I have been following your videos and you put out some stunning photos. About this video though and it's something a lot of photographers leave out when using speedlites is the zoom. For your background or rim lights they were set to 1/2 power but what did you set their zoom to? Were they at their widest (24mm) or 70mm or 115mm or somewhere in between?

@H75119847 And so would i ;) Higspeed flash and ND filters are my friends.

@Niobifyed by the way in a situation like that i would choose the sweet spot of my lens, perfect focus, low iso and all that stuff

@H75119847 Even when a camera system is near or just past its diffraction limit, other factors such as focus accuracy, motion blur and imperfect lenses are likely to be more significant. Softening due to diffraction only becomes a limiting factor for total sharpness when using a sturdy tripod, mirror lock-up and a very high quality lens. Diffraction is just something to be aware of when choosing your exposure settings, similar to other trade-offs such as noise (ISO) vs shutter speed.

@Niobifyed with a high megapixel body you will see diffraction, for example, at 70mm, f/11 will cause diffraction, if you have a wide angle lens, like a 16mm, you will see it at around f/18. That's why the Canon 400mm f/2.8 reaches its maximum sharpness at around f/5, while the 16-35, at 16mm reaches it at f/16. Of course if you use a crop body diffraction will appear at f/5 on a 400mm, and at f/11 on a 16mm. It all depends on the size of the pixels in your sensor and the focal lenght you use.

@H75119847 Diffrraction starts at F22. Not all lenses gives diffraction at F22. Some lenses you can go upp to F32 whitout noticable diffraction.

hey Joel, this is so informative. I practically live on youtube, but I'm a little sad that I'm only just finding your channel now. I'm glad I found it though. Did you attach the strobe on the boom arm the same way you did your back lights? I mean did you use your special rig?

Very good!

octagon softbox in "Grid" or "softbox"?

Is that the old slaughter house in Tucson?
I'm a bit confused about your exposure and why you need f18. You used the f16 rule which is in the run - but then you shot in the shade which is likely 2 or more stops darker. So f16 with 100 ISO would be at 1/25th.
Then you said your cameras shutter syncs at 1/200th so you could actually shoot at f5.6. No?
what am I missing here?

The sunny 16 rule only applies when it is full sun light and the sun if fairly high in the horizon. However, the sunny 16 rule is a starting point and you could set your camera to f/22 at 60th or f/11 at 250th. As the light changes so does your camera setting, and normally I start changing my shutter speeds to longer exposures as the light gets darker.
