This is a no-cost way to get into macro photography. You only need a string, little tape, used up glasses, and a tripod. If you like to make surprising experiments with your analog darling, you've got to try it out!
You may use almost any camera for this! It’s only necessary to get the back opened (so e.g. no instant cam). Medium format is advantageous, because its easier to focus, so I took my Zeiss Ikonta.
Here’s how to practice the technique:
Just look for a simple eyeglass lens and tape it in front of the camera lens (my one was very old and completely scratched). Then, you need a matt screen: it’s easy to make one using a carton of cardboard box and parchment paper.
Screw the prepared camera on a tripod and search for something with high contrast and bright colour (I used yellow gloves here). Make sure there is no film in the camera, then open the back. Take the carton frame with parchment paper and press it close to the film guide rail. Now, it must be possible to focus the new “lens”: gently vary the distance between the camera and the close-up object and watch the image on the screen until it’s sharp. If you can’t see enough, put a dark fabric upon your head as photographers did in former times!
The ascertained distance now may be fixed by the length of a string!
To take photos with this “apperatur:” just stretch the string until you reach the object, then put the string aside and press the button! It’s not essential to use the tripod. The following pictures are made without using one:
Hope you enjoy working with this macro lens!
