1. A method for electrospinning of material by ejecting spinning material from a nozzle outlet of an electrospinning apparatus, the nozzle outlet having an outer diameter, the method comprising
determining a shape of a conus of fluid spinning material exiting the nozzle outlet from an image captured during operational use of the electrospinning apparatus, wherein determining a shape of the conus comprises a calibration of the captured image using predetermined dimensions of a reference part of the electrospinning apparatus and edge detection in the captured image,
determining from the shape of the conus a spin wire diameter determination area in the captured image,
detecting an actual spin wire diameter at the spin wire diameter determination area, and
controlling operating parameters of the electrospinning apparatus based on a difference between the actual spin wire diameter and a desired spin wire diameter.
