Just because a camera or webcam says it is 15MP (mega pixels), does not mean that is the ‘true’ resolution of the camera.  Take the Logitech C920 webcam that says on the marketing material that it can take 15MP* (software enhanced) photos.  That is as close to lying as you can get.  The true resolution of that webcam is  2MP and all they are doing is making the file size larger to give you 15MP.  What a load of …

Anyway, before you buy, be sure you read the article below (or something similar) and make sure you know the ‘true’ resolution before buying the camera:
