AdoramaTV Presents Digital Photography One on One. In this episode Mark walks through the differences between using constant light and light from a flash. Join Mark in the studio for a hands-on demonstration that shows how constant light produces different results than light coming from a flash.

the shuttr speed says u was at 100per sec..and u say u was at 2000 per sec shuttr speed to " freeze" the item the gal is jerking.
Marc, you're awesome! Love your videos! …but I'm pretty sure AC in your comparison chart refers to alternating current (power consumption) and nothing to due with air conditioning 🙂
Should have had her flick her hair not a scarf! Nice video though. Constant lights are good for film though..
So strobe lights just allow you to use a faster shutter, lower iso, and high aperture? I've never used one, but this question came up when I was looking at some portrait art. How do photographers get started? I want to practice but not exactly sure how to obtain clients. I'm assuming its just like film and tv by just giving out free work?
Thank you so much, this is my first time seeing one of your videos, but I can already tell I'll be watching a lot more – thanks for referencing related videos, it's very helpful.
Nice video but you forgot to mention the portability of these two lightsources. You either need to have wall socket or a battery pack for constant lights and battery packs for these things are WAY more expensive than flashguns and some batteries 😉
I had an old konica minolta Semi-SLR camera, way before my SLR days. I know SLR shutter speed is limited to flash sync speed, my pentax's are normally around 1/180th. My old Konica Minolta semi-SLR allowed me to run the strobe at 1/4000th of a second and capture some CRAZY images of running water and stopping everything entirely solid, why is this? I am guessing the teeny tiny shutter in the non-SLR is able to move a lot faster and sync with the flash output.
Super duper video. I wish I will become a Mark in my after life.
Shallow depth of field can be achieved with strobes. Just select the aperture for the desired result and adjust the strobes power output to give you a proper exposure. Using a handheld light meter makes this easy.
good
hehe 🙂 thats not really like that 🙂 when they are on constant, its worth probably about a 100 maybe 200W bulb.. 🙂 but I don't want to evaluate them from a distance…….
that model was gorgeous, and she posed beautifully, she looked beautiful in every photo
You called her Lichelle first, then Lydia later on O.o
Im sure 1/100 is correct. The whole point of that section of the video is to explain that you can shoot at 1/100 and still freeze an image with a strobe. I use this method all the time. Interestingly…you can set your shutter speed to 5s if you are in a pitch black room. Flash your strobe a couple of times while pointing the camera in different directions. The final image will be a composite of the flashes and it will have a cool ghostly effect.
the 1/100 is probably the correct answer. as Mark explained, your shutter speed, in this case, is irrelevant b/c with his f/10 and 1/100sec, the exposure is pitch black. the only thing the camera sees is the quick blip of the strobe which is why he as able to 'freeze' the motion.
That's not true either—my old D70 will sync at 1/8000 (which can be shorter than the flash duration), as will most point-and-shoot compacts. What matters is the type of shutter. Cameras that use a focal plane mechanical shutter alone, like most current 35mm and APS-C DSLRs with CMOS sensors, obtain high shutter speeds by exposing only part of the sensor at a time. Leaf shutters (mostly medium format) and electronic shutters (compacts & some old DSLRs) can sync at all speeds.
Totally true essellar. Only the top cameras for studio like hasseblad can achieve up to 1/800s flash sync. I mean for studio as for outdoors it wouldn't be the best choice IMO.
In addition to what lpfuria posted, a shutter speed of 1/1000s would be faster than the X-sync speed of the camera, so only part of the frame would have been exposed. In order to use shutter speeds higher than the X-sync speed of your camera, you need to use a dedicated flash with focal-plane sync, which fires a number of times during the exposure. See Episode 17 in the series for more information on sync speed.
that's possible and usual as the only light source was from the strobe. he could even slow down the shutter speed at least 1 stop and it wouldn't get any difference — he had showed the black frame when the flashlight was off. the real speed of a standard flashlight power supply is 1/1000, a real good one can achieve 1/8000 like broncolor ones.
at 9:34 in the right picture the information says the strobe frame was shot at 1/100 sec. But that's impossible. I think that's a typo. It should say 1/1000 sec. Thumbs up so people see.
The degree symbol (tiny circle) is not used with Kelvin, though it is used with Celsius or Fahrenheit. So there's nothing called XXX degrees Kelvin.
great info as always, mark.
say, how many short-sleeve polos would you say you own?
I really love your videos and they really are very informative. Thanks a lot.
But, it's wrong to say "5200 degrees Kelvin", it should only be "5200 Kelvin" (no "degrees").
I've never tried that feel like an idiot now haha but than will give it a go cheers mate
Time is money. If you're doing a photo shoot of a high paid model/talent then you can't waste any time calibrating your setup to get the desired image. Therefore, a dedicated light meter can save you precious time and money.
You can create a shallow depth of field with a studio strobe as well. Just lower the strobe's output in conjunction to increasing shutter speed. If that's not enough, you could also use neutral density filters.
Great video, the only thing I noticed was that the pro foto light had a soft box on and It would have been a little more realistic if both lights would have been bare bulbs( just like the hot light), I'm just saying to be fair to the tutorial. Thank you, beautiful images though…
She's the most beautiful non asian girl I've ever seen !!! the review is really great thanks so much for the info mark ^^ .
@DrLB85 yes, watt-sec is watt consumption in 1 sec… multiply it up all the way to 1hr, and you get the 1hr consumption… but it fires for a crunch of a sec.. so it's not really "fair" to judge them for that :))))))
Extremely useful 😉 thank you
Thank you! I really enjoy your shows..you make it so easy to understand.
Great vid! Is that the Plus iii?
I've seen much longer videos that don't say half as much as this one. The chart at the end was the icing on the cake. Thank you!
Sorry Lachelin
Great video Mark, I think I'm in love with Lydia, She is Dreeeeaaaaammmmmyyy. Stunning
fantastic again, best photography show on the web
The crisp light of the Arri looks splendid!
