The Gs35

[Car3o]

I just made that adpter name up, but here's a clip of a wax diffuser. All parts readily available through the internet and no glueing, hacking, sawing, grinding anything. Just screw on. I have a vibrating version coming around next week.

It's a divx file and only 40mb's big. I do notice spots on the screen. That's because I dropped the glass and it put little spots on it.

I tried to open but an error occurs. I'm downloading it again.

Not to bad at all, was this with the new achromat?

Cant really see CA or barrell distortion, just a little vignetting and the GG grain.

Can you remind us of your setup?

Also, I can see that your wax GG is not really diffusing enough, giving that hazy bokeh (sometimes known as ghosting). Unless you like that look, and it does give less lightloss this way, I would try a slightly thicker wax layer.

Wayne it is with the new achromat. I had to pair it with another one from a binocular. Wasn't enough power? The major amount of vignetting is up in the right hand corner and that's where all the specs were also. It did a lot of something when I dropped it. I have 2 more screens I'm going to test out that are a little different. Yeah, I agree. It loses a lot of light already. The setup is with a thorlabs tube. Also the screen is a really small micro slide. It's placed inside a 49mm filter ring. And that's pretty much it. Nothing great.

What is the distance between the GG and achromat and camcorder? That achromat is certainly powerful enough (more so then the century optics +7).


Also about the vignetting, are you not using a condenser lens (PCX or DCX)? You will certainly get some vignetting if you do not have one in place.

Wayne. I'll look up the measurements for the macro and let you know. I'm not doubting your macro at all. The only solution I had was to pair it with another one. And even so, it's real nice because I don't have to zoom past 77 like I was with the cheap Opteka's, and much more crisp image. I'm sure the distance I have is too far because the holder I'm using is .5 inches long and the macro sits two step rings away from the camera. So just guessing here. 72-62-52ring(macro-.5inches)----then screen. I'd say the screen is at least an inch away because the thorlabs tube is 2inches long and it doesn't go all the way to the back. I don't have a condeser. I do think the most of the vignetting is from the screen being cut off on the edges some. It's in a UV filter mounted in, possibly. What FL pcx/dcx would you suggest? Plus the wax was/is not spread all the way. The sides have lots of weird things. It got beat around a lot. My cat likes to play with things that don't move??? I have some semi outdoor footage later if I can manage to stay awake.

Most start with a PCX or DCX of 100mm FL

Here is some more footage. The smaller clip is from a a day ago. The larger clip was from the same night as the previous clip with the fan, but not as much vignetting. I must have had it not zoomed in like I thought. Enjoy. More to come. Some with vibrating hopefully. Anyone want to take a stab at some POC material with me? I just don't want to spend that much on one sheet.

Just a friendly tip here. You gotta whitebalance before you shoot. It's hard to evaluate the footage with the colors you posted on the outside shots.

[Car3o]

Just a question about white balancing. Do you balance with or without the adapter on.

[rawfa]

You white balance with the adapter attached to the camera, because the use of the adapter will impact the white balance results.
