F- Stop
- F-stop affects the depth of field in clicked pictures.
- The F-number of a lens is the ratio of its focal length divided by the diameter of the aperture.
- A Small F-stop number means the opening is a larger F-stop number means the opening is larger, lighter entering the camera. Similarly a larger F-stop number (remember smaller opening), requires a slower shutter speed.
Pixel
- Resolution refers to the number of pixels in an image.
- A pixel is the smallest unit of a digital image or graphic that can be displayed and represented on a digital display device.
- Pixels are combined to form a complete image, video, text or any visible thing on a computer display.
View Finder
- In photography, a viewfinder is what the photographer looks through to compose, and, in many cases, to focus the picture1.
- Viewfinders can be glass, as found in rangefinder and DSLR type cameras, or an LCD screen as found in mirrorless cameras2.
