All of these infrared black & white pictures was made on the now discontinued KODAK High Speed Infrared bl&w film 2484.

The camera was mounted on a tripod, much because of the infrared gelatine filter KODAC Wratten no.87 or simply called »black filter«, placed in front of the lens. It blocked all the visible wavelengths out, and only let through the infrared light. This made it impossible to hold the camera by hand, because the viewfinder was blacked out.

The resulting pure IR photographs captured on the negative film was quite grainy due to the small format of the frame, 24x36 mm combined with the high speed emulsion.

 

This makes the atmosphere and light in the enlarged photographs beautiful in big size prints.

 

The notable halation effect or glow seen in the highlights of these photographs is an artifact of Kodak High Speed Infrared black-and-white negative film and not an artifact of infrared light. The glow or blooming is caused by the absence of an anti-halation layer on the back side of the Kodak film. The light bounced back and forth in the plastic layer causing the halo. The bouncing light would usually be absorbed by the anti-halation layer in conventional films, preventing the light from creating these effects.
