REcognition of Image Rotation Information Stored in JPEG
I have recently purchased a Canon EOS 10D digital SLR. This camera stores image orientation information in the JPEG files. The Canon software in the camera and Photoshop 7.0 (File Browser) both recognize this image orientation information and correclty display the image on screen. However, I was disapointed to see that Sivlerfast DC PRo (version 6.1.0r3) does not apparently recognize the oreinetation data in the file since images must still be manually rotated within the Silverfast software. Furthermore, it does not appear to be possible to rotate the images within the Overview. Until the image is moved to an Album it cannot be rotated. This makes working with images in DC Pro-VLT more difficult than in Photoshop 7.0's File Browser.
My qusestions are: (1) Am I not doing something correclty to have Silverfast display the images with the correct orientation; (2) If this capability has not yet been included in the Silverfast DC Pro software, are there any plans to do so?
Thank you in advance for a response.

Recognition of Image Rotation Information Stored In JPEG
Eric,
Thanks for letting me know this. I look forward to seeing this in a future update of DC Pro.

The auto rotation of images is implemented now and will be released in version 610t5 if it passes our testing.

Eric,
I have been watching the update section of Silverfast ever since you posted the above e-mail, but I have still not seen version 6.10t5 posted as of today's date (October 16th). Do you have any idea when this might be posted? I am processing lots of Canon EOS 10D images in Siverfast and having the oreintation information generated by the EOS 10D recognized by Silverfast would certainly speed up my work flow.
Thanks in advance for your response.

Version 610t5 was frozen two days ago and testing began immediately. The auto rotation feature was already tested positiv. I would expect a release version of 610r5 coming up in the middle of next week.
Eric.
I downloaded the release version of r05 for mac OSX last night. On the version I have auto rotation is not functioning.
I also note some other issues:
1. The transition period between VLT window disappearing (conversion complete) and the SF preview window reappearaing is VERY long (unacceptably long).
2. When the SF preview windows eventually reappears the Special Function buttons are disabled.
I've gone back to r04

I just downloaded and installed the 610r5 version of Silverfast DC Pro for Windows, and it works beautifully. I notice that it even puts the file names in red of those images that have been automatically rotated in the Overview Window. These are 3-4 MB images and when I click on full screen preview, it opens in about 2 seconds. No complaints here on Windows about this version. Thanks very very much to the Sivlerfast team for including the recognition of image rotation information so quickly in Silverfast DC Pro. You guys do a terrific job with this software and I am pleased to continue to upgrade eery time a new version is released.

Tom,
Sure I get vertical previews for all about 2 seconds and the damn things turn back to horizontal as DCPro reads the data. Every time VLT opens it regenerates the thumbnail previews.
From your description I get the impression you are referring to JPEG images or else the Mac version is screwed. DCPro was DESIGNED to help those of us using RAW images. I can tell you that R05 does not auto rotate RAW images on the Mac platform and until it does then it will languish in the also ran dept.
I have trashed preferences, etc (including those newly generated prefs that placed in the users Home folder).

Ian,
Yes, the images that I just finished examining in DC Pro were the highest quality (least compressed) JPEG's that my Canon EOS 10D can produced. I do have some raw Canon EOS10D images that I can test Silverfast DC Pro with and I'll do so and post the results. (These RAW images have been saved off to a data DVD and I'll have to locate them.) I am not seeing the behavior that you describe in VLT. Thus once my thumbnails were generated after installing DC Pro, they appear instantly (less than one second) after opening DC Pro. My vertically rotated images are also not returning to horizontal images. Again, I'll give a try when i get time with RAW image format, but at least with these Canon JPEG files, DC Pro on Windows is behaving exactly as expected.

I can now verify that the latest version of DCPro (610r5) does NOT rotate Canon EOS 10D RAW image format files. These RAW image files do appear in the Overview Window when a folder containing them is selected in the Navigator (which is more than I can say for Photoshop 7.0 where the RAW image files do not even appear in the File Browser view) but vertical RAW image files are not rotated. A full screen preview image takes about 7-10 seconds to appear on my screen (1.8 GHZ pentium 4 with 1 GB of RAM) which does not appear to be an excessive amount of time. I have no problems with vertical images, although not rotated, disappearing a few seconds after selecting them.
