I have been watching several TTL vids and yours by far is the fastest...and easiest to understand (around 70 seconds) . You are the master of explanation. Thanks for putting together the tutorial for us amateurs!
A third mode, usually known as "Auto", has a photocell on the flash unit to control output. It came before TTL was invented and is found on older units (c1980-2000). It did not depend on camera brand. Some of the those units had all three modes (ie Manual, Auto, TTL). The Auto mode seems to have been dropped from modern units, cost saving I guess.
It's good it's good to point out that TTL works better when there's mid-tones in the background. If the sun or bright objects or dark objects show it sets off the ttl. I had to go manual many times.
Great video. Question do u set your camera exposure first then the flash will automatically set the power automatically? Or do u under expose your camera and the flash will determine the amount of power?
Generally with TTL flash It is plug and Play. You just put the flash on and go. If you are shooting in Manual mode on your Camera and your flash is in TTL mode the Flash will do all the calculations needed to provide the correct exposure.
If you want the scenery around and in the background to show then you set your camera to expose it as you desire according to the ambient light. Flash is then just a little addition to help bring out the subject to either be in better balance with the background or stand out even more so first just get your exposure right as usual then add flash if needed. You would only underexpose and compensate with flash if you were trying to darken the background.
Retarded question but I need confirmation. If camera ExpComp is set to -0.3 and Flash TTL ExpComp is set to -0.3 too....... the photo will be exposed -0.6? Thank you.
It depends on your camera mode. Since shutter speed wont affect affect your flash output. If you are using apature priorty mode, you would only lose -0.3stop exposure. But if you are shooting in shutter priority mode, you should get -0.6 stop.
I have Metz 32CT 3, It does have TTL. I find there's only one pin for the Canon 5D Mark 4...Works? This flash is vintage one over 40 years. I like Metz flash gives accurate color temperature. Do you think it would 'burn' my camera?
You absolute star! I am a newbie to the world of speedlites and didn't even know that there was a difference between TTL and Manual. I recently bought a second-hand Neewer NW565 and am over the moon with how easy it is to use with my Nikon D5300 - it has made an invaluable difference to my photography! I am in the process of getting a spare flash (and taking care of the budget) and will get another TTL (most probably another used Neewer). Thank you so much for this easy to understand video...you made it so easy for me to know what to get for my next flash! x
I just purchased a Godox TT350 and truly enjoyed your video. You saved me quite a lot of reading. Excellent information for a novice to understand. :-)
Great explanation. Thank you for that. Question: if only your master flash is TTL, will it control the output of the slaves, or must each of the slaves be set manually?
. so if the camera is all in manual setting does it mean the flash output will compensate for it and not the other way around? does the flash ev on camera meant for the camera built-in flash or the mounted flash takes over? and then there's another flash ev on the flashgun itself that adds to my confusion .
Is it acceptable to bounce Canon TTL flashes, coz many times I have encountered a issue that, when I use a TTL mode on my Canon 430 EX II and bounce it over the ceiling I get a underexposed shot but when I point the flash directly on the subject it exposes correctly e respective of the flash exposure compensation inn TTL mode. But certainly when I bounce Nikon TTL flash in B-TTL or I-TTL mode i don't encounter this problem. Could you explain the mechanism both the brands?, Never tested other brands except Digitek n Simpex! Thanks in advance!
Ameet Pawar I personally haven't had much experience with Canon TTL flashes. I mostly purchase third-party flashes. The only Canon ETTL flash I own is the 320EX. Based on the 320, the bounces do tend to be underexposed, albeit slightly (around 1/3 stops). Hopefully someone with experience on Canon ETTL flashes stumbles upon this comment and shares their findings.
Ameet Pawar I use the Canon 430 EX II for bonce flash all the time and the only time I have the problem you are talking about is when the flash runs out of power. If the ceiling is to high or it is a darker color I will have to increase my ISO in order to get the correct exposure. I have also found that if you zoom the flash in, you can get an extra 2 stops of light output from it or at least you can get 2 stops more light where you need it.
Great toot. I use a canon eos rp with a third party ettl flash system. How do you control the flash from the camera? I’m yet to figure this out. Keep having to manually change when metering. Thanks. 😊 Subscribed.
Hi i have just bought the Yongnuo YN 24 ex, it doesn't work at all when the camera is on manual mode plus according to manufacturer when the flash is charged the indicator light should be green which never happens it is always solid red and I am using brand nee fully charged panasonic eneloop pro aa batteries. Any help with that?! Ps i have the white balance at flash and my camera is canon D700. Thank you
Thanks. I'm finding using flashes in general a real bore. I never get pleasing results from them and have had my YN560 sitting in my bag for a decade. As someone getting into wedding photography now I'm thinking I need a good flash for the reception which has challenging lighting at the best of times.
Thanks for the nice video. I'm still in a dilemma. I have a flash model YN685. I plan on buying another Yn flash. Which in your opinion is a better flash of the YN600 or YN685. I want to connect these 2 flashes with one wireless trigger Which model is a wireless trigger. Yongnuo YN685 vs YN600 to the Canon 600 hopefully there will be time for one answer.
I own a Canon 5Dmk3 w/600EX-RT speedlite. Using ETTL I get correct exposure with an indoor bounce flash at f4 for example. At a higher f-stop, say f11, I must power up the flash to compensate, ETTL won't do this for me, why?
Damn! Your're good!!! I'm in the video business for over 30 years and now have a photo headshot gig...so am now learning how to use a flash for 1st time ever. Thank you, thank you, thank you!!!
It was great the way you drew the picture showing pre-flash bouncing and going back into the camera so it could calculate the correct flash level. Thanks for the info, now to decide which third party flash to buy in 2020 :)
Thank you. Now I have some idea at least of what I'm trying to do. You did a great job of explaining this. I will be sending several of my friends to check this out, instead of trying to explain it lol.
This is very informative and easy to understand. My head has been spinning trying to figure all the features to TTL's. Thank you.
same here
Finally someone can explain TTL to me.
Thanks for that detailed explaination :) ! subscribing now.

I wonder if you can still use old speedlights that has an AUTO mode, on digital cameras?
You articulated this beautifully, thank you so much.
Thanks
Thank you for seriously actually knowing your stuff man! Im a video guy so this is great info.
It's good it's good to point out that TTL works better when there's mid-tones in the background. If the sun or bright objects or dark objects show it sets off the ttl. I had to go manual many times.
Never had this problem

Wow, that's a very thorough explanation. Thank you so much!
FYI:
I-TTL = Information (Nikon)
E-TTL = Evaluative (Canon)
P-TTL = Preflash (Pentax, the TTL pioneer) flash metering.
Wow well explained 🙂
Retarded question but I need confirmation. If camera ExpComp is set to -0.3 and Flash TTL ExpComp is set to -0.3 too....... the photo will be exposed -0.6? Thank you.
That's correct, the photo will be 2/3 stops underexposed.

Still valid in 2020. Thanks a lot for the concise and clear explanation.
Very clear explanation. Finally I get it. Definitely subscribing.
very well explained.straight to the point. thanks
Thanks for this video, I like how you explain the relevant concepts concisely yet comprehensively.
Thankyou so much for explaining in more depth what this is, very helpful:D

what is your suggestions for canon 760d
?? ?? thanks and more power
Thank you
Great video, your really made it clear! Question: if the hot shoe of the camera has one pin, like Sony a7sii, it means that you can't use a TTL flash?
Fnally, someone that knows how to explain what TTL means and how it works and why it works the way it does. Thank you so very much for the video!
perfect explanation, thank you !!

Always enjoy your videos. Informative and well done. Thanks
WELL DONE!! Very good explanation. THANK YOU!!!!
.
so if the camera is all in manual setting does it mean the flash output will compensate for it and not the other way around?
does the flash ev on camera meant for the camera built-in flash or the mounted flash takes over? and then there's another flash ev on the flashgun itself that adds to my confusion
.

ZY Productions Thank you for useful information. Which third party flashes u prefer for the Nikon DSLR camera's on a budget of $150?. Thank you!
Most my flashes are Yongnuo flashes. They aren't the absolute best quality out there but they are reasonably-priced and get the job done.
Yongnou any specific model u suggest. Thank you for the valuable in formation u shared!.
You should demo though.
Great toot. I use a canon eos rp with a third party ettl flash system. How do you control the flash from the camera? I’m yet to figure this out. Keep having to manually change when metering. Thanks. 😊 Subscribed.
Thank you for your simple explanation bro. Really helped out
Superb presentation. Thanks.
Thank you very much! Very well explained :) Greetings from Sri Lanka.

LOVE THE INFO - Thank you so much for this tutorial segment of Flash photography
Amazing explanation, thank you so so much! :)
Broke it down perfectly! Thanks!
Thanks for the simple and clear explanation!
Excellent - subbed. Now I have to spend MORE $ on a flash unit - darn ; )
Very simple and very helpful. Thank you!
thanks for this video, really well explained
Thanks for the info. Short and on point.
But why does TTL mode (on triggers like the Xpro) have a power adjustment option? I thought TTL was supposed to set the power for me?
Excellent video, thanks
Thanks for this
Thankyou young man
Always buy a top end flash. Quality is always there.
Hi i have just bought the Yongnuo YN 24 ex, it doesn't work at all when the camera is on manual mode plus according to manufacturer when the flash is charged the indicator light should be green which never happens it is always solid red and I am using brand nee fully charged panasonic eneloop pro aa batteries. Any help with that?!
Ps i have the white balance at flash and my camera is canon D700. Thank you
I am in the very same situation! My T5i does not recognize my YONGNUO YN560-IV SPEEDLITE.
Thank you so much!!! This was very simple
well done explanation

Hi , what is the difference between iTTL and non-TTL AUTO Flash modes in Nikon SB-910 flash? The both modes are using “monitor pre-flashes”.
why ttl flash is not good for interiour photography?
Your english is perfect, congrats!
Thanks for the nice video. I'm still in a dilemma. I have a flash model YN685. I plan on buying another Yn flash.
Which in your opinion is a better flash of the YN600 or YN685.
I want to connect these 2 flashes with one wireless trigger
Which model is a wireless trigger.
Yongnuo YN685 vs YN600 to the Canon 600
hopefully there will be time for one answer.
Meaningful, well explained and easy to understand... thanks for the great work...
very thank you
Great explanation - thank you!
Explained thoroughly. Thank you 🙏🏽🙏🏽🙏🏽🙏🏽
2:17 very artistic
Excellent! Thanks

If I'm using a 9x9 softbox on my flash will TTL still work? Do the sensors on the front of the flash have anything to do with TTL?
a good explanation thanks
Hi what settings should i make on my Nikon D5100 before using my Vivitar df-383 flash ?
Thanks
What flash will support on canon T7
Damn! Your're good!!! I'm in the video business for over 30 years and now have a photo headshot gig...so am now learning how to use a flash for 1st time ever. Thank you, thank you, thank you!!!
beautifull explanation!!! big up !
This was might useful and simple
I am automatically happy to see you are doing a video on a topic I've searched. Thank You.
It was great the way you drew the picture showing pre-flash bouncing and going back into the camera so it could calculate the correct flash level. Thanks for the info, now to decide which third party flash to buy in 2020 :)
im dumb, why wont my godox flash change focal lengths or let me set it to auto mode?
Thank you. Now I have some idea at least of what I'm trying to do. You did a great job of explaining this. I will be sending several of my friends to check this out, instead of trying to explain it lol.
Nicely done, thank you.
Thank you so much for this video, I was overwhelmed as a newbie to studio photography
You sir, are awesome. Best explanation so far. Thank you 🙏✨️
Great explanation!
Great explanation
Hi! Will the ETTL and other features work on the Yongnuo YN568 EX II work with the Canon 6D Mark ii?
This is real good!!!
Brilliant explanation thanks.
Now I know where I am going, thanks for your clear and limpid tutorial on the TTL pale. Respect!
Thanks. I wish I had seen this before buying a manual flash.
Me too... But ya gotta start somewhere I guess
Me too, but I plan to return my manual flash for a TTL flash.
Good news, you can have more than one flash. In fact, 3 is a good standard.
Hallelujah, Thanks a lot, Now I understand; Also see other comments below :)
Great info. Thank you.
