The Right Light
In photography, lighting is everything. When shooting color film especially, try to avoid direct sunlight in midday. It is usually harsh and difficult to expose correctly, leading to washed-out photos and a stark mood. If you do shoot in direct sunlight, play with shadows and contrasts, and realize that full-sun shots are some of the toughest to master. Almost invariably, morning and evening light, where the sun shines at a lower angle and has more tonal quality, is the best. Try shooting pictures during these times of day, and resting your camera when the light is not right. And don't hesitate to photograph in foul weather. Often fog, clouds, and rain produce some of the most dramatic effects in photography, and will soften an otherwise harsh sun, allowing for better color saturation in your photos.
Is All Film Created Equal?
No, it's not. Different films record colors in different ways, vary in their levels of fine-grain resolution, and work at different shutter speeds. And then, of course, there is slide film and print film. Carry several different film speeds, and while it's true that with one camera you'll probably use up your film before switching to another film speed, you can still plan ahead to take advantage of the day's light and the correct film speed for it. If it's dark, you can use 400 ASA to get a faster exposure. In bright sun, use 50 ASA for deeper colors and minimal graininess. Beyond that, you'll need to experiment. Some films, like Fuji slide film, emphasize blue and green hues, while others, like Kodak Kodachrome, lend an orange tone to your pictures. For a general-use film, try 100-speed slide or print film. Fujichrome Velvia and Fuji-chrome Provia 100F are two excellent slide films, and Kodacolor is a standard workhorse print film.
