Best Free Image Editor for Linux
  • Luminance HDRGIMP

    "Currently the only freeware package I am aware of that can be called an advanced image editor.

    If you are inexperienced at using image editing programs GIMP will likely be too overwhelming to start learning on as it has a steeper learning curve but it is feature rich. It has lots of advanced features and can do almost everything the Photoshop can do.

    Its multi-windowed interface makes it a little unusual if you're used to a windows program." (Review)

  • Pinta

    A simplified alternative to GIMP and modelled after the popular Windows program Paint.Net, Pinta is good for average users and includes most basic features including common drawing tools, resizing and cropping, adjustments and effects for tweaking images as well as supports for multiple layers.

Best Free Vector Graphics Editor for Linux
  • Inkscape

    "A top product enhanced by an excellent user interface and the impressive set of tutorials, helps wean the user away from the world of digital images to the nodes, lines, curves and shapes that form the basis of vector editing." (Review)

 

Best Free Digital Image Stitcher for Linux
  • Hugin

    A GUI front-end of Panorama Tools allows you to stitch overlapping digital photos taken from the same location into a complete panorama, with advanced features and workflow options such as correction of exposure and white balance, generate HDR, supporting a full range of cameras and lenses, multiple rows of photos, cropping, masking, control points, optimizer and more.

You can start simple with just the bare walls or import an image of your intended floor plan to serve as a basis for the design-to-be.

    The user interface is as intuitive as it gets; drag and drop furnishings from the built-in catalog onto your floor plan. Clear graphic handles then make it easy to edit the items. Once you've finished your home design and tweaked every niche and corner to your liking, the fun has only just begun." (Review)

  • BlenderBlender

    "A complete software package for 3D modeling, texturing, rendering, animation and physics. It has a complex but merciful user interface, and the entire repertoire of its capabilities are made available through a scripting language, so the creation of 3D games beckons.

    The software can import from and export to more than 20 different file formats. There is a large and growing community of Blender users who've already contributed numerous add-on scripts that can make your going easier. If it can be imagined then it can be realized, with Blender freeware." (Review)
