Upsampling is when you take a low quality photo and add pixels to make the photo look better when it is printed. Upsampling is beneficial, but depending on the image you may not need or want to upsample. Each image is different. To upsample an image it is best if you know the size of the print you want and what kind of printer you will print this image from, this will help you decide how high the resolution needs to be on your image

Question 9

Downsampling

Answer 9

Downsampling is when an image (or digital audio) is made smaller. This can be done in a couple different ways. One way makes the image smaller by decreasing the overall pixel amount, and the other by decreasing the bit depth of an image

Question 10

Straighten

Answer 10

Adjusting crooked images, usually done to make the horizon straight across

Question 11

Fill

Answer 11

these tools fill a selected object, area, or layer with color

Answer 13

PSD, which stands for Photoshop Document, is the default format that Photoshop uses for saving data. PSD is a proprietary file that allows the user to work with the images’ individual layers even after the file has been saved

Question 14

JPG

Answer 14

JPG files, also known as JPEG files, are a common file format for digital photos and other digital graphics. When JPG files are saved, they use “lossy” compression, meaning image quality is lost as file size decreases

Question 15

TIFF

Answer 15

A TIFF file, or TIF file, stands for Tagged Image File Format. TIF files are a common file format for images, especially those used on graphic design.
TIFF files can be saved without compression, or they can be compressed to lower file size, similar to JPG files. TIFF files are commonly used in print design and desktop publishing because they can store large, high quality images such as photos.

Question 16

PNG

Answer 16

PNG (pronounced ping as in ping-pong; for Portable Network Graphics) is a file format for image compression that, in time, is expected to replace the Graphics Interchange Format (GIF) that is widely used on today’s Internet

Question 17

Clipping mask

Answer 17

A clipping mask is a group of layers to which a mask is applied. The bottommost layer, or base layer, defines the visible boundaries of the entire group. For example, suppose you have a shape in the base layer, a photograph in the layer above it, and text in the topmost layer.

Question 18

Heal

Answer 18

The spot healing brush is the default healing tool in Photoshop and can be used to clone areas from an image and blend the pixels from the sampled area seamlessly with the target area. The basic principle is that the texture from the sample area is blended with the color and luminosity surrounding wherever you paint.

Question 19

Clone

Answer 19

The Clone Stamp tool paints one part of an image over another part of the same image or over another part of any open document that has the same color mode. You can also paint part of one layer over another layer. The Clone Stamp tool is useful for duplicating objects or removing a defect in an image.
