Today it’s common to use HDR or exposure blending for high-contrast scenes. Before digital, how did film photographers deal with limited dynamic range? Beyond graduated ND filters, what did they do when the transition wasn’t simple—such as a mountain breaking into a bright sky? Were those scenes handled with darkroom techniques, special filters, multiple exposures, or were some shots simply not practical on film?

The first generally known case of taking two different exposures of the same high dynamic range scene and combining the results was around 1850. Gustave Le Gray did it to render seascapes showing both the sky and the sea. Le Gray used one negative for the sky, and another one with a longer exposure for the sea, and combined the two into one picture in positive. Since then, combining multiple exposures to deal with wide dynamic ranges in a scene has been going on.

In the mid-twentieth century dodging and burning - selectively increasing or decreasing the exposure of regions of the photograph - became popular. This was done in the darkroom using masks to alter the exposure time of different elements in the scene when the image from a negative was projected onto the photosensitive paper using an enlarger. Ansel Adams raised the technique to an art form. All one has to do is study the prints he made of Moonrise, Hernandez, New Mexico to see this development. The negative was exposed and developed in 1941. Adams made over 1,000 prints as they were ordered by customers over the next 4 decades. He chemically altered the original negative at least once in the late 1950s to darken the sky. The prints considered most definitive weren't produced until the mid-1960s.

Adams also developed the Zone System to set exposure. Cameras didn't have built in meters until the middle of the 20th century. Before then a light meter was used, or the photographer just worked off the knowledge of what luminance a particular object would have under different lighting conditions. Adams divided the luminance range capability of his negatives into zones and would meter the brightest and darkest objects for which he wished to retain the details. He would then set exposure for the brightest and darkest areas of the scene to fall in the specific zone he planned to develop at the brightest/darkest capability of the papers he used to make prints with. Even then a negative could record more dynamic range than a print could reproduce. Thus the need for controlling contrast with exposure/developing times and for dodging and burning.

Different films also had different characteristics with regard to dynamic range and contrast. The amount of time used to develop exposed film also affected the highlights and shadows differently, as did the amount of time used to make the print.

Film photographers used many of the same ideas used today, just with analog tools. Multiple exposures and combination printing have been around since the 1800s; photographers could expose separately for sky and foreground, then combine them in the final print. In the darkroom, dodging and burning let them selectively lighten or darken parts of the image during printing.

In-camera, graduated ND filters were common, and for difficult shapes some photographers used split grads or even custom-cut masks placed in front of the lens, especially with large-format setups.

The exact approach depended on the scene and the film. Some films tolerated contrast better than others, and some subjects were easier to control than others. Not every scene could be rendered perfectly in one exposure, and sometimes photographers simply accepted the limitation or composed differently.

So the short answer is: film photographers used filters, masking, darkroom manipulation, and exposure blending—and yes, sometimes certain scenes were still difficult or impractical to capture exactly as the eye saw them.
