If the image that Autopano has automatically created is not level then you may use this function to fix it.

The panorama produced by autopano from your image set may have tonal aberrations and as such you may use the built in tone mapping features to correct this to start, use ‘Tone Mapping RH2’. This dialog enables the user to adjust luminosity through the Key value. You may play with that until you are satisfied or use the Levels as described below. Tone Mapping RH2 is actually more useful for high dynamic range (HDR). Adjusting Levels in autopano is similar to that of when adjusting levels in an image editing program such as Photoshop, Affinity Photo or GIMP.

Playing with the Gamma point level makes the image brighter or darker, whereas the black and white points of the histogram help make sure one achieves the tonal range required. Once completed, click the cog button and an options dialog shall appear. Here, you can choose to save your work in Photoshop’s native file format for ease of use their which shall keep all layers intact for fine tuning of your image. Using a dense dots per inch of 300 will enable you to print your work out. Play around with both the DPI and the scale factor as different values are best used for different use cases.

Autopano can project your panorama in many different ways: Little-Planet, Panini, Hammer, Mirror Ball, Orthographic and others. Choose the projection with a click and adjust your image with the Panorama Move option which will remap your projection on the fly, you will see a real-time preview final render. A classic 360° photosphere is created by choosing the cylindrical or spherical projection. If you have a panorama that includes architectural monuments, you might prefer to retain the rectilinear projection, which will preserve their straight lines. You can also create original panoramas with projections like Little-Planet or Mirror Ball.
