Does photo size affect quality?

The most common side effect of scaling an image larger than its original dimensions is that the image may appear to be very fuzzy or pixelated. Scaling images smaller than the original dimensions does not affect quality as much, but can have other side effects.

What is the relationship between resolution and file size?

Higher resolution values pack more pixels into a linear inch, resulting in a smaller print size. And lower resolution values pack fewer pixels per inch, giving us a larger print size.

Is image size the same as resolution?

Resolution is determined by the number of pixels, or dots, in a linear inch. The image size is determined by the resolution multiplied by the height and the width of the image. Your height and width will be determined by how you received the image, be it a camera, scan, etc.

Does making an image smaller reduce resolution?

The short answer to your question: Yes, you will lose image quality. If you resize your images down to a smaller size, and then size back up again, your image will be a lot less clear. By resizing the size of the image, you actually reduce the mega pixel count of the photo.

What determines the file size of a photo?

There are three main factors that determine the size of an image file: pixel dimensions; image format; and colour depth. This refers to the number of pixels in an image: the more pixels that are present, the larger the file size will be.

How do I determine the size of a file in resolution?

Size calculations File size can be expressed as the resolution (the image width multiplied by the image height) multiplied by the bit depth (the number of bits needed to store colours).

What resolution do I need?

It’s best to look at the pixel dimension of your images as you’re making them. As long as they’re at least about 1024 pixels wide (for a horizontal image) they should be fine for teaching. The standard resolution for web images is 72 PPI (often called “screen resolution”).

What does low resolution mean on a photo?

A low resolution means that the density of the dots that make up the image is low, so if the image resolution is low, the photo will be blurred or look jagged and rough.
