A high definition (HD) photo is a shooting mode found on digital cameras that produces larger, wider, clearer, and crisper images because of increased pixels. High definition images must have at least 720 pixels or greater to be in the HD category and 1080 progressive movement to minimize blurs. The image will typically fit a wide-screen HDTV. HD photos may also be available to video record on some digital cameras as well. Examples of high definition content includes terrestrial broadcast, direct broadcast satellite, digital cable, high definition disc, digital cameras, internet downloads, and video game consoles.
To view high definition images, you’ll need both a high definition source and monitor, which can either be a television or computer monitor. Most digital cameras with a high definition mode will offer an optional component cable to connect directly to the HDTV.
High resolution photos
A high resolution photo is an image with more pixels per inch (ppi), which creates a higher quality photograph. Pictures become stretched and grainy when they have lower resolutions but are crisp and clear with high resolution. A standard image resolution for printing tends to fall around 600 ppi. Always shoot for the highest resolution to create the best image possible. Higher resolution photos also make for easier editing since the photo editor is deleting pixels rather than creating them. Images for the web tend to require a lower ppi, but it depends on the type of device you’re working on. Resolution varies depending on the definition but a good rule of thumb is the larger the screen, the worse the quality.
