A photogram is making a print in a photo lab without using a camera. By placing objects onto a piece of light sensitive paper in a darkroom, you can use an enlarger to cast light onto the paper and capture the silhouettes of the objects.
Begin by setting your enlarger to shed an area of light that is slightly larger than the size of your 8 x 10 piece of photo paper.
Next, lay out your photo paper under the enlarger where the light will shine down.
Then arrange your objects onto the paper in any fashion.
Switch the enlarger on and expose the paper for approximately 5 seconds.
Finally, carefully remove the objects and you're ready to develop.
