Digital Photography




Digital Photography

Digital photography can be broken down into three main areas. Firstly, the input stage requires capturing a digital image through either a digital camera or other device such as a film or flatbed scanner. The next stage is the edit stage in which the digital images from the input devices are transferred to a computer for image manipulation or adjustments such as correcting red eye or color casts. The final stage involves outputting the image on a printer of which there are three main types: inkjet, laser and dye sublimation. New technology such as smartphones, tablet PCs and hd video are also part of this process.

Another aspect to consider with regards to digital photography is storage. Memory cards have increased in capacity & have fallen in price in recent years but file sizes have also increased with 20 megapixel cameras becoming widely available. Fortunately for long term storage, there are various back up devices available including internal & external hard disks, blu ray, CD & DVD writers and cloud online server storage services.
