Why Are My Google Video Uploads Turned Sideways?
E'er wonder why some photos look right in some programs, but appear sideways or upside downwards in others? That's considering there are two different ways a photo tin can be rotated, and non every program is on the same page.
The Two Means an Image Can Be Rotated
Traditionally, computers have e'er rotated images by moving the actual pixels in the image. Digital cameras didn't bother rotating images automatically. So, even if you used a camera and held information technology vertically to accept a photo in portrait way, that photo would be saved sideways, in landscape fashion. Yous could then employ an image editor program to rotate the image to appear in its correct portrait orientation. The paradigm editor would move the pixels to rotate the prototype, modifying the actual image data.
This just worked, everywhere. The rotated epitome would announced the same in every plan…as long as you lot took the fourth dimension to manually rotate them all.
Manufacturers wanted to solve this annoyance, and then they added rotation sensors to modern digital cameras and smartphones. The sensor detects which way you're holding the camera, in an endeavor to rotate the photos properly. If yous accept an prototype in portrait manner, the camera knows and tin deed accordingly then you don't have to rotate information technology yourself.
RELATED: What Is EXIF Data, and How Can I Remove It From My Photos?
Unfortunately, at that place's a pocket-sized caveat. Digital photographic camera hardware just couldn't handle saving the epitome directly in rotated form. So rather than performing the computationally intensive chore of rotating the unabridged image, the camera would add a modest piece of data to the file, noting which orientation the image should exist in. It adds this information to the Exif data that all photos have (which includes the model of camera you took it with, the orientation, and possibly even the GPS location where the photograph was taken).
In theory, then, y'all could open that photo with an application, it would look at the Exif tags, and then present the photo in the right rotation to you. The image data is saved in its original, unrotated form, but the Exif tag allows applications to right it.
Not Every Program Is On the Aforementioned Folio
Unfortunately, not every piece of software obeys this Exif tag. Some programs–especially older image programs–will just load the image and ignore the Exif Orientation tag, displaying the image in its original, unrotated state. Newer programs that obey Exif tags will show the image with its right rotation, and then an image may appear to take different rotations in dissimilar applications.
Rotating the image doesn't exactly help, either. Change it in an old application that doesn't sympathize the Orientation tag and the application volition move the bodily pixels around in the image, giving it a new rotation. It'll look correct in older applications. Open that epitome in a new application that obeys the Orientation tag and the application volition obey the Orientation tag and flip the already rotated image around, then it'll expect wrong in those new applications.
Fifty-fifty in a new application that understands the Orientation tags, information technology's often non quite clear whether rotating an image volition move the actual pixels in the image or simply modify the Exif tags. Some applications offer an option that volition ignore the Exif Orientation tag, allowing you to rotate them without the tags getting in the mode.
This problem can occur in practically whatever software, from a plan on your PC to a website or a mobile app. Photos may announced correctly on your computer but appear in the incorrect rotation when y'all upload them to a website. Photos may appear correctly on your phone just incorrectly when you transfer them to your PC.
For example, on Windows 7, Windows Photo Viewer and Windows Explorer ignore the Exif Orientation tag. Windows eight added back up for the Exif Orientation tag, which continued into Windows 10. Images may announced correct on a Windows 10 or 8 PC, but rotated differently on a Windows seven PC.
New Software Nearly Always Obeys Exif Orientation Tags
Thankfully, most applications now do obey the Exif Orientation tag. If y'all're using Windows 10, File Explorer and the default paradigm viewer volition properly obey the Exif Orientation tag, and so photos that come from your smartphone or digital camera will exist display properly. Google's Android and Apple's iOS both natively create photos with the Exif Orientation tag and back up it.
If you lot're using Windows seven, yous tin make this trouble become abroad by upgrading to Windows ten. If you'd like to keep using Windows 7, you may want to apply another image viewer that obeys the Exif tags instead of the default image viewer.
The average website or desktop application should besides obey Exif Orientation, although non all of them do. If a photo appears sideways when uploaded to a website, that website needs to be fixed–merely you can probably rotate that image on that website anyway. Desktop tools for working with photos should as well support Exif Orientation tags. If an application you use doesn't, you lot may want to find a more modern awarding.
How to Fix Image Rotation for Older Programs
If this is a problem for yous–peculiarly on Windows vii–you can also use JPEG Autorotate, which uses the jhead command in the background. This tool adds a quick right-click "Autorotate all JPEGs in folder" option to Windows Explorer. Select it and the tool will examine all photos in a binder, automatically rotating them according to their Exif Orientation tags and then removing those tags. Use this tool when you lot import images and Windows 7 and other applications won't accept a problem with them.
Modern smartphones and digital cameras take faster hardware, so it should be possible for them to salvage photos in an already-rotated land instead of just applying the Exif Orientation tag. Unfortunately, the industry seems to accept settled in Exif Orientation tags as the standard solution, fifty-fifty if they aren't platonic.
