Upscaling Images: Luminar Neo Quality Comparison

I recently got the Luminar Neo software for PC, mainly to experiment with image upscaling. Here are a few examples showing where it works really well—and where it doesn’t.

I wanted to print a few casual smartphone shots as large canvas prints (over one meter wide or tall), so I was curious to see whether the quality improves or degrades when upscaled. Below, you’ll find zoomed-in examples to help you decide whether Luminar Neo can deliver the results you want before you make a purchase.

The original photo is only 3 MB in size, 2252×4000 px, taken with a Samsung S24 in Bristol (England, 2025).

Upscaling with Luminar Neo

I tried two upscales:

  • 2x enlargement: 4504×8000 px (132 MB)
  • 4x enlargement: 9008×16000 px (492 MB)

Plants are heavily altered

When using Luminar’s Upscale feature, you can clearly see strong differences in plant textures and details.

Upscale + Super Sharpen combination

Next test: what happens when you also apply the Super Sharpen feature? I tested two workflows:

  • First Super Sharpen (medium), then upscale 2x
  • First Upscale 2x, then Super Sharpen (medium)

For comparison, here are all four versions side by side:


The differences are only noticeable when you view them side by side. However: the best result was achieved by using the super sharpen function first and then upscaling the photo.

I’ll will buy both a print of the original and one processed with Super Sharpen (Medium) plus 2x upscaling, and share the results in the forum thread.
