Photos and the Creative Commons License
I had a subscription to Adobe Stock for about a year. I thought it would be great, but it wasn't. When I cancelled my subscription I had to use all my credits up and I had a very hard time selecting photos. It turns out that often stock photography is not that great. I found the photos were often contrived or of poor quality.
Using photos with the Creative Commons License allows me to use photos from respected photographers. These photos have more heart and soul. Using them also gives me a chance to participate more in the internet community.
