Have been trying to do this for the last couple of days without much success i might add..Sad..Process followed:-

Set camera on Tripod
Set focus (havent got around to composition yet since this is an attempt to experiment the technique in itself)
Set camera to long exposure (15,20,25, 30) and narrow aperture
Create dark room effect
Paint object using an LED torch

Here's what iam getting

Of course needless to say iam not getting anywhere..info on the web seems sketchy at best..anyone with any experience or ideas on how to pull this off ??

You need to move the torch around much slower is my guess....!

Or maybe a wider aperture....!

Or maybe a higher ( more sensitive ISO )....!

Or maybe a brighter torch....!

Its one of those techniques that only experimentation will reveal, Because there are so many variables.....!

Not much help eh!

Thanks Vince..have tried the ISO will give the aperture and slow treatment a shot Smile failing which i guess ill keep experimenting as you say hopefully something will give....

Sorry, but are you trying to light it with torch, or are you trying to have light trail around it?

Did you point the torch towards the camera?

To have light trail, the torch needs to be pointed toward the camera.
What you were doing was just lighting the outline of your subject with torch, which is why the outline is brighter than the subject itself.

Correct me if I am wrong

The other factor is how far from the subject was the light. Remember light power observes the inverse square law.

So 2 meters away is 1/4 the light strength of 1 meter away . Three metres away is 1/9the power (ie 3 squared)

Did you just go around it once? Is this the sort of trail you're after?

Yep - just a case of not enough light (LED is deceivingly rubbish) and for not long enough.

I cant find my original at the min just this toy about with photoshop but the principal is the same.

Tripod...manual focus..about f8...and a shutter of a couple of seconds....iso 100......and the trick is a small Maglite with the reflector removed so you have just a bare bulb.

Yes i did initially but then tried continuous motion as well with mostly similar results.Yes something on those lines...

Would a mag lite do the trick ?


Quote: To have light trail, the torch needs to be pointed toward the camera.

Would that mean then that i need to be in front of the camera, with the object between me and the camera ?

Thanks Nick ill remember that

If you're trying to outline the frame, try with the base of the torch against the frame with the bulb towards the camera and slowly follow the edge of the frame around.
