For those of you who get into situations where you have limited time to set up, manually light and fine tune it to how you would like, well-known photographer Joe McNally shows how quick and easy using TTL can be when pairing an Air Remote with a Profoto B1 strobe unit. This would be great for event shooters, and setting up for quick portraits. Read on for two other videos on high speed sync and lighting ratios.
In this next video, Joe leaves the studio and shows how he is able to light a portrait, while working against the bright sun, but is still able to come away with an image at a wide aperture using high speed sync. He is able to accomplish this using the Air Remote, and by having a camera with that feature (in this case, a Nikon D4s or D810).
In the third and final video, Joe speaks to lighting ratios in the studio. He uses flash groups to control settings of certain lights at the same time, while keeping his main light separate, shooting in both manual and TTL modes.
