Understanding pixels, megapixels and video resolutions

Megapixels can be quite confusing. They are generally used in cameras to tell you how good the picture will be. One megapixel is one million pixels. A pixels is a tiny dot. If you look at a screen very closely you can just about see the pixels.

An example of where you might find megapixels is on a digital camera box. At the moment, a good amount of pixels for a digital camera is probably around 10 megapixels.

In films and TV, standard definition is 720×480 pixels which can be multiplied to give 345600 pixels. This means the total resolution of one frame of video at standard definition is 0.3456 megapixels. In high definition video, there are two different types - full HD/1080p HD and 720p HD/half HD. 720p HD is 1280×720 pixels which gives 921,600 pixels when multiplied. That is nearly one megapixel. Full HD is 1920×1080 which gives 2,073,600 pixels which is about 2 megapixels for each frame. This shows how much better picture quality you can expect from HD compared to SD but HD also takes up far more storage space.

Hama Star 75 Tripod

This tripod from amazon is, In my opinion, quite good. It weighs 620g and comes in a carry bag. Its height when fully extended is 125cm and its height when collapsed is 42.5cm according to the manufacturer. It uses clips to secure the legs when extended, unlike the old one I had before this. It also has a useful spirit level for the tilt.

My favorite watermarker- Exif watermarker

My favorite watermarker- Exif watermarker is my chosen number one watermarker because it is simple and easy to use and offers resizing as well as watermarking. The program is free but you can buy a license key to remove the reminder- yes reminder, not plural. It only shows one single reminder when the program starts up. It works quickly and produces high quality files (Provided you set the quality quite high). I actually use it for the pictures in this blog, so take a look at them.
