Recently Steve picked up a Dynalite 91″ (2.3 meters) RiME Lite softbox. His first impression is a mix of positive and negative. The positive is without the diffuser it is a highly directional “softbox” that, as you can see above and below,has a pronounced cutoff and is very efficient in concentrating the light.
This shows the initial setup with the softbox as the primary light source. The RiME Lite is about 125+ feet (38+ meters) from the man grinding the pipe and is connected to a Dynalight M2000wi pack set to 2000 WS using a Pocket Wizard Mini TT1 hotshoe mounted transmitter to sync. As you can see we have the RiME Lite attached to a fully extended Matthews Hi-Hi Roller, about 22 feet up (6.7 meters).
This is the first of a series of images shot on this location.
This is one of the final images:
This is from another series where the 91″ RiME Lite is providing the main light.
This is the setup:
Steve comments, “As you can clearly see there is a ring of hard light produced by the Diffuser not fully covering the softbox. And not trying to be rude, this is just stupid. I do not think this is caused by Dynalight, from my experience they are not stupid. As for RiME Lite, I can’t understand their thought process.” (SEE updates below) He continues, “I am going to keep the softbox but it will not always the best solution due to having a built in problem. This is not normal for me, I do not normally keep a product that limits what I can do, this one does have limitations but as a softbox w/o the diffusion panel it is great. I just do not know why a “Lighting” company would do this.” Steve said he would like RiME Lite to bring out a properly sized diffusion screen that would make this a great product vs. a limited use one due to an unfortunate design flaw.
UPDATE! October 7th, 2015
In communicating with RiME LITE in South Korea, they know this is a problem and they are sending Steve an “outer diffuser”. He is not sure what this is but he will report back after testing!
UPDATE!!!! October 12th 2015
RiME Lite sent Steve the “outer” diffuser, which fits on the outside of the Grand Box 91 giving full coverage. This is Steve’s response:
“It is not out of the same material as the internal baffle, which is a denser white fabric, but I think for my application it may work better.”
After testing the light transmission of both fabrics, this is what we found:
The internal diffuser (Supplied with the Grand Box 91) reduces the light by 1.5 stop.
The outer diffuser, which is made out of white rip stop material, reduces the light by 1.3 stops, so the outer diffuser is more translucent. Meaning it “Uses” 0.2 stop less of light and means it likely does not make the light as diffuse. (Less Softening).
Steve continues, “I am totally excited by this panel, it totally solves the problem with the internal diffuser. I think it will give me what I was looking for. I tried out the Grand box for a client shooting in spaces the size you see in the photos above. Normally we would light a very few scenes, relying mostly on the overhead lights for the primary light. This was done only for time constraints, not because I wanted to shoot with ugly light.”
Steve explains, “After shooting in a massive warehouse with nothing but an occasional florescent light and having to use 2500 or 5000+ ISO to get to f2.8 1/30 or 1/60 second shutter speed and being unhappy with the results, I started looking for a solution to this problem. The Grand box 91 solved this lighting problem and did so with ease. I do want to thank Hwan, with Rimelite & Hyundae Photonics Co., Ltd., for sending us this panel. It totally eliminates the problem.”
