Add pixels on NEF arquives, Nikon D90

[EBarros]

Hello! I need to know how many pixels can add to a RAW file. I have a Nikon D90 camera, which uses the term "NEF" for RAW files. I need to make enlargements of my photos, but I need to know how much it is possible to add pixels!

You do not actually "add" pixels, but you can stretch your image as much as you like. The number of pixels can also be multiplied with some algorithms, so if you wish to make your file 4 times larger, 16 times larger och 64 times larger it is a simple matter. Sometimes it makes sense to do so for printing, but mostly there is no need to alter the number of pixels.

You can print any size from the files your camera makes.

Here is an example of an image that has been enlarged from 12 to 48 megapixels:
