Film scanners are designed with the sole intention of scanning movies directly to your computer. Unlike their flat counterparts, they may be able to handle media sizes and thicknesses and can even scan the film if it has installed a transparency adapter, film scanners scan one thing: film. But because the scanned image is taken directly from the original material – the film, instead of a print film scanner, allows for more direct control of image elements such as cropping and d-aspect ratio. In addition, the film has more detail and a dynamic range compared to engraved – which invariably lose tonal range and color data during the printing process. These are real concerns for photographers and graphic designers, using slides and movies scanned and original films – to ensure the integrity of scanned images in professional and commercial applications. So if your work is based on digitizing negatives, slides and other films, a film scanner is the right choice for you. This buying guide covers some of the most important things you need to know when looking for a film scanner.
Style and Type
Some flat scanners include an external or built-in transparency adapter that can scan the film. Other flat beds are a double bed design; That is, with a bed – the flat part of the scanner glass – for the digitization of prints; And another bed – transparency bay that looks like a drawer slide – to scan the film. If you are going to analyze only the slide film or occasional interference, and do not bother the lowest resolution, a flatbed scanner that can accommodate a movie can serve its purpose. Keep in mind however, that film scannures that happen to not be suitable for commercial or professional use. To get the best results, nothing less than a dedicated film scanner will.
The bit depth of a scanner determines the number of bits captured per pixel, which is related to the number of possible colors. The higher the bit depth, the greater the number of colors can be represented. The bit depth for film scanners on the market today can be 30 bits, 36 bits, 42 bits or 48 bits. Always aim for more bit depth whenever possible, as this allows the scanner to work and maintain more amount of color information. A 48-bit scanner, for example, produces 65,536 levels or color tones per R, G, B (red, green, blue) channel, resulting in a possible combination of about 250 billion colors. By contrast, a 36-bit scanner produces 4,096 levels of information, less than 68.7 billion colors.
