Clockwise from top left: uncorrected, high, medium and low grain correction.ġ00% crops from SilverFast. Each program was operating at its defaults other than the grain correction.ġ00% crops from Epson Scan.
The 100% crops below come from this overall scene. All three programs allow a three-step control over grain reduction strength. This was in part because each app's varying tone curves and sharpening tended to emphasize grain differently in the first place, and also because I mostly tended to shoot only film at ISO 800 or below. When we pointed out weaknesses in their drivers, the manufacturers assured us that they would remedy the weaknesses quickly.Grain reduction was tricky to judge. However, it is gratifying that all manufacturers contacted by Linux (Pro) Magazine have adapted their Linux support to reflect the real world. Only then can it be assumed that the available Linux drivers cover all functions required in everyday life. It is still the case that brand new appliances on the market generally still need a few weeks to mature. Scanners may only work in groupware solutions under Linux, or they may only provide support for certain interfaces such as Ethernet. These devices often support Linux, but only in certain application scenarios. Before purchasing a multifunction device or scanner, it makes sense to put large devices in particular through a functional test and carefully read the technical specifications. Nevertheless, some stumbling blocks still await you. For this reason, most front ends, but also drivers developed by the manufacturer, integrate into the Linux ecosystem. SANE has established itself as a back end for controlling the devices. The availability of Linux drivers for scanners and multifunction devices under Linux is far better today than it used to be.
