Tip: improve the quality of your photos by reducing and enlarging them in Photoshop

Probably reduce our photos to upload them to the internet, send them by mail, or simply to have them at less resolution is one of the actions that we use most every day when we work with Photoshop.

And normally, to do it, we do it in the following way: Image – Image size, we give a new dimension in pixels and press OK. But rarely do we notice that there is a pull-down menu where we can tell the program how to re-sample the image, to optimize this resizing.

To improve the quality of a reduced photo it will be enough to use the most focused bi-cubic option (optimal for reductions) that basically applies the appropriate focus mask according to the output resolution.

The differences are noticeable:

Reduction by default:

reduction 1

Bicubic reduction more focused:

reduction 2

I guess you appreciate it, although depending on the photo we will get better or worse results. Normally, the greater the depth of field, the more we will notice the difference.

The opposite case is also evident. If we want to enlarge an image, we will use smoother bicubic (optimal for enlargements) with what we will achieve that the images will be less pixelated and soften better, when we move from a photo with few pixels to a large one.

Ideal if we want to use it to interpolate photos to large sizes.

Extension by default:

More smoothed bicubic magnification:

expanded1

Well, we already know something else, although we have the problem that it is not very comfortable to have to change this option every time we want to reduce or enlarge a photo with this configuration, but there is also a solution to this.

If usually what we do is reduce photos, we can configure photoshop so that our default option is more focused bicubic . For this we will only have to go to

  • Preferences> General> Image interpolation> more focused bicubic

And we will have it configured to be the default option.

For the opposite case, then the same.
