Is it appropriate to decrease or increase the resolution of an image in Photoshop? Why or why not?


Answer by  lgk (2426)

It is appropriate to do which ever the photo needs at the time. Reason being it saves not only on tons of retakes that you may not always be able to do, but allows you to get better detail out of your photos, even if they are for personal use.

Decreasing the resolution of an image in Photoshop is fine. However, increasing the resolution is not. When you increase the resolution of an image, it may appear to be grainy and very bad quality. Stretching the image is the worst thing to do, if you change the aspect ratio, objects in the image may look longer or wider than normal.

You cannot use Photoshop to increase image resolution beyond what it had at the time you took the picture. You can reduce resolution by resizing. You may need to resize if you have a limit as to the file size of image you are allowed to upload to some websites.

You can decreast the resolution as much as you want, but when increasing it there are limits. Going much about 150% is not advisable.

It depends what you're using the image for. Web graphics are at lower resolution (often 72 dpi) so lowering a photo's resolution for web use is pretty standard.
