 |
|
Hello, I'm completely new to photoshop and I want to learn how to use it. However most tutorials on YouTube are about boob enlargements and other trivial tasks. 
On the other hand, all the general beginners' guides available on the net are way too general and when I try to start following them I get the feeling that I'm not getting anywhere.
The specific task I need photoshop for is: taking small low-quality images and making them big and sharp 
For instance, I'd like to be able to cut out the squirrel from this image and then enlarge it to a desktop wallpaper size.

There's a youtube video where a guy does just that, but it's too fast to follow

can anyone point me to a *good* HOWTO on this topic? Or perhaps explain the most important techniques/tools that I will need in order to accomplish this task.
I know this task is really complex and totally not for beginners, but it's the only one that will keep me interested enough to keep clicking in photoshop for hours. |

What they are doing in the video is cropping out everything except the character in Photoshop, and then importing the picture into Illustrator so it can be vectorized. Then they bring the pic back into Photoshop for the color.
In photoshop, zooming more than 100% of any pic will start pixelation mainly because it's a raster program. In Illustrator, you can create vector objects, which means pixelation will not occur when zoomed in.
If you have Adobe Illustrator, then you can try searching for some tutorials on how to do this. If you need any further help, in finding tutorials and whatnot, just ask. |

Wow, thanks for the quick reply and the explanation!
Now suppose I wanted to vectorize the squirrel from this picture

do I have to manually trace every single edge, or is there a sweet semi-automated method/tool that allows me to do it? |
