review: Canon ST-E3-RT Speedlite Transmitter and Canon 600EX-RT Speedlites

In my review of the Canon Speedlite 600EX-RT, I’ve already raved about the ease of use of the new speedlite – thanks to a menu system that you can follow without having to decipher it via a manual), but mostly because of the built-in radio control of the flash. This elevates the Canon 600EX-RT to a new level. As mentioned in my review, I really think this flashgun will change things in the photo industry. It’s huge.

I’ve only now been able to get hold of the ST-E3-RT Speedlite Transmitter (B&H), to use with the Canon 600EX-RT speedlites, and I am just as impressed.

The main advantages of this controller, is that you can change the flashes’ output directly from your camera. No need to run to and fro between your speedlights to change a flash’ output. And of course, The Big Thing about the new flash system, is the built-in radio control. You’re not limited by line-of-sight anymore, or compelled to buy radio slaves. It is obvious that Canon has done their homework on this puppy. While it is a complex flash system, the Canon ST-E3-RT isn’t a complicated device to use.

To test this system, I used three Canon 600EX-RT speedlites (B&H) and a ST-E3-RT Speedlite Transmitter (B&H) in a photo-shoot. As always, there’s a description of how I used this in the photo session … but more interestingly, a behind-the-scenes video clip of how the Canon 600EX-RT speedlites were set up for this photo shoot.

Flash photography is one of those subjects that seem daunting from ‘the outside’.  It might seem like you’re chipping away at something so big that it might even appear incomprehensible. 

I actually do believe that flash photography is one of those subjects where you have to grasp a number of things simultaneously, before anything makes real sense. 

So here is my list of Top 20 Flash Photography Tips

This page has just been added to the main set of pages on flash photography techniques. My intention is that it might serve as a solid starting point in understanding flash photography, with links leading to various other pages within the site.   Hopefully it all converges to the same point – some aha! moments where everything seem a lot clearer.  And hopefully that page will help some in making flash photography more accessible a subject than it might appear.  

As always, your feedback and questions on that page is welcome.
