Adobe Lightroom and Adobe Lightroom Classic are two different software products offered by Adobe. Adobe Lightroom is a newer product that is offered as a subscription-based service, while Adobe Lightroom Classic is a traditional software product that you purchase outright. Both products offer similar features for managing and editing your photos, but there are some key differences between them. Adobe Lightroom is a cloud-based service that offers more collaborative features and allows you to access your photos from any device. Adobe Lightroom Classic is a desktop-based product that offers more advanced editing features and gives you more control over your photo management.
