Staying Alert When Shooting
I like to shoot frames in triplets for HDR purposes. It actually achieves two purposes. The first frame is perfectly exposed. The second is 2/3 of a stop over, and the third is 4/3 of a stop over. This gives me the ability to bring up the dark & shadowy spots. Then after I apply the HDR process, I can always play with the exposure rate to get the mood I am looking for, without losing the details.
The challenge To shooting triplets at night is that you have to remember to be situationally-aware ! I was so concerned with getting the exposure correct, I failed to notice the traffic. The first exposure was about 4 seconds, the second about 6, and during the final 9 second exposure a pickup truck came racing through my shot !

Project365 - Of Grids and Snoots
Why would you want to do that ? It allows the photographer to more selectively light the scene. Imagine a photo of a model in a dark room. Perhaps you want to expose the background to look like a black backdrop. That's easily achieved, but you still need to light up the model, to show off contrast and colour. The grid or snoot will help "aim" the light at the models face, while minimizing the spillover onto the background.
The Setup
These are some more "goofing around" shots. None of my available models were out of bed yet, and I was getting impatient. A very simple setup, with the Honl 1/8 grid attached to the Canon 430 EX II via the Honl speed strap. The whole shebang is mounted on the hotshoe of my Canon 60D, which has my general purpose 24-105mm f/4 L lens attached. I shot handheld for quick & dirty testing.
The Photos
A simple before and after shot. First without the grid, followed by a photo taken with the grid.
Note the even lighting. I used no other light modifier, like a gel, as there was no other ambient light - just the flash at 1/8 power.
For comparison, this photo is shot with the exact same settings, and the grid in place. Note how quickly the light falls off ! The grid directs the flash down a very narrow beam.
Lessons Learned
The use of a grid or snoot allows more creative use of light. It provides an easy way of selectively lighting a small portion of the frame, while quickly allowing the ambient light to light the rest. I see this as very useful for fill-flash and portraiture.

Project365 - Two Strobe Portraits
The Setup
My thought was to set up for a black background, and then light the model from above and to her right. Then, I wanted to place another strobe below and behind her. I was hoping to create a sort of light halo effect. Unfortunately, I didn't get the halo as her hair was as dark as the background. Worse, I had remarkably dark shadows across her face.
I shot the Canon 60D handheld. In the hotshoe was one of the Cactus v5s. I was set for a black background - f/250, ISO 100 and an aperture of 16. One Canon 430EX II was mounted on a Cactus v5 atop a tripod to the kodel's right, while the other was mounted on the trigger and placed on the floor.
The Photos
I am still learning about portraiture. It's not really something I'm very good at, so I was fortunate that my daughter agreed to be my model. It is easy to have a good rapport...
In this first photo, the main light was too powerful. While I had a nice dark background, you couldn't really see any definition between the background and the kodel's hair. And the pose is funny - unnatural, even. It looks like her eyes are pointed in two different directions !
Here, the main light is better, but the secondary is still underpowered. There are very harsh shadows on the models face. Given how pale her skin is, I would've liked to have made her skin tones warmer with a bit of makeup.
This one is better. We see a nice cross-lit effect, haloing her cheek and chin. And there is even a hint of catch-lights in her eyes ! But her dark hair is lost in the black background, still.
This is a little bit tighter a shot. I like the effect of the cross-lighting, and the black background.
Lessons Learned
I still need to figure out how to create the halo effect around the model's hair. I suspect my life would be easier shooting at night, when the room is darker to begin with. I'd also like to try to use a reflector to cross-light the face, which would free up the flash for the halo effect !

Project365 - Black Backdrop
It's truly a simple effect involving the use of flash (or sometimes called strobe) photography. Cameras have a maximum speed with which they can sync with the flash to achieve a nicely lit picture, it's usually around 1/250th of a second. Keeping that portion of the exposure triangle still, we next dial down the ISO (the sensitivity of the CCD) to 100. The only thing left that is adjustable is the aperture. All we do is close that down until a picture taken in the ambient light is completely black. Now, anything lit up by the flash will be nicely lit, while the background remains black.
The Setup
Nothing really complicated the Canon 60D, set at f/16, ISO 100, and a shutter speed of 1/250th of a second. The Cactus v5 was mounted in the hotshoe, so I could use the Canon 430EX II off-camera. I placed it on a basic tripod with the other Cactus v5, so I could move the light & the camera around freely.
The Photos
Believe it or not, this is a photo of Pat's flowers on the dining room table. I was setting the ISO, Aperture and shutter speed to get a black background. Got it !
Whoops ! The flash was spilling onto the background too much, so I elected to put a snoot on the flash, to more tightly focus the beam.
That's better ! Although you will notice the pen & paper on the tabletop still show up faintly. Now to play around a bit... ;-)
The first few pictures weren't as bright as I would have liked, so they came out a little dull. Time to up the power of the flash a notch, and move the light stand a little closer !
Much better ! I like the contrast created by the various petals on the flowers.
I think this is one of my favorite photographs of the shoot...
Lessons Learned
I thought I really understood this technique, but now with a little better tutorial, I think I know how to nail it whenever I need it. Certainly, implementing the snoot helped narrow the beam, and moving the light stand over to one side helped with not lighting the background. I really like this technique & see myself using it for portrait work.
