Document Resize (AF Photo)

[Musaffar]

Hi 

I'm resizing an image using document resize, making it smaller.  Height and width proportions are constrained and DPI settings are correct, however, after the image resized to it's new smaller size, it looses sharpness.  Photoshop seems to be doing this with a much better resulting quality.

Am I missing something obvious?

Kind Regards

What are the image's original pixel dimensions, and what dimensions are you resizing it to?

Which of the 5 resampling methods have you tried?

I suggested these resampling labels some months ago:

Nearest Neighbor(hard edges)
Bilinear (reduction)
Bicubic (enlargement)
Lanczos 3 (high quality)
Lanczos 3 (highest quality)

You are probably already using Bilinear (default in Photo) so well ...

The default in Photoshop is automatic and it will often select bicubic sharper which delivers quite impressive and pleasing results:

Example image (crop) resized in Photo with bilinear:

Photo bicubic:

Photoshop bilinear:

And finally what you were used to : Photoshop  CC 2020 automatic (but clearly bicubic smarter) 

It is obvious that Photoshop does resize with sharper results and that bicubic sharper is a one shop stop resize method for probably must use cases.

So... you are in Affinity Photo, not Photoshop. You have to apply sharpening manually after resizing.

Can you compare PS bicubic sharper and AP Lanczos? These are the contenders here..

a) Photoshop (Bicubic Automatic = Bicubic Sharper when reducing the size) -- noticeable sharperning but practically no sharpening artffacts:

Are you sure you have these labeled correctly? I ask because to me the Photoshop one is the worst because it has the most visible halo effects, particularly along the edge transitions between the black pants & skirt & the lighter colors, & slightly more stair-stepped blouse sleeve edges than even the Photo (Lanczos Non-Separable) version.
