- -TIFF – tagged interchange file format; lossless – doesn’t compress, doesn’t lose information when you open and close it
- -JPEG – Joint Photographic Experts Group; lossy – loses information; compresses and becomes a smaller file, takes up less space
- - PSD – Photoshop default; lossless
- - Bitmap (bmp) – useable under certain circumstances; overly simplistic – designed for line images, clip art. Very basic noncomplicated images; lossy
- - GIF – used for graphic design; lossy

a tool in Photoshop and other image editing programs which can move and stretch the brightness levels of an image histogram. It has the power to adjust brightness, contrast, and tonal range by specifying the location of complete black, complete white, and midtones in a histogram allows for individual adjustment of the highlights, midtones, and shadows. |

- tool that can take input tones and selectively stretch or compress them.
- Unlike levels however, which only has black, white and midpoint control, a tonal ____ is controlled using any number of anchor points (small squares below, up to a total of 16).
- The result of a given ____ can be visualized by following a test input tone up to the ____, then over to its resulting output tone.
- A diagonal line through the center will therefore leave tones unchanged.

- the pixel value in an electron image that represents its lightness value from black to white
- ranges from 0 (black) to 255 (white)
- the differences in density (values from black to white) or apparent brightness between adjacent tonal areas of a negative or print image
- way to adjust the tones of an image
- box with two sliders, one for each of them

Definition
- vertical bar graph displaying the distribution of the tonal values of the pixels in an image. Used to identify contrast and dynamic range in photo-editing programs
- the x-axis represents the tonal value of the pixels (0-255)
- the y-axis represents the number of pixels having that tonal value
- peaks and valleys of the it represent the number of pixels containing those tones.
- an image with full tonal range will have some tones in every part of it

where digital tonal range is defined. And not only defines the digital tonal range, but it allows us to shorten it. By shortening the tonal range, we are forcing image pixels to look more alike, thus decreasing contrast. used to reduce image contrast by darkening lighter tones and lightening darker ones - bringing the extreme tonal values closer to the middle of the range. |

- method of reducing image file size by discarding information that is least perceptible to the human eye, thus producing slight degradation of image quality when restored.
- Removes more image data and often results in reduced image quality; produces smaller files - shouldn't be used to save an original scan

- amount of contrast applied to an image;
- midtones and how they’re adjusted to affect the desired contrast of the image.
- relative brightness of a middle value in an image
- adjustments to it lighten or darken the middle tones of the image without changing the shadows and highlights
- can range from 0.10 to 9.99
- if you drag the middle slider to the left, or increase its number, you will lighten middle tones; if you move the slider to the right, you will darken them
