Images can be as simple as pictures taken of nearby buildings or walls and then scaled appropriately. A composite image can also be assembled with graphics software in combination with stock photos, textures, fonts, and visual elements from a variety of sources. Public domain images can be found online, and many commercial image or texture collections are available.
A web search will turn up many sources for free textures and images. Many sites are marked as having 'dangerous downloads' which is something to keep in mind... Available images were often low resolution, distorted, or skewed at an angle. Color quality was sometimes poor with some, or all, of the image washed-out. Tileable versions were rare. Many images were also incomplete, lacking edges for example.
Commercially available images and collections
A wide selection of images and textures are available from various online sources. Texturama offers building pictures as well as architectural textures and individual images that can be purchased. A hobby version of their collection is available, from which selected elements were used in combination with personal photos to create graphic details incorporated into my modules. Sources for textures and images that may be of interest include:
A variety of fonts and logos associated with railways are available. These can be used on railroad signage and rolling stock to bring a sense of historic realism to the layout.
Original images and textures
With a decent camera and some determination, one can create quality custom images. Shown are a few developed using photos taken during a trip to Manhattan. Pictures were taken with a Canon EOS 20D camera, manipulated with Adobe® Photoshop® Elements 2.0, and corrected for lens distortion using the PTLens plugin from ePaperPress. Additional details outlining one method for manipulating images to generate a straight-on front view follows...
Creating custom images from photos
A number of resources and instructions can be found online. Above are the basic steps involved using one of my building photos as an example.
Applying Custom Images
3M Super 77™ spray adhesive works really well for affixing custom images to wood blocks and train cars. Coat both surfaces for a really strong bond. For crisp, clean building lines - use a black or warm gray permanent flowpen on the edge of the photo to darken the exposed white paper edge. Paste the building front and one side first. Then sand the opposite side and back face to the final dimensions. Glue the remaining side and back and then sand the top and base flush. Attach a roof image or sloped roof on top to finish the building. Touch up any remaining white spots with your black pen and then varnish the building to protect it and remove the photographic sheen.
