Upsampling and Downsampling.
Today in class I ran into something of note. It was a method of changing the resolution at which an image will print without harming it's pixels.
UPSAMPLING:
2.) Go to the File Menu and select Print Command [or just hit Ctrl + P]
3.) If you want the image to cover the entire printed paper, adjust the width and length of the image
To adjust resolution to an image that will be saved, or printed elsewhere;
To be safe, make a duplicate file!
1.) Go to the Image Menu and choose the duplicate command, name it as the image copy
2.) Go to the Image menu tab and select Image Size
3.) If the 'Resample' box is checked, it will rewrite pixels so that the Resolution remains high.
Having it checked will keep the image clear as you make it larger.
4.) In the resolution box, type in your desired resolution if you wish to print it
(make sure it is set to Pixels/Inch)
5.) Adjust the height/width of the image so that it becomes larger
DOWNSAMPLING:
To be safe, make a duplicate file!
1.) Go to the Image Menu and choose the duplicate command, name it as the image copy
2.) Go to the Image Menu and choose the Image Size command
3.) Here you can adjust the size of the image, uncheck the 'Resample' box to reduce the amount of pixels if you want to, otherwise keep it checked
4.) In the resolution box, type in your desired resolution if you wish to print it
(make sure it is set to Pixels/Inch)
5.) Adjust the height and width of the image, so that it becomes smaller
(make sure it is set to Pixels/Inch)
5.) Adjust the height and width of the image, so that it becomes smaller

UPSAMPLING
Upsampling is the type of resampling that Photoshop performs when you enlarge an image. When the image is enlarged, the original pixels will then be spaced further apart, and the application must "make up" the new pixels between them, using an appropriate approximation of the original scene.
DOWNSAMPLING
Downsampling is the opposite of upsampling, used when an image is made smaller. Although shrinking an image does not require filling in new space as in the case of upsampling, Photoshop may still use an approximation in order to preserve as much information about the image as possible.
