Image Standards and Photography

Image Standards:
Images should be used at 100% of their size at 72 dpi for best loading time for the page.

JPEG:
The better format for posting photography online. JPEG images can contain millions of colors and can be compressed to your desired size. We recommend:
Photoshop Quality level 80 — small images
Photoshop Quality level 60 — large images

GIF:
Generally used for non-photographic images of 256 colors or less, such as buttons, icons and arrows.

Photography:
When using photography, make sure to follow copyright regulations. When appropriate, give credit to photographers.

The images owned by Clemson University may be used on Clemson University Web sites. Photos are available for download from Photo Services . If you need further photography assistance, you may contact Creative Services or fill out the request form for Photo Services.

Video Podcasts

Recommendations for Formatting Video Podcasts:

If you’re encoding your video podcast at 320×240, please increase the resolution to either 640×480 or 640×360 (depending on the aspect ratio of your source files). Why? Because video podcasts at this resolution look great on Apple TV and still port to video iPods. Lower resolution podcasts might also work on both platforms, but they don’t look nearly as good on a widescreen TV. As always, make sure to test any encoding changes you make to ensure device compatibility. QuickTime 7.1’s “Export to iPod” function will ensure that a video file is encoded at a width of 640 and is iPod-compatible.

It’s best not to create two different podcast feeds for different resolutions. By doing so, you dilute the popularity of your podcast and reduce exposure in our charts. It’s better to have one feed high in the charts than two that are lower.

If your source files are 16:9, stick with that aspect ratio. Don’t add letterboxing to make them 4:3. By doing so, you prevent the video from expanding to fill a 16:9 widescreen TV and instead end up with black space on all four sides. Also, your original source files should be at least 640 pixels wide.

Of course these are just recommendations. We understand that there are good reasons for 320×240 (bandwidth bills) and 720p (looks fantastic).

Do whatever makes the most sense for your show. For more information on formatting video, see the recently updated spec: http://www.apple.com/itunes/store/podcaststechspecs.html
