Thanks for comments all becoming a bit of a panning addict need to try some different shots but i just love pan shots at low shutter speeds really gives life to the picture with lots of movement.
Pics shot using my Canon 450D with a Canon 55-250IS Lens
I have now added the details above each pic.
They were shot in shutter priority where i selected the shutter speeds i wanted and played around with ISO settings and the camera did the rest i did a few at the end of the day in manual.
The shots at lower focal length were cropped as sometimes i find i can zoom in closer but it can result in a great pic that is just to tightly framed i prefer to give myself room to crop out unwanted objects like wheelie beens and place the car so it has space to run into.
