Thanks for clear logical messages in this video. One point - the flash triangle is - ISO, F-Stop and Flash power. You made no mention of ISO and instead talked about shutter speed which is OK in a fill-in situation where natural light needs allowed for but not in pure manual control you were describing.

I hope that make sense. I am glad I stumbled across your videos as you explain things so well and I am new to photography gear. 🙂 i do most of my captures outside but do use the flash and sometimes need a reflector

Thanks and great question. It’s one I had in my closet for years until I moved into this new space and had room to set it up. It’s just a standard painted muslin backdrop and it’s massive. Maybe 10-12 feet wide and 20 feet long.

@chandreo 3 жыл бұрын

Again great video. Can I try to explain it in a different manner? Here it goes: A light meter of the reflective type (all the ones in the cameras) want to turn everything gray (put your camera in auto everything and take a picture of a black paper filling the field of view, do the same with a white one and now put them in the middle next to each other in the centre also filling the filled of view, the 2 first shots will be more or less gray and the third will have white and black very distinct, as you gave the meter the information that there is 50% black and 50% white) with the incident meters all that matters is the light falling on the subject and not it’s properties. Try it, it’s the best way to understand it. Hope that also helped! Cheers, André

@onlysublime Жыл бұрын

If people were willing to learn strobes and flashes, they would also find light meters essential. It's just that strobes are so expensive for most people and cumbersome to carry and set up so people don't see the need for light meters. But the meter takes all the guesswork out. The meter literally tells you how to set the camera settings based on how powerful you set your strobe.

@davidpine4817 3 жыл бұрын

Thanks, David. This was one of the better flash meterings tutorials out. What could help many photographers would be to provide a similar tutorial on 2 to 3 light setups showing lighting ratios in 1/3, 1/2, 1/10, and full stops of light. Some people think I am crazy for using a light meter on almost everything I shoot but I feel I get better all-around exposures than just eye-balling it.

@Crazy_Dashcam_Videos 8 ай бұрын

Now what if we already have the camera exposure set to expose for the background? And then we want to get the correct exposure by only adjusting the flash power?

@leonardobaldenegrodiaz4503 Жыл бұрын

I have a doubt, I have several exposure meters that were made at the time when the analog photo was what ruled the market, a digital minolta, an analog sekonic and a polaris, basically the minolta and the polaris are the ones that arrived to use at some point. My doubt is that on some occasion I took digital photos taking the measurement with those exposure meters and when I put the exposure information that the exposure meter marked on the camera, mostly the images came out somewhat overexposed, so I stopped using the exposure meter and Guide me more by eye, so I wonder if the exposure meters built in the 90s have something to do with the new exposure meters in the digital age? Do digital cameras work the same with old exposure meters? Greetings from Mexico and I hope you can solve my doubt.

@Karlita91100 3 жыл бұрын

New to flash photography here! Could someone explain… I feel like aperture is a creative choice re: depth of field. When you use aperture to control the amount of light, the depth of field changes. Wouldn’t a photographer have a depth of field in mind that they want to use for creative purposes? As a example, if you’re photographing a large group, and the light meter tells you to use 2.8, the depth of field would be too shallow. Why adjust the aperture rather than the flash power? (I realize photographers adjust flash power too, but many tutorials tell you to change the aperture). Would this be when a photographer doesn’t care about depth of field? I’m a natural light photographer so I always care about depth of field. Thank you!

@DavidBergmanPhoto 3 жыл бұрын

You are absolutely correct. Depth of field does matter and you could raise yourself flash power if you need a certain f-stop. It’s always a give-and-take though. You might already be at full power on your flash (a speedlite in a large modifier, for example). Or you might prefer to keep flash power lower for faster exhale time and longer battery life. In either case, you’d have to either open up your aperture and/or raise your ISO.

Thanks for the video, David! Quick question: why did you point the meter towards the light, not the camera?

@DavidBergmanPhoto 3 жыл бұрын

Both methods are useful, but different. And it really depends what you’re shooting. I want to see how much light is coming from that flash. So I point the meter directly at the it. In my mind, I can determine if I want to see the full power of the flash from the camera angle or not. Actually, this may need more explanation and would be a great video. Submit it at www.AskDavidBergman.com and I’ll do it!

@AlexXPandian 11 ай бұрын

You made an accurate statement that shutter speed doesn’t matter when it’s purely flash photography. And then you proceeded to say you are going to fix two pieces (of 3) of camera parameters at 200 iso (okay) and 1/250th of a second. Where did this magic speed come from ? Please don’t say it’s the sync speed limit. That limit just tells us what’s the fastest shutter speed we can use while not missing the window of the flash strobe.

@MrJueKa Жыл бұрын

Sorry, but somehow this is logical and self-explanatory, at least for me, because if you use an external flash meter, then you should also set the determined values, here the aperture, manually on the camera, otherwise there will be incorrect exposures, namely too bright or too dark , that's not confusing "rocket science". In analog photography, object measurement should be preferred for negative film and light measurement with the dome for slide film, basically to get a proper exposure for each film material. The reason for this is that slide film in particular is exposed more to the lights and is therefore exposed with a bit more contrast, which looks quite good in general, but that is also a question of personal taste.

@Strongbear2013 3 жыл бұрын

Thanks for the helpful video. With TTL and then a TCM button like on the Godox XPro flash trigger, would that cut out the need for a separate flash meter completely since it would allow you to take the reading you've had in TTL and covert to manual? But what happens if you have a second speedlight (eg used a rim/ hair light rather than a key light) that doesn't have TTL and is only triggered either by the flash trigger in manual (or if it is an older speedlight and uses a slave unit that only fires when another flash fires?) Would that second flash require a separate flash meter to meter out the power output properly? Or would the flash trigger already have that covered? I'm a little confused how it would work.

@DavidBergmanPhoto 3 жыл бұрын

The external meter doesn't automatically set anything in your camera. It just tells you how much light is coming from the strobe and then you can make the decision on how to set your exposure. In either case, you are still gauging the exposure based on the back-of-camera viewfinder. As I say in the video, that may work fine, but for the most accurate information, using an external meter will give you more information that you can use to set your exposure.

@AndreiIvanov7b3 3 жыл бұрын

The best example of work with multiple flashes on this channel is any episode of On Set with Daniel Norton, IMHO. If your flashes are not TTL, meter them each separately with external meter as David suggested, then adjust accordingly, if you are shooting digital you can see the result immediately. I would probably get key light set first (and get it to manual), then move on to other groups as a ratio to what you get from key...

@DavidBergmanPhoto 3 жыл бұрын

@@AndreiIvanov7b3 Either way works, but I actually prefer to get my background looking good first. Then add in the key light(s) on my subject. That way I can see if the front light is messing up the background and adjust accordingly.

Y'a go figure why there is so few brands making Flash Meters and why even the cheapest one is still kind of expensive for what it does. I so wish Godox would have put TCM on their latest X2T transmitter, instead these idiots made it so you must get the older and super bully Pro version of almost the same price just to have this functionality (-_-)
