Inside the box I have a white panel that I can move back and forth to get the focus ( the box can be slightly open on top so I can see ). Then I put a small digital camera in the hole beneath the "lens" that can capture the projection on the panel inside. I was so curious about how the depth of field world be with a large lens and a large projection.
Hard to focus on a white card. I still think he focuses on the real image (which, although I didn't mention it, is formed on the white card).
I think the magnifying glass is used as the objective lens of the "big camera". Then the digital camera focuses on the image generated on the white screen by that main objective lens.Yes, I focus on the projection on the white card.
//Asher Kelman - So you have done the same thing, but without a magnifying glass? Cool.
Wonderful results. They may be fuzzy, but they work. I see you are a musician also. What kind of music do you make?... lens, does not result in good quality but very fun to make and investigate =) The thought was to make a large format cardborad box and to be able to shoot the projection inside it with a digital camera so I can view the result directly.
Where is he alone with the guitar and some of the recordings you invented seem to have no vocals?I did many styles but my main passion is blues. At one time I did sounds and demos for an american company called Ensoniq, that made synths and samplers. And as I do strange things with photography I also did with music. For instance extracting Lightning Hopkins voice from a record and put his voice on a new arrangement that I made ( like using blue screen =) ). Delta blues artist Lightnin' normally plays alone with his guitar and I wanted to hear him in a Ray Charles like arrangement http://www.lutzimages.com/mp3/lightnin.mp3
