Light painting - revisited

@Babul Bhatt: all you need is a light source and a really really dark room with no stray lights as u dont want any midtones as i have mentioned above....the more creative the light source is, the much better the texture will look...like in this case i used a green 9 LED flash lamp and tht gave it the thread like texture....just shine the bright light at any angle(other than 90degrees) to the lens plane and try to iteratively decide a good shutter speed for the exposure...maximize ur dof also as u r only goin to be a feet or 2 in front of your lens....also make sure the area behind the light source is black...may be a cloth blanket......set the contrast in ur camera to max...there r a few other things tht you may improvise on the fly when u do a low light capture...finally invert it
have fun
