Controlling bright daylight with direct off-camera flash
Working with Molly K as our model during an personal photography workshop in New York, we put into action the thought-process when using flash in very bright light. There's a specific algorithm that gets us to optimal settings.
But, as usual, there's more to a final image than just the numerical settings on the camera ... Read more inside...
Maximum flash sync speed, and the Nikon SB-900 / SB-910 speedlight
Because of the way the focal plane shutter works in DSLRs, shutter speed doesn't affect our flash exposure ... while we don't go over maximum flash sync speed. When we go into high-speed flash sync, our flash output drops. (The linked article there explains it thoroughly.)
However, when we work with ambient light (and intend to add flash to our subject), then a change in shutter speed has an indirect effect on our flash exposure. A change in shutter speed will mean a change in aperture, and this is what affects our Read more inside...
In my review of the Canon Speedlite 600EX-RT, I raved about the ease of use of the new speedlite by Canon that has built-in radio transmitters. The same with my subsequent review Canon ST-E3-RT Transmitter. This system is going to have huge impact!
The behind-the-scenes video clip as I set every thing up, is of the photo session with Molly K where I used Canon 600EX-RT Speedlite (B&H / Amazon), and the Canon ST-E3 Speedlite Transmitter (B&H / Amazon), during an actual shoot. You can actually hear the Read more inside...
review: Canon ST-E3-RT Speedlite Transmitter and Canon 600EX-RT
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.
The main advantages of the Canon ST-E3 Speedlite Transmitter (B&H / Amazon), is that you Read more inside...
Off-camera flash in low light - choosing your shutter speed
With flash photography, the maximum flash sync speed is an important camera setting. It is the best go-to camera setting when you use flash in bright ambient light. But when we shoot in low ambient light levels, then we need to adjust our shutter speed accordingly. We would most likely be at a shutter speed where the ambient light shows up. We want some of the ambient light to register in our photographs, because it gives us context. Allowing more ambient light to appear in our low-light photos where we use flash, enhances Read more inside...
My favorite diffuser / modifier for off-camera flash, is the Lastolite Ezybox 24x24 for speed lights (affiliate). The Lastolite Ezybox has featured often on the Tangents blog. (Here is the review). It's easy to use and super-easy to set up. And in its original configuration, folds up to a surprisingly small bundle.
The good news for photographers who have been curious about the Lastolite Ezybox, is that Impact now makes a softbox - the Impact Quikbox 24x24 softbox (affiliate), which is virtually identical, at a lower Read more inside...
