Both. Ansel Adams used 8 x 10 glass plates in his field camera, but he also shot pictures with film cameras, such as a medium format Hasselblad, a Zeiss Milliflex 35 mm rangefinder, and even Polaroids.
The Zone System is a photographic technique that is used to determine optimal film exposure and development. The technique is based on the sensitometry studies during the 19th century. It was developed by Ansell Adams and Fred Archer.
Just about anything he could get his hands on, including Leicas, Hasselblads and view cameras.
Roll film was significant because before it was invented, all photos were taken on sensitized glass plates. Glass plates are very heavy, and you had to put a new one in the camera after each picture was made. With roll film you could put one in the camera and take many pictures, then wind it off and put it in your pocket when it was full. After film had been around a few years, photographers who had glass plate cameras had almost all modified their cameras so sheets of film rather than plates could be used. You still had to change after every shot, but film was far lighter than plates. Even with the advantages film gave, plates were made for many years. Plates are better than film for professional astronomy because they are rigid. This is important because on large scientific telescopes, the cameras are mounted underneath the telescopes and the film is horizontal. Film will sag in the middle; plates never will. It made photography available to the general public who did not have the technical knowledge to deal with plates and large cameras. George Eastman Kodak invented the roll film and its camera in 1888.
Actually he did use the color system earlier on in his life. Mary Alinder found some of his old color negatives and she asked Ansel if she could produce them and he agreed, but after producing a couple pictures with her husband, Ansel ordered them to stop.Adams did a lot of color work. He was a consultant for Kodak and Polaroid and tested color materials for both. He also did a lot of commercial work to support himself. He was very old before his black and white fine art work began making him much money. Check out the book, Ansel Adams in Color.
Roll film replaced camera-speed roll paper. George Eastman's original Kodak came to the user loaded with a roll of camera-speed paper (as opposed to enlarging-speed paper, camera-speed paper was usable to take pictures on). You shot the 100 images on the roll and sent the camera, along with one dollar, to the Kodak Labs in Rochester, New York. There they would develop the paper roll, strip the emulsion from it and bond it to a strip of celluloid for printing. What replaced glass plates was sheet film, for all uses except astronomy. Astronomers continued to use plates because they're more dimensionally stable than film, and they don't sag when you put them in a camera that's tilted back at a severe angle. - - - - - Roll film replaced individual photographic plates, which had already progressed from coated glass plates to emulsion-coated stock. Glass plates were still popular for their comparative clarity. This "film" had a light-sensitive material in a thin layer attached to cardboard, which was developed and transferred to glass for printing.

The camera. "Film" as you know it came much later. It was preceded by coated glass, copper and tin plates, not necessarily in that order.

Are you asking about film used for still photography, or 'film' as in 'movies'? The first flexible film (as opposed to glass plates) for still photography was around in the 1930s, there was a colour movie system demonstrated in the 1920s. Neither was very true to life.
