d_g5 Posted August 16, 2009 Share Posted August 16, 2009 <p>I know that they've been just released but just wondering if anyone has had any experience with the paul c. buff plm parabolic umbrellas?</p> Link to comment Share on other sites More sharing options...
d_g5 Posted August 18, 2009 Author Share Posted August 18, 2009 <p>Nevermind ppl...<br> Just got the PLM about 5hrs ago - completely informal testing by the way. OH my goodness! I firmly believe that this thing refocuses nearly each beam of light! The 42" silver PLM (without the diffusion material) gave off F16 for ISO 100 at 1/4 power approximately 7ft away from the tip of the umbrella shaft! (Barebulb at that!!!)<br /> <br /> This is not the F20,000 and the likes that people are reporting but when I shoot fashion i was actually considering the Zeus to get F22 to overpower the sun in broad daylight... Why n the F would I do that now? By the way... this was from a B800. Here's the best part... when I metered a between the end of the umbrella and the umbrella shaft I got 2/3rds more output!!! What does this mean? That I didn't even have it perfectly optimally focused! I guess this is where the new Spill Kill reflector will come in handy - as you will clearly see the edges and be able to line the reflector and umbrella edges up for optimal focus.<br /> <br /> Wow... much more to come! Watch my blog for images made with it at</p> Link to comment Share on other sites More sharing options...
prettygeeky Posted August 18, 2009 Share Posted August 18, 2009 <p>I just received my PLM 64" and 42" as well. Wow, I love the extra output... and I'm just using them with Nikon SB600 speedlights too. They are affordable, and are built very well, much stronger than my first cheapo Impact brand starter kit umbrellas.</p> Link to comment Share on other sites More sharing options...
nathan_stiles Posted August 19, 2009 Share Posted August 19, 2009 <p>Power is a small part-- though I do wonder why they used a material that would allow it to be used as a shoot through also. That should eat some of the light and could have been avoided. How does it work?</p> <p>How is the spill control, eveness of the lighting, what's the fall off like and the focus of the shadow at subject distance? Does it give a double umbera (sp) like an umbrella, or a single dithered one like a softbox?</p> Link to comment Share on other sites More sharing options...
d_g5 Posted August 19, 2009 Author Share Posted August 19, 2009 <p>I have the silver version. the white is softer with less output. I wouldnt use them. Ty Yang... use a barebulb strobe of about 100 watts and see how your f16 looks 6-8 ft away!!! :) I think the 42" is gonna get worked to death!</p> Link to comment Share on other sites More sharing options...
studioallure Posted September 10, 2009 Share Posted September 10, 2009 <p>Is the white PLM without the black fabric a shoot through basically?</p> Link to comment Share on other sites More sharing options...
nathan_stiles Posted September 10, 2009 Share Posted September 10, 2009 <p>Yes. Though they sell a "spill kill fabric", to make it work like the famous Westcott Halo.</p> Link to comment Share on other sites More sharing options...
studioallure Posted September 11, 2009 Share Posted September 11, 2009 <p>I see so the only one that has the black backing is the silver? I've heard of the wescott halo, but never seen the results. any examples?</p> Link to comment Share on other sites More sharing options...
studioallure Posted September 11, 2009 Share Posted September 11, 2009 <p>I saw a few in google but not many good examples</p> Link to comment Share on other sites More sharing options...
