Try Ilford Universal 400, and shot with a wide-angle lens, like 28mm. When you go to make the print, just enlarge the center part of the image, and it will look normal.(posted 8670 days ago)I make my favorite grainy images with an Olympus Pen-F camera, which makes a "half-frame" negative. Enlarging the image to 8x10 produces a beautiful grainy picture, sharp in focus yet soft from grain.
Another avenue is to use a Minox. I think there is one model for about $300. Or you can buy a used model. If you go this route, there are many support groups, and there is information on how to make a well-developed roll of negatives, in case you want to develop the film yourself.
