Wow, very interesting result! It would be interesting if you could explain how you did this ?
I like it
With pleasure!
1. I have mounted a small child puzzle, I have painted it in black with an indelible marker. I have separated the pieces to make with the white background - 100% - another empty puzzle pattern. I have traced the edges of that same final pattern on a transparent paper (to carry with me at all times).
2. I have inserted a T-max roll into the camera and with the initial "loading" posture I make a mark before closing the camera back cover (this camera model has an automatic film transport). I have exposed the whole roll for the first time with the same texture with the Cosina lens, which will be the secondary subject (puzzle), - the black will be white and also the part that I'll need to fill again in the second exposure -. Hand-held, without focusing ... until the end of the roll.
3. When the roll & rewind are finished, I have removed the leader from the cartridge, and again I loaded the roll ensuring the same mark in the same exposure to superimpose frames as accurately as possible in the second automatic transport (just a couple of millimeters unbalanced...) Camera, special T-max and transparent paper ready in my backpack ... That's all!
Pathzzle: (Path + puzzle) With this photograph, I wanted to obtain a line path: a) with the main subjet of the floor in the second drawing and b) with the white silhouette (due to the separation heads of the pieces) with the most open floor tiles on the right and the closed ones vanishing on the upper left. Note: There is a small seed and its shadow on the ground - in the second lower right piece - "as you can see it didn't fit perfectly where I wanted to", despite the help with the transparence paper, the possible calibration failure and the experience I have in these random bids.
I have made these kind of experiments with very different patterns as first subjet, and/or including masks and/or using more than two exposures. Your imagination is the limit.
Thank you!
