AFAIK, HSS and rear-curtain are not possible with wireless flash. You can get HSS with a Canon ST-E2 (which I've done), but you lose a bit of punch with the flash output. I was quite disappointed with the fact that I couldn't get a rear-shutter synch with the 7D wireless system...

I'm sure I sound like a broken record by now, but both HSS and and rear-shutter sync are available with the PocketWizard MiniTT1 and FlexTT5 trigger system. Radio Poppers may also have a solution, but I'm not as familiar with their products.


Yep, I've tested mine at 1/8000 and it still syncs fine!! Not quite got the rear curtain to work properly though ... only tried it once though

It looks like HSS and rear-shutter are available with the radiopoppers PX transmitter. I got the JrX kit(which seems great so far, have to do some tests outside hopefully this evening) which is all manual. But it looks like the JrX receivers are compatible with the PX transmitter, so if I want to go that route I can in the future. I don't have a problem adjusting the lights manually I just wasn't 100% sure about the sync and ttl with them. I imagine what I will be doing is composing my shots and using ttl to get the ambient exposure then just manually adjusting my flash for fill or key, depending on the circumstances. Will take me a few test shots to get it dialed in but one it is there I will be able to just fire away.

From memory the JrX receivers can do higher speed sync with studio strobes, but I forget if they need a JrX transmitter, or whether it needs to be a PX

Got my radiopoppers and my apollo 28" Softbox in and am very happy. Here is a test shot I did last night. The Softbox was camera left just out of frame angled down, I also had a 430ex on a stand camera right with a diffuser cap on. Both were angled about 45 degrees from the camera. Not sure of the power settings for the 430ex's though since you adjust them on the transmitter but I think the bare flash was down pretty low, maybe 1/4 or less power and the one in the softbox was between 1/2 and 2/3 power.

I just started reading this thread, as I'm starting to get into shooting with off camera flash. I ended up ordering a couple of e-bay 40" Reflective Umbrella Softboxes.



As you can see from the light source in the image, they weren't specifically designed for a flash unit. Although they do fit, I didn't like the way it put stress on the camera-to-radio trigger hot shoe or the radio trigger-to-light stand hot shoe.



Earlier in this thread (Page 2 I think), hoppershowed a couple of solutions he came up with. Here is my DIY bracket for a horizontally mounted flash unit.

First you start with a 5"x5" zinc plated T-bracket. The holes are the perfect size for a 1/4"-20 threaded bolt.



After grinding the corners round (Optional), I bent the sides up to cradle the flash and painted it flat black. I used a hammer and a brick to bend mine but a vise would be much easier.



I then glued padding on the sides of the cradle portion and over the end of the flat section (I used Fun Foam Sheets from a craft store) and then some self adhesive rubber bumpers, high enough to support the flash over the 1/4"-20 hex head mounting bolt. There are several sizes and styles of self adhesive bumpers and felt pads that you should be able to find the combination of sizes that will support your flash.



Then you mount the bracket to your light stand (I needed to add a 1/4" nut as a spacer due to the knob on the light stand) and then I used a couple of DIY Bongo Ties to mount my flash to the bracket.



The total cost of the bracket is about $5 -$6 and as you can see, it lines up rather nicely with the softbox umbrella.



These would also work for regular reflective and shoot through umbrellas.

Nicely done, Tim! To paraphrase Plato, "Necessity is the Mother of Invention". :-P

saw the link to this on the Strobist blog. Simply put. Its the lighting stupid! =)

//fstoppers.com/iphone/

They did a shoot using a iPhone. And of course they couldn't use strobes so they used the modeling lights on their light gear and supplemented that with good old work lights from Lowe's.

I have to say that I was pretty darn impressed with the results.

Pocket wizard tt1 & tt5 with 430exii. I had some issues with the 430ex but none as yet with the 430exii. Only issue in this photo is the softness from the canon50mm 1.4, I was testing at 1.4.

In doing research for a home studio lighting setup on DPC and online, I came across this nice article talking about why a short pulse high Watt-Sec rated strobe is better than a very high Watt-rated continuous light.

P.S. Please ignore if discussed already.

I had not ever really thought about it, but the fact that continuous lighting requires no sync is an important concept that article schmoozes over. Boundless sync isn't something to just throw in as a minor caveat- it frees you IMMENSELY (that's the whole thing we were discussing above a bit). I'm not saying that means continuous is some holy grail, because it DEFINITELY has its drawbacks. (ETA- I didn't realize it probably because I never really put a lot of weight into continuous lighting, myself)
FWIW, the more photography stuff I've accumulated, the more I've understood and supported the maxim of buying what you think you will EVER need, not what will do for the time being. Of course, this approach isn't easy on the checkbook, and it's difficult to determine what exactly you'll need without going overboard, but in the long run it's way easier on the checkbook and you won't be so pissed at yourself.
