A new experience of photo for me:  2 combined technics:
The zoom out I use for several years to give speed feeling, combined here with a speed motion trail effect at the same time.
Many tries and many bad results to obtain a photo able to be showed.

This photo is taken thru the fence, after the Combes corner, on Spa circuit.
This car is the Aston Martin Vantage GT3 #97, Team Oman and TF Sport) at 24 Heures of Spa 2019.
