[100IH]

I see that the picture was taken with very bright flash lighting to get a good image in a dark workshop. Notice how the running board step plate is washed out of any detail and that there is some detail outside the open door. Light gray becomes washed out to look white. It's about the limited range of contrast that the film can capture. The old adage for the best lighting for pictures is before 11 AM and after 3PM when the light is not so contrasty.
