GIMP vs Lightroom:

GIMP and Lightroom are two distinct image editing software with differences in terms of price, focus, features, and workflow. GIMP is a free and open-source software suitable for various tasks such as photo retouching and graphic design, while Lightroom is part of Adobe’s subscription service and primarily focuses on organizing and processing photos. Both software has advanced tools, but Lightroom’s features include batch editing, presets, and non-destructive editing for efficient photo processing, while GIMP has a more customizable interface for complex image editing tasks.

However, GIMP’s interface can be overwhelming for new users, especially those used to simpler software like Photoshop or Lightroom. The software’s design is tailored for more intricate and customizable image editing tasks. Additionally, since GIMP is open-source, there is no official technical support, although there are several online resources available to assist users with troubleshooting issues.
