review: RadioPoppers P1

September 9, 2008 Neil vN 19 Comments


[ click on the photo to see a larger image]

Apathy Angel against the backdrop of the Manhattan skyline.

The settings for the image above was 1/2000 @ f1.6 @ 100 ISO, and the reason for the wide aperture was that I wanted to have the skyline appear as that dreamlike haze in the background.  The bright light though, forced a very fast shutter speed.  In this case 1/2000th would let the background over-expose a little and blow out somewhat, but give me some detail.   But to control the lighting on my model more specifically than just the available light, I used flash.

For the lighting here I used a speedlight in a Westcott Halo softbox (B&H) held up on a monopod by an assistant. This would give me directional but soft light on my model, Apathy Angel.

A year ago, to trigger an off-camera flash, you would have to rely on radio transmitters (such as Pocketwizards for example), or wireless TTL control.

With the traditional radio transmitters, there is no intelligence, and the off-camera flash would be in manual .. which has worked very well over the years. A real limitation would be that you’d hit a ceiling with the maximum sync speed. This in turn would force a specific aperture on you unless you started using neutral density filters and such to give a wider aperture in bright light.

Wireless TLL, in conjunction with high sync-speed flash technology would allow you to to go much higher shutter speeds (and hence wider apertures.) This does come at the cost though of reduced power (and therefore reduced range.) One of the big problems with wireless TTL, is that you need line-of-sight to control your other speedlights. This eliminates using the speedlight in an enclosed softbox, or in a position out of sight.

In the past year there has been incredible buzz about a new product, the RadioPoppers, which would allow any speedlight and camera capable of wireless TTL flash, to be controlled even when not in the line of sight of the master speedlight or flash controller on the camera. This is a huge benefit to photographers that need a reliable way of controlling TTL flash without the hassle of staying within a specific range and direction of the slaved speedlights.

The additional benefit is that high sync-speed flash photography can also be used with much greater ease and without the need of line-of-sight control.

That’s the background. Here’s the review … do the RadioPoppers work? Yes, very well!

 

In this next image, I asked my model to walk towards me, while my assistant moved alongside me with the softbox. I set my initial flash exposure compensation to give me a correct amount of flash for this scenario of the model wearing black against a bright background. I did this by simply checking my LCD preview.

Here I wanted more depth-of-field than in the image right at the top, so I stayed at the max sync speed of 1/250th and selected an appropriate aperture of f5 at 250 ISO. (The 1D mk3 has a max sync speed of 1/300th but I usually stay at 1/250th because I find it easier to work with 1/3rd stop changes, and the jump from 1/250th to 1/300th is incrementally small for any change in exposure.)

.
The next image was taken at 1/250th @ f8 @ 100 ISO since I wanted the background to be well exposed. I then used the speedlight in the softbox to throw light on my model. Since in this instance I was using TTL flash (controlled via the Radio Poppers), I just had to make sure I was within the range of what my flashgun could give out … and then I controlled my flash exposure with my flash exposure compensation button.

If this had been with manual flash in the softbox, it would’ve been as simple as asking my assistant to move closer or further away, in order to control my flash output. But with wireless TTL flash, I could control the output from my camera. For me it becomes easier to make minute changes from my camera without the need then to give continual instructions to my assistant.

I love the simplicity of using manual flash off-camera, but having this kind of control via my camera of TTL flash gives me even more options in lighting with flash.

A few more images:

1/500th @ f4 @ 100 ISO

.

1/250th @ f5.6 @ 200 ISO

.

1/2000th @ f1.4 @ 100 ISO


.

A little bit more about the RadioPoppers themselves:

The technology behind this is a remarkable bit of reverse-engineering. And not only that, the final product opens up possibilities with flash photography that had not existed before.

The downside to this being reverse-engineered, is that the actual bits and pieces of the equipment are not as slick looking or as simple to mount as the usual off-the-shelf gear we can buy. But for most photographers who can see the potential that the RadioPoppers offer, this is a relatively minor issue.

The only real negative that I found with the RadioPoppers is that you need a screwdriver to change the battery. This could be a real problem on a shoot.

The RadioPopper transmitter is this small box which just sits on top of the master speedlight. It is held in position by strips of Velcro that comes with the kit. (I added the hairband that I stole from my daughter, to keep it firmly in place.) There are no connectors, since the RadioPopper transmitter picks up the necessary signals directly from the speedlight itself.

.
The RadioPopper receiver sits on top of any of the slave speedlights. (In the photo shoot above, I only used one slaved speedlight.) This is where the RadioPoppers aren’t as elegant as it would have been if any of the camera manufacturers had envisioned this technology. To send the necessary signals to the slaved speedlight, there is a fiber optic cable that runs from the RadioPopper receiver and needs to be anchored over the infra-red sensor of the slaved speedlight. I used a piece of gaffer tape to hold the fiber-optic cable in place.


.

To sum it up, I am impressed with the relative simplicity of using the RadioPoppers. Anyone who is familiar with wireless TTL flash will immediately be able to use them, and find a use for them.

    Thank you for sharing your thoughts on these. I’d heard about them, but wasn’t sure how they differed from PocketWizards or other remote triggers. Appreciate your providing settings info., too!

    I agree that it would be great if the major manufacturers would include this technology in their equipment instead of a third party add-on. It would be a much neater setup.

    -Neil, have you used these as a wireless method to adjust the power of a flash that is set on manual?

    Hi Neil,

    Love your work! I was going to buy a couple of pocket wizards to replace the ST-E2 setup I have at the moment. You have totally swung me in a different direction. Thanks for the tip!

    regards

    Hi Neil,

    as usual, beautiful work, man! I am so glad you put this out there ’cause I’d been hearing buzz about these Radiopoppers and was very interested in seeing them in a practical shooting situation. I’m glad you were the one to do it ’cause you’re always very thorough. Thanks for this and I hope to see you soon at one of your workshops!

    Take care,
    Jesse

    Hi Everybody,

    Neil, thanks for the review! I have a question and a few comments below.

    I’ve had the RadioPopper P1 system for a few weeks now and really love using them.

    There are 3 ways that I’ve used the P1’s:
    1) ETTL flash: ST-E2 as the master, remote 580ex & 580exII set to ETTL
    2) Manual flash: ST-E2 as the master, remote 580ex & 580exII set to manual
    3) Manual flash: 580ex as the master, remote 580exII set to manual

    By far, my best experience has been #3 above. With this setup, I can actually control the manual output of the remote flash via the controls on the master 580ex (on camera). That saves me the pain of physically going to the remote flash to dial its manual output. It also gives me the consistent output that I need. With that consistent output I’ve really been able to take creative control from the camera position. Also, the on-camera 580ex can be run with its output optionally disabled.

    #2 above requires time-consuming walks to the remote flashes to dial their output. Same end result as #3, but wastes valuable time.

    #1 above yields flash output that varies WAY too much to really control it. With inconsistent exposures, there’s greatly increased time spent in post production workflow. Not efficient.

    Question: Does anyone know how to (or if it’s possible) to control the manual output of the remote flashes via the ST-E2? I haven’t been able to figure that out. I’ve been able to control the remote’s ETTL FEC, but that’s it so far.

    Thanks everybody,
    Russ

    Hi Neil,

    I’m just curious why you use an Apollo instead of a Halo. Wouldn’t the Halo be softer because the flash is a lot further from the front diffuser than it is in the Apollo? Also, with the Halo Mono, the flash is outside the box so it’s easier to adjust (which wouldn’t matter when using Radio Poppers, but would with manual flash triggered by a PW.) Just curious!

    i have been waiting for this review, from a working pro who used them to expand their creativity using the technology. i have been hesitant to invest in them as they add another layer of technology between the trigger and the final image. my question is bridal portraits aside do they have other reliable uses? can you take 3-4 speed lights and put them in a reception room and control them reliably?

    i equate the RP’s to the video light craze, highly specialized situational lighting that’s expensive, and in this case, sometimes unreliable.

    Joe ..

    I do think that anyone who is used to controlling manual off-camera flash via Pocket Wizards (or other radio slaves), and can get great results every time, will be less drawn to the Radio Poppers.

    But for anyone who has dabbled with Wireless TTL, the Radio Poppers will free them up from the line-of-sight requirements that the usual Wireless TTL setups requre. So the Radio Poppers will be exactly what they have been looking for to give them reliability there.

    I haven’t tried them to control additional lighting in reception rooms yet. I’m too used to my Q-flashes there.

    Neil,
    Have you any experience with the second generation RadioPoppers (the PX system)?
    https://www.radiopopper.com/products

    It looks like they have done away with the fiber optic cord on the receiver. They seem to have a trade-up offer too, so you might be able to get credit for your P1 units.
