The shot with the zoomy lights was done by taking a long exposure on tripod - 10 seconds or so...and a zoom lens. ; Starting with the longer end of the lens (In my case I was using a 10-18mm lens, so I started at 18mm)...as soon as the exposure begins, slowly move the zoom ring back to the 10mm end...take about 2-3 seconds to do it. ; Then, the remainder of the exposure will be an 8 second shot fixed at 10mm...but the lights from the 18mm to 11mm zoom will have painted themselves onto the frame.
It's a silly effect - I've done it here or there - some photographers think it's a bit hokey - but I figure if you do it a few times a year, it can be fun and not too overbearing! ; For some reason, Christmas always makes me want to do a few.
Thanks guys!
