Free Holographic Diffuser. Must See!!

Rich Hibner · December 3rd, 2006, 09:55 AM

Wayne, I'm just not too sure what you're talking about because it sounds very tech savvy. But...I do have two of the same exact phones and two of the same exact Sreens. I'll try putting them together and see what I get. It could diffuse more light, but maybe more grain. And what if say you have two 15degree screens, would that make it 30? Could take the bokeh and put it into another direction. I'll check and see what kind of results I get and post up pics.

Wayne M, I tried the double screen to see if I'd get better lighting. I don't think I placed them in wrong angles because the screens were exactly the same and lined up. They have tabs on the side so I knew they were lined up perfectly. The results were more light loss. Here are some grabs.

1screen:

I'm actually surprised to see that the light loss isn't that much with the one screen material(to me). That was under a ceiling fan light at or around 60watts. The fan in the picture is about 6fee from me and the table a good 7 or 8.

Today I did a test in my horribly lit Living Room with the setup I posted earlier.

As the living room is horribly lit, keep in mind that I had to turn the gain on the camera up to like 12db (not acceptable by any means). I was also shooting full open which is a bad idea too, it probably explains the lack of sharpness. I need to play around some more.

Here is another test. Outdoors. I'm really impressed with it actually.

http://www.fmpfilms.com/35/pvctest2.mov

I shot with the nikon at F2.8 and my Pd170 on full auto (At least, I'm pretty sure it was full auto)

The compression does get rid of some of the grain, but you can still see the prevailing black specks. My screen is obviously dirty snd scratched. Since it is wedged between a UV filter and my 3rd closeup filter, You're probably seeing whatever dust is on the closeup filter too. So I need to create more distance between the focal pane and my macros.

Being a bit more awake now, it depends on what sort of screen it is. Some of these devices contain a number of different screen components put together. The ones I mention are basically a series of vertical lenticular lens. You are not going to get the same advantage with most of the other sorts. They would not only need to be stuck together rotated at right angles, but I think with the same surfaces facing the same direction the best. But it doesn't matter keep experimenting, see what you come up with. Go to the 3M sites and like up all the LCD display related filter diagrams.

Got my vibrating unit hooked up now and here are the first grabs. I'll go out tomorrow morning and shoot some stuff in the day w/ and w/o vibration on so you can see the difference.

You probably won't like. But I put it up anyway. You've got 7days to d/l then it's gone. If you want to host it feel free.

Chris Knight · December 7th, 2006, 10:27 AM

You can definately still see the grain when it's vibrating. But I think that it gives it a very filmlike feel to the footage. Others may be more into the completely grainless thing, But I really like the effect.

Rich Hibner · December 7th, 2006, 11:09 PM

Here's the dog footage. Quite a big file 161mb's.

Is it just me or is anyone else having trouble downloading those two .movs from filelodge.bolt.com?

edit:
Nevermind... it worked in a different browser.

Sam Jankis · December 8th, 2006, 12:13 AM

The bokeh is pretty soft, at 0:48 into the Dogs2.mov there is a lens flare and you have the clearest, isolated bokeh example. There's also some weirdness going on at edges... at 1:00 into Work2.mov the edge of the white labels on the wine bottles have a green outline when they go out of focus. Must have something to do with how those particular holographic diffusers work. Also, on these two clips - were you only using one diffuser (not two at a time)?

Still, I think it's decent for uncontrolled lighting. An ND filter or polarizer would probably come in handy in the outdoor shots. Now I'm curious how it'd look with an HD cam.

Rich Hibner · December 8th, 2006, 12:23 AM

whoa, you really analyzed the hell out of these videos'. laugh. Just one diffuser. Two are really really dark and produces more grain.

Sam, do you have an HD cam? I live in Florida.

Sam Jankis · December 8th, 2006, 10:03 AM

Check your email.

Rich Hibner · December 8th, 2006, 03:35 PM

Sam, didn' get anything. I don't know emails are working thruogh here or not.

You can send it here.

New footage. More from work footage. This one won't be deleted. It'll stay after 7days. It's only 37mb's. Added music.

In the clips you can notice grain. So I thought this screen was too grainy, and it still might be, but with what i've learned it might not. I have a WAX gg that was made for me and it's already a decent static adapter with very little grain. I wanted to compare the two. Even with the WAX gg there was the same amount of grain. Now, I've also investigated, that if you have too much voltage going to your motor that it can result to improper vibratation. I never got a chance to get a a Rheostat, which lowers the voltage from the battery to the motor, and I'm thinking this could be what eliminates the grain completely. I hope so anway. I'll post the clips as soon as a I get a rheostat.
