This is an HD Spirit scan by Spectra Film & Video. Wittner is finishing three emulsions for me: V3 50D, V3 250D and TXR.

 

I have some 3383 that I'm thinking of having them finish as Double 8mm, but the workflow isn't quite ready for making 8mm prints yet.

Nice work!

A small critique of your technique:  when you're shooting the cards, and charts, ideally, you need to get as close as possible.

A grey card should fill the entire frame.

A Gretag chart likewise."


With the former, you ideally want to get it big enough to read with a densitometer with a certain sized probe diameter.

So the physical size of the film being so small, it's best to fill the frame with a grey card, each step on a grey scale and color patches.

Thanks for the great suggestions. 

 

I'm just a fumbling amatuer at this point, as you can tell. My goals were:

 

- Provide colorist with something to calibrate with

- Test three Switar lenses

- Check two cameras for registration and gate weave

- Finish two rolls of film quickly

 

What you should have seen at the beginning of each roll is a progression of lenses: 5.5mm, 13mm, 26mm. That is not apparent because I left the lens cap on the middle lens in one test. So for that test, you see too wide and too narrow. That stuff is at the beginning of the film, but the telecine operator put the film in backwards, so the beginning is at the end. That makes it even more baffling.

 

Also, I couldn't find my big Color Checker that day. I looked in all my Pelicans, my A-Minima backpack, and my big A-Minima shoulder bag. Can't figure out where it went. So I had to use that silly little pocket thing.

 

Anyhow, that's my recipe for shooting a mediocre test film, but one which tells me if the camera has gate weave or registration problems. :-)

It's satisfactory, but you want to photograph the checker at the same physical size on 8mm film as you do on 35mm film.  It should get bigger and bigger the smaller the format you get.

It is not just for video correction, it is so you can check the processing and color and exposure on a light box as well, or with a densitometer at the lab.

The size of the aperture on the densitometer is maybe 1/4 to 3/8" (7-10 mm) in diameter.

Oh, that is very useful information. I hadn't thought of that. It sounds like I need multiple shots to get color checker squares the correct size on the film.

 

Thanks!

Right, in most cases, a full frame with each color or step.
