In these videos, Joe McNally walks through the basics of TTL flash, including lighting ratios and high-speed sync. He’s specifically talking about Profoto’s Air TTL system; however, these principles apply to smaller speedlights from Canon, Nikon and other manufacturers. [Read more…]
While that’s nothing new for a third-party transmitter, the receiver unit is a no-brainer for someone who has a bag full of 580EX Speedlites and is starting to integrate 600EX RT units into their kit. Just add the receiver onto your 580EX, pair it with the Laso transmitter (or the Canon ST-E3-RT or 600EX RT) and you have a flash that works with the Canon RT system, which you can now mix with newer 600EX RT Speedlites.

While he demos the Profoto kit, the same rules apply to smaller speedlight kits and other TTL monolights and flash heads. With purely manual flash communication, however, you are limited to the sync speed of your camera (often around 1/200s) and won’t be able to freeze that motion.
Yesterday, I shared a video from Profoto that discussed the benefits of high speed sync when shooting in high ambient light outdoors. In this video from Profoto, we get another look at the differences between shooting with ambient light only and adding layers of light using TTL lighting outdoors mixed with available ambient lighting.
Again, the video highlight’s Profoto’s high end AirTTL system using B2 and B1 lights but the same high speed sync can be achieved with smaller and more affordable speedlights from the likes of Canon and Nikon, or even cheaper third-party speedlights.
This short video from Profoto shows how shooting with high-speed sync flashes in daylight can help bring back details in the sky. The advantage of high-speed sync is that you can shoot at much higher shutter speeds than the x-sync rating of your camera. Most systems allow you to go up to 1/8000s, which means you can bring ambient light down without needing a ton of light from your flash.
In this case, they used a single B2 head in a softbox to balance the flash and ambient light. While the Profoto kits can be very expensive, the same effect can be achieved using smaller and more affordable speedlights. If name brand speedlight kits are still too expensive, third-party speedlights are available with the high-speed sync feature for less than $100.
