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 ;)
