Not just light painting... anyone tried Parabolas?

Focus should be the easy part (used to focusing in the dark), but how do you go about swinging it? Getting an LED on the end of a piece of string?

Fstop, please tell me how you did yours, I'm racking my brains trying to figure it out .

lol

multipue L.E.Ds mate.

Measure the distance between the front of the lens and the hanging object. Set the camera focus based on another object placed at the same distance and then set the camera to manual focus. Easy.

Just tried some of these, I'll upload soon

benjo · 30 Sep 2009 at 21:02

I've cropped some of them because I think they looked better...

Love the 4th down benjo.

Thanks

Something a bit different?

benneh · 1 Oct 2009 at 22:57

Makes me wonder, why is it that the effect and trace of the light, the shadows, the immitation of catchlights and so on, looks exactly like it would if there were a single constant light source, like Mark A's last image, it looks basically as it would have had there been a central light source, rather than a moving, slowly layering 'light'. How very odd, 'mazin.

1st attempt. Pretty much straight off camera no tweaking.

these are brilliant, but would i be able to do it with my camera? i clicked it to manual mode but it only allows me to do 30seconds max, it doest have full bulb mode.

You should be able to have a reasonable attempt, I've managed OK with 30s bulb exposures. What you won't be able to do is get a really long trail like Nutster's second one.

Speaking of which, Nutster is that second one just a really long (as in time) eliptical swing? I can't work out how you got the spiral arm look...

adbp1 · 5 Oct 2009 at 15:45

cool, jsut need to find decent led light, and black out my room !!

I really quite like the effect I managed. They're both the same light, just one is a lot longer exposure. The EXIF's are in those pics.

I love the fact that the ligh intensity is different around the image, giving graduations along the lines, and a bit of depth. I think this was due to the light I was using.

It was an LED pen, that I took the front nib part off. The LED was receded back inside the cylindrical case, so as it swung at different angles, more or less of the blue LED was visible, which gave my light trails their varying look.

Hope that makes sense. I'm gonna try a few more techniques next weekend.

Is it not a multi-led torch then? I cant get my head around how you get the criss cross effect. Looks similar to Fstop11s but he said he used multiple leds.

Some of these would make great desktop images.

Nutster · 5 Oct 2009 at 23:24

Heres a picture of it.. I had it suspended from the button on the end. The insides metal and reflects the light differently depending on the angle it hangs.

Heres a link to 1920 landscape version of the 1st one.

I may give his a try at the weekend, I have an idea or two but I'll have to pick up a remote release and find a few LED lights first
