Sepiana 's weekly photo challenge (take two photos wide and zoomed in) reminded me of zooming on a subject during a long exposure. (I first did this on a Xmas-light-decorated church in about 1970 or so.) The town has a zillion LED lights in the Kinshelter park just down the street. So I went over this evening, set up the camera on a tripod and took a few 4-second exposures, zooming during the exposure. There is some shake. (The lights remind me of whippet 's recent post.)

I like this kind of abstract art, reminds me of string art, the sort done with little tacks and coloured strings.

These came out really good, Clive. I want to try this with my Christmas tree.

I want to try this with my Christmas tree. Give it a shot. My tree one was not great and binned it. First, I think 4 seconds was perhaps too long but try 2, 3 and 4 seconds. Just a hint that I did NOT follow.  So (say) you use a 2 or 3-second exposure (and appropriate low ISO and high f -stop), start zooming BEFORE opening the shutter. Here's why: the main source of shake will be starting the zoom ring. If you start the zoom first, that wiggle will not be captured. |

hmca Our tree ... the one I binned. I did play with levels a in ACR: increased exposure, reduce whites and brights, lightened shadows. WB was also tricky .. use AWB but then I fiddled with this in ACR a couple of times. Jazzed up overall saturation and then reduce yellows. The red and green in upper right are actually our neighbour's house lights. Have fun. Explain this to me: Our tree only has white LEDs, yet they come out different colors. It might be a 60-cycle thing.

pontiac1940 ......what's that saying "One man's trash is another man's treasure."? I'll be quite pleased if mine comes out that good.

Nice Judy....looks like well placed ornaments!
I played with this a bit but not happy enough to post any yet. Will keep trying.

Good try Helen. If the zoom mechanism is a tad sticky or not smooth, it is hard to zoom with no shake.
However, your result is still pleasing. Thanks for giving it a try.
