hello ! i have one question to ask...

i shot with super 8 mm kodak 200 vision T with 4008 ...

i would like to shot at dawn (with the slightly blue dominat) and at sunset (with the kelvin "fit" the color temperature of the film)

could we told me if i d like to mount daylight conversion filter to " keep" the original "color atmosphere"?

The both situation require a subtle "adjustment", regarding to the aesthetical rendering you want.

If you shoot in a bluish mood at dawn with no filyer and a T film stock, it will defenetly be very bluish.

If you want to keep the bluish atmosphere but not to correct to "flat" color balance, you can use a 81 EF instead of a 85 for instance.

for the sunset you can try with no filter, it might be a bit orange or just "flat", depends a lot on the scene... You can use a 85 C to lower the orange effect, for instance, but if some shades are in the frame as well, they would look blue... A 85B/85C grade filter can be an option...

I think the best would be you to shoot some tests...

Just a 2 cents...

Color temperature of various light sources:

Conversion filters:

Light balancing filters:

In general, when you shoot color negative film (Kodak VISION2 200T 7217), you have quite a bit of flexibilty in grading the image to achieve the "look" you want. But if you want a "neutral" rendition, try to filter to match the film sensitivity (i.e., 3200 Kelvin tungsten).

Are you familiar with graduated filters? For example you can use a graduated
magenta filter in combination with an 80A. This for example could make the
sky over water more magenta and water below the sky more blue. The grad-
uated filter can give you more detail in the sky,instead of the sky being blown
out with no detail. The density of a graduated color filter can be increased by
adding a graduated ND filter. Both color and ND grads can affect the look of
your sky. Tobacco,grape,blue,magenta are some of the color filters available.
Lighter graduated color filters add color to the sky,add a 0.3 ND and you can
increase density. Lets suppose you have an overcast day,gray day. Put an 85B
on the camera and you can produce a beautiful sunset. Add a Tiffen Pro-Mist #
3. The Tiffen will scatter light from bright areas of your scene to darker areas of
your scene. This probably would lower the overall contrast. Sunrises and sunsets
are dominated by moments of warm wavelengths of light. If you want more blue
in the sunrise,you'll have to chill or cool down the warmth. The 82 series produce
light blue and the 80 series produce medium blue. The 81A filter will warm the blue.
