On September 23, 1930, the first commercially available photoflash bulb was patented by German, Johannes Ostermeier. These flashbulbs were named the Vacublitz.

Today’s cameras are more advanced and sophisticated than ever with such things as their small compact size and LCD screens to preview the pictures taken. The size and quality of images have increased drastically with some of the top brand cameras being rated with as much as 6.5 megapixels or 6.5 million pixels. Instead of rolls of film that the pictures are stored on until you get them developed today’s cameras have memory sticks or memory cards. These memory cards can store hundreds of pictures on one small card. The quality of the pictures can be adjusted but with quality comes more storage space being used. To transfer pictures over to the computer most cameras come with a USB link which allows high speed downloads to the computer from the camera. The cameras of the future can only be expected to get bigger and be...
