Camera Research

Camera Iris (fstop)

A camera iris is the part of the camera that controls how much light comes through the lens. If the iris creates a larger opening, more light can get through; a smaller opening allows less light through. The light that the iris allows through hits the image sensor and that light gets recorded as electrical impulses that create the video.

Shutter Speed

Shutter Speed is one of the three pillars of photography, the other two being ISO and Aperture. Shutter speed is where the other side of the magic happens – it is responsible for creating dramatic effects by either freezing action or blurring motion. In this article, I will try to explain everything I know about shutter speed in very simple language.

ISO (Film Speed)

In very basic terms, ISO is the level of sensitivity of your camera to available light. The lower the ISO number, the less sensitive it is to the light, while a higher ISO number increases the sensitivity of your camera. The component within your camera that can change sensitivity is called “image sensor” or simply “sensor”. It is the most important (and most expensive) part of a camera and it is responsible for gathering light and transforming it into an image. With increased sensitivity, your camera sensor can capture images in low-light environments without having to use a flash. But higher sensitivity comes at an expense – it adds grain or “noise” to the pictures.

Depth of Field (DoF)

A basic definition of depth of field is: the zone of acceptable sharpness within a photo that will appear in focus. In every picture there is a certain area of your image in front of, and behind the subject that will appear in focus.
This zone will vary from photo to photo. Some images may have very small zones of focus which is called shallow depth of field. Others may have a very large zone of focus which is called deep depth of field. Three main factors that will affect how you control the depth of field of your images are: aperture (f-stop), distance from the subject to the camera, and focal length of the lens on your camera. Here are some explanations and answers to other common questions concerning depth of field.

Manual Mode
Align the mode dial correctly to the mode that you want to use, in this case the 'M', which stands for manual.
 Video Mode
Align the mode dial correctly to the mode that you want to use, in this case the illustration of the camcorder with the 'M'.
RAW Mode
Align the mode dial correctly to the mode that you want to use, in this case to RAW.
Changing the ISO, F Stop and Shutter Speed
ISO: Press the ISO button and change the settings on screen.
F Stop: Turn the aperture ring.
Shutter Speed: Turn and press the rear dial.
Zoom
Turn the dial on the rear of the camera until the screen zooms in or out.
