Question about Sony Mavica MVC-CD300 Digital Camera
Posted by Anonymous on
The camera is not megabytes (MB) but megapixel (MP), there is a big difference. If you multiply the horizontal resolution by the vertical resolution then that will be how many megapixels are being captured. So in this case, max resolution 2048 x 1536 = 3145728 which is 3.1 MP effective. I don't think any camera actually captures exactly the full MP listed on the camera. Now, if each pixel was represented by a byte then you would have 3.1 MegaByte picture captured. However, each pixel is represented by I think 3 bytes which would give you a 9.3 Megabyte picture captured. However, since this is usually to large for most users to deal with, compression is introduced thus the settings for fine and standard. The tiff picture type is the 9.3 Megabyte photo with no compression. For most of us this isn't very effective for working with so we use the jpg compression. This reduces the picture to a more manageable size for saving, manipulation and storing. Keep in mind that this is what is called a 'lossy' compression which means that it actually removes pixels from the photograph and uses a technique called interpolation to bring the pixels back later.
