Cinestill 800T Issues

[fdonadio]

I just got off the phone... I called a lab in São Paulo (Brazil) to ask for ECN-2 processing for Super-8 film. They don't do it anymore in 8mm, but they still process 16mm and 35mm. They offer telecine services and — incredibly — they'd be happy to print my ECN-2 negatives to ECP-2 stock (color print film, a.k.a. "slides"!), no matter the length.

I'll develop my ECN-2 at my home darkroom and send them the whole developed rolls to be printed to slides! Yay!

If you shoot Superia 800 in tungsten light, incident blue light will be about two full stops weaker than red light. Since your light meter doesn't care about light wavelength, it will expose for the dominant, i.e. red light channel. You have three options:

1. Shoot at EI 640: this will correctly expose the red channel, underexpose green by one stop and blue by two stops.
   
2. Shoot at EI 160: this will correctly expose blue channel, and give green channel an one stop, and red channel a two stops overexposure, which the emulsion will handle very gracefully
3. Use an 80A filter and shoot at EI 160: this will expose all three color channels correctly.

Note that most in-home lighting is "tungsten" based, at least here in the US, however the color temperature of the average home tungsten bulb still doesn't match the color temperature of tungsten film. I commonly see bulbs balanced for 4 different color temperatues:

1. 2700K - this is the most common color temperature I see, and is often called "Soft White."
2. 3000K - this is often called "Bright White"
3. 5000K - this is often labeled "Daylight" although I occasionally see "Daylight" balanced bulbs with a color temperature of 6500K. Check those color temperatures!
4. 2200K - these are usually the LED bulbs with the antique style filaments in them.

Tungsten balanced film is usually 3200K, and an 80A filter is what you need to convert 3200K light to 5000-5500K (Daylight) balanced film. I've shot daylight balanced E-6 film under 2700K lighting through an 80A filter, and there's a big color difference between 3200K and 2700K! The colors are definitely off when you do this.

-) The colour temperature of plain tungsten lamps varies a bit with their wattage.
-) over here special hues of these lamps were scarce. There lately was some yelllowish tint and there were bluish lamps giving some daylight effect.

Yes, it is true that the color temperature of plain tungsten lamps does vary with wattage. Lower wattage lamps burn cooler, and therefore produce warmer light. So as you drop the wattage, the light gets redder, which requires even more color correction to make it work with daylight.

That's why I relit the scene with 5000K LED bulbs when I wanted to do available light color photography. It was easier to relight the scene and shoot with high speed film than it was to figure out how blue a filter I needed, plus I could shoot handheld! Admittedly, one can't always relight the scene, but for what I was trying to do, this was the simplest approach, and I didn't have to use ISO 5,000,000 film! Plus, negative film gives you the opportunity to do some small corrections "in post" after getting it mostly right in-camera.

I just shot my first roll of Cinestill 800 and I love it. Rated it at 800 ISO. northcoastphoto.com developed and processed it, c41
No filters used, colour was corrected in LightRoom, as I do for all my colour film.

Those turned out nice. I also got good results from Cinestill 800.
