DOF Adapter Grabs

GG acts as a projection screen from the SLR lens. The SLR lens projects the image upside down, so you have to Flip the image 180 degrees in post. Your DVX lens films the ground glass getting the SLR image projected upon it. Depending on how good your ground glass is, depends on how good your footage or Image looks. There are a few ways. Already stated previously, of how you want your GG to be, static, spinning, oscillating.
 
Can you just insert another lense, or anything else that would FLIP the image right side up again? I'm just thinking that if you were on the fly with any kind of stability system, it would take a LOT of getting used to trying to properly frame your shot in reverse (up is down, down is up).

Yes, but each element absorbs some of the light. :(

What we really need are gravitic lenses, but that requires a small singularity... which comes with its own problems. (Like how to avoid Rhode Island being sucked into the black hole during filming. I mean..there goes the completion bond, right?)

Here's the irony: the image being delivered to the dvx is rightside up, the dvx just flips it upside down since its lens delivers an upside down image. Crazy, huh?

Anyhow, the price for a pentaprism that would deliver a large enough flipped image is around $5,000. In other words, it's not a reality except for the P+S mini35, which has one.

You can use a magnet to flip the image upside down, but it's still reversed right to left. I did some steadicam work with the adapter and it's super smooth. With the 28mm lens and the "film-like" softness, the camerawork looks ultra smooth. But...it's hard to frame when the frame is flipped 180º and stretched (I used stretch mode) so a lot of it is screwed up. Still, it's not unusable, and you can mount an LCD and invert it. Also, FCP and most other NLE's flip the image as a real time effect. Is it a pain? Yes. Is it as bad as I thought it would be? Not quite as bad....
 
Just finished a wax adaptor for a VX1000, and it's incredible.

I use an external monitor, so I just fliped it upsidedown for a "regular" looking frame. rad.
Also, you could make a mount to use the actual CAMERA UPSIDEDOWN??? Need no fix in post...?

Bikefilms, have you found any better ways for applying wax? I'm struggling with this right now.

And yeah, I've tried shooting upside down but uhh....how many tripods mount that way? It is one solution, though.
 
man, I just followed the directions on the comcast link. I am using a regular gas oven at 220 degrees. My first attempt rendered a lot of grain, vignetting, and a hotspot. I came back, stuck the filter back in the oven and added a few shavings more of wax. No issues now; no hotspot, no vignetting, less grain. I am also using stacked +1,+3,+4 closeup filters, instead of a +10. This has eliminated vignetting for me.

Thicker wax was key, I think. I used scented wax in this experiment. So my adapter smells nice:)

ps~ I'll post screengrabs and a product still if my HTML is enabled...
 
Nice shots. Very soft though. (as mentioned)

Though, people post still frames all the time... shooting stationary and moving are two vastly different things..

focus pulling would be pretty hard with this.... it be interesting to see how well someone could focus pull with this sort of rig...
 
The "look" is phenomenal though. The moving images are way nicer than the grabs. This cheap adapter will be standard equipment by the end of the year, guaranteed.

Focus-pulling is a pain in the butt. Most of the SLR lenses I've had take 2-3 complete turns to go from here to there. Unless the camera is mounted in concrete, it shakes all over the place.

Know what? I'm not nearly as thrilled by the look as I thought I would be...but I really really like being able to mount different lenses for different occasions. That 300mm is sitting there, calling to me...

Yes, everyone here is aware of that. In fact, 35mm adapters have existed prior to the mini35, and "camera obscuras" (the basic idea behind the 35mm adapter) have existed since the Italian Renaissance.

One note about wax: in my experience, beeswax is less grainy than regular wax, but apparently microcrystalline wax is even less grainy and can be applied more smoothly. I've been very impressed by how organic footage looks with an adapter, but I think it has something to do with the controlled flare effect a layer of wax has that kind of smooths out highlights and increases dynamic range in a weird way. Unfortunately, this does come at the cost of light loss, since the thicker the wax, the more diffuse the highlights.

As for softness, the resolution isn't SO bad, but wow is rack focusing hard. It drives me nuts just getting something in focus and keeping it that way.
