The issue is that you didnt expose your film correctly.
Whether we use a digital or video camera, we need to be in a position to assess exposure effectively. But first, we have to know how the aperture and the shutter work together. We also need to know how film handles light, and the connection between film light sensitivity and f/stops.
Lets take a glance at the key components.
Aperture and f/stops: the aperture can be an beginning in the centre of the lens through which light travels. The total amount of light which passes via an aperture is indicated by f/stops. The low the f/stop the more light that passes through the aperture. Opening one complete f/stop doubles the quantity of light entering the camera. F/4 admits twice the light of f5.6.
Shutter: the shutter is a mechanical system that controls the length of time that light is permitted to act on the film. Each time you open the shutter by one, we increase when we shut down the light by one we half the light, the light. Opening the shutter at 1 second permits twice the light as that of the second.
ISO (ASA ): means International Standards Organisation. The initials are utilized for film speed which charges light sensitivity. A film with an number 100 is twice as light sensitive as a film with an ISO of 50. The quicker the film, the more sensitive it's to light.
Many digital SLR have ISO options built-in for them. Should you be going for a low light image with a camera use a gradual ISO rating of 200 or upwards.
Obtaining the perfect exposure isnt simple, but there are several other ways of making it easier.
Using a light meter: there are two types of light meters,
1. Reflected-light meter (the same that's built into your camera) functions pointing the meter at your subject.
2. Incident-light meter: instead of pointing the meter at your subject, you place the meter at the camera and stand beside the subject. The light that falls on your subject may also fall on your meter.
The most common way is to utilize the meter included in your camera. All modern day cameras have per your request a reflected-light meter built in to them. But dont point the camera directly at your subject from 10 meters. This may most likely underexpose your image. Take the exposure reading up-close, then take your image and return to the starting place.
If we dont point them in the proper direction our photographs will get back too dark or too bright, it doesnt matter which metering process we use. The key is to understand where to point the meter.
When I take a landscape image I normally take five or six different readings. I simply take an reading with my light meter to record the foreground and a reading of the air.
If you're unsure take 3 or 4 pictures at different exposure settings. Dont let a perfect picture moment go by without recording it beautifully.
