Resolution: Simply put Resolution is the amount of pixels (detail) in an image. Digital images are measured by the number of pixels per inch (ppi) a good ppi is over 300 by today's standards. Obviously, the higher the resolution, bigger the image file size. You generally want your image to be over 3mb(megabytes) with high quality 4K resolution images being over 10mb.
Exposure: The amount of light in a photo. Underexposed photos are dark with little detail; overexposed photos are too bright with lost detail.
Contrast: The difference in brightness between light and dark areas of an image. Contrast determines the number of shades in the image.
Highlight & Shadow: Highlights are the brightest elements in an image; shadows are the darkest parts.
Saturation and desaturation: Increased Saturation makes colors more vibrant (less black or white added). De-saturation makes colors less vibrant (more black or white added).
