In a Flash of Moment


Today’s blog is going to be more for the mere photographic minded (and I hope the rest of you will forgive me for that). I don’t usually write about technique, because there is plenty of information about how to handle a camera out there – and I am more interested in the creative process of photography anyway. But this time I will make an exception, simply because the technique I am about to describe may boost creativity as well.

This post is going to be about how to make a shoe mounted flash not only work, but give an interesting and quite different look to your pictures. Flash pictures you may ask? That is always gonna be harsh contrast, lousy quality and no control on your part… But really, no! Before the digital era I used to be sharp and very good at using flash. I had to. Back then I was shooting slides, and to get the best quality I would usually use a slow film at 100 iso or even Kodachrome 64. When light went low, you had to be able to either use a flash or set up a whole shebang of lighting equipment. I got good with the handheld flash. At some point I almost as a rule used the flash – day or night. It became part of my signature. But when the digital era took over, suddenly I didn’t need the flash any more, I could just ramp up the iso-setting of the camera, and I was able to shoot in any lighting condition. How cool was that! I packed down the flash, and never look back again. Until recently that is. Not long ago I finally dug into my camera bag again, and found the old flash (and found out that I actually had to buy a new one, too), because it’s not bad at all, but really just another creative device in my toolbox – when I need that special look.

The main factor for success with the shoe mounted flash (or even better if you hold it in your hand with an extension cord) is to mix available light and light from the flash. And the trick to gain control of this mix is to think about the process as taking two pictures on the same frame – even though it happens at the same time – in one exposure. First you take a picture with the available light and then you take the same picture with the flash (or the other way around, if you like to think about it that way, because it really doesn’t matter, it’s only a mental exercise; as I said it happens simultaneous – at least for the argument here). And what happens when you add two pictures on top of each other? The two light sources will add up and make the final picture lighter – too light. Which means you will have to make each captured picture darker, so the total adds up to a correct exposure. Thus you will have to underexpose them.

Let’s see how that works in real life. And I will start with explaining two useful set-ups using manual exposure control. That will make it easier to understand the process, even if you are never going to shoot manually. Let’s say you are shooting indoor. You want to take advantage of the special look you can get from mixing equally available light and light from the flash. To get a correct added exposure you set the camera so that it underexposes the subject lit by available light with 1 exposure value (either stop down the aperture one step or cut the exposure time in half). And you set the flash 1 exposure value down, too. Where the flash hit the subject the total of the two underexposed pictures (which albeit is but one frame) will give you a correct exposure, while where only available light is picked up, the subject – usually the background – will be underexposed and that is fine. It doesn’t sound too difficult does it? Try it out!

Here is the other set-up I mentioned I would explain: It’s midday sunshine. The shadows under the nose and in the eye sockets of the person you want to photograph are black. Not to mention if the person wears a hat. Time to mount the flash again. But this time you will only underexpose the flash. You set it to minus 2 exposure values. The exposure for the available light is as if no flash was added. That’s it; you are good to go with a so-called fill-in flash. Two exposure values down on the flash doesn’t sound like a lot, but it actually brings the light from the flash so much down, that it will only affect the shadows. That’s why you with this set-up don’t need to underexpose the available light. Here is the beauty: You can mix any ration of available light and flash as long as the sum of the two exposure values you step down are -2. In the first step-up the available light was -1 and the flash -1. Hence the sum is -2. In the second setup the available light was 0 and the flash -2. Again the sum is -2. So if you want to give a little more flash than the equal set-up in the beginning, you could for instance go for -½ EV for the flash and -1½ EV for the the available light. The sum is still -2. It works!

I’ll stop now, and get back to the automatic approach next time. I have already written too way too much, despite the fact that in my previous post I complain about myself too often writing too long texts. So thank you for staying to the end.

    Hello Otto, this sounds very interesting, very interesting indeed, I am going to print this so that I can read, and studied it properly. Thank you very much for sharing this with us.

  3. granny1947 says:

    Oh Dear….far too much information for this old girl….

  4. photographybyjoylene says:

    Have always heard that using flash outdoors makes the pictures pop, but have never had anyone explain it this way with the -2 exposure! Can’t wait to try this with outdoor and indoor photos! Thanks for sharing this!

  5. I don’t have a hand held flash yet…but have been using my flash outdoors during the day and love it!

  6. A clear explanation, not surprising in your blog! Flash can be u useful in many cases andgive a specific look to a photograph. Thanks for this
    robert

  7. Ciao, hey, what great pics, thought you were a press/photojournalist toggie! Checked out your web page, yes you are! fantastic. Love what you say and feel about photography and being a photographer, totally agree. Ciao Lynne

    Dear Otto, I can never get bored to read your posts, long or short! It doesn’t matter for me. This is great writing and I will print too, how beautiful you are that you share with us. Thank you so much, the photograph was captured so beautifully. With my love, nia

  9. Terrific post Otto. I’m going to have to go out and test this. I don’t shot with flash much (probably because I’m not proficient at it) but I think its time to start. Terrific shot too.

  10. A.Barlow says:

    Nice read man. Used something similar to that technique in the past. Not to often though. Hey, so what’s going on in that photo?!?

    • munchow says:

      The photo is from a series of pictures I took of street kids in Kiev, Ukraine. This was during wintertime and the kids try to stay warm by the fire or underground by some heated pipes. In the picture they a sniffing glue and getting quite wasted. A sad story…

  11. nomadcitizen says:

    Hi Otto,

    Thanks for the post, very beneficial for me ! Please keep posting if you have more tips !

  12. seabluelee says:

    Write as long a post as you want! This was a clear explanation and useful information. I appreciate it.

  13. eof737 says:

    It’s a great shot and the fire glows brightly… Technique makes my eyes glaze over. 😆

  14. hellenjc says:

    Brilliant and utterly depressing photo Otto…

  15. magsx2 says:

    Hi,
    Very handy information, thank you for the tips. 🙂

  16. souldipper says:

    Thanks, Otto…I keep promising myself I will get through my dyslexic phobias about settings! I love photography so much, but find even using my cheat cards hard. I cannot do the settings fast enough when I need them!

    Never mind, though…my dyslexia would frustrate you into tears. I am thrilled when I manage a really decent shot on occasion – sometimes by total fluke!

  17. danitacahill says:

    Thanks Otto, always glad to read about technique, too.

  18. Sunshine says:

    Well, truth be told . . . you lost me at the start of the second paragraph. Sorry. 😦 Oh, my! What on earth were those two doing?? Maybe that’s the expression I gave you at the second paragraph. Oops! 🙂

    • munchow says:

      I thought being a technical this time would mean losing some. But I hope you can forgive me? As to what they are doing, look above. They are to boys which fortune hasn’t look down upon.

  19. I’ve saved your lesson on a sticky that will now live on my desktop for reference. Thank you!

  20. PC PHOTO says:

    Oh the good ole days of flash and fill flash. So glad you were disciplined enough to do the hard (digital) work. One day when I feel up to the challenge I may try out your suggestions!

  21. aFrankAngle says:

    Although my photography skills consist of point and shoot, my eyes can catch a good photo … and lighting seems to be a key element that gives it a magical quality.

  22. munchow says:

    You are quite right, my friend. Light is very important.

  23. Absolutely great post. I am personally not a big fan of using flash light but after reading your post I will have a go and try it. Thank you!!!! Well done!!!

  24. For a while now, I’ve been reluctant to use flash because it comes our harsh or even with red eye when done at night. I guess I was just doing it wrong. Also I’ve been using more my iPhone lately than my camera and I think the iphone can all stretch to a certain point than quality suffers afterwards. Thanks for sharing a priceless advice. So much insights that will be so useful to us. You are an inspiration to us that barely know what we’re doing when it comes to camera and taking stunning photos…Have a great day!

  25. likeitiz says:

    Keep the great photos coming!

  26. The Hook says:

    I feel more intelligent already….

  27. I thank you Otto for the lengthy post even if now I have to go back and read it once more to try and understand it ( you write very clearly), and I am a beginner so I need to read it step by step.

    Hoping you will be reunited soon 🙂

  28. Wonderful post Otto. Thanks for the information!

  29. dearrosie says:

    Oh god sniffing glue… sigh…

  30. Bindu John says:

    Great shot! And thanks for sharing all these useful information (though I am not an expert).
    One thing I agree is, before the digital era we were more careful, and produced better pictures. I started using a Yashica (my uncle’s gift to my mother in the 1970’s) with a very good lens – I realized it was a good one as our local photographer always used to admire that. All the adjustments had to be done manually, and as the film was expensive I spent a long time ensuring the settings before clicking. But in the digital era we can afford any number of errors. (Sorry if I deviated from the actual topic of the post.) 🙂

  33. Barbara says:

    Thank you so much for posting this! I try so hard not to use flash but there are times you just have to. You explained this very well!

  34. Fergiemoto says:

    Very interesting and good information. Glad you shared this technique!

  35. CherryPie says:

    That is a very dramatic photograph.

  36. Arindam says:

    Thanks a lot for this informative post. I do not have much knowledge on techniques of photography. I always use flash while clicking a picture, specially in nights. But while doing this, maximum times the final photo comes up with red eye.
    The photograph in this post, is beautiful & stunning. Thank you for sharing these priceless information here. You are an inspiration for all of us.

  37. t.on.air says:

    this is very useful. thanks!

  38. Klaudia J says:

    great work, velmi zaujimave a pozoruhodne portfolio s mnozstvom zaujimavych informacii, nadhernych fotografii, vyjadrujucich emocie a kazdodenny zivot okolo nas …

  39. Much appreciated info! (It was NOT too long or wordy; it was good solid advice for using flash to the best advantage.) Thanks for sharing your technique.

  40. That’s one of the best explanations of flash I’ve heard. Thanks!

  41. Kris Phan says:

    Ah hah! Finally, someone shows the youngsters how we worked the flash in the 70’s and 80’s. Simple, fast and nailed the shots every time. Fantastic article, sir. Not to mention your informative blog. Two thumbs up! =)

  42. BoJo Photo says:

    Great use of flash. I’ve got a new Lumodi beauty dish on the way for on location shoots. I love shooting manual.

    I love your photo!
