The Kodak Portra 100T is a color negative film that is particularly suitable for true-color pictures in artificial light (3200K). The “T” in its name therefore stands for Tungsten. With suitable filters, use in daylight or with flash is possible, which expands its range of applications.
According to the manufacturer, the Portra 100T is particularly suitable for interior design, advertising and industrial photography, and copy work. But this film is also well suited for long exposures. It can be used for exposure times from 1/1000 of a second up to 120 seconds.
Development
If you still find a roll today, you can of course continue to develop it. To obtain finished images from film strips, the film stock must be developed when the film is full. For this purpose, it is subjected to a standardized C-41 development process, which is carried out by most photo laboratories.
Development is especially easy at common drug store chains. The developed negatives are the final product of the development process and can be scanned and printed, for example. It is also possible to make prints in various sizes directly during the development process at most photo labs.
Digitization
To further process the images digitally, the film strips can be digitized with a scanner. There are professional photo scanners for the best scanning result, but also scanners for home use in different price ranges. After the digitization process, various options are available, such as further digital processing or printing the results.
Formats
Due to declining demand, Kodak discontinued it at the end of 2006. Prior to that, it could be purchased for 35mm, large format and medium format cameras.

What cind of filter do I ned if I take photos whith this film in daylight.
If you are using an analog 35mm film intended for tungsten light (typically balanced for a color temperature of around 3200K), and you plan to shoot in daylight, you will need a color correction filter to adjust the film’s color balance for the higher color temperature of daylight (typically around 5500K).
To achieve accurate color reproduction, you would require a blue color correction filter, commonly known as a “daylight” or “80A” filter. This filter is designed to cool down the color temperature of the light entering the camera to match the film’s sensitivity. The 80A filter typically has a strong blue tint and is used to balance the orange color cast that tungsten film would produce under daylight conditions.
By attaching the 80A filter to your camera lens, it will effectively compensate for the difference in color temperature between tungsten film and daylight. This adjustment will result in more accurate colors and prevent the image from having an undesirable warm or orange cast.
