The Windows Picture and Fax Viewer (XP) and Windows Photo Viewer (Win7) fall into the latter category.

Other software takes the data from the X and Y axes, physically remaps it all to the new orientation, and re-saves the image with additional unwanted JPG compression. Some software does a 'lossless rotation' by only changing the value of the EXIF tag so that the software now does a virtual rotation to display it that way again. The user can end up with incremental errors if they think an image is wrongly oriented when seeing it in an application that disregards the tag, and they then decide to rotate it. Part of their logic does make sense where users have one piece of software that supports it and one that doesn't. They have explained their reasoning for non-support under the 'More Information' section here: Because these are part of Windows Explorer, Windows itself completely ignores the orientation tag. Supporting software should read the value and display the image in the orientation that it was originally taken so that it displays as the photographer intended it to be viewed.īecause there was such a mish-mash of support, partial support, erroneous support, and non-support for the EXIF Orientation tag value, Microsoft decided not to include support for it in their in-built Windows Picture and Fax Viewer (XP) and Windows Photo Viewer (Win7). (I hope I got these correct - I was sitting and doing various contortions with my head to visualise it). on the vertical axis - mirrored).ħ - Same as 8, but horizontally flipped (ie. on the vertical axis - mirrored).ĥ - Same as 6, but horizontally flipped (ie. on the vertical axis - mirrored).Ĥ - Same as 3, but horizontally flipped (ie. If ever seen as a value, perhaps after an image editor did some lossless processing and modified the Orientation tag, the following values would have the respective meanings:Ģ - Same as 1, but horizontally flipped (ie.

The common values for the Orientation tag tell supporting software that the camera was held as follows when the photo was taken:Ġ = Camera doesn't have an orientation sensor or the feature was disabledġ = Horizontal/Landscape and upright - normal position.ģ = Horizontal/Landscape but held upside down.Ħ = Vertical/Portrait - Turned clockwise by 90 degrees from normal upright position.Ĩ = Vertical/Portrait - Turned anti-clockwise by 90 degrees from normal upright position. I doubt whether a digital camera would flip an image before saving it to the camera's memory, unless it has some cheesey special effects options that might do this.

It would be very unusual to see values of 2, 4, 5, or 7 against this tag, because they are only used where an image is flipped horizontally (mirror image) and presumably would only be written to the image by software that respects and fully supports all the available Orientation values. They write a 0, 1, 3, 6, or 8 value to the EXIF metadata tag named 'Orientation'. Most modern digital cameras now have an orientation sensor that detects how the camera was held in relation to the ground.

I realise this question is in the process of closing, but I thought I would add some details to try and explain the inconsistencies between Windows, browsers, and image viewing and editing applications.
