Modeling Contemporary Billboards in Photoshop

[P5se Camelback]

For a true artist's fixative, try the Grumbacher brand ... available at most art supply houses. If you can't find any locally, try Dick Blick, a professional art supply house, or it can also be procurred through Amazon -- Good God! They seem to have EVERYTHING!

Anyway, as I recall, it fixes everything (charcoal, pastels, and pencil work, and is indicated as appropriate for use on paper, photographs and printed materials,) which should include things printed on a printer ... just make sure the ink is set well (totally dry) before hitting it with fixative. And, just as with spraying paint, with fixative several light coats, allowing a few seconds drying/setting time between coats are better than one heavy coat!

For those unsure about it, there's nothing to fear ... but this tutorial should eliminate any worrys about its application.

[Note: You don't need an easel, but just placing your subject on a near-vertical board is good
insurance against the possibility of an large errant drop falling on your work by accident.]
