Must see! Free Light Shaping Diffuser.

Right. Understood. How does one measure the actual diffusing thickness?
With holographic diffusers, to the best of my understanding, they operate similar to
ground glass but, with better light randomization. So yes wax is quite different from
gg but, the substrate for the HGD also absorbs a generous amount of light in addition
to the actual diffusing surface. That's really what I meant to say:) My fault for being
too general.


Obviously we need to try the diff degrees of film to see which one works best.

No problem at all. BTW, I’m no expert on the subject myself. Now I don’t want to hijack this thread, so back to the original subject.

I watched the clip and thought it looked very good. :)

Cheers
 
Don't worry, i'm not going to think someone is hijacking a thread. I dont really care. So, over at dvinfo they've gone far with holographic diffusion and had tried every possible degree. From Alain's results he said 15 degree was the best, being that it's thickness was minimal, grain was fair, and bokeh was great. So that's why I said 15degrees. 20 was a close second and 30 was too much light loss but finer grain. I had hoped that the vibrating unit would get rid of all the grain, but it looks like it's not going to happen.

Would anyone happen to have a full resolution clip from the G35? I've seen so many, but all were scaled down to 640x480 or less.
 
Car3o, I have to say that the footage coming from the screen is fantastic. I love it.
I'm sold. Sure some might consider the grain bad but, I really think it adds to the
look. Great work!
 
cool stuff! One question though Car3o, how did you mount the diffuser in your setup?
I have the film from a PSP in hand and it's quite flimsy.
 
I watched the first video (Work2) and REALLY liked the look of it. The tone of the clip was really nice, and the bokeh was outstanding. It made the subject in focus really stand out. I'll download the other videos tonight, but I'm VERY impressed by what I've seen so far.
 
Alright, so, I've got some news to share. 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 be. 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.

Dan talked about oscillation with his adapter a bit and he addressed it with
oscillation speeds according to shutter like 1/24 and such. Thus eliminating
any grain with reduced current draw. So when you get your rheo you can
sorta adjust for shutter speed to eliminate your grain but, not as accurate
as his design maybe. I'm not completely sure I'm in my own testing phase hell.
 
Hi guys,

with every gg-holder I ship there is a voltage recommendation. You absolutely will need a rheostat i.e. "25 ohms / 3-4 watts" to control the right voltage.
For the vibrating gg-holder "VH-51" 0.8 -1.2 volts are recommended if its too high it wont vibrate properly and you will see grain. The other thing is you have to fix the the gg-holder inside your tube because it has to be surrounded by mass or the vibration also wont work properly and grain will be visible. Every gg-holder that I ship is tested on a dummy-35-adapter and there is no grain visible. If you use one duracell AAA battery with 1.5 volts thats is too much.

best regards
Daniel
 
I recently purchased one of Daniel's vibrating gg-holders, and I have to say it is rock solid. Excellent product, and far better than anything I could ever have hoped to make myself, or even spec out. Don't waste any more of your time - pick one up now.

New footage. More of work footage.

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

Car3o, where did you get the holographic diffuser used in this shot? (if a cell phone, which one? What are the specs of it?) This is exactly the look I am going for - excellent job.

Really nice, shallow depth of field. Would dialing down the f-stop even 1 stop to increase the depth of field a bit have been possible with this diffuser , due to its light loss characteristics? Looks like you had a little wiggle room on the exposure.

Thanks in advance for your replies. Great job.
 
Guys,

Daniel's product is superb. I don't want any of this footage to turn anyone away by thinking his product isn't top of the line.

I do believe it was from a Audiovox cdm9900. The Samsung carried a scratch. So i tossed it. I'm sure it's possible. I have a canon lens so I'd have to jam to metal piece to stop down some more. I will give it a shot and see what I can get. I just can't wait to get my rheostat.

Funny you posted. I'm in the process of putting it together. I won't be able to get footage until tomorrow because I got the wrong drill bits. Too small. But in about 5mins I'm going to post pics of the setup.
