Strobist Boot Camp II - Head Shot

A friend and I decided to participate in the latest Strobist Boot Camp II exercises by David Hobby, (Strobist Blogspot) and for my head shot, I wanted to see if I could use an MR-14EX macro ring flash as an on-camera fill. This image is the result of my test.

The posted head shot here (courtesy of my friend, Fred!) is the result. I had a Canon 580Ex off to the subject’s right with a Honl grid, set on slave and triggered by the MR-14ex on the camera. The MR-14ex was set on manual and since the two strobes are already on banks A and B, I set the 580Ex on bank C. I manually set A and B to 1/64 power and the C bank (580EX) to 1/16 power so it would act as the key.

The result: I believe the MR-14EX can act as an on-camera fill for short distances, perhaps up to 8 – 10 feet. The biggest disadvantage is that one is limited to the Canon macro lenses that support the MR-14EX! In this case, I used the 100mm macro, which is a great lens and the length is good for portraiture.

I shot this with a Canon 5D MK II set on manual mode – 1/50 sec and f/6.3. I am pleased enough to continue experimenting with this setup!!

I’ve been waiting for the Radiopopper Jr. system since last year when they were first announced.  However, the designers/manufacturers of the “Poppers” decided they weren’t happy with the design and decided to pull back and add all the new features that they were going to save for future models.  Now it appears the Jrx. Popper is finally going to be released next month!

What is the Radiopopper?  For all you Strobist junkies out there, the Popper is a radio remote unit for your flash units.  If you are familiar with the PocketWizard, then you know what a Radio Popper is, except the Poppers are full TTL!!  That means the flash units can be used on automatic as well as manual!  These clever guys figured out how to take the infrared (IR) signal that flash units use to communicate TTL information and convert that into a radio signal that can be sent hundreds of feet, instead of ten to fifteen feet.  Even better, since these are radio units, the units do not have to have a direct ‘line of sight’ in order to operate – put ’em anywhere!  The Px units are now on the market and cost about $250 each for the transmitter and receiver.  However, the JRx model is suppose to come in around $50 each and will also work with the Px transmitter unit!

I’ve been using the eBay $25 Hong Kong units, which are unfortunately not that reliable (lots of misfires) and don’t have much range, so I’m really looking forward to trying out the new Jrx which are suppose to be released late next month.  For more information, check out http://radiopopper.com/ and click on their blog link for current status.  As soon as I get my hands on one I will post a review here and at my new forum at www.elusiveimage.net/forum.
