todd: are these straight out of camera? Or did you do any PP? If straight out, it looks nice and contrasty w/o being harsh...

they were jpegs (not raw) sooc except for some cropping on the puppy shots so there is some sharpening but i think my jpeg contrast is set to 0
and to save the next question 5d2 with 85 1.8
i planned to put all that in the post but forgot with the kids and puppy around haha

Dear Todd & Friends

I agree with Kenyee about your images having lots of contrast but not being too harsh.

Nice looking young man and pup!

Thanks Todd. THe shots look great!!

I actually prefer a detachable disc as it stores and transports better in a sense that you can put something else inside the BD (be it a smaller modifier or a reflector) without worrying about bending the disc. I would also think that Paul can manufacture different kinds of disc to mimic a variety of color temperature - very similar to Elinchrom).

Is this thing heavy??

I think most of them were the dirty white bg and i would have photo chopped them out but left these the way they were

the white paper is old and very dirty but i am moving everything within a week and i'll cut it off then

but i am going to check the sensor

Todd

was it just one light set up with the BD for those photos? If so, what were your settings, approx distance, etc?

it is pretty light. all aluminum

the removeable piece is growing on me and it is super easy to use it seemed like a extra step but it is so minimal i may end up liking it that way

Up fairly close to the modeling lamp - about 1/2 to 1". The closer it is the less spill. But don't put it so close that it shadows the outer edges of the dish.

Hey guys.. Sorry if this has been already answered. But I'm very interested in the new High Output BD. What F-stop can you push @ ISO 100 w/ 640ws at full power? With the sock & w/o the sock at 10feet?

Paul... any word on the new high out put reflectors? What F-stop will those likely push @ 640ws? How will they compare to the regular reflectors & long throws F-stop wise?

thanks,

-Alexis

I get f22'4 at 10' ISO at 640WS at ten feet from the raw 22" dish, with 45° coverage, then broad feathering typical of a shallow reflector. The sock drops it 1 1/2f but widens it out to about 150°. I'm trying to get some beam and output pix up, but I keep having to repaint my grey wall to get it even. Then found the problem was a stud sticking out and causing a less than flat surface . . . frustrating!

I'm remaking the 11" long through for the forth time. Also prototyping a 15" long throw. This should be extremely hot. My comparison is Elinchrom 16" 29° on RX 600. It really sucks - dead center and you see the flashtube projected on the wall. Our standard 11R beats it on axis - the Eli projects a bright ring around a dead center. The 8 1/2" is working well at about f22'4. I could get more by making it shallower, but then you get a lot of spill.

When you do the vectors you quickly find deep reflectors must also be big diameter or you just compromise the parabola and don't get as much output as a shallow version.

The winner every time is the Silver PLM because 100% of the light is focused. I'm getting f22'8 or so with 320WS - 10' with slightly reshaped proto, and very even coverage and sharp cutoff. Current shipping PLMs are close to this when critically focused. Working with a more reliable vendor to improve every aspect of PLM series, including 7mm short shafts. but not apologizing for the current version. This stuff is an art and I am human learning to refine the art.

What do you mean "from the raw 22" dish" is that without the direct-light blocker or with it on?? Is the 8 1/2" reflector near shipping at all?

I would love the PLM but unfortunately... I work a lot outdoors and the 86" PLM would be like a sail boat w/ any amount of wind. And around here, there ALWAYS wind (at least whenever I'm shooting). That's why I'm looking into the High output BD and looking into the high output reflectors.

Thanks!

The 8 1/2" reflector mold is being textured - should have new sample toward the end of next week, then about 20-30 days production and we'll be ready.

"Raw 22HOBD" means without blocker or diffuser. Output with blocker is essentially identical, but with a bit less spill. The sock drops the output and widens the beam. The 22HOBD would be a good alternative to the PLM outdoors, as will be the 11" long throw once I get it right. The king should be the 15" that is in prototyping now - about three weeks before I have answers.

I'm crossing my fingers that V21 of the Cyber Commander firmware may make it shippable in a week or so. We have 500 built and ready to update the firmware (easy to do via CC's Micro SD card.) Good progress on what was AB Max and big surprises . . . it will be re-branded Einstein 640 - because that's basically what it's become. We have prototyped my power supply and all the IGBT circuitry in house and it works fine. But it will still take about two months to bring it together.

A word about Cyber Commander and classic Buff lights . . probably not for the casual user as it takes specifying what classic Buff light is connected to each channel (via CSR+/CSRB+) and the wattage of each modeling lamps. It will not require any extensive setup once the next generation Buff lights are available - because they automatically communicate everything to CC. You have to consider CC is more like an iPhone or Palm than anything now on the photo market.

There I go again - pre-releasing info that I'll probably get jumped on for . . . I'm only human. Interviewed and panned four engineering candidates this week - it's like pulling teeth.

Thanks for the update. Looking forward to CC.

The 8 1/2" reflector will be more suitable for replacing or supplementing the current 7" reflector. It produces about 8/10f more output than the standard wide angle 7" reflector over about a 50° field (instead of 80°) and is very even and nicely feathered. The physics of studio flash demands a larger diameter reflector than this to produce really highly concentrated light without a lot of wasted energy and spill.

So the 8 1/2" should be a good smooth and efficient general purpose reflector. I'm getting about f22'5 at 10' with 320WS.

Paul, if you replace the 7" reflector... will there be new grids?? I hope they are not replaced...
