Tech Tip: One Way To Check If Your Remote Control's Battery Is Dead

This is an old favorite of mine.

So, let's say that you've got a remote control - and I'm talking specifically about remote controls that utilize infrared (IR) technology, not raido frequencies (RF) - and you need to see if the batteries are working or not. Normally, you'd just point the remote at whatever it is that it controls, and test it out, right? If it works, the batteries are good, if not, they need to be replaced.

But what if you don't have access to the thing that it controls? You've only got the remote. And you need to make sure it works. Sure, you could just put fresh batteries in just to be sure, but where's the fun in that?

Here's what I do when I'm in that situation:

If I'm at my computer, I fire up PhotoBooth or iChat, or any other app that will turn on the built-in video camera and bring the picture onscreen. If I'm out and about, I'll just use my iPhone's camera app.

Next, I simply aim the remote control right at the camera and press a button or two.

If it's working, I'll see a white-ish/purple-ish light blinking from behind the IR cover on the remote. If it's not, I won't see anything.

Pretty neat, eh?

This has come in quite handy a number of times, especially when troublshooting.

You can also use this trick to see other IR lights, like the ones used on small closed-circuit security cameras.

 

Have fun!

Ejecting disks from the Finder

As some of you may know, I've been a pretty hard core keyboard command guy for a pretty long time.

I just discovered a pretty handy trick that I thought I'd share.

I have a few external hard drives that have multiple partitions on them. It's not unusual for me to only want one or two of those partitions mounted at any given time, and the fastest way to unmount a partition is to selcet it in the Finder and hit command-E (for "Eject").

In the past, doing this would bring up a dialog asking you if you a) wanted to eject just that partition, b) wanted to eject all of the partitions, or c) wanted to cancel. You'd have to click one of the buttons, and off it would go.

Today, I was monkeying around in Lion, and found that if you select a partition on a multi-partitioned disk in the Finder and hit command-option-E, it would eject all of the partitions without the pesky dialog.

Additionally, I found that control-command-E would eject just the partition you had selected (again, no dialog).

I confirmed my suspicions, and found that these options actually do appear in the Finder's File menu when you pop the menu open and then hold down either the option and/or control keys (this is a handy way to discover other neat hiding keyboard commands).

Then as a lark, I decided to check out the Finder on my machine running Mac OS X 10.6.8. And how bout that - it's in there, too! I'm not sure if that's been in there since 10.6.0, but I'm pretty darn sure it wasn't there in 10.5, when that dialog was originally introduced (I don't have a 10.5 machine handy to confirm).

Anyway.

Share and enjoy.

Happy ejecting!

Hand Trucks. (or, how I manage to travel in the city with all of my stuff - without a car)

When I moved to New York City from Chicago in April of 2006, I did so with my trusty Subaru Impreza mini-wagon. I loved that car. It was small enough to fit into tight spots, but big enough on the inside to hold a ton of stuff.

By August (a mere 4 months later), I had realized that it was financially unfeasible for me to own a car. I had already gotten two or three parking tickets, my insurance premium had nearly doubled (from what I was paying in Chicago), and I was still paying off the car. It was something like $500 a month, all together. And given that the majority of the driving I was doing was just moving the car from one side of the street to the other a couple of times a week, it just didn't make any sense.

A couple of craigslist posts and a week or two later, and I was able to sell the car, essentially handing over the payments to the new owner. Nice and simple.

Of course, that put me into a new category - someone who has a lot of stuff, but doesn't have a the means to move it around. At the time, it made a lot of sense: I wasn't playing the drums actively (all of that stuff was actually in a storage unit, anyway), and I was working at Apple on the night shift, full time. So it's not like I had a ton of stuff to carry around.

But as I settled into becoming a New Yorker, I started to get back into playing music, and it wasn't too much longer before I decided that I wanted to become a professional photographer. And you know what that means, right? Of course. All professionals must have tons and tons of gear. It's a simple matter of fact. So how the hell was I supposed to carry around my drums and/or camera and lighting gear around? Big backpacks were a definite help, but what if I needed MORE? You guessed it: hand trucks.

I've had a folding hand truck of some sort for quite some time; I actually kept it in the trunk of my car back in the day. The first one I got was one of these: a Ruxxac fold flat cart, with an extended toe plate (that's what they call the bottom part of the cart, where your stuff sits). This cart is great. It's light weight (only a few pounds), and it really does fold down to be like, 2" thick. I actually still have it, and use it from time to time, depending on the situation.

The downsides to this old guy are that it's starting to get a little "loose" in its old age (it's over 10 years old, at this point, so I don't think it really owes me anything), and it takes about 15 seconds to set up. I know, that sounds ridiculous, but believe it or not, the modern day incarnation of this design has been vastly improved, and can be set up in like, 5 seconds. And when you're standing out in the rain at 3am, trying to break down your cart so you can get it into the back of a cab, every second counts. More on that later.

Once I started getting busier with playing the drums here in NYC, I found myself needing to solve the problem of getting my stuff around with the least amount of effort and expense possible. Sure, I could use a Zipcar or take a taxi, but those options are a bit pricey and sometimes just impractical. Catching a cab in Bushwick was next to impossible, anyway.

So the Ruxxac is a great cart for hauling around a bass drum case (ranging in size from about 18x18x18 up to 26x20x20 or so), along with another bag sitting on top of it. It could also handle a nice stack of small photo cases, like the Lightware MultiFormat case I use for my lights, the Pelican case for my camera, and a couple of older Domke satchels, filled with other odds and ends. I'll generally bungee a stand bag to the back, as well.

Sometimes, however, the Ruxxac is a little too much of a cart for the job. It's a little bulky to carry around folded up (I'm too short to just hold it by its handle; it hits the ground as I walk), and again, it's slower to set up and break down. So I was shopping around one day and came across this little guy: the Magna Cart. It looks bigger than it really is in the pictures. This cart is essentially the same as the Ruxxac, but it's about 20% smaller. It also has some nice features that let you set it up and break it down with just one hand (and a foot) in like, 5 seconds.

This cart is great for smaller, more compact loads. Like, a stack of 2 or 3 photo cases, or just one big fat stand bag, bungeed to the handle. It can't handle much more than 100 pounds, though, so you can't get too crazy with it.

There's only one shortcoming that I can speak of with this cart: the handle is a bit too fragile. The handle is made of (I'm guessing) aluminum squared tubing, and the design is such that the top section telescopes into the bottom section. Just like the built-in pull handles found on most wheeled luggage these days. There's a nifty lock/release bar just under the main grip at the top of the handle, which is usable with a single hand (just pull up on it, and you can adjust the length of the handle; easy).

So let's say you're walking down the street with your Magna Cart, and everything is swell. You're pulling it behind you, and uh-oh - the cart gets stuck on a bump or a large crack in the sidewalk. You weren't pulling that aggressively, and the cart slips out of your hand. Because of the angle that you were pulling it behind you, the cart doesn't land back on its base plate (or toe plate), it instead tips forward, and ends up landing on the handle. Depending on the load and how you've got it secured, this can put too much stress on the thin aluminum tubes that make up the handle - causing them to bend. I've dropped mine in this fashion maybe 3 times, and I can tell that it's only got maybe one or two more drops left in it before the handle gets bent enough to become unable to properly extend and retract. Fortunately, I've been able to muscle it back into a usable shape, but again, it's not really constructed that strongly, and I think it's days are numbered.

That all said, I think it's a fine cart. Especially for the price; I think I spend about $35 on mine. My Ruxxac cart cost closer to $100, I think. But I bought it from Calumet Photo in Chicago, and they aren't exactly known for the their rock-bottom pricing.

The next cart I got was my favorite. I say "was" because, unfortunately, I managed to misplace it while moving this winter. I picked up a Wesco Maxi Mover from Adorama, and it was great. It had the speed and convenience of the Magna Cart, plus the capacity and larger toe plate of the Ruxxac. I've decided to wait until the Ruxxac completely dies on me to replace it, however.

Why? Because I'm crazy, and I figured if I was gonna spend money on yet another hand truck, I should get something that could hold even more stuff, and be easier to move around. I'm sure you've all seen the kind of cart I'm talking about. I used to see photocopier repair guys with these things all the time. They're made of steel, and have this nifty little feature - a second set of smaller wheels with a little "kickstand" that supports the cart at the optimum 45ยบ angle you'd hold it at when pushing or pulling it.

I did some more shopping and research, and decided that this one would be the best compromise as far as cost, size, and capacity were concerned: The Clipper 880. A bit more expensive, yes. But - this thing can hold a TON of stuff, and it feels really solid. And man, that little rear wheel thingie kicks ass. It's really nice to be able to just let the cart sit there, ready to roll, without having to "knock it over" into position any time I get moving again after coming to a stop. Which, given my current living situation (in a neighborhood where there are lots of trains nearby, but they're all a good 5-10 minute walk away) happens a lot.

I've only had the Clipper for a few weeks, so I can't really speak to its durability just yet, but so far, it's been a real champ. Another nice feature is that when you flip the helper wheels back up, they let you use a pair of metal rails that make sliding the cart up or down stairs relatively painless (down is obviously way easier than up).

My only knock on the design is that the helper wheels don't seem to lock into place when they're not being used. I might keep a small bungee cord on hand to keep it secured for situations where I won't need it (or if I've got a lot of stairs to deal with).

So that's my take on hand trucks. Gotta love 'em!

Studio on my back

This past weekend, I was asked by my friend John to come by his apartment to work on some photos of him and his roommate, Suzanne. They live in an older apartment building on the outskirts of Williamsburg and Bushwick, and Suzanne has decorated their place with all sorts of neat-looking vintage furniture and nick-nacks.

The two of them - John, being a rather fashionable fellow and former stylist, and Suzanne, being an actress - had a surprisingly wide variety of cool vintage clothing that they wanted to get dressed up in. We figured it might be fun to go for that classic "old time photo" look.

Mind you, we hadn't discussed this beforehand - all I knew going in was that we would be shooting in the apartment, and there might be a cat.

So I decided to try to over-prepare myself, and set to put together a rig that would allow me the option to use up to five lights, with an array of modifiers to go with them.


I looked at the directions to get to their place from my place, and unfortunately, there was no direct route. The nearest train stop is a good 15 minute walk, and there isn't a bus that goes near there, either. I didn't want to deal with calling a car or trying to find a taxi, because dammit - I've got a bike.


Normally, I'd pack two bags - my Pelican 1514 hard case, which would carry all of my camera gear and the strobes, and then my trusty Kelty backpack, which would get stuffed with all of the grip equipment. I've travelled this way many times in the past, and when I'm only walking a few blocks here and there (to and from the train), it's no problem.

This time, however, I figured I'd test my limits a bit.

As I was unpacking my gear from the Pelican case, I was struck with an idea - "I wonder if this padded divider insert would fit inside my backpack..." Sure enough, it fit inside perfectly. With room to spare, in fact. With the dividers in my pack, I was able to load up just about everything I'd normally put into the Pelican case. Since there was still room on top, and I needed some tension to ensure that everything held in place, I started placing my various modifiers and grip gear on top of and around the insert, until the bag was nice and tight. It zipped up without a problem.

Finally, I grabbed a pair of flimsy - er light-weight - light stand bags, and managed to stuff the remaining gear into them, and then secured them to the sides of the backpack. I picked up the pack (which must've weighed a good 40+ pounds), and it felt well-balanced. Sure enough, once it was on my back, it felt great. Looking in the mirror, I kinda felt like a little kid who was pretending to be Boba Fett or something (I know, I know, he didn't have two things pointing out of the sides; he had the one thing pointing out the middle. I said "little kid", okay? sheesh.)

With the pack secured, I hopped on my bike, and proceeded to shoot the following pictures:

I was so impressed with my pack-job, that I decided to make a little video of myself unpacking it all:

Light Reinforcement

As some of you might know, photographing musicians performing on stage at a typical venue can be a bit of a challenge.
Most of the time, the lights that are there are either not terribly bright and/or poorly positioned. Most clubs don't really put any energy or effort into actually lighting the stage, and I can't say that I blame them - it's extra work for someone who's probably not getting paid much (if at all), and since each set is only going to be 30-60 minutes, what's the point?

I've been experimenting a bit with shooting shows a bit lately, and decided to share some of my experiences and ideas.

When I first started shooting shows, I decided to only use available light. Pictures shot with flash tended to look all washed out and unflattering, and bright flashes might also run the risk of distracting the performers on stage.

The more recent digital cameras have really great low-light performance, and can shoot at ISOs like 1600 and even 3200 with much better results than their predecessors. Even still - the higher your ISO, the noisier your image, and the less sharp it will look. Not to mention that your camera's going to be shooting wide open, and at a shutter speed that would either require a steady hand, a monopod, or some good image stabilization. And even then - shooting at those slow speeds is still going to result in blurred images, because performers tend to move around a lot on stage.
Sometimes, that's a cool effect, but I thought it'd be nice to get some sharpness, if at all possible.

So I got to thinking - "wouldn't it be great if I could shoot at ISO 400 at like, an f8?"
And I came up with an idea - "light reinforcement".

This is a variation on a term used in the world of live audio, called "sound reinforcement".
The basic concept of sound reinforcement is to take whatever sound is already there, and to, well, reinforce it. Beef it up. The best examples of true sound reinforcement (to me, anyway) are theatrical performances - plays and musicals. These are traditionally performed in a proper theatre, which has been designed and engineered for sound to project off the stage. However, since there are often a variety of elements coming off the stage - different actors/singers, musicians, sound effects - getting everything balanced can be a bit tricky. The way this is typically handled is to put a microphone in front of anything and everything that is making a sound, and sending all of those signals up to the sound guy, sitting at the back of the theatre. From there, he makes whatever adjustments are necessary to keep everything sounding naturally balanced, as if it were coming right off the stage - which, for the most part, it is. But having that little extra bit of support from a microphone and some speakers can make all the difference in the world.

My thought was to essentially use this same principle, but with light - augment the existing lighting with a little bit of my own.
Using a speedlite equipped with a Pocket Wizard, mounted on a super clamp with a ball head (or a magic arm), with a gel or two and either a snoot or a grid (or both), I could effectively mimic what a real stage light would look like. Using colored gels is way more forgiving with music photography, because stage lighting is always colored anyway.
The ideal setup would be to have my strobes positioned right next to where the house lights were already, either clamped to the same bar/grid as the house lights themselves, or very nearby. This would help minimize any "blinding" effects that might occur to the talent on stage, and also maintain the authenticity of the look. With one light on each side of the stage, I was able to get a nice, dramatic cross-lighting effect, giving me a good 2 or more stops of light to augment the existing stage lighting. Keeping the strobes at lower power (1/16 or 1/8) is just enough to make a difference, but not enough to be noticeable to the performers (your milage may vary on this, actually, depending on the size of the venue), and it also ensures faster recycle times and more pops per show.

At the last show I shot, I asked the performers if they noticed me and my strobes, and they said "huh? you were using a flash? I had no idea".
I've tried this technique a few times now, and am confident in the approach.

Here are a few shots of the technique in use:

eye in the sky

Years ago, when I was using my CoolPix 5000 to photograph bands performing, I came up with a neat idea - stick the camera at the end of a pole (in this case, it was a monopod), and get above everyone's heads - maybe even on the eye-level of the folks on stage (depending on the venue, of course).

The first iteration of this technique relied on the articulated viewfinder of the CoolPix, which I would angle facing downward so I could at least get a vague sense of the composition I'd be getting (I say vague cuz that screen is the size of a large postage stamp, and seeing it from 5+ feet away isn't exactly useful). I'd also need to use the camera's self-timer to trip the shutter.

I used to think of this technique as a kind of "fishing"; you angle the viewfinder, set the timer, and then hoist the camera up into the air, hoping you get a decent shot in the time it takes for the camera to make the exposure. Once you see the LCD flicker, you hoist the camera back down again to see what you caught. Repeat.

I don't think I got any award-winning shots from that technique, but it definitely proved itself fun, at the very least, and somewhat useful.

Some time after that, I added two more elements to this technique - a remote control (you could call it a cable release, of sorts; Nikon called it the "Remote Cord"), and one of those little hand-held television/watchman gizmos. When all of these things were put together, I'd have the ability to leave the camera up in the air, and be able to compose and review my shots on the remote screen, tripping the shutter with the remote cable. Pretty cool.

Recently, I purchased a 5 foot boom pole so that I can hang lights directly over things that I'm photographing. Just this morning, it occurred to me that I could replicate my old CoolPix "camera on a stick" rig with my D90.

Here's how I did it:

First, I used a standard umbrella bracket to mount the camera to the end of the boom. I might consider using something lower-profile, like a ball head or some other sort of clamp, but for now, this works just fine.

Next, I pulled out the successor to the little Casio handheld tv I mentioned earlier; this little Coby handheld tv. Unfortunately, you get what you pay for with these things, and the image quality is quite awful. It also seems to have some issue with the proportions of the image, and stretches the D90's 4:3 image to fit the 16:9 screen. But it still works.

Using a super clamp and a spring clamp, I fastened the tv to the bottom of the boom pole. I then ran the 1/8" to 1/8" cable (which came from an old set of computer speakers) from the tv's input to the D90's NTSC output jack.

Lastly, I connected the poor man's alternative to Nikon's cable release for the D90 - this guy - which I got a few weeks ago for another project (which I'll write about later).

The key to really rocking this system is the D90's LiveView mode. When the camera is in LV mode, the image on the built-in LCD is sent through to the video out(s), as well. So I can now compose and review my shots without having to use the "fishing" technique.

The only downside I see to this system is the relatively slow and weak autofocusing system that is used in LV mode. I would imagine that if I were to make serious use out of this rig, I'd probably work at a relatively high aperture, and set the focus manually.

Here are some crappy shots I took of the rig as described above, only using a monopod instead of the boom pole:

Next time I'm out shooting an event, I'll definitely be giving this a try.
