Resizing and Image Quality
You’ve taken that perfect photo in the perfect moment and now you want to print the perfect poster to display on your wall. The problem is you want to print it large but for some reason, the resolution just isn’t there to produce a quality print. Again, the resolution of your photo is crucial for the quality of your print.
Perhaps the photo was taken using an old camera. Maybe the photo was taken using a phone camera and/or edited using an app which can greatly diminish resolution. Or maybe the photo was uploaded to Facebook or Instagram. The problem here is that these services restrict the size of the image and resize it before posting it to their site. This is a problem for those that want to print large posters as when the lower quality image is then used the resulting print will be of poor quality.
Resizing can go in two ways: you can make images smaller or you can make images larger. Making images smaller discards pixels. Making them larger adds pixels, resulting in a loss of Image quality. Excessive enlargement will produce blocky-looking and/or fuzzy pictures. Resizing works best when you’re reducing the size of the photo to fit a certain dimension or decreasing the file size.
Essentially resizing images changes the resolution of the image, the fine detail and the outcome of your print.
