Nowadays, most educational institutions are putting more content online and with this the need for digital material to support that Web-based content is growing rapidly.

Dr. Ronny Richardson, of the  Southern Polytechnic State University, Georgia has made a review of products that can be of use for teaching professionals. Two models of the Gateway cameras went under his close scrutiny to determine its individual merits.

First model to be examined was the Gateway DC-M42. This camera has a 4.1-megapixel resolution with an 11MB internal memory limiting the user to just 9 images storage at maximum resolution. You will need to either download the images or burn them to a CD since the unit do not have a memory card provided. The better model would be the DC-T50 which boasts of a 5-megapixel resolution selling at a very affordable price of $250. The DC-T50 has a 32 MB SD memory card included that can carry up to 12 images at maximum resolution. Both cameras can take great pictures at their highest resolutions but there is no doubt that the DC-T50 is the better choice taking into consideration their prices as well.

File Storage

Your camera stores information called EXIF data within each of your photographs. EXIF stands for Exchangeable Image File: the file format used by most digital cameras. For example, when a typical camera is set to record a JPEG, it’s actually recording an EXIF file that uses JPEG compression to compress the photo data within the file. Data from and EXIF includes the file name, photo dimensions and size, exposure and ISO information, as well as camera brand and mode. To view said file you will need and EXIF Image Viewer. This is a free software and. It displays EXIF information for all JPEG files in a folder.

The digital age has brought about exciting new products and services that make digital imaging easy and user-friendly. Freeware and information are readily available on the web to help digital enthusiasts know more about new developments in the field of digital imaging.
