Same Photos but SIZE don't match

[ANDRO-ART.com]

Hi,

please help me to understand.

Same photo if i chose to edit from Apple photo with Affinity direct: i goth the resolution is 5568x3712 the size is 18x12 inch

Same photo first export to folder from Apple photo then opened to Affinity: i got the resolution is 5568x3712 the size is 77x55 inch

Then i star the editing/cropping.... the final print, photo, with magnification is completely different.

What i am doing wrong???

It depends on how you define "Size".

The pixel quantity is the same, so the image size (resolution) is the same.

If you look at the DPI setting, you will see that each image's DPI setting is different. The DPI setting doesn't really matter, although some programs do use that to physically size the picture when you drop it in to a page.

e.g. If you created an Affinity Designer page, set at 300 DPI

A 300 DPI image dropped in would be sized at 1 inch, the same image set to 150 DPI would be sized in at 2 inches.

If you scaled the 150 DPI image down to 50% the end result (quality wise) would be the same because it then has the same number of pixels in an inch (300).

P.S. You can change the pixel setting in Photo so they match. In Document > Resize Document change the DPI but untick Resample or it will change the resolution (pixel quantity).
