What’s PhotoMetaData? What’s an Alt Tag?

Camera Canon EOS 7D
Exposure 0.003 sec (1/400)
Aperture f/5.6
Focal Length 700 mm
ISO Speed 400
Exposure Bias 0 EV
(Above) Typical photometadata that is included with each of the camera’s images. This data (information) is embedded in each picture with the snap of the shutter. Such image data is useless to most photo researchers. Caption text can be included in the interior of the image also, but like the photometadata above, it cannot be seen or retrieved by search engines.
If you want photo researchers to find your photos, your photo descriptions have to be embedded in the exterior of the photo as an “alt tag”. Check YouTube to learn how to make Alt Tags for your photos. Alt tags will also help your search engine ranking if you pursue a stock photo specialization. –RE
