What causes camera lens distortion?
How to calibrate your lens.
The calibration process involves taking a series of photos in a controlled way, so you can see exactly how your focus is off.
You can then correct it using your camera settings.How do you handle distortion in camera calibration?
Barrel distortion often occurs when using wide-angle lenses.
This is because the field of view of wide-angle lenses is wider than the image sensor on a digital camera and therefore the image looks like it has been squeezed and constricted to fit in the edges of the frame.
