I do not have your equipment and never will. I'm a point and shoot type but now only have a cell phone. But I really appreciate the tips about processing. I have that orange light a lot and now I can fix it.
I was looking through the photos before reading the text and wondered about you. Thank you for showing us your fails. This is so helpful for my eyes to see.
I take a lot of light trail type photos as I am often out at night. But my way of doing this is by moving the camera. Sometimes the subject stays in focus and the lights jump. Other times it is all a colorful blur. But I get nothing like your pretty fairy tale shots. They look like you are in another world.
