The image below is the waterfall negative scanned using Silverfast HDR mode. Instead of driving the scanner directly, SilverFast HDR enables the user to read these raw files and.
Since the file content appears to be modified during the DNG conversion, I would prefer to stick with the original DNG images in my archive. Vuescan and Epson Twain both produce 48 bit files, whereas Silverfast only. 48 bit files retain all of the information supplied. Also, Adobe DNG converter reduces the file size to about 50% of the original (despite using a non-compressed setting). However, when I developed the converted, PM readable files I noticed that the color information must have been changed during the conversion process and the color rendering comes out quite differently in my raw developer. When manually processing the Silverfast DNG files with Adobe DNG converter, PM can read the files. In HDR, all SilverFast tools are available: Defining Output Size & Resolution, Auto-Adjust of Highlight/Shadow, Three Part Histogram, Gradation Curves, Selective Color Correction, Unsharp Masking, Color Cast Removal Slider, Color Separation, CMYK-Preview and more.
SILVERFAST HDR 48BIT RAW FILE 64 BIT
I enabled Raw Rendering with Adobe DNG Converter, but when trying to use Tools/Raw-to-DNG I get an error message that no raw files are available. SilverFast HDR enables the user to read and process 48 bit (or 64 bit HDRi) RAW files without being connected to a scanner. Also, trying to add IPTC information to the files results in an error message. Interestingly, in cases where I created the corresponding JPEG file in the same folder, PM does not render the JPEG either, although it recognizes the JPEG's presence by showing 'filename.png+jpg' below the thumbnail. When opening in the Preview window, it shows 'Unsupported Format Variant' instead of the preview. In PM (Build 5820) the thumbnail displays are empty and the filenames are shown in red. the full Dynamic Range (HDR - High Dynamic Range) of the hardware in TIFF data files.
This file stores the raw output of the scanner, and minimal adjustment is made at. scan your images easily into 64bit/ 48bit HDR(i) RAW data format. Mylio and Affinity Photo can read and display these files without a problem. One first makes a 48 Bit HDR Colour scan using the scanning software. I started using the HDR raw DNG file format (48-bit) to archive negative scans coming out of Silverfast.
