Speedlites: Optical vs. Radio Systems
If you're watching online police pay attention, this is gonna be like super important to you because this will remove a lot of frustrations with flashes. Okay, um there's, nothing more frustrating that you turn on the flash you tried to set up on light pocket that you try to improve the light somehow on your flashes are just not talking to each other and you're just like your clients are like, you know, I mean, so let's not do that let's just know how this works, and then we can avoid this issues, right, honey, let's avoid issues. Here we are, flashes have toe have to communicate with each other in order for them to fire at the same time. It's like speaking english to people that you speak to them, they would speak to you and you respond and you go back and forth. This is communicating with this just like I'm communicating with you, just like nikki and I communicate on breaks. Okay, so there's, two kinds of communications, two main ones that happened the first one is is optical or they...
call it line of sight. What that means is that when this flash fires the light goes out on then this flash says, I see you and then it fires because it seems that one it happened so fast because guess what it happens at the speed of light switches rather quick you know not just pretty impressive you know speed of light time okay so remember optical line of sight the flash fires this one sees that flash firing see said it's just like oh I should probably fire to it fires and then both fights both flashers going your exposure cool the next type of communication is called radio front radio transmission or radio communication that means that he uses radio signals so in other words can I can I get that reflector please in other words there is no need for this flash to see the light off this flash okay it happens automatically so for example let's pretend this reflector is your subject actually I have a model here actually can I borrow you win for a second everybody is this calvin he's modeling for us today that's right I'm still better looking okay I'm still not as tall alright well not everybody wins in the gene pool I guess so um could you stand right in between these two flashes real quick okay call right there and then face this way that that this way right this with cameras can see you in radio transmission the flashes don't need to see each other they just have to this one fires on its sense radio signals to the other flash and it's a few fire now ok that's super important because if you want a backlight him or you want to create rain lighting or something like this his body is not exactly see through some accents so if this fires and hits his body this flash we'll never see that light because he's hitting his body so this flash will just not fire in optical transmission line of sight but when the radio transmission is turned on that fire's on this fires automatically because they're communicating through radio waves if I was to put a war between between the two flashes they would both fired anyway so the only thing you have to remember is this in optical or line of sight the two flashes have toby within they have to see each other in radio their flashes do not have to see each other they can they will just all fire let me explain to you that this is in cannon and aiko now in canon in optical the sensor to receive the signal is in the front so if you're using pan and flashes and you wanted to opt to go line of sight why would you do that? I don't know but if you want to the flash sensor is on the front in nikon a nikon flashes which are really amazing powerful flashes body nikon flashes they put the sensor on the side so I see people trying to fire each other I see people going talk to each other talk to each other but they won't talk they're angry and it's because the sensor is on the other side so if you want this flash to fire on this flash to see to see this one firing you have to turn this one sideways so the sensor hits it then you have to turn the flash ed in the original the russian that you wanted so now this one fires this sensor girls I see you on in the flash fires so this very important a nikon the sensors on the side on cannon the sensors in the front ok last but not least in cannon you have you have radio you have optical line of sight capabilities but this six hundred e x artie flash is also have radio built into them that means that with one unit you can do a line of sight or you can do radio you can put walls behind between each flash it doesn't matter it will fire with nikon you only have optical so if you want radio transmissions so you don't have any problems you're gonna have to put parking wasters on this so what happens this you have to put a transmitter on one of them so here's that population thirty one you put one of them here now this can communicate with a receiver the receiver is there is this one population fifty five so thank you so then this one receives the signal I'm problem fixed okay that's it so now when this fires this one can't be in between his body. Solomon can be between on this communication radio signals, and you will always have success. It will always fire all the time. Okay?

Im sitting in my office listening to Roberto with my earplugs on and I know I have already left 2 reviews but he's so funny…. my family comes into the office asking me "whats so funny" Roberto makes me laugh out loud with his jokes but at the same time, he is SO great at teaching. Im watching for second time to make sure all his good info is ingrained. HIGHLY recommend you take his workshop on Picture Perfect Lighting if you truly want to take your photography to the next level! WOW thats 3 reviews now…can you tell I am impressed

I'm taking a portrait photography course at NYIP online. one of the mentors there recommended the posing book by Roberto. I ended up ordering at the library the posing and the perfect practice book. I fell in love with both books...ended up buying them and signing up here for the year membership just so I can take all of his photos courses. I spent most of my weekend doing perfect lighting course here I am in love with the way that he teaches! He makes something so difficult and challenging for me make sense. I also like that he challenges us photographers to be true professionals. I am thrilled to have discovered Roberto and already noticed my photography is better in the short time that I've been studying him.
