Picture squished.

Hi Guys, this is my first post on the forum. Can you give me a heads-up on this? Keep it simple.
If I save a JPG 5" x 8" book cover Photo from PHOTOS after making minor adjustments in EDIT and save to pictures, the picture saved appears as if in vertical format (squished) and not in horizontal format 5" x 8". If I want to transfer the said squished picture, sometimes it opens out to the correct horizontal format, sometimes not. Grrrrr! Any ideas?
Ideally I would like to save the edited picture to PDF but PHOTOS does not give that option.

Hello Stuzapem,

Welcome to the Forum!

I agree that PHOTOS does not provide a choice to export a picture into PDF format.

After successfully editing a picture in PHOTOS, I opened the result in Affinity Photo where I could export to PDF.

Looks to me like you may need an additional piece of software to accomplish your goal.

Perhaps someone else on this forum with more experience will chime in with another idea or process that will work.
