How To Effectively Use Images, Audio, and Video
Monday, January 29th, 2007You can draw attention to your online communications and get your message across more effectively if you add images, audio, and video to your documents, presentations, and web site. Here’s how you can do that:
Working with Images - Hire a graphic designer to create a logo for your business, stationery templates (print and online), and slick web pages. Use a stock photo agency like iStockphoto to obtain images that illustrate your message clearly on web pages and presentations. Use your own digital camer to take pictures for your business image library, to save on stock photo licensing fees. You can also use Google Image Search to find images on the Internet, but beware of copyright and licensing issues. For websites, use your webhosting account or a free image hosting service to store the images you use – it constitutes bad manners to include an image hosted from someone else’s server without permission. For editing images, you can use Paint.Net or The GIMP to edit your images on a budget, but I highly recommend Adobe Photoshop Elements for casual image users, and Adobe Photoshop (the original, full featured program) if you use graphics extensively.
Remember that images for use on the web should be relatively small - the typical size for a web photo is 640×480 in pixels, set at 72 dots per inch (approximately 6 1/3″ x 9″ on a computer screen). Images for printing need to be very large - an 8″x10″ photo should have at least 150 dots per inch, which requires a 1200 x 1500 pixel source image, and professional printing with photo quality is usually set at 300dpi, requiring 2400 x 3000 pixel images (more than six megapixels). Since you can always size an image down with no quality loss, make sure that the images you use are as large as possible if you think you’ll need an image for both online display and print use.
Working with Audio - You can use an audio mastering program to take any input - including a microphone plugged into your computer’s sound card, or a digital voice recorder’s WAV/MP3 files transferred over USB - and make an audio program from it. You can also use your CDs or purchased music online to create soundtracks for your offline presentations. Right now, the big thing in online audio is the podcast. Anyone can make a regularly-scheduled audio program using RSS and uploaded sound clips. Perhaps you can use a podcast to draw listeners to your business and get your message out there.
Take major caution, however, in obtaining explicit permission in using audio files in your work, especially for music distributed by major record labels. Licenses are required for online distribution of music (separate from the license you receive when you buy music for typical personal use) and the record industry’s official group organization (the RIAA) has come down hard on people who are not careful with work written by or performed by their artists. Original work is generally okay for use if you purchased or obtained permission from both the original songwriter(s) and the performing artists. If you don’t know much about copyrights, I’d advise that you avoid publishing anything online that you did not create yourself from scratch.
Working with Video - You can use video clips to really capture your audience’s attention, both in presentations and on the web. And just like podcasts, vlogs (short for videologs) are regularly-produced programs that have gained a lot of attention on the web in recent months. Video can often be downloaded from a late-model digital camcorder to a computer using a transfer cable or a DVD-ROM (check your camcorder’s instructions - older camcorders that record on non-digital tapes are unfortunately unable to do this). Even mobile phones and pocket digicams, if they have recording features, can be used to record video for the web! Many video-sharing services online can host your video and share it with millions of people, plus provide code snippets to insert into your web pages so that the video can play directly in your own website. YouTube is the most famous of the video sharing services, or you can use Veoh or Vimeo if you prefer. Again, copyright violations are pursued aggressively online, so make sure to get the copyright owner’s permission before using any recorded clips that you have not produced yourself.
