To TTL or Not to TTL Webinar

Off-camera flash done two ways. Find out which style might work best for you!


When adding light to your portraits, it’s clear that off-camera flash produces the most natural and beautiful results. The question that remains is how to best control the flash. Should you use your camera’s TTL metering system or is it best to take control and go full manual?

In this video Webinar presented by PocketWizard, guest photographer Rick Sammon joins host Joe Brady as they do an environmental portrait shoot using both methods. Rick is a master at making TTL off-camera flash easy and effective while Joe prefers full manual control for consistency and repeatability.

Which style is best for you?

Join us for this friendly battle between Rick and Joe as they each show their process for controlling off-camera flash for environmental portraits. Take advantage of the live chat as Rick and Joe will take your questions and discuss the features and benefits of each style. You may choose one side or the other, or perhaps even combine both – but whichever way you decide, this will be a fun and informative presentation!

    To trust your camera or not is the question. While TTL and its subsequent variants works well under diverse lighting conditions it is likely that manual flash with a good light meter is the way for consistent flash exposures. But that depends on situation shooting. Portraits, formal wedding groups would clearly benefit from manual settings but in a fast moving environment it has to be TTL. For environmental shots, it is full manual exposure with a trusty light meter. No TTL for me because lost highlights cannot be recovered even in RAW shots.

    In this TTL webinar, it was stated that when using TT1 and TT5 units in TTL mode, the system thinks that the flash is with the camera and if the camera distance-to-subject is different than the flash distance-to-subject you need to compensate and lower the flash output in order to get the correct exposure. Is that correct? I always thought that the reverse was true. I thought that the TTL system calculates the flash output as if the camera was with the flash (no matter where the camera actually is) so that the subject is properly exposed. Which is true?

      Hi Bob,
      Let’s clarify some points in your question! When a TT1 or TT5 is on the camera, it thinks there is a flash there – that is just so it will send up all of the data to converse about exposure which can then be sent to the receiving unit. If the off-camera flash remains the same distance to the subject, you still may need to compensate for the flash output based on the framing/cropping of the image in the camera and the tonality of the background – the camera is still doing the metering here, not the remote flash.

      For example:
      You have the flash 5 feet from the subject and you frame in your viewfinder for a headshot – you are 10 feet away. That will be “exposure A” – let’s say that the TTL system get the exposure perfect for this one. You then step 20 feet away, but are using a zoom lens so that the relative framing/cropping of the subject remains the same. The exposure will be exactly the same, “exposure A” because the same tonalities are in the frame and the camera’s metering system sees the same relative brightness.

      Now you move 20 feet away, but you decide to go a bit wider and include more of a dark background around your subject. The camera’s TTL system is now going to see a darker “average” in the scene and decide it needs to add more light – this will most probably result in a face that is overexposed – that is where you would have to lower the flash output. Conversely, if the extra background added to the framing was lighter than the subject, the TTL system would see too much light and cut back on the light output. In this case you might have to increase the flash contribution.

      Hope this clarifies things. Let me know if you have any other questions!

      Best regards,
      Joe Brady
