Thanks Rephargotohp. I will. Went out a little while ago and tried to do some train blur. The train 5 feet away blurred but, obviously, as it got farther away or a train on the other tracks didn't blur. Kinda hard to do extended exposure in the daytime....still playing with the new camera.
I looked at your link. I am not sure, but believe you are on the right TRACK...I kill me!...with the second curtain idea. I'm not looking so much for the light streak with the train project. I would imagine if that had cars in tow, that they would be blurred in that example. That definitely could work with the auto project I spoke of very early...IF I time the shot right for the desired effect.
