How do I determine the pixel size of an image?

To figure out the image size, just follow these simple steps:

1. Multiply the width and height of the image, in pixels, to get the total pixel count.
2. Multiply the total pixel count by 3 to get the image size in bytes.
3. Divide the number of bytes by 1024 to get the image size in kilobytes.

How to calculate pixel scale for given setup?

We can calculate pixel scale for given setup with the formula below: When we consider imaging setup it is good to find out what factors are limiting our capabilities and to to fight them back. For low pixel resolution setups (3-4 and more arcsec/px) optics resolution limit is of low importance.

How does the measurement scale work in Photoshop?

Measurement scale. Setting a measurement scale sets a specified number of pixels in the image equal to a number of scale units, such as inches, millimeters, or microns. Once you’ve created a scale, you can measure areas and receive calculations and log results in the selected scale units.
