Classic B&W Film Simulation from Fujifilm
Acros is a brandname for an ISO 100 speed orthopanchromatic black-and-white photographic film produced by the Japanese company Fujifilm. As of July 2012, the film is available in 135 and 120 roll film and 4x5 sheet film formats. Acros, as with most other films of its speed, is optimized for high sharpness and fine grain. The film is suited for night and long exposure photography due to its reciprocity characteristics: it does not require adjustments for exposures shorter than 120 seconds, and only requires a ½ stop of compensation for exposures between 120 and 1000 seconds.
It has been over 10 years since the introduction of Film Simulation. Its history began with the model FinePix F700 back in 2003. The monochrome was called "B&W" back then, and the image quality it produced was highly regarded. At the same time, a question was thrown, "Which film is the B&W simulating?" The answer to the question is, "B&W" is based on PROVIA, and it is not based on Monochrome film. This fact also reflected the sentiment of the Image Design team at FUJIFILM, that "It is too early to name a simulation mode after any monochrome films, which are all legendary." So now Fuji have a film simulation mode named after monochrome film. In order to have "ACROS" mode, it had to meet certain standard.
What does it take to be "ACROS"? What kind of monochrome expression does it need to have? First, it needed to be capable of expressing details like the ACROS film, which was often praised as "world's finest grain" Secondly, it needed to achieve print-like texture, like how a photo would appear when taken by a monochrome film and printed on a photographic paper. In order to become the digital "ACROS", the mode needed to achieve both subject's
The tonality curve becomes rather soft, unlike the hard tonality curve from the middle to the highest. It means that we do not lose the detail as much as possible on the shadow range. The essence of monochrome expression exists in the shadow area. If it is too soft, then the image becomes too loose, and if it becomes too hard, then the picture loses its depth. The optimal balance in the shadow area determines the quality of the monochrome
In the low light area, you would see the graininess just like how it would appear with the monochrome film. There are undulating grain within the picture. And it adds depth like no other.
Neopan is a contrasty, high res B&W film, with rich blacks, vibrant whites and very nice tonal range. Contrary to what some other companies call "film simulations", Fuji takes great care to replicate the particular characteristics of each film they reproduce, going much further than a simple saturation/contrast curve, but keep something in mind: the film simulations are digital analogs, which means they are customized for a digital's camera response (X-Trans, in particular)
"Acros" is different
"When you photograph people in color, you photograph their clothes. But when you photograph people in B&W, you photograph their souls."
