Remarkable Use of GIMP and G'MIC

June 11, 2017

The other day I received an email asking me a question about brushes (specifically mypaint brushes) in GIMP. The innocuous question led to an interesting discussion with an artist who has been using GIMP and G'MIC for quite sometime. Meet Greg FitzPatrick, artist who is fluent in Swedish and English and has been doing all kinds of nifty stuff with GIMP and G'MIC. Greg told me, "I usually spend an hour or two in Gimp with each shot layering up G'mic's various filterings. I vary input resolutions -- low resolutions create more effects with the filters. I got David T to create a filter that uses multiple scalings for various effects. (multiscale)". That would be David Tschumperle the creator of G'MIC. He further added, "I usually export around 10 variations of a piece from Gimp, wait a few days and then chose my favorite. I do final touch-ups in Artrage which has some nice palette knife tools, as well as some other features that I have never found in Gimp/g'mic."

No, the above is not that remarkable. The beautiful part of this story is that, the above artwork was sold at the Hunger Project exhibition. The above artwork raised US $2000 for the project. That to me is the most remarkable part of this story. Here we have an artist using FOSS tools to create artwork that is then used to raise money for a most worthy cause. Hats off, Mr. FitzPatrick.

The image above was by no means easy to create but satisfying. As Greg observes, "At the moment I am printing on plywood with UV which is difficult because UV printers more often than not have banding problem and you have to find really nice quality birch plywood. but you can imagine that the waves in the Louisiana picture go nicely with the grain texture of the plywood."

GIMP and McGimp 2.9.5 Standard Edition

GIMP 2.9.5-std with Nik HDR Pro 2 The standard edition has been updated to the latest pull from two days ago. A new function has been introduced where one is able to register more than one variant per MIME type. What this means in particular is that you can choose your own camera raw image convertor from the preferences. Of course, the plugin provided by the author(s) has to register with GIMP to be able to take advantage of this functionality. Currently nufraw is already registered as the default raw editor in my builds. In the future you should be able to choose a default raw convertor. This would be through Preferences . GIMP 2.9.5-std with Preferences Menu

However, you may want to consider a workflow where you process your RAW images with a standalone RAW editor such as RawTherapee or Photoflow, and then send to GIMP/McGimp.

G'MIC version has also been updated to work with this version. You can follow G'MIC on G+.

High-Resolution Monitors and Windows 10

This version of GIMP should be safe on your high-resolution monitor. The screenshot above is from a 4K 17-inch laptop. GIMP is perfectly usable on this laptop. To achieve this, the regular version installer adds a registry item that allows Windows to manage non-dpi-aware applications. The portable version does not interact with the registry and so will not be dpi-managed. If you have a higher than 2K laptop and the application looks too small for you, then the registry will have to be modified to allow the portable version to be dpi-managed by Windows.

Please email if you have questions, concerns or comments. Thanks.

PANORAMA STITCHER

How to stitch panoramic images

I have added another plugin that allows you to stich large panoramas from within GIMP. To do this you will need to get the free Panorama Stitcher from the App Store on your Mac and install it in your Applications folder.

It is important to remember that the images need to be loaded as layers. Once done, start the panorama stitcher from the filters menu, and you are good to go. Once the panorama is created, you must save the file in the default location (your Documents folder) and close the stitcher. The panorama will now open in a separate window for further editing.

Please watch the video.

On Windows, please download and install the capable panorama stitcher available free of charge from Microsoft. Install it in its default location C:\Program Files\Microsoft Research\Image Composite Editor. Once installed, you'll be able to use the panorama stitcher on Windows.

Helpful Hints

  • General Installation Instructions
    Windows

    Important: Uninstall previous builds from the target installation location. Installation has been streamlined as much as possible.

    Download and double-click on the installer and follow the instructions on your screen. Your computer may ask you to provide your administrative password. This is normal while installing software on the target computer. The software will be installed in the Program Files folder if you select the default settings. Also, it will create necessary files and folders.

    The portable versions do not require any particular installation instructions. Simply double-click on the executable and unzip it to your desired location. The portable versions are self-contained and do not interact with your system or any existing GIMP installations.

    File Association

    Remove all references to the software you are installing from the registry and then use Windows to associate this version with your desired image formats.

    Mac OS

    These versions are compatible with Lion and above. Simply unzip the version you prefer and drag it to you Applications folder.

  • About Virus Alerts

    My builds are based on source code from the respective developers. Some modifications have been made to make the code compatible with Windows. These builds are compiled using GCC 6.2.0 available from the great folks at MinGW. I have received reports that some virus checkers are triggered by my builds. There is not much that can be done with these reports. They are false positives that you will have to take up with your virus checker software company. Please read this interesting article on how frustrating these reports can be.
