Rotate an image's data 90 degrees. When a camera is facing ( and parallel with) the ground

I am using PowerApps to have employees take photos of incoming product.

We take all photos with our phones in EXIF-Horizontal orientation. Everything works great except when the mobile devices are taking photos in a horizontal orientation and are pointed straight down (phone is parallel to the ground). Most phones cannot determine the EXIF-orientation in this position and revert to the default vertical orientation.

The image capture for these photos are rotated -90 degrees. Screenshot below...

So in summary, the mobile device while pointing straight down loses it's EXIF-orientation so when I click the camera control, it captures the default EXIF-orientation of the device (vertical) and thus turning the image.

After capture, the upload button is clicked and the images is patched to a SQL server varbinary field. We then have to open the file on a desktop, rotate it in image viewer, then resave it to SQL.

Does anyone have any suggestions? I tried to use the image's image rotation property but that appears to only rotate in on screen and not change the image data. Thanks!

Hi @Andrew311 ,

The orientation of the picture itself when taken by the camera is in the control of the device, not Power Apps. The image will present (initially) as taken with the camera image top at the top of the image control. You can rotate the image (as below) as you have noted, but the underlying image cannot be modified in Power Apps to save in a different orientation.
