If you don t have sharpness, fine grain is wasted. If you want to use a fine grained, slow film, get a tripod and use it. Get a good viewer with achromatic lenses. If you have prints made, make sure the lab is making them as sharp as they can be. If you are printing them yourself get an excellent enlarging lens and make sure your enlarger is aligned.
Illumination is an important consideration.
Ideally, try to photograph some scenes around your home in different types of light so you can learn to predict how light affects the scene. Try to imagine the scene you are about to photograph in different light Consider photographing in open shade. It may not strike you as being as beautiful as a sunny day, but you might be surprised by how well it works for some scenes. Ninety percent of my award-winning images were made in subdued light. If you photograph in subdued light you will probably want to try to eliminate the sky from the image.
