TTL vs. Manual Recycle Times

TPL versus manual recycled times. I'm not gonna keep beating you over the head with this. Well, yeah, I actually I'm gonna keep looking over there with us. Let's talk about this because a lot of people, including our own staff photographers, often have said to me pie Other people say that titi l recycles just as quickly as manual, and I say to them it does not. In fact, if you think about it logically for one second if your cameras firing a pre flash and then flashing afterwards, it would use a little bit of power for that pre flash, would it not? And they say yes. Don't you think that takes a little bit about her power? Yes. Don't you think that would require a little more recycled time afterwards? Because your flash fired twice? Yes. So don't you think that you re cycle time would be a little bit slower with t t l versus manual? I don't understand. I don't understand the logic behind it. So what I did was actually did a test. I used the canon 5 80 x two. We ran a simple test. Just ap...

prove this point. Let's talk about how we did it. So we're using the 5 80 x two. We use standard Duracell and any loop rechargeable batteries. We ran the test three times with each, just to make sure, like we didn't want anybody to doubt the results. Okay, So each time we use brand new batteries, either freshly recharge any groups or brand new Duracell's with each test procedure. Here it was. We had a Libya sitting there. We set up a little clamshell lighting set up. We had the camera on a tripod, so that way, nothing would change. Okay, we're using manual and T tail exposures on the flash, and we set those exposures basically to be identical across the board. So that way, when a manual flash fired, it was the same exposure as when the TT all fired. We did a manual test. First we did the T tail test second. So what did that mean? We started manual and then we tested T t l and then went back to manual on the same set of batteries before swapping batteries. The test here was that if basically, we only did the manual test first and then we did TL first people would say, Oh, this is the batteries. But by doing this, we start with manual. So we use the batteries first on manual, the same set of batteries within switched over the CTL to get our reading and the same center batters went back to manual. So now the batteries had been used twice once manual ones. Tieleman back to manual to get our final kind of test results. Okay, so manuals has the third that we ran the same test three different times with each other batteries and with the exact same results. Now the numbers slightly varied, based on how old the batteries were like whether the any hopes were a new set of any loops person old set. But the numbers were identical in the way that they progressed. Okay, so camera settings was of a second F 7.1, and I so 100 that way, we're running a pretty heavy flash. Okay, So under t tl were at plus one and 2/3 for the exploded setting and manual were between 1/2 and 1/4 power. All right, now, once I was all set up, we starting our shots and check us out. This was the result that we got across the board manual would start out extremely quick. We're at 0.58 seconds for the first recycle 0.731 point away, 1.23 and then from there it slowly declines to 1.33 by the eighth shot. When we switch over to T T L, it goes immediately to 1.51 point 68 and it starts dropping. We end at 2.51 on the 12th on T O, then switching back to manual, mind you. Same set of batteries back to manual. The first recycled 0.66 We ended at 2.51 2nd recycle is point 83rd. Recycle was 1.38 and that's where basically stabilizes. We end at 1. after 10 additional shots. Now, at the very end of this, let's not even talk about the earlier numbers. At the very end, 1.66 that's more than 50% faster, like like or 2.51 seconds is more than 50% slower than 1.66 That is a huge difference in recycled time. So does t t l use more power. And does it slow down your recycled time? Yes. If your camera if your flash is firing a pre flashed engage exposure, it will indeed use power. And it will indeed slow down the recycled time If you don't believe me, Run the test yourselves guys, We've done it six times here just to show you and have all the video footage there to prove it and everything. So please take my word for it. And don't waste your time. Let's move on to the next video.

Class Description

Lighting 101 follows in Photography 101's footsteps. Photography 101 takes students up through Manual Mode mastery and provides a foundation in natural light techniques and modifications. Lighting 101 picks up by teaching all about flash and light modification. But, just like Photography 101, we want Lighting 101 to be the most accessible lighting course available. So we teach you everything about flash lighting, light modification, ambient to flash balance, lighting patterns, off-camera lighting and even multi-point off-camera light setups. But, what makes Lighting 101 truly special is that we do all of this with nothing but your on-camera hot shoe flash. Every image shown and created in this course was created with a DSLR and just a single on-camera hot shoe speed light. 

Graduate to the next level of exposure mastery with Lighting 201, Lighting 301, and Lighting 401 with Pye Jirsa.



The best class for understanding light and lighting there is bar none. Pye is an excellent teacher and the quality of the material provides for a rich and very informative experience. Pye breaks down the fundamentals in easy to digest packets and then elaborates as needed. If there is one class that you watch this is it! Worth purchasing and saving for future use. I would also HIGHLY recommend downloading the saving the PDF of slides that accompany the videos. Again, and can't say it enough, this is THE BEST video to lighting on Creative Live. A must watch for the novice and the expert.

This is the best thing that happened to me since I've been into photography. What a lifesaver. Unfortunately I already payed for some courses that are not Pye, but Pye just nails it. Amazing, and kind of a life hack. Thanks again :)

George Gan was well worth your training. I have learned some key lighting techniques from this training. His voice and training is clear except for his attempt at making jokes and should hire a new script writer for your Jokes...ha ha ha ha. With that said, if you are not a professional in lighting, you do gain a lot going through this training from front to end. Remember this is lighting 101 so don't expect too want more technical and complexity, wait for Lighting 201, 301 or 401 ...
