All of the following tools and resources for Photography are available online, most of them for free – though sometimes with limitations (e.g. time, number of downloads etc.).
Resources

Tools
Clearly the dominant provider of digital photography related tools is Adobe through its Adobe Creative Cloud services (previously Adobe Creative Suite) including Adobe Photoshop, Adobe Lightroom etc. Most of the apps are available for free trial, but convert to a pay-by-subscription model after a time limit. (For a limited time during Covid-19, Adobe offered all their licenses for two months for free for students and registered users.)
