Gratis, or without the monthly fee. If you ever wanted to try Adobe Photoshop, yet didn’t want to pay a monthly fee, I have been told you can download the 12 years old version now. Called Adobe Photoshop CS2.

My contact says he has used this version for years and likes the control that it gives with adjusting lighting, file size, retouching etc., but other photo applications allow you to resize photos with fewer steps. The other free online photo editing service that my contact says some professionals use is called GIMP https://www.gimp.org/
