Learning the basics of graphic design, image/photo editing

Here’s the spot for documenting terminology and other information re: basic image editing. A longtime webmaster with generalized skills, I never did learn as much as I wanted about photo editing and graphic design. One of the stumbling blocks for newbies in the area of image editing is the terminology used in this field.

Although Photoshop is the industry’s gold standard, we use GIMP. It appears the best path — by far — for this graphics design beginner would be to go through all of the GIMP tutorials, starting with the beginner level.

After giving this a little more thought, IMHO it’s pretty clear that the best way forward for graphic design, image editing, photo editing beginners is to:

  1. Decide which graphics software you’ll be using most often
  2. Find and study web-based tutorials for the current version of your graphics software

Precious time would be better spent following an organized set of tutorials rather than learning a bit here and a bit there. However, if all one wants or needs to accomplish only a limited set of basic image editing processes — like cropping, resizing, scaling, modifying the canvas size, etc. — then you’ve got it made. These basics are a breeze with GIMP and probably eight dozen other graphic design software/freeware programs. GIMP has a tutorial just for these routine image editing needs: GIMPlite Quickies.

Terminology

Lanczos resampling – Wikipedia — Highly technical stuff; but basically, this is a process or tool designed to remove the ugly pixelation that occurs in some kinds of JPG image files – especially around text and such.

Stack Exchange: A network of helpful Q&A sites

Stack Exchange network of helpful Q&A sites During research for an article last month, I found a unique site worth noting for future reference: English Language & Usage is a site based completely on questions, most with valid answers, posed by writers and others who care about accurate, proper writing…

The English Language and Usage Stack Exchange is for linguists, etymologists, and (serious) English language enthusiasts.

Stack Exchange network of helpful Q&A sites Reading further, I saw that this English Language and Usage website was but one site in a network of more than 60 sites collectively known as the Stack Exchange Network, all of which are Q&A (question-and-answer) sites, covering a wide range of subjects.

An idea hatched…

Jeff Atwood and Joel Spolsky created a site called Stack Overflow in 2008 and eventually brought together millions of computer programmers from around the globe to help each other out by documenting the answers to a wide range of detailed technical computer questions.

The amazing success of Stack Overflow led to a $6 million venture capital investment from Union Square Ventures, enabling them to create and launch the Stack Exchange Network and started launching a collection of Q&A sites in August of 2010.

As of January 2011 there were 63 separate sites in the Stack Exchange Network with over 19 million unique visitors and counting. (Source: About Stack Exchange)

The best GIMP plugins for photography

Trick your photo editing, retouching with these GIMP extensions

GIMP graphic design open-source software logo on a brown grocery sack 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.

GIMP - great for photo editing, open source software
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.

Blue Sky Gradient – Great for adding a blue sky gradient to burned-out or white skies; use threshold mask; see also the Guide to Using Blue Sky

Blue Sky & Clouds – Similar to Blue Sky Gradient (above); see also the Guide to using Blue Sky & Clouds

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.

Midnight Sepia Script – Implements midnight sepia effect; see also more info, examples, discussion

GIMP - great for photo editing, open source software
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

Image Subdivide – Subdivide the image in M Rows x N Columns and save any rectangular portion in the new files; see also the subdivide tutorial (in Italian, but Google will translate it for you)

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.
