by the flash will be underexposed. The effect, as I mentioned earlier, is increased attention to the main subject as well as increased saturation and contrast.
If you want to understand what actually happens, think of it as two exposures happening at the same time. One exposure is by the flash while the other exposure is by available light or the natural light. Where both flash light and available light lit the subject there will be too much light, since one is added to the other. Thus the camera compensates for this overexposure. It does so by choosing a faster shutter speed (if you have put the exposure mode on Aperture Priority). Changing the shutter speed doesn’t affect the flash, but a faster shutter speed will make the available light darker. So where the flash doesn’t light the subject, the result is a darker exposure.
This much said, you don’t need to understand the underlying and technical function of the camera to make use of the effect. But remember this is for daylight use, not when it’s dark. I used effect for the photo accompanying this post. It’s a photo shot during the celebration of Puerto Rican Day in New York.
Excellent! This is a very good tip..
I hope you can make use of it. 🙂
Great advice–thanks.
You are welcome. 🙂
Good photo and informative essay, Otto. 🙂
Thank you, Frank.
You just never stop learning..there is so much that could be done!
Isn’t that what is so great in life, that we can keep learning!
Nice capture, Otto. And very good advice too 🙂
I hope it makes sense – and is worth trying out. 🙂
Thanks. Something I need to work on.
Flash is something we all need to work on.
Definitely a good lesson.
Good to hear (or read). Thanks, Allan.
i hate using on camera flash, so i will read your post later, that is how much i hate it haha i don’t want you to talk me into liking it!! 🙂
Flash on camera is good for you! Flash on camera is good for you! Flash on camera is good for you! Flash on camera is good for you! Flash on camera is good for you!
is that a subliminal suggestion? haha!
More like a subtle suggestion…
yeah very subtle lol so subtle that i didn’t pay any mind to it 🙂
I am disappointed. 😦
awwww don’t be, i HEARD YOU hahaha
I love the effect you got here, Otto. 🙂
Thank you, Sylvia.
I was away on a little trip for five days. I took my camera, and was looking forward to a good bit of practice — but it was cloudy and gloomy the whole time. It never occurred to me to use the flash outdoors. Now, I’ll figure out the settings, and try using my in-camera flash in the future. I did mess around in the middle of the night, and discovered that my camera could do this, handheld and without flash. I’m beginning to think this camera could do laundry and make coffee, if only I could find the right combination!
I wouldn’t mind have a camera that at least could make me some coffee when on the road… I hope you like this tips, when you give it a try, that is!
Great tips. I can use this right now in the rainy days. I am having a hard time because the light is so weird, and I’m trying to find the right combo. This will help.
I will certainly give it a try, then. Hope it works out nicely for you.
I tried this once with disastrous results…because I had no idea what I was doing. It was dark, so the shutter speed was slow and blurred motion ruined every shot. I’ll have to try your advice and try it again in daylight!
Yes, try in daylight, that makes a whole lot of difference. 🙂
Super flash shot to stop the movement and debouch the shadows ! Have a nice week
Thank you, Pat. Have a nice week yourself.
Very interesting explanation – I have tried it, but much too seldom. I have to rectify that.
It’s not for every occasion, but nice to have in one’s repertoire.
Nicely described, most people don;t think to use the flash when there is plenty of light. You can use other sources for fill light as well. In my post today, I used an LED flashlight for fill light on a leaf.
You are very right. And LED is a fun light source to play with. Thanks for the comment, Wayne.
Excellent read as always Otto. Packed full of good advice!
Thank you, Adrian.
Many thanx for the photo tips, Otto. There’s some really cool stuff in that photo, including the one guy’s adorned right hand fingers. I’ll bet it was a wonderful parade.
You are right, it was a fun parade to both watch and photograph. Thank you for your comment, Loujen.
Thank you for the information! This is a great picture. I love how you really know what your focal point is in every shot. It makes your photos interesting and focused.
Thank you for the lovely feedback. Sometimes I think I am just lucky…
Really great tips – thanks Otto. I’m always scared to use the flash. 🙂 Will have to experiment with it.
Just give it a try at least. Could be something you think would be fun. 🙂
I always hate the fear in the headlights look that people have when you take their photo using a flash!
Well, I guess you can either use that creatively or not use flash at all. 🙂
Thank you, Otto! Excellent tip. I’m looking forward to playing with this. I almost never use the flash.
It’s a good way to start exploring the use of flash. I will get back to more uses later in the week. 🙂
