Conference Call Hold Music

At my job, I practically live on conference calls. 99% of the users of the application I support are not in the building where I’m located. Heck, half the servers aren’t even in my building. As a result many of my days are spent in conference calls. It isn’t uncommon to be on a conference call when someone puts the call on hold, and those of us still on the call are subjected to hold music until they return. This is easily avoided by pressing *6 to mute your line, but conference call noobs don’t always know this.

After listening to music on a call today, my friend Kevin wondered how many people would be required on a call before the likelihood of getting hold music exceeded 70%. I quickly put together this formula:

Np * Pn * Ph = Pm

Np is the number of people on the call.

Pn is the probability of noobs being on the call

Ph is the probability that an average person will need to put the call on hold

Pm is the probability of hearing hold music on the call.

I estimated the probability of Noobs (Pn) as 20%, and the probability of needing to put a call on hold at 10%.

Np * 0.20 * 0.10 = 0.70

Solving for Np,

Np = 0.70 / (0.20 * 0.10) = 35

So, at around 35 people on a call, it becomes very likely that someone will subject the conference call to hold music.

Kevin disagrees with my Ph and thinks that should be 20%, which means at only 18 callers, we’re at a high likelihood of being irritated by hold music. He’s going to start tracking data so see which of us is right.

Mescalito Funk Rehearsal Shoot

Mescalito Funk had a rehearsal tonight, and I invited myself along to shoot the band. Here are the best of the shots, with the mascot thrown in to balance the result.

My favorite is the upper left of the saxophone player with the trumpet player in the background. The light in that one is just awesome, methinks.

Artist-Photographer Robert Bergman

On the drive home last night, I heard a story on NPR about Artist-Photographer Robert Bergman. He’s known for his portrait photography and it seems the only samples on the web are those that are available on the NPR site. Those 13 portraits are interesting and fascinating, but certainly a very narrow view of his work. He has one book, and I’ve put it on reserve at the library.

What struck me most during the interview (you’ll have to listen to it–the web page isn’t a transcript) was his inability to describe his artwork in a way that is accessible to the rarefied, erudite listeners of NPR. Even the interviewer and producer were flummoxed by his rambling, obtuse, impenetrable description of his artwork. The weirdness starts at 1:15 “it wasn’t exploring the putative differentiators…chained to the academic deconstructivist theory…new modus operandi and conceptualism … reacting to the cumulative effect of sequencing…” But then he’s able to “dumb it down” a bit later, at 2:50: “I would say that anytime we meet a person it is impossible for us to not somehow figure out what they’re about. We start doing that instinctively. Remember, I’m dumbing this down because you asked me to dumb it down.”

So, his artwork is about getting us to strip away our assumptions about a person by removing most of the context which would normally help us assess that person. His artwork, for us dummies, is about getting us to leave behind our prejudices. That is worthy artwork indeed. Its unfortunate that he has such difficulty making it accessible to the masses.

As a budding photographer, I’m fully aware that photography is part technology, part artwork. I’ve been spending a lot of time figuring out the technology, while attempting to develop my own sense of what I want to capture artistically. I certainly have a long way to go in both. When I heard his first description of his artwork, my first thought was “wow, I really don’t want to become someone like that”. I want to be able to describe my vision or purpose and have people immediately get it.

Shooting a band in a pub

This past weekend, I was invited to be the band photographer for a band we’ve been following for a couple of years, Mother Grove. The request came from Brad, the lead singer:

I really like where you’re going with alot of your photography. You think you might wanna take some good shots of the band when we’re in town.

That original request applied to a different date and venue, but when they added a show in Dayton I figured I could use the practice.
The venue in question is the Dublin Pub. We’ve been there before, and I remembered it was quite dark. I would definitely need to use flash, even with a better camera than in previous visits.

In preparation for the event, I made three additions to my camera gear.

  1. I knew that my previous diffuser project would throw light everywhere, probably irritating the patrons more than lighting the stage. So I started looking for a design that would push the light forward. I made a bounce flash diffuser very similar to this one.
  2. I purchased some flash gels with two goals in mind: a) white balance color correction, and b) artistic effect. As it turns out, I didn’t feel like taking the time to switch the gels around, so I just stuck with the color correction. More on that below.
  3. I made a hand-strap, similar to this one. I’ve recently found a neck strap to get in the way, and have either left it dangling while I’m holding the camera, or tried to wrap it around my right hand. Replacing it with a hand-strap seemed like an ideal solution.

So I loaded up the camera bag with a bunch of batteries, both lenses, both flashes, wireless flash trigger, and 12GB of SD cards, and a freshly charged camera battery.

When I got there, I realized that I had forgotten just how dark the pub was: dark paneling and very dark ceiling. And the stage lights were 5 gelled flood lights directly over the stage. And they were five different colors. There were no lights (except my flash) hitting the performers in the face. The floods just hit their hair. Oh, and did I mention that those overhead floods were like 45 watts?

Four hundred plus shots (as in photography, not liquor) later, I learned a great deal. The huge majority of the night I shot on manual shutter and aperture, autofocus, and a single manual flash off-camera. I shot the majority of the time with my kit 18-55mm lens, though I did switch to the 70-300 for a while to see what opportunities that would present.

New stuff that worked well

The flash diffuser was fabulous. Even on-camera, it produced a wonderfully even, soft light. Snap-shots in a bar never looked this good.

Any time the flash was on the camera (or in my left hand) I had the diffuser on. Oh, and notice the distinct lack of red-eye? None. Not in any of the 400+ shots, even at long distances from the subjects. That alone saved hours in post-processing.

At the beginning of the night, I put a full CTO gel on the flash. This adjusts the white balance of the flash from daylight to tungsten. I also set the camera to tungsten white balance. It looks to me like the flash and the ambient (what little there was) mixed well. Brad’s white shirt actually looks white. However, I never did change that gel like I had hoped. I had thought about changing to a dark red gel for effect, but since the gel was still in the camera bag in a pack with 53 other gels, I didn’t feel like messing with it. Next time I’ll pull out the two or three that I expect to use into a business card case (or something like that) for easy access.

The hand strap worked very well, and felt quite secure. The neck strap would have been dangling in my way, getting wrapped up in the flash or diffuser, or something like that. However, when I’ve changed lenses in the past, I’ve put the neck strap around my neck to hold the camera while my hands mess with lenses. This presented a bit of a challenge that made me a little nervous changing lenses in a dark, crowded environment. Fortunately, nothing bad happened this time.

I also shot in RAW mode for the first time, other than one or two shot experiments. I had read many comments from experienced photographers that this was the only way to go for two reasons: a) exposure compensation, and b) white balance. I knew that this environment would be challenging for exactly those two reasons. I’ve now seen the light (so to speak) in my post processing and will will hopefully write a full entry about just how that works.

Shooting with the flash off-camera was incredibly powerful in this environment. Since this is a stage performance, it is OK for the light to be “hard” so whenever the flash was distant from the camera (via Cactus wireless triggers), it was either bare or snooted.

This hard light ends up looking a lot like a stage spot light. I also had my absolutely wonderful voice-activated carbon-based light stand (my wife!) who was able to point the flash at whichever performer I wanted. We even played with back lighting some of the performers and the fans. A couple of these shots worked OK, but an additional very low power flash on the front would have helped.

The combination of remote flash, snooted, and voice-activated stand helped me make the best shot of the night.

When I saw this picture on the back of the camera, I suddenly, enthusiastically understood the term chimping: I let out a little “ooh! Ooh!” when I saw it.

Stuff that could have been better
Most of my shots were made at 1/10 second, ISO800, with the biggest aperture possible, and flash at 1/8 to 1/2 power, triggering at the end of the shutter opening. I chose such a slow shutter speed to allow motion blur. It worked well for only two shots (here’s one). The rest of the shots where there was enough ambient light to see motion blur just looked bad. A faster shutter (all the way up to 1/200) would have limited only the ambient light, not the light from the flash. In most cases this would have completely eliminated the backgrounds, which would have been good in most situations. I might have had to boost the flash power a bit to compensate, but that wouldn’t have been a horrible result.

Oh, and by the way, we had a great time. The performers were generally good sports about having me in their faces. Fortunately they’re used to playing pubs where the fans are less-than-polite-body-space away. It was a great experience that I hope to capitalize on soon.

Brad, the lead singer, upon seeing the pictures on Flickr wrote:

No one has ever taken such great pix of us @ the pub. The lighting and clarity is perfect!

Since this band has been together for 10 years with tons of people taking their pictures, I’m very flattered.
