Tutorial: How to use the guide number of your flash
GN = distance * f-stop
Your flash's Guide Number (GN) is determined at 100 ISO, when it gives correct exposure at a certain distance, multiplied by the f-stop
The idea that we can figure out the manual flash exposure by the combination of distance and aperture (for a given ISO setting), was covered in these recent topics:
- getting the most power out of your flash / speedlite / speedlight
- practical tutorial: controls for manual flash exposure
In these articles, we relied on the display on the back of the Read more inside...
Getting the most power from your flash / speedlite / speedlight
This might be obvious, but the most power (or light) that you're going to get from your flash, is at full output in manual. Then the flash dumps everything it has. Full power. You could of course zoom your flash-head a little tighter and get more power / range, but essentially, you're at the limit.
This is useful to know when you're balancing flash with bright sunlight. With this portrait of Shawna, out on the Las Vegas strip, I wanted that sun-flare look ... but I also wanted to balance the super-bright background Read more inside...
WPPI 2012 took place during the past week - as always, a crazy-hectic and exciting event. I once again presented a Master Class at WPPI. But I also took time to present a private mini-workshop to the first 3 people that signed up. We went over a condensed version of my full-day workshop, covering most of the material in the 4-hr long mini-workshop. Like last year, I called on my favorite model in Las Vegas, Shawna. Actually, she has since moved to L.A. but she was quite happy to make the trip back to Las Vegas to be our model.

photo sessions - Shawna - using a variety of photographic lighting options
Shawna is the delightful model I used while I was in Las Vegas a few weeks ago. She helped us out during the mini-workshops I offered, as well as some photos of my own. I've posted a few photos from these already, but thought it might be interesting to show a further selection of images and discuss them ... Read more inside...
photo session - Shawna - using the PocketWizard AC3 Zone Controller
While in Las Vegas for WPPI 2011, the team at PocketWizard asked me if I would be interested in them shooting a short video clip of me using the new PocketWizards for Nikon. I didn't hesitate in saying yes! Here is the description of the setup of the one photo sessions I did. There was another one, which I will post in a day or so. I will post a link to the PocketWizard video clip as soon as it is up.
For this demonstration of the PocketWizard FlexTT5 and AC3 ZoneController, I relied on Shawna, a favorite model, Read more inside...
It's easy enough getting nice clean open light with a single on-camera speedlight when shooting indoors. By bouncing your flash with the idea of getting directional light from your flash, you can effortlessly get portraits like this. As usual, I used the black foamie thing to flag my flash and get more light on the one side of my subject's face. In this case, more subtly so than some other examples on this site.
We were working in the same location here as shown in the previous article where I photographed Shawna using only the available light that was Read more inside...
Photography: Direction of the light - using available light
This striking photo of Shawna illustrates something that I want to underline: at some level, our consideration of the light that we're using remains the same, whether we're using available light, or flash, or video light or some other continuous light source.
We need to consider the direction and quality of the light we have or are creating. We then either need to adapt our lighting, or adapt our way of shooting our subject, to complement our subject. So let's look closer at the light / lighting used for this photo ... Read more inside...
