I have been doing a series of articles about line art. In my first article, I spoke about how to use the graphics editing software to convert a photo into line art. The second article gave you a list of programs and techinques that would save you literally hundreds of dollars in licensing fees while simultaneously giving you the power of professional graphics programs. Now, I would like to show you step by step how I used the GIMP to create a line art drawing of my grandparents.

First, as I took the portrait and scanned it, creating a digited version. To do this, I selected TWAIN from the GIMP menu (File…Acquire).

After the picture was scanned, I used Vidar Madsen’s method described in the GIMPy high pass filter sketch effect tutorial. Vidar shows you how to use the gaussian blur filter, merge opacity, desaturate the colors, then clean up the lines using desaturation. The results were ok, but nothing to write home about. I found a Photoshop plugin called Cleanup which might have made it more useable; however, I could not get it to work with the GIMP.

Next, decided to start from scratch and try to render the line art by hand by “tracing” it from the photo. Melissa Clifton wrote an excellent tutorial about this technique on her website. I created a blank layer (Layer…Duplicate Layer), set the opacity at 50% (Dialogs…Layer…Opacity slider bar), and started drawing using mostly the pencil brush to draw the graphic. Once the drawing was done, I had a little fun and colored it in, making look as though it came from a graphic novel.

I wasn’t happy with the initial results because the details of the face were very unrefined. For example, in my initial drawing, Pa looked like he had alien eyes, and his mouth was all wrong. Granny’s eyes were roughly drawn as well. To fix it, I erase the insides of the faces and started over again. The second time, I experimented with different brushes. For example, I found the pressure brush with a medium or small splatter point worked best for the details. I also took my time. The first go around, I finished in a couple of nights, but when I started over again, I went took approximately a month just to redo the faces. It was worth the wait, though, as I am much more pleased with the results.

All in all, I would consider this a pleasant experience. When I was very little, I remember sitting on my grandparents’ laps, touching their faces and looking into their eyes. Nothing short of having them back could replace that memory, but this was the next best thing. Staring at the photograph, I was able to capture all of the lines of wisdom, all of the smiles, all of the worries, all of the love that gave charactor to two people who will forever hold a special place in my heart.

Now, go enjoy your family and make the world a better place by working on some photo family memories of your own.

Have you ever thought about what you could do with your photographs? There are so many possibilities. For example, you could reduce down your photo to black and white, color it in, add a few thought bubbles and make your own comic strip. Or, you could create a clay caricature of the subject of your photo. You could transfer the image onto a square block of fabric and sew it into a heirloom quilt. You could turn it into a wood plaque carved with a scroll saw or a table top make with marquetry inlay techniques. You could create a 3D hologram, Warhol style pop-art print, or ascii art poster. Or you could turn your photo into a wire sculpture, ceramic mosaic or etched glass goblet. The possibilities are endless.

A key step in producing many of these object’s d art is to reduce the photograph down to a black and white line drawing. Graphic editing programs, such as Adobe’s Photoshop, provides automated ways to do this; however, unless you’re willing to drop $700 for a legal copy of Photoshop, you may think you are out of luck. The truth is, you can achieve most of the same effects, including the photo-to-sketch function, using the GNU Image Manipulation program, or GIMP. With GIMP, you can manipulate colors, reduce noise, selectively cut and paste objects within a photograph, work in layers, shrink or enlarge your image, and export your photo in a variety of file formats. GIMP even runs most Photoshop functions. Combine GIMP with other free software, like ImageMagick, a tool that lets you quickly manipulate graphics files, and Inkscape, which lets you convert to/from vector graphics formats, and you have a fully functioning graphics suite.

You can find tutorials on GIMP.org detailing how to turn a photo into a sketch. The resulting sketch is, in my opinion, very busy when this method. A similar method on Spoono.com produces cleaner results, though still too many lines for my taste. I prefer to use the method described by Vidar Madsen in his GIMPy high pass filter sketch effect tutorial. Using this method produces a drawing that is clean and simple, though I have to admit that sometimes, I prefer the old fashioned way…I fire up GIMP, create a blank layer and trace my image to create the line art.

Depending upon your project, I am sure that all of these methods will produce satisfactory results for you. Give them a try and let me know what you think.

Until next time,

In my last article about producing line art to use in your photo projects, I introduced you to the suite of programs that I use in my photographic endeavors, namely, the GNU Image Manipulation Program, or GIMP as it is more commonly known, Inkscape, a vector graphics program, and ImageMagick, an all around grapic toolkit with many uses. Both GIMP and ImageMagick can be used ran in batch from the command line.

One of my readers suggested that I provide a resource list to help my subscribers obtain and learn how to use those programs, so here it is.

One of my goals is to help inspire you to transform your photos into objects of art that can be displayed and enjoyed every day. To that end, I would like to present a video that I found on YouTube of someone who took the picture of a little girl and transformed it into a work of art - drawn in CRAYONS!!! Too cool!
Check it out!
