One of the most important aspects of photography is understanding film speed, otherwise known as ISO, and how to apply it to the subject or event you are shooting. The difference between a wasted photo shoot and a valuable addition to your portfolio might be forged by your knowledge of the differences between 400 and 800 film speeds.
Understanding What ISO Means
The acronym ISO is a bit misleading. It stands for International Organizational Standard. To photographers and enthusiasts, ISO is the ranking system for film speeds. The film speed translates to how sensitive the film is to light. The lower the ISO, 100 for example, the longer the film will need to be exposed to light to make an image. If you increase the ISO, you'll need less light to take a picture.
Using 400 ISO
You can use 400 ISO film for a number of situations because it's a very versatile film speed. A 400 film speed will allow you to shoot either outdoors during daylight hours or indoors, and it is also good for capturing actions shots like sporting events. You can shoot with or without the flash with a 400 film, but it is advisable to use a flash indoors or in a twilight setting.
Using 800 ISO
Unlike 400 speed film, 800 speed is more geared toward shooting in low-light settings without the flash. The 800 speed film also extends the range of the flash, if you choose to use one. An 800 ISO film will capture action shots and fast-moving objects without the blurring effect you get from using a slower film speed. However, the image might develop more grainy or noisy than images taken with a 400 speed film.
Choosing Between the Two Speeds
If you are shooting sporting events or shooting in situations that require you to capture action during regular daylight conditions, using a 400 speed would be your best bet. If you use an 800 speed film in these situations, images tend to be a bit grainy, which compromises quality. However, if you're shooting an event like a wedding, especially when the day gives way to night, an 800 speed film will be your best bet in dealing with capturing images in various low-light settings. As with any shoot, consider all the conditions you might need to face and choose the best film speed to handle those variables.
