How do I resample an image in Photoshop?

Should I resize or resample?

When you resize an image and do not resample it, you change the image’s size without changing the amount of data in that image. Resizing without resampling changes the image’s physical size without changing the pixel dimensions in the image.

What is the difference between resizing and scaling an image?

Resizing means changing the size of the image, whatever the method: can be cropping, can be scaling. Scaling changes the size of the whole image by resampling it (taking, say every other pixel or duplicating the pixels*). The new size is different, but the content is quasi-unchanged.

How can I improve the quality of a photo?

The only way to resize a smaller photo into a larger, high-resolution image without highlighting poor image quality is to take a new photograph or re-scan your image at a higher resolution. You can increase the resolution of a digital image file, but you will lose image quality by doing so.
