Digital cameras use light sensitive sensor and store image data on storage medium digitally. Analogue cameras use light sensitive medium to store image data.

What is SLR camera? – SLR is single lens reflect camera. SLR cameras use light sensitive medium to store image data.

What is DSLR camera? - DSLR camera is digital single lens reflect camera. DSLR camera stores image data digitally.

What is MP? – If a digital camera has 5 Mega pixels then it means that such camera can save image data about 5 million pixels. The more pixels your camera can record, the more little dots/pixels you have in your digital photos.

What is pixel? – Pixel is one dot in a digital photo. Every digital photo consists of many pixels. The more pixels you have the bigger picture you have. If you have more pixels, you can print bigger picture.

What is MB? – Megabytes are used to count data that is being stored digitally when taking photos. Every digital camera can save some amount of image data on a memory card or in a camera memory. One 512 MB memory card can store approximately 200 photos, made with 10MP camera.

1MB = 1024 Kilobytes

1KB = 1024 Bytes

1 Byte consists of 8 bits.

Image size – the actual image size depends on camera settings and lighting conditions too. You can set image quality to higher or lower in most cameras. I would recommend using higher image quality because it is impossible to turn back the time ;)

Photo camera - It is easier to divide photo cameras into four bigger groups.

1. Analogue cameras

2. Digital cameras

3. SLR cameras, (single lens reflect camera, uses light sensitive medium to store image data)

4. Digital SLR cameras, (digital single lens reflect camera, stores image data digitally,)
