Autopano - Supported file format in input

Supported files formats

Autopano supports most image file formats:

The Grayscale color mode is not supported.

  • JPEG : No particular comment on this file format.
  • TIFF : 8 or 16bits.
  • PNG : 8 or 16bits.
  • RAW : The generic term RAW refers to "raw sensor" image formats of each brand of camera devices (or models of a brand) eg NEF for Nikon, CRW or CR2 for Canon... etc.
Note : See the FAQ: Can Autopano stitch RAW files?
  • DNG : The Digital Negative format from Adobe allowing to store any raw file in a unified RAW format.
  • HDR : The Radiance format is supported and allows you to stitch HDR panoramas from HDR source images.

EXIF data

The "EXIF data" correspond to the shooting settings. Autopano uses these data to find several information:

  • The lens type used

There is 2 Lens types available, Fisheye and Standard. The limit value between them is 15mm:

- if the focal length is below 15mm (or equal), the Lens type is set to Fisheye
- if the focal length is over 15mm, the Lens type is set to Standard

Basically, Autopano sets the Lens type depending on Lens ID (calculated with the makernotes) insofar the file format includes maker notes (this is the case with RAW files).
Any image processed through a third party software looses its makernotes. So Autopano can't set properly the Lens type and can give wrong information (this case requires to check the setting and to modify it if necessary on the Image Properties).

  • The lens focal length used

Autopano bases all his calculations as 35mm equivalent. To calculate the 35mm equivalent (focal length stored in the EXIF data), it is necessary to know the ratio between the sensor's size used and the 35mm sized sensor.
Autopano therefore contains a database (cameras.txt file) including the ratios of each camera model to obtain the Camera sensor scalling to calculate the 35mm equivalent.
If no EXIF is included, Autopano uses default value ​​corresponding to a "standard" lens (50mm in 24x36 format), i.e. the value defined on the Preferences, Images tab.

  • Shutter speed and aperture used

These two bits of information are mandatory to create HDR panoramas. If the images don't contain these data, the HDR color correction can't be enabled in the panorama editor.

Further information are used as the shooting date and time to sort the source images in groups, or as the ISO value (even if it is not used yet, it is an interesting information).
All this information are visible in the Shooting information of each image group created in Autopano.

If Autopano doesn't find the EXIF data while these information exist in the image file; that means that the camera model is not yet included in the cameras.txt database.
In this case, keep us informed of this lack to update the database and allow the support of your camera in the software.
