ISO, ASA, shutter speed, aperture, f/-stops, cloudy, daylight, nighttime, long exposure... The world of photography houses a whole new language and it's not always easy to know which film to use when to get the best results. I'm going to list some quick tips to hopefully help you.
ISO (or ASA) is a scale which determines how sensitive your film is for light, and in effect how “fast” the film is. Fast for what you mean?
Say your favorite band is playing! Or any band. You’re going to a cool concert! Which film are you going to stick in your camera? If it’s an indoor event, a club for example, then it’s probably going to be very dark inside, except for the spotlights. You should bring a film with a higher ISO, 400 or maybe even 800 so that, even though there is not much light inside, the camera and the film will work with what is there to take crisp and clear shots.
Don’t do like me and bring a ISO 100 film. Look.
Same if you’re going out to take some night shots of your city. High ISO film. Otherwise you might end up with green and red lights from possible UFOs…
While this might be cool sometimes, it’s also cool to have pictures that come out right, especially if you’re on holiday and won’t have the opportunity to go back soon.
If you’re familiar with the 24 hour clock system, here is a good way to think:
If it’s 20.30 at night, it is dark, the hour is MUCH, you need a MUCH number high film. 400 or 800.
If it’s daytime and full daylight, only a LOW number of hours of the day have passed, you need a LOW iso film.
And maybe MOST IMPORTANT of all, if you have a wide selection of different ISO films, REMEMBER to immediately change the ISO setting on camera the second you’ve loaded the film to the correct number.
Otherwise you might do like me and have the camera set to ISO 100 but with a ISO 400 film inside, shooting it inside… Then you’ll end up with blurry pictures none the less!
Hope this helped!
But remember, even accidents can be happy! :)
