According to IMAGING RESOURCE the Canon PowerShot A560 used for this picture has a Barrel Distortion on the wideangle setting of 35 mm (35 mm equivalent) of 0,8%.
This distortion is corrected in the picture above with Adobe LightRoom setting +8 for Lens Correction. I checked whether this LightRoom setting cancels the barel distortion correctly by applying it on the the published Test-picture.
Due to the image correction and change in format of 1:1.33 to 1:1.5 the focal length is now corresponding to about 38 mm.
I couldn't find an altitude measure for this picture but similar pictures taken from similar balloons of Robert Harrison are stated as between 30 km and 35 km altitude.
According to cnet.com the PowerShot A560 has a zoom range of 5,8 mm to 23,2 mm, which corresponds a 35 mm equivalent of 35 mm to 140 mm.
