Auto profile matching problem with files from a minolta A1
Posted: Thu Nov 25, 2004 10:57 pm
I have build profiles from JPEG and "tiff trom raw" files. Whenever i use the profile matcher for a "tif from raw" file, a profile made from a jpeg file matches as long as one exists. When I only have profiles made from raw files, there is a correct match.
I could notice that compression level is not recognized in JPEG files from the Minolta A1. The information do not show when opening the image, neither do they when profiling. (shown neither in the profile name nor in the profile viewer info)
However, the compression info is correctly recognized from "TIF from RAW" files from the A1, (in the profile name and in the exif info textbox)
I had a look to the exif tags with exiftools
The A1 uses camara/imageCompression level only in TIF/RAW files. In JPG files, it uses the Image quality makernote with the following values
3 standard
2 fine
5 extra fine
1 uncompressed
If you need files, let me know and please give a mail.
BTW the noise reduction on the "tiff from raw" file seem to work **much** better than on the jpeg file, even at best quality. (maybe you could emphasize this if it is generally the case) I use minolta raw converter that has no noise reduction.
I use V4.0 on XP SP1.
Thank you for your help
