Chocolate Coated Potato Chips with a side of Strobist

David — Tue, 13 Oct 2009 05:58:30 +0000

I really haven’t photographed food before–not in any serious fashion–so when I found myself confronted with a silver platter of chocolate-covered potato chips yesterday at the Candy Factory in Columbia, Mo., I was thrown for a loop.

There was no chance I would use existing light: it was a mix of daylight and tungsten, and exposing for the chips coated in which chocolate would have meant underexposing the others significantly. So I set up two lights bouncing into umbrellas at either end of the silver tray. It took me a while for all that I learned about photographing metal–and look how little of it wound up in the final frame!–and its family of angles to come back to me (about 50 chimped frames) but once the reflections were under control, it just became a matter of the ratio between the key and the fill lights.

Ultimately, the SB-80-DX, on camera left, was fired at a third stop under 1/2 power, and the 550EX on camera right was fired at 1/16 power. Could I have balanced those a bit? Probably. The shadows cast by the milk chocolate potato chips bother me a bit. I’ll file that in the “next time” category.

Multiple-flash IS for the Birds

David — Mon, 25 May 2009 08:22:44 +0000

I’ve been battling a cold ever since grad school got out for summer–a great way to celebrate the end of the year, but at least it didn’t strike during the week before when projects were due!–but yesterday, for the first time since getting home, I felt like making some images. The bird activity at home has been really great, although I picked a slow day to photograph (less likely to disturb the migrating species, though!). The suet feeder has been getting a lot of activity from our resident, nesting pair of Red-bellied Woodpeckers and our Downy Woodpecker, but it was really the nuthatch that let me get a good look at him.

Three flash units were set up on stands, combined with the late-afternoon sun, made for a four-light setup, albeit back-lit. I was trying to get some rim-lighting, and between the sun and another strobe back and to the right, I figured I would get quite a bit. I certainly got some, but not quite what I wanted. My key light was backed up quite a bit, and I had a fill on the left, which is casting the nuthatch’s shadow that you can see on the suet feeder.

More after the jump…

For a first attempt at multiple flash for bird photography, I think the result is OK: the moment is good, but the lighting could still be better. Working a back-lit situation is hard to begin with, but it’s didn’t seem feasible to photograph this feeder with the sun to my back, because the background would have sucked. Also, there are only so many “bird on a feeder” photographs that one can bear to create….having some (for stock) makes sense, but I need to be more patient and wait for them to land on the perches Dad has set up near the feeders.

I’ll definitely be trying this some more throughout the week I’m home.

One thing that did amuse me was this Black-capped Chickadee who thought that one of my strobes made for a good perch:

Ghosts on a Bridge – Painting with Light

David — Mon, 27 Apr 2009 06:26:38 +0000

Romantic ghosts of prom past on the MKT Trail, Columbia, Mo.

For a group project for Advanced Techniques, Vivian Esparza, Charles Ludeke, Lesley Freeman, and I met up at the Martin Luther King, Jr. memorial along the MKT Trail in Columbia, Mo. to make a long time exposure with added light–also called “painting with light” for its surreal effect.

Charles friend, Michelle, agreed to be a model for us on the bridge. After thinking on it for a bit, we decided that we should include a male figure in the photo, and Charles volunteered that he had a yellow tux (rental) in his car from a social gathering a on Friday night.

The background trees were lit with a Nikon SB-900 gelled green. I fired it off at 1/4 power for the nearer trees, and worked my way up to 1:1 for the background trees (knowing that they would be far too dark otherwise). Vivian did a great job of painting the bridge blue (an SB-900 with a blue gel), and Lesley walked along the bridge once with a flashlight aimed downward (on the ground, along the railing). Lesley then used a different flashlight, gelled red, to paint the post and upper railing of the bridge.

Finally, Charles and Michelle would pose on the bridge, and I used my Canon 550EX with the Panera straw-grid, dialed at 1/2 power, to “freeze” our ghosts in the frame.

All told, the exposure came to 5.7 minutes @ f/8, ISO 200 using a Canon 5D Mark II and 70-200mm f/4 IS lens @ 81mm…and a couple hours of experimentation. It was a great collaboration….and I think we might go back in a week to do something a little bit different ( but not in time for class).

Working with 2nd Curtain Sync

David — Thu, 23 Apr 2009 07:22:57 +0000

Everyone in Advanced Techniques was asked to create a photojournalistic image using second curtain (or “rear curtain”) snyc with their strobes. I actually haven’t used the technique much in the past, largely because it’s inordinately difficult to do so with the Canon flash system. Comparatively, the Nikon system of switching the flash mode from “normal,” skipping over “red eye reduction,” and landing on “rear” is all that has to be done. It’s stupid simple. More stupid for Canon…..c’est la vie. (But cameras that start with the letter “N” do seem to have strange white balance………)

Click on the diagram for a larger version.

For the simple reason that second curtain sync is easy to achieve with Nikon, I borrowed a D700 and an SB-900 from the photo department. I only took out the 24-70mm, knowing that 90% of what I had planned could be done with that one lens. First, I went to the Hulett House mixed martial-arts gym, the subject of a longer-term group project, to practice with the technique. I set up one light on a stand, gelled CTO, and bounced if off of the ceiling.

After only a few frames, I captured this image, which is one of my favorites from the evening:

Kevin Croom tries to place Kristin Rambo into a headlock during a sparring match at the Hulett House Gym on April 22, 2009, in Columbia, Mo. Croom, who is yet undefeated in his mixed-martial arts career, is helping to get Rambo ready for her first Midwest Fight League contest on May 25.

Two more images after the jump…
After the Hulett House fighters wrapped up practice for the night, I called up Calin Ilea, one of my partners in crime at the j-school, to see what he was up to. He suggested I could drive up to the rooftop of the Hitt Street parking garage as he was shooting bicycle polo with some of our other colleague from class.

Eventually, I set up two lights (both gelled CTO to try to play along with the sodium vapor on the rooftop). I triggered my Canon 550EX with an eBay “poverty wizard,” and set the SB-900 to “SU-4″ mode, which makes it act like an optical slave.

This way, even when I lent Calin the radio trigger for the 550EX and he gave me his SB-800, I could still trigger two flashes at once thanks to the optically-slaved SB-900.

OK, enough geeking-out. Here are my best images from bike polo:

An evening spent painting with light

David — Wed, 22 Apr 2009 06:11:15 +0000

Just an outtake from a class experiment with light painting at Rock Bridge State Park in Columbia, Mo. This was likely the most successful image of the evening. There’s also an assignment to pursue this line of work in smaller groups, so look for something different in the coming days.

Multiple Flash for Action Events

David — Tue, 21 Apr 2009 06:55:55 +0000

Recently I’ve been trying to make photographs of the fighters at the Hulett House, a mixed martial arts training gym run by Rob Hulett and part of the Midwest Fight League, while sparring with each other using at least two flash heads for cross lighting. One of the greatest challenges is to ensure that the light stand (I’m triggering wirelessly either with Canon ST-E2 transmitters of with eBay “poverty wizards”).

In this case, I’ve lit the scene with two 550EX Speedlites aimed right at one another. I was using daylight white balance because I was letting the flash heads overpower the ambient light, but now I regret that decision and wish I had gone with a CTO gel and tungsten white balance to make the overhead lights appear white. C’est la vie.

Also, the shadow cast by the strobe on the right is a bit distracting. But what made this, to my mind, the strongest of the images was Croom’s expression paired with the position of the bright red boxing glove in the lower right-hand corner.

Without that glove as an anchor for the composition, this wouldn’t be a successful image at all.

Kevin Croom (right) takes a swing at Eric Ward during an evening practice at the Hulett House Gym in Columbia, Mo. on April 7, 2009, three days before their Midwest Fight League contests at the Blue Note. Croom said that in a week before a big event, he just wants to hit people.

More photos after the jump.

The same lighting setup for a photo of Croom and Glen Baum.

I enjoyed the shadows cast by the two lights in this image. However, I had to brighten it a bit as the fighters were farther from my key light than I expected so I was about 1/2 stop underexposed.

Finally, this image employed two strobes in cross light, but bounced off a wall and ceiling, respectively, with a third strobe acting as fill.

Some inspiration in slideshow format

David — Thu, 09 Apr 2009 07:18:54 +0000

I was watching some audio slideshows for a class assignment and found a few that might be of interest to viewers of this site.

Martin Schoeller and Steve Pyke are staff photographers for The New Yorker and have an interesting discussion about some of their portraits that are being exhibited at the National Portrait Gallery in Washington, D.C. through this fall: http://www.newyorker.com/online/multimedia/2009/01/12/090112_audioslideshow_portraiturenow.

I recognized some of Schoeller’s portraits from a different slideshow that was originally published on Media Storm. He certainly has a distinct style. Makes me want to go and make some strip lights………

Flash for Balancing and Fill

David — Thu, 09 Apr 2009 06:46:59 +0000

Ryan McCullen of Hubert Builders boards up the window frames of 22 9th Street in Columbia, Mo. The space, which was previously the headquarters of the local Obama for America campaign, is now being renovated for a planned women's boutique.

“Fill flash.” It’s a term familiar to pretty much everyone. The only thing that makes it more interesting is when you decide to take the flash off of the camera and place it on a stand. This frees up the photographer to place the light where it should be, not where the camera is positioned. For wildlife photographed with a 500mm lens, placing the flash on axis makes a lot of sense–on a cloudy day just dial down the flash to -2 or -3 EV (via ETTL), put a Better Beamer on there, and call it a day.

For this assignment I was working with less space than I would have liked, and what began as a completely open storefront was actually being boarded up by the construction worker, Ryan McCullen. I really wanted a second light: one inside (behind him) to work in tandem with the flash that I had with me. Of course, before he boarded up the windows, I had two lights (the sun, hopefully operating at full power…).

I triggered the flash on the light stand with some “Poverty Wizards”–the cheap radio remotes from Hong Kong that are all over eBay. I do own a Canon remote trigger, but it is based on infrared line-of-sight, and in bright sun it simply doesn’t work. If I could afford Pocket Wizards…some day. Until then, the cheap eBay remotes seem to be working!

With a little help from the fill light slider in Lightroom, the image opens up pretty nicely, and the juxtaposition between McCullen working away and the motley crew of people hanging out on the street–”We’re All Vampires” does amuse me.

More after the jump…

Here’s a basic breakdown of my lighting setup, as well as the original (untoned) image:
