    Maria prabhudoss Community Member

      I have saw some differences(rotation) while opening the same image in the photoshop and imaging preview applications. imagerotate.GIFKindly advise me, why this difference occurs. I have attached the screen shot for your references.

          I guess the file contains an orientation tag that instructs the displaying app to rotate the image, and Photoshop is obeying that but your other apps are not.

            Thanks for your immediate response.

             

            Other application name is "Imaging for Windows preview" And "*Microsoft

            office picture manager*". Am using other application for to view that

            image.

             

            But if i Saveas, that same image and open it in above mentioned "image

            preview" application, its shows an correct view.

             

            Please advise me.

                If conroy’s surmise is right that is to be expected.

                Photoshop honors the metadata and rotates the image, when »Save As« is invoked the rotated image is saved.

                  Thank you. I am having one more question. Why this differences occurs only in very very few images?

                  Most of the images showing a very correct view in both "photoshop" as well as "image preview" applications. Could you please advise me.

                      Conroy gave you the most likely correct answer possible in post #1.

                        what is your capture device?

                        See if this info helps or applies to your setup:

                        http://www.impulseadventure.com/photo/exif-orientation.html

                         

                        some interesting tidbits from the above site:

                        Windows Picture and Fax Viewer

                        Surprisingly, the Windows Picture and Fax Viewer (built into Windows XP) and Windows Photo Viewer (built into Windows 7) do not support the EXIF orientation flag. This is surprising, as the makers have obviously thought enough to support lossless rotation functions. So, what you will see shown by the viewer is the real image data (assuming landscape orientation), without respecting any indication from the camera as to the real orientation of the image.

                        Beware of Rotating Photos in Windows Picture / Photo Viewer!

                        Another surprising detail is that if you decide to perform lossless image rotation (by using the Rotate Clockwise or Rotate CounterClockwise buttons), the EXIF Orientation flag is removed! As the flag is removed/reset, if you do a rotation followed by its reverse rotation on a portrait photo (eg. rotate clockwise, then rotate counter-clockwise), the resulting orientation observed by other viewers such as Photoshop will be wrong!

                        In fact, when you use the rotate functions of Windows Picutre Viewer, most of the image metadata (camera information, shot details, makernotes, etc.) are deleted. Therefore, I strongly recommend against using this program to rotate any of your digital photos.

                          Thanks charles. capture device of that image file is "Canon DIGITAL IXUS 850".

                            A point and shoot? Yes, that will place camera orientation metadata in the image file. Keep the camera oriented the same for all photos. As far as your existing pictures... I'm not sure if a Save As in Photoshop (creating in a duplicate file with a diferent name) will erase the orientation marker. I'm sure Save For Web would, but you may not want to do that, especially if these are large files.
