Unfortunately, even when "Geotagging" is off, it is necessary to have
location services on to access the photo albums. This is a
requirement of the latest Apple software for accessing the photo
albums, and we have no choice in the matter. Apple's reasoning seems
to be that the photos on the camera roll may have location data
attached, so an app would be able to access the user's previous
locations. As the SDK is designed to provide full access to the
camera roll data, it cannot prevent an app from accessing any location
data that is present. Even if no photos have location data attached,
it would be too slow to examine the full contents of every photo and
video to verify this, so Apple has chosen to require location services
to access the photos. Apple's own apps, such as the Photos app, do
not have this restriction, but it is mandatory for apps from other
developers.
If that turns out not to be the issue, it could be that the resolution of your input photos was less than you thought. You could have lower resolution versions of photos on your iPhone/iPod/iPad if you downloaded the originals to your computer and then uploaded them back onto your device. (See next FAQ entry.)
You may also get lower resolution in some cases if there is much more than the usual degree of overlap between your photos, such as many photos of the same location. This may lead to excessive blur and a lower final resolution.
Some users make the mistake of equating file size with image size. Due to JPEG compression, a photo with a 2MB file size may have many more than 2 million pixels, depending on the contents of the image. You can check the resolution of any photo in AutoStitch. Tap Select Photos, select the single photo you wish to inspect, then press "View". The resolution will appear in the bar below the photo.
