hi all, just to share a "radio trigger test" with the 120J that I did a few weeks ago.
There are two + 1 ways (that I know of) to control ambient light, one is to shoot at small aperture (F11,16,22) to limit the amount of light, but you need to combine a few hot shoe flashes or a minimum 200Ws strobe to compensate it. You can refer here to know more by the great one light master Zack Arias.
The other way is to shoot at higher flash sync speed to cut down the ambient, I prefer this method, Why? Using higher flash sync means that I can use less powerful flash... This method have a catch though, most of our DSLR only have flash sync ranging between 1/160, 1/200 and 1/250. So how to shoot above flash sync, well you can switch to medium format or buy a used Nikon D40,D70,D70s,D1, D1H and D1X. There are also some prosumer compacts like the Canon G9 and G10 which can sync above 1/500. But lets just concentrate on DSLR cams.
Before I go in-depth into the testing scenario, some of you may ask what is the + 1 method? For the +1 method, you can refer here which I learn from the great Yoda of Strobist, David Hobby.
As mention before on page 1 thread two,my Sony A100 have a sucking flash sync of 1/160 :sticktong. So after waiting and waiting... I finally got my hands on a used D70. This cam simply rock my strobist world. I finally got to try things that I can't do... Shooting at flash sync at 1/1250
Yes sir, you are not reading it wrong. Flash sync @ 1/1250sec. The pocket wizard truly can sync @ 1/1250sec with the Nikon D70, now come the other surprise, I own a few China-made PT-04, normally these trigger according to manufacturer only have flash sync of 1/250.
These PT-04 can also sync @ 1/1250 with my D70,
surprised!
The Radio Triggers
I will be using the Pocketwizard Transceiver and "Ishoot" PT-04 trigger.
Sorry for the badly taken photo, I only got less than 30 mins to get everything done and returned the PWs. So everything must chop chop.
The Test setup
Very simple setup, two black boards acting as base and background, a 120J+grid mount onto a boom with power set @ 1/16 the lowest power setting. Please ignore the reflector in the image. The reflector was not used during testing. Nikon D70 mount on tripod with a Tokina 28-70 F2.8. All the images are taken with a wide aperture of F2.8 to illustrate the change of ambient light when I increase the flash sync. I try to placed the product as closed to the windows as possible. The time is between 1155 to 1230hrs. Very bright sunny day.
I will updating shortly with the results and my personal thought for this test. Do stay tuned
