If you are not subscribed to Creative Cloud, a great alternative is VSCO. VSCO has an abundance of filters and editing tools that are similar to Lightroom. You can use this app for free, or you can use upgrade for a paid subscription (running at $19.99/yr) that features their full library of filters. If you already have a VSCO account, their blog already features plenty of tutorials and inspiration. However if you’re a beginner in the photo editing game, this post could be of use.
