One fine day, bored at home, I tried this. Just my small tripod, my old PowerShot s60 and a small Maglight. I went to my room, with all the shutters down; I set the shutter speed to 15" and I used the spotlight as a flash as i changed my position. Not a good photo as itself, but good as a test for me. NO PHOTOSHOP. (well, just to crop the picture).
Hey Ferran that is really cool. Your right for a test. Give lots of thoughts to new ideas and some great photos. May have to do some testing on my own.
i think the result is nice. u can just check the cordinates of ur frame in ur mind and consider where to pose and for how long. i guess u r gonna need someone to do so. u can end up with some wonderfull results. very well done. i like it alot. i love long exposures.
