![]() Using the normal curve dialog in SilverFast, I was able to obtain good detail and tonal representation in all the levels of this negative. Here is a scan of a shot made with a C-41 process chromogenic black-and-white film. In the Frame pane, the size of the original and the size of the image output and its resolution should be set for a final scan. You can then select whether you want to output a file within an application like Photoshop. In the lower part of the General pane you input the kind of scan, whether a positive or a negative, as well as a selection for Kodachrome, providing either an IT8 profile adjustment for Kodachrome film or an interpolated one based on the scanner’s E-6 film profile. So finally, I am happy with the result after half a lifetime.īelow is a two-pane General and Frame dialog that provides support to select the kind of output, and if used for a finished file, to select the kind of and degree of filtration or sharpening. But this and similar shots have always scanned very grainy, but the CanoScan 9000F did not reproduce the usual rough-looking image. This film was about as grainy as any ever made, and I often used it with a soft-focus lens to make portraits. This function is optional and can be selected in the SilverFast preferences' general tab.At least 40 years ago I was shooting a very high-speed Anscochrome film of patterns in a lake surface with a very long lens. While normal HDR(i) files store their changes in a local database. HDR(i) RAW files store all changes and settings inside the image file. Following this way, various image optimizations can be made from the same starting point for comparison. Optimized images are exported as TIFF or DNG files, while retaining the original image data. In addition to the image data, color management information is included, where applicable also infrared data for dust and scratch removal and Negafix profiles for negatives. ![]() ![]() The HDR(i) RAW files can be considered as a kind of "RAW format from analog data". Xx Bit HDR(i)RAW advanced High Dynamic Range Archive format information This is the most common Archive Suite format for grayscale film processed using the C41 standard (like color film). This format does save the infrared channel. These are saved unaltered and are optimized for processing in SilverFast HDR (Studio). This creates 32 bit raw grayscale archive images. This is the most common format for images used in the Archive Suite workflow.ģ2 Bit HDRiRAW High Dynamic Range Archive for Grayscale Images with Infrared Channel This format does save the infrared channel for iSRD processing. This creates 64 bit raw color archive images. This is the most common Archive Suite format for grayscale silver halide film.Ħ4 Bit HDRiRAW High Dynamic Range Archive for Color Images with Infrared Channel This format does not save the infrared channel. This creates 16 bit raw grayscale archive images. This format does not save the infrared channel.ġ6 Bit HDRRAW High Dynamic Range Archive for Grayscale Images This creates 48 bit raw color archive images. Simple JPEG files can not store 16 bit data (see 16 -> 8 bit).Ĥ8 Bit HDRRAW High Dynamic Range Archive for Color Images Simple JPEG files can not store 48 bit data (see 48 -> 24 bit).ġ6 Bit High Dynamic Range Grayscale Imagesġ6 bit grayscale images are best for further editing in professional software like SilverFast HDR (Studio) or Photoshop. This for example can be used for scanning text.Ĥ8 bit color images are best for further editing in professional software like SilverFast HDR (Studio) or Photoshop. This creates 1 bit images which only consists of absolute black and white values. 8 bit data can be saved into small JPEG files. When you do not know which output you should use for grayscale images, this is most likely the right one. 8 bit is the most commonly used grayscale depth for most applications. ![]() 24 bit data can be saved into small JPEG files. When you do not know which output you should use this is most likely the right one. 24 bit is the most commonly used color depth for most applications. This creates the usual 24 bit color images. SilverFast offers different bit-depth possibilities.
