This is probably THE most useful video on the internet for photographers. Thank you for giving me a refresher course that I can watch over and over again to keep this information fresh in my mind ! You are an EXCELLENT teacher!
i guess im asking randomly but does anybody know a method to get back into an Instagram account??
I somehow forgot the login password. I would appreciate any assistance you can offer me!
I have the entire video of this class - Purchased the whole course. This is MOST amazing and MOST helpful course ever! If you really want to imporve in your light and photography, purchase this course and beleive me, you will imporve your photography and take it to next level. Highly recommanded.
How can I buy
In all my years as a photographer, never saw a better explanation of the Aperture/Flash relationship. Thank you!
So you don’t read enough
Excellent explanation but it is noteworthy that changing your aperture and adjusting your flash as mentioned will only keep the exposure correct the same if there is zero ambient light. If there is any ambient light, then as you open the aperture the sections of the frame not blasted in flash will brighten while the subject (hit with flash) will remain consistently exposed. This is why you could also adjust your shutter speed to help control the ambient light. Since the flash is so much faster than the shutter, any shutter speed changes below the sync speed will control the ambient light exposure
EXACTLY what I was going to post, thanks for saving me the trouble. To be fair, that point may have been made in another section of the video (this looks like just a snippet).
Adjusting the aperture and flash power is going to produce the wanted exposure no matter how much ambient light there is. The shutter speed is what's going to regulate the ambient light.
Excellent, clear explanation on f-stops to flash power levels. Thanks you, Zack for sharing this!
thanks Zack! just what i was looking for to wrap my head around!
COOL! THANK YOU ZACK!
I have finally nailed these ratios. And because of this video, I know now how to set my camera in increment of f-stop with respect to my Speedlight and how the Shutter and Aperture change with respect to each other. It's good to memorize these numbers that Zack is making reference to but by setting my D300 to 1/2 Steps for normal shooting and for Speedlight I use 1-Full-Stop increment to match the Camera to the Speedlight; in turn, all this become simple. Cheers to You Z!
Thank you for your great explanation! Very helpful.
and that's a fantastic explanation i have ever had. i am so glad to find your video and also glad for you being on TH-cam and help people who needs a detailed explanation. If there was a chance to hit the like button more times then i would have smashed the line button :P
Just purchased two speedlites . What a great video!
"praying and spraying" hahaha, awesome lingo Zackman. Thanks for sharing your knowledge on flash/aperture relationships.
Super great explanation! I've been photographing for years, less so with a flash and I am sometimes unsure how to work with the numbers. Not so much anymore. Thanks)))
Excellent explanation! thank you!
Thanks for the explanation!!!
Thank you, you make my life so much easier!! 😌
Very useful information. Thank you sir
Thanks zack. Life lesson learnt.
Very good makes understanding lighting simple
Great explanation thank you !
Muy bien explicado. Muchas gracias.
Fucking Yea ! ˝Im shooting at f16 but i want to shoot at f/4˝ ... that explanation is what i couldn't find in any other fansy tutorials .. explained , thanks !
Wow this answered so many question. was just spraying and praying before this video lol.
Exactly what I was looking for
@ptlofts ...if only there were a way to search for these answers. Damn you Zach Arias for not spoon feeding me EVERYTHING I need to know.
Daylight vs. Flash is some engineer's best guess, use a gray card to establish your WB. Too dark to focus? Hot lights, or bring a flashlight.
Photography is about problem solving. Start solving some problems for yourself, and you'll be amazed at the creative solutions you'll come up with...or not.
Wowww this is wonderful ❤️
@ptlofts Best way to understand WB is to shoot the different settings under different light conditions.... outdoors in open shade, sunlight, indoor natural light, incandescent light (tungsten) and flourescent. Use all the WB settings to see what you get. Now do the same thing with Flash. Best way to get to know your equipment is by using it.
As for Focus.... AF uses contrast margins - use a sharp margin (eyeball) to get sharp focus, a soft margin (nose or lips) will not be so sharp.
Thank you ❤️
@8element. The shutter speed has no effect on the exposure of your main subject as the flash happens much much faster than your sync speed. The only influence that a long shutter will have is to burn in a background that is not hit by flash. The size of the aperture controls the amount of light in flash photography.
Whenever I take a single or group portrait in studio flash, I set my ISO to 400, shutter speed at 1/125 and my F stop at F/10. Then I use my light meter on a subject to measure and adjust my strobe lights until I get the reading of F/10 on my light meter. When everything is finally set up correctly, I let my subject hold a Colorchecker Passport next to their face and take a photo. This photo will be used as an adjustment for white balance and color correction in Adobe Lightroom. That's it !
AMAZING info!! I'm trying to learn to not be intimidated by flash and this explanation is REALLY fantastic! I screenshot the chart to keep on my phone's notes app for whenever I'm on a shoot. Keep up the great work Zack and B&H!!
Hi Zack I wonder if you can help please. I'am an owner of a Nikon D850. I intend to use off flash camera. What radio controller n receivers will you recommend.
Many thanks.
Never seen something useful as this! Great video!!!!
how about the distance between the subject and the flash if you shoot for wide like couple in the sunset, and i need to shot a wide.
Cool vid!
btw, I don't even own a speedlight yet,...but when I do, I'll at least be one step ahead. lol
Or one stop ahead
absolutely
How is f/16 to f/11 one stop? If I half the light on the flash, I have to double it in aperture (or ISO or shutter speed). And doubling the aperture from f/16 means you have to go to f/8.
Look at it this way: if you are on f/1, that's focal length divided by one. f/2 means you divide the light from your image by two. Means half the light coming in. Means you need double the light coming from ISO, shutter speed or flash.
Did he made a mistake or am I completely wrong. And if so, why?
Coool great tip
Here's a little tip. when using flash (speedlite) indoors, I find that at the lowest power 1/128 I need my aperture on my 45mm f/1.8 at 5.6. Now, if I want to shoot at 1.8 but my light is at the lowest power, then I need to use a 4 stop ND. This will stop down the light 4 stops so my 1.8 aperture will now have the same light coming throiugh as if my aperture was 5.6 while having a shallower depth of field.
Q. What if we don't use flash at all ? since we are already getting proper exposure
Most modern cameras and speedlights have HSS (high speed sync) which allows the photographer to adjust and correctly expose your subject without the use of ND filters. Focusing indoors with a 4stop ND filter can be challenging to say the least, even with the aid of a tripod.
Another alternative is to diffuse the light thereby reducing the power of the flash output.
Photography is about reading light... and learning the language is paramount to success. Practice practice practice. Isn’t that what doctors do?
Fantastic!
I have a question though. We have some Hensel flashes (I don't have the exact make in mind) and the intensity scale reaches from 5.0 to 10 in .1 steps... Does anyone by chance know if a 1.0 step is 1 stop or what is?
1 step is usually one stop, but you'd want to check the manufacturer's website for more info (specifically 'energy range'.) For example, a Profoto B1 has an energy range of 9 f-stops and can be dialed in by tenths of an f-stop. If by chance you were shooting at f/32, without changing the distance from the subject to the light, or changing the modifier on the light, or changing the settings on the camera, the B1 could drop in power and allow you to shoot at f/2.
I've been scratching my head silly trying to resolve this exact issue. My 400ws strobes power output is from 5.0 to 10 in tenth increments also, and has a power range of 1/1 through 1/128. One step does not seem to equal a stop as LI G indicates, although thanks LI G for the advice- perhaps it is the case for some models. I'd love to know how this relates to my strobes, and yours bruchpilot, have you come across an answer?
it's very helpful video for everyone thank you for guiding people.
This would work if no diffusers or reflectors are used. Once you reflect or diffuse the light, you’d need to adjust again and this wouldn’t work. Right?
great
better than my sub lecturer.
The best out there!! Great vid.. thanks!
Okay so that means that if the exposure needs to be adjusted it is easiest to make changes with aperture or strobe power. If possible then we should avoid messing with the subject to light distance? If we do that we would be messing with inverse square law. I guess that would be the next video and a whole another can of worms.
Finally.
MAAAN THANK YOU
@ptlofts John green said that white balance doesn't matter, set it to auto and shot raw. you can change the white balance later. focus issues depends on so many things, there's no one answer to that question, it all depends on how much light is in the room and what you are trying to capture. like zack said you have to learn your camera and gears to understand what works. there's no one answer for that.
How about the Shutter Speed / exposure time with HSS flashes? ;)
that can be experimented as per the situation - this made my life so easy
I missed something in the end ...
what about the ISO relationship :D
ISO Shmi SO
Zack,
regarding to the inverse square law and flash guide number rule... your method is incorrect.
So genuine explanation .:p
Sorry for the inconvenience but this explanation someone has to translate text ... I understand very little because I do not speak the language but understand something and looks interesting .... note: THIS IS WRITTEN IN GOOGLE TRANSLATOR SO SORRY IF MY WRITING CREATE ANY INCONSISTENCIES ... thanks
now he needs to explain shooting with these outdoors against bright sunlight, which would require full power to compensate sunlight... but wanting to use a wider aperture.. time to equate distance of light into the equation and bust out the ND filters.. ;-)
This is a 'studio' lighting workshop.
More than 5 minutes to explain that?
I mean, I guess
1 stop = 2 apertures or shutter values
This could have been explained in 30 seconds.

.salüt.
fraud
Wait till u go outside .. this simple explanation won't work in sunlight. need to factor in shutter speed in relation to aperture. and yep break out the ND filters.
I don't think sunlight was in the title so...
+STEPHEN POLWART This was for indoor shooting!
Umm, this a 'studio lighting' workshop.
So what is the point of this video all what he said is absolutely basic stuff
