Fuji Velvia
The Fujichrome Velvia 50 slide film is a film of the brand Fujifilm Ltd. based in Japan. It is an ISO 50/18 degree daylight reversal film and is calibrated to an average color temperature of 5000K. The maximum contrast range of the film is 1: 1000 and approx. 10 f-stops dynamic range. The film creates high contrasts and intense colors with a fairly neutral color balance in the gray axis. It can easily be overexposed or underexposed by up to 1 f-stop. As a result, it can be used very well to reproduce landscape, autumn, sky colors and sunrises and sunsets. Due to its fine grain (RMS 8-9) and very high resolution of approx. 40-55Lp / mm or 80-110l / mm (contrast: 1: 1.6), it is also suitable for high-quality material and architectural photos.
The Schwarzschild effect occurs in long-term exposures of about one minute . With correct exposure, its resolution for 35mm film (24x36mm) corresponds to approx. 5.5-10.5 megapixels, depending on the contrast of the subject. In practice, values around 6-8 megapixels usually result when using a tripod and a high-quality lens. The film is developed in the E-6 process. The Velvia 50 film is available as 35mm, roll and sheet film .
