How do you read the built in light meter on your Camera?
I want to know how to read the light meter in my camera. I have a Nikon N55. I want to know how to read the numbers. What do they mean. I want to know how to adjust my aperture and shutter speed accordingly to what my light meter tells me. Thanks any help would be fine.

Unfortunately, this is a more complicated question than you probably realize. I’m not personally familiar with the Nikon N55, but I’m guessing that the numbers you’re referring to on your light meter are -2, -1, 0, 1 and 2. These numbers refer to “stops” underexposed or overexposed according to your light meter.
Stops are increments of light received by your film. If you manually matched your exposure on the film to the camera’s light meter reading at the 0 mark, this would be considered proper exposure by your camera. More exactly, the amounts of light hitting your piece of film, when averaged together, would equal medium grey (which is exactly halfway between black and white). For example, if you photographed a white wall at “proper” exposure, the film would come out grey (underexposed). Or, if you photographed a black wall at proper exposure your film would come out grey (overexposed).
Thus, the camera’s light meter reading is to be used as a guideline for producing proper exposures. If you want more information on how to do use this meter, research “Zone System” on the internet or e-mail me!

It’s not easy,and there is not enough space here,but I’ll try :
“f”.stops are about the lens.1.2 ,2.4, 4.5, 5.6 ,8 ,11 ,16 ,etc
-shutter speed are from “B” (the time,manual, you chose,maybe a long one) to ,1/2″ , 1/4″ ,1/8″ ,1/15″ ,1/30″ ,1/60″ ,1/125 “,1/250″ ,1/500″ etc,of second..
Having a fixed shutter time(ex. 1/125″) and a f.stop,as f 8,you have to know that the light passing through the lens,can change in this way:
You go from f 8 to f 16,you’ll have the half of the light passing through the lens.The same if you’ll use 1/250”,maintaining a f.8.
Each time you change one of the numbers,you can double or half the light going on the film.
When you take the exposure on a subject,you should ignore the bright and dark areas,because can give you false lectures of the light. The exposure meter of the camera measure the “reflexed light”.
A separate exposure meter for “inciden light” can give you a reading,that can consider light in “average”.Giving you possibilities to have a better exposed picture.
Example: if you take the light on a a white t-shirt of a person,the exposure meter of the camera will tell you to ” close the f.stop of your lens or to use a fast speed of the shutter.
BUT,while the t-shirt will result well exposed,the face of the person and other particulars,will be dark enough .
On the other side: if the t shirt is black,same situation.The exposure meter will tell you to use,OR,a longer shutter time,or to open more the diaphram(the f.stop).In such a case,the t -shirt will result well exposed,but the face of the person and maybe other particulars,will be overexposed,white.
If you are using the exposure meter of your camera,I can suggest to read the light on a 18% density-gray cartoon under the same light of the subject,or,more empiric,to read the light on the palm of your hand(under the same light that is receiving the subject.It’s almost equivalent to the cartoon 18%).
Aftter all this,you have to know that big f.stops 1.2 ,3.5 ,4 are giving you a little depth of field,therefore you have to be sharp in focusing the subject.
f.stops as 11-16-22 etc are giving you more depth of field.
Speeds as 1/30″ ,1/60″ ,1/125″ can be considered as “slow ones”. This means that if you are not steady,while taking the picture,the subject can result as “moving” and the quality of the image,can be bad.
With the experience,and making mistakes,you’ll be able to use your camera at the best. At that point,you’ll have another “problem” : how to use the colors,the composition,the point of wiew,etc to be able to transmit to the people your concepts…..
