For once I will not have a stupid, dramatic, pity party post- yay! I would just like to know if anyone knows how to take images of their computer screen. I see a lot of people taking pics of their desktops and a friend of mine said I just need to press a few keys to take a picture my desktop. However, does it only take a picture of your desktop? I would like to know how to do this so I can takepictures of scenes from DVds- I swear, I only do it to get poses and facial expressions for my drawings. If anyone knows how to do this or knows someone else who does please let me know. I hate taking pictures of my screen using a digital camera because it's always glarey or there are these annoying lines in the picture or the lighting is bad.
