Best way to both resample and resize and image

Hello all. What steps do I take in what order to both resize and resample an image to fit a specific size/resolution?

 

An example: 

- I have a 300 ppi image that is 10.26” x 10” and 300 ppi.

- For this display, the image need only be 120 ppi. I can resize it down (uncheck resample) to get to 26.65 x 25” at 120 ppi.

- However, I also need it resampled up to 50” x 50”, still at 120 ppi.

 

What steps in what order are the best way to ensure the best result? (I AM aware of the basic issues with resampling and it’s limitations.) I've done some experimentation but haven't been able to get my head around it. Resize first and then resample, resample and then resize, or is there is another BEST method to get it where I need it to be?  Could someone outline the steps? Hope that makes sense.  Mac 10.15.7 and  Photoshop 21.2.4. Thanks!

You set everything in the Image Size dialog all at once. Check resample and uncheck the link symbol that contrains proportions.

Got it! Hadn't tried that. In the resample drop-down, do I set it for Enlargement--since I am going larger, even though the PPI is going down?

Ppi going down is enlargement. Pixels per inch, remember? It means exactly what it says.

 

The resampling options are a different matter. It basically determines how much sharpening is applied in the process. Any resampling will soften the image somewhat, but extra sharpening doesn't normally look good when upsampling. So Bicubic Smoother applies very little, and is therefore preferred when upsampling.

 

Downsampling can handle a lot more sharpening without introducing artifacts, and so Bicubic Sharper is intended for that. Personally I think it overdoes the sharpening, so I prefer Bicubic Smoother for everything, and then I add my own sharpening as applicable.
