HOW TO SET YOUR LIGHT METER

1) Look at the box of your film. There are little icons for light bulb and the sun, then there is a number near one of those symbols. The symbol without a little number directly following it is the light your film is balanced for. (Tungsten -inside, light bulb OR Daylight - outside, sun) your film will be called 100D for example this means that its ISO/ASA is 100 in daylight. Only pay attention to the symbol without a number directly following it. The number directly following it is the filter you could use to balance your film for a light it was not rated for.

Basically follow the symbol without a number directly to the right of it over to the number that is further to the right without any letters in it, usually 100, or 250 etc. That is the speed of your film.

Make sure you punch in the speed of your film into your light meter so that your light meter reads the light correctly for you particular film.

I know this is confusing. I tried to find an image online of the camera box but could not -

just know that for color reversal it can only be 100D which means that you should shoot in daylight unless you want it to look brown inside and set meter to 100ISO/ASA

-For B&W it is around 200 and it doesnt matter if it is inside or outside. The light will look relatively the same - because your are not dealing with outright color.
