How resolution and colour depth affect file size and image quality?
Changing the image resolution will affect the file size of the image and the quality of the image. Image resolution is measure in DPI, which is Dots Per Inch, this means that if you increase the resolution then the DPI will increase and the quality of the image will get better as a result as there are more pixels that make up the image, so the image will be more distinct and sharper. When the image resolution is increased the image has more pixels, this is the exact opposite to the compression techniques, this means that the file will get a lot bigger as the number of pixels increases. Decreasing the resolution, however, will make the image quality lower but will reduce the file size.
Does the thickness of a lens affect the image?
If the lens are thicker it affects the image distance.
How does file format affect image quality?
By reducing the size if a image
What factors determine the overall jpg quality of an image?
The overall quality of a JPG image is determined by factors such as resolution, compression level, color depth, and the amount of detail in the image.
How does framing affect the quality of the picture?

Does focal length determine the image quality?
Focal length does not directly determine image quality. However, different focal lengths can impact the perspective and composition of an image, which can indirectly affect the perceived quality. The quality of an image is more dependent on factors such as lens quality, aperture, shutter speed, and sensor size.
What does stopping down mean in photography and how does it affect the final image quality?
Stopping down in photography refers to decreasing the aperture size to allow less light to enter the camera. This results in a larger depth of field, meaning more of the image will be in focus. Stopping down can improve the overall sharpness and clarity of the final image, but it may also introduce diffraction, which can reduce image quality by making the image appear softer.
What is the significance of the aperture diameter in photography and how does it affect the quality of the image?
The aperture diameter in photography controls the amount of light that enters the camera. A larger aperture lets in more light, resulting in a brighter image with a shallower depth of field. A smaller aperture lets in less light, resulting in a darker image with a greater depth of field. The aperture also affects the sharpness and clarity of the image, with a smaller aperture generally producing sharper images.
What is the function of the aperture iris in a camera and how does it affect the quality of the image?
The aperture iris in a camera controls the amount of light that enters the camera lens. By adjusting the size of the aperture, the photographer can regulate the exposure of the image. A larger aperture lets in more light, resulting in a brighter image with a shallower depth of field, while a smaller aperture allows less light in, resulting in a darker image with a greater depth of field. The aperture also affects the sharpness and clarity of the image, as a smaller aperture (higher f-stop number) can increase the depth of field and improve overall image sharpness.
What is an aperture on a camera and how does it affect the quality of the photographs taken?
An aperture on a camera is the opening through which light enters the camera lens. It affects the quality of photographs by controlling the amount of light that reaches the camera sensor, as well as the depth of field in the image. A larger aperture lets in more light and creates a shallower depth of field, resulting in a blurred background and a sharper subject. A smaller aperture lets in less light and creates a deeper depth of field, keeping more of the image in focus.
Do digital photos from disc lose quality each time you print?
A JPEG image loses quality when it is opened and resaved due the compression algorithms. The more an image is opened and resaved, the more the quality can degrade. An image on a disc will not lose quality unless you resave it on a CD-RW. Opening an image to print will not affect the quality.
What are some common types of photo artifacts that can affect the quality of an image?
Common types of photo artifacts that can affect image quality include noise, compression artifacts, lens flare, chromatic aberration, and motion blur.
