Got an image problem? Start with better digital images.

There’s no better—or worse—way to convey your company’s message than with an image. It is your image. It is true that professionals must be involved creating your corporate identity or advertising campaigns, but you can take the task of preparing images to include in your interactive stuff.

Joe Smith, art & code guy with Art Dude™ Creative, will guide us through the basics of pixels, resolutions and color. We will crack open some images, learn their structures, manipulate their attributes, observe their aesthetics, determine their thousand words (in every picture), optimize their algorithms (not as geeky as it sounds), and avoid internet image pitfalls. Time and interests allowing, we can delve into more advanced topics like masking, using text in an image, special effects, or color correction.
