The Eraser Tool -> Background Eraser Tool -> Magic Eraser Tool

Some of the other tools are rarely used like the smudge and the dodge tool but when used correctly, they result in a very beautiful effect.

The First tool is the Move Tool (V). That (V) is the shortcut key, so instead of clicking on it you can just press V on your keyboard and boom.....there it is. This tool is used to move layers around in the canvas.

The Marquee tool is just right under it. It's good to create shapes, columns and rows. I personally use it mostly in web designing but that's not the only use.

The Lasso Tool is in 3rd place and is one of the most important tool in photoshop. For example, you've got an image and it consists of 3 people sitting in the country side waving. Now you decided you want to cut one of them and put it on another image but only him no background or else. All you got to do is go around him with the lasso tool, the trick here is to be calm, really calm, then when ready you connect the lasso tool with the very first box marker.

Hint: You can zoom in the image to be more accurate. Once you have started the lasso you can't stop and continue later you need to finish it !

Right at the 4th place there is the Qucik selection tool or Magic Wand. They have roughly the same job, instead of using the lasso if an image is very clear with high definition it can go around it alone, just by clicking on the item.

At 5th place, The Crop tool. It is used frequently, mostly at resizing parts of an image. You need to create a square around the text or image you want to copy to another canvas so that you can work easily there and then right click and crop.

At the last of this section of tools there is the Slice Tool used in web designing to slice the web template.

Hint: Do not use this instead of the crop, they don't have anything to do with each other's uses.

That's all for this tutorial, I will explain some of the rest tools in my next tutorial. See ya and just try to experiment with your photoshop, the more you use it, the more comfortable you get with it.

Thanks
