Animation Using The .gif Format

[To be clear, I use the term "format" to mean the type of code used to record the information. I use "file" to mean the storage of the format.]

Invented by CompuServe, the Graphic Interface Format was designed to show simple animation. There was once a patent problem with the format. The patent has expired, and is no longer an issue.

All web browsers can view a .gif file. The .gif animation can be repeated forever or set to a specific number. Aside from that, it is like a cartoon. Some web browsers allow the user to not show animation.

Panoramic Photographs

The word is "panorama" from "pano" meaning "all" in Greek, plus "rama" meaning sight in Greek. It is "pano" and not "pana." It is now used to describe images that include more than 90 degrees of view.

The first trick in making a panoramic photo is to take several shots with a slight overlap of view. (Even 10% overlap is enough.) To avoid added distortion, try to rotate the camera at the lens and not the base. Then you need to meld the images together.

Infrared Photography: Exploding the Myth

There has always been an air of mystery about infra red photography. Perhaps justified in the days of film but wholly unwarranted now that digital cameras have made things so much easier.

That which we call light expands on wavelengths to each side of what the human eye can register. Light on the shorter wavelength is Ultra Violet and on the longer wavelength Infra Red.

Five Steps to Getting Started with Twitter, for Organizations

Twitter: A Brief Overview

Twitter is a service that allows people to communicate in very short messages, which are known as Tweets. (Both "Twitter" and "Tweet" are trademarks of Twitter, Inc.) Tweets are limited to 140 characters, including letters, numbers, spaces, punctuation, and so forth. Tweets can be sent from, and displayed on, the Twitter Web site directly, as well as on mobile phones and many other interfaces. The limitation to 140 characters arises from the origins of Twitter as a way to use SMS text messaging on mobile phones as a way to send and receive Tweets.

Raster vs Vector Graphics

Note: The following was originally part of an email discussion with photographer Emily Roesly regarding using photos from the Free Photos archive for creating vector graphics. The message was edited to share here the discussion of raster versus vector graphics as well as "autotracing" images.

Seven CMS Benefits for Site Management

This article provides an overview of seven important benefits of using a Content Management System (CMS) for managing a Web site.

In summary, CMS benefits include:

  1. Consistency of appearance
  2. Ease of adding content
  3. Ease and low cost of adding features
  4. Rapid yet thorough site-wide changes
  5. Ease of "repurposing" (using existing content for new purposes)
  6. Ease of dividing work among team members
  7. Ease of adding user accounts and features limited to authenticated users

In a bit more detail, respectively:

Three Bad Myths of Email

An article about email might seem to be out of place in a library about audio, video, and multimedia, but email often plays a role in "new media" content. For example, a Web site may offer a "send this page to a friend" function. Or, new user registration on a site may initiate an email notification to the site owner. Thus, although it is not normally considered "multimedia," the role of email in new media content earns a place for this article in the AVM Library!

Six Steps Toward Better Data Privacy

You already know that digital media offers many benefits. For example, consider the old process of sending a standard-definition VHS tape through postal mail to a client, compared to the ease of posting HD video content onto a site like YouTube and sharing it via email and social networks. With such a vast improvement in speed, flexibility, cost, resource usage, and quality, it might seem there is no negative side to the newer process.
