Trick your photo editing, retouching with these GIMP extensions
Why pay hundreds of dollars for PhotoShop when you can get something just as powerful at no cost? Well, there probably are a few arguably legitimate reasons… Adobe PhotoShop is certainly the golden standard in graphic design. However, the longer I use the GIMP to handle my graphic arts needs, digital photo editing, logo experimentation, and so forth, the more impressed I am with this very capable open source software. As impressive and powerful as the GIMP’s default installation is, GIMP users can find and install dozens or even hundreds of plugins – each of which adds a bit of new capability to the graphic design software. There are even plugins which allow GIMP to behave more like Photoshop.
Here are some of the more popular GIMP plugins that are well-suited for the process of editing photos and retouching your digital photography. That’s right: one can photoshop with the GIMP as well as one can photoshop a person into a picture with Photoshop.
Antique Photo Border – Simulates a yellowed, slightly jagged border recalling those of old photography; after copying it into GIMP’s
scripts folder, you will find the plugin via
Filters -> Decor -> Antique Photo Border.
G’MIC: GREYC’s Magic Image Converter – proposes a set of various filters to apply on your images, including artistic effects, image denoising and enhancement algorithms, 3D renderers, etc; this large plug-in integrates many different effects.
Wavelet Denoise – The wavelet denoise plugin is a tool to reduce noise in each channel of an image separately. The default colour space to do denoising is YCbCr which has the advantage that chroma noise can be reduced without affecting image details. Denoising in CIELAB (L*a*b*) or RGB is available as an option. The user interface allows colour mode and preview channel selection. The denoising threshold can be set for each colour channel independently.
National Geographic – This script simulates a high quality (portrait) photo like these from the National Geographic; after copying it into the GIMP
scripts folder, you will find it under
Filters -> Generic -> National Geographic.
Liquid Rescale – This plugin aims to resize pictures non-uniformly while preserving their features so as to avoid distortion of the important aspects; see also the official Liquid Rescale page, a Liquid Rescale video, and the Liquid Rescale Library
Split tone – Uses one color for highlights and another for shadows; similar to (same as?) sepia tone
3D Screenshot – Turn a boring ol’ flat image into a stylish 3D-shadowed-glowing photo
Pseudo Tone Fixer (landscape tone fixer) – This script tries to fix the tone of a photo taken with wrong exposure; in some nature or landscape photos, this will nicely enhancing the colors; the general idea is to produce different copies of the image at different gamma levels, then applying simple tone mapping techniques to produce a vibrant photo.
Interpolation Plugin – Works by doing plane/curve fitting and calculating weighted averages; takes samples from a grid of pixels from ‘known’ image areas, attempts to fit a plane or a curve to each, then uses those samples to estimate the ‘unknown’ image areas. NOTE: Gets rid of spots and other things that perhaps shouldn’t be there.
