Tutorials at The Cartographers’ Guild

I am a frequent contributor to the forums at The Cartographers’ Guild. In the course of my time there, I have written several tutorials and guides. Here is a complete list:

Creating a local-scale tree texture in Photoshop
This tutorial was adapted from a technique at the Cartotalk forums, but the original was very difficult to understand. I clarified it and provided illustrations.

An Introduction to Image Export Formats
Many beginning artists have never learned the differences between the various image formats available to them and sometimes pick a final filetype that is suboptimal in terms of compression ratio or visual quality. Here, I have attempted to provide information about all of the common formats and when to use each one.

Using Channels to Separate an Object from its Background in Photoshop
I see a lot of inexperienced artists try to cut an object off of its background by painting a mask, using the pen tool, or even the eraser! This is a much easier method that aims to preserve the detail of the subject’s edges. Also, since it does not rely on hand-painting, it can be used on video footage. It is, in fact, the basis behind the process of chroma keying.

Using Photoshop’s Clone Stamp tool for better brush work
Many cartographers use brushes to put down mountains and trees, but anywhere the brush strokes overlap, the “white” parts are revealed to be transparent. The Clone Stamp tool, while not as elegant as the Brush tool, can be used to counteract this behavior.

Essential River Guidelines for Mapping
The Cartographers’ Guild has a small cadre of self-styled “River Police” who examine maps for unrealistic water behavior. This guide collects their wisdom into a single place and cross-indexes other river-related discussions.

The Ruined Valley

My Visual Effects Field Production class is attempting to recreate several shots from the trailer of The Mutant Chronicles. (Great trailer, lousy movie.) This is a photographic composite intended to replace this shot:

And my version (Click to enlarge):

The night sky, some of the midground mountains, the refinery, and the rocky arch were provided by cgtextures.com and are used in accordance with that site’s license.
The bridges were provided by the National Oceanic and Atmospheric Administration. Original photo entitled “Bixby Canyon Bridge” by Cpt Albert E Theberg, NOAA Corps (Ret) is in the public domain.
I photographed all the other elements myself along the Peak to Peak Scenic Highway between Blackhawk and Estes Park, CO.

Looks like YouTube nixed the trailer for a Terms of Use violation. Too violent, I guess, though it really wasn’t even as bloody as an episode of CSI, in my opinion.

“Deadlines” photomanipulation

Figuring out how to make the melted wax was a fun experiment. Here’s how it’s done:

Make a new layer above the candle. Edit > Fill > 50% Gray.

Set the new layer to the Overlay blend mode, add a layer mask, and fill the mask with black.

Activate the Bevel & Emboss Layer Style. Leave the defaults for now; they can be adjusted later.

With a large, hard-edged brush, paint white on the layer mask. The bevel will appear wherever you paint, but because the layer is set to Overlay, the gray is invisible—only the light and shadow appear.

Now adjust the bevel to taste.

Underwater Matte Painting

A matte painting is often used in film and television when the characters are in an environment that is either fantastic or somehow impossible to shoot. “Painting” is a misnomer, though, as modern matte paintings are typically composites of photographs, giving them much greater versimilitude than the old backdrops used, for example, in Star Trek.

I am eager to try another of these, as I think I can do it much better, especially if I photograph my own assets.

Jungle Ape

I had something of a hard time with my Advanced Image Manipulation class. I just didn’t “get” many of the assignments. This one was fun, though I could have done better if I’d given it the time it deserved. I really wish I’d had a pic of a gorilla actually in the jungle.

Photoshop Colorization

I liked the composition of this photograph, but the camera’s autofocus liked the girls in the background more than Mike. I colorized the image and put a big blur on the background to try to make Mike the focal point. Obviously, taking the picture right in the first place is better than fixing it in Photoshop.
