Metering for Light Ratios: Ep. 120: Exploring Photography with Mark Wallace: Adorama Photography TV

Adorama Photography TV Presents Exploring Photography with Mark Wallace. In this episode, Mark shows you 4 simple steps for metering light ratios. Understanding the light ratios of your lighting setup can make setting up a photo easy. It also makes it simple to recreate the same light over and over again.

Mark uses a Sekonic L-358 in this episode to determine the lighting ratio. The L-357 has a built-in function to do this, so you don’t have to do math in your head!

AdoramaTV features talented hosts including: Mark Wallace, Gavin Hoey, Joe McNally, Joe DiMaggio, Tamara Lackey, Bryan Peterson, Rich Harrington

  1. Agreed Eduardo, why they did not take photos is a mystery.
    Ok you have adjusted to a -1.3 ratio… Visual follow up is crucial, we have gotta see what that looks before and after.

    Plus, and this is a big stick up my bum, kill the open – anything longer than 2 seconds is way too long for YouTube.

  2. Someone told me that when you have the 2 light set up as you do in this video you go down 3 stops for your fill light.  Is that correct or how do you determine  what your fill is? Thanks

  3. They are Matthews Baby Jr. triple Riser Stands with Wheels, and they are available at Adorama. Look in the Description (right below the video) for a direct link.

  4. The triangle ISO-Shutter Speed – f Stop is obvious to anyone using a DSLR. But what is the way to use the other data shown on the lightmeter display : the EV ?
    How to read the numbers negative or positive ? Thank you for enlightening us !

  5. Mark, first of all, thanks for the great videos–I'm a fan. Quick questions: Are you just using those PocketWizards (I'm guessing they're Plus III models?) to trigger the lights with the Sekonic? Or are you also using it on your camera to trigger for shooting? If the latter, is there a reason you'd do that, versus the Profoto Air Remote transceiver?

  6. Two lights at 45º. The erroneus McAndless way of lighting aplied to photography. Simetric shades, simetric highlights, dark band in the middle of the figure… The worst way to learn to light.

  7. If you're not using any ambient light, the ISO and aperture are in fact the only things that matter for exposure. The flash duration is much shorter (1/10,000 second on some) than the shutter sync speed.

  8. I just use my old Minolta Flash 5 meter and just turn off the heads I do not want to fire and get a reading and my ratios. I can do this very fast. My old way seems faster than your new meter system. To bad they do not make Minolta Flash meters anymore. Mine has lasted me many years.

  9. So it measured f/16… I'm not sure that I would use my lens at f/16, but alright, I can live with it. The thing is, how do you know from the light meter which shutter speed must be used? Surely, the aperture is not all there is to it.
