 |

Hi,
I'm fairly new to graphic design and Photoshop. I'm having problems editing pictures. When I want to delete the background and just have the object or person in the picture, I use the magic wand tool to delete the background then clean up with the eraser. BUT the outline of the object always looks jaggedy. This doesn't happen when I use photographs with the white background.
Is there some sort of trick I'm missing? Or do I just need more practice with the eraser tool? 
Thanks!!! |

Welcome to the world of Photoshop... you have got A LOT to learn. ;-)
There are MANY ways of removing backgrounds in photoshop IE Layer Masks, Alpha Channel techniqus, and the Pen Tool just to name a few. One thing they all have in common that you are going to find out fast is how to use selections. too much infomation to get into deatal here to find out how to use each one - trust me. ;-)
One of the reasons you're graphics/ photos may look jagged is because you are not zoomed in on what ever you're working on all the way to 25, 50, 75, or 100%. to zoom into 100% a quick way is to hold down the ctrl (or command key on a mac) the atl key and the ins key on your keyboard. if your photos aren't jaggy looking when you have zoomed into them at 100% then when you go back to lets say 65% and they still look jaggy, they won't be jaggy when you print them out unless your photo rez is set to a low rez like 72 dpi. But that is a whole different beast in it's self to explain.

I would avoid the magic tool as much as possible, to harsh a tool for most extractions. Use a big eraser set at 100% for all the big stuff but avoid the final clean up area completely. Then try smaller eraser set hardness to 90% - 97% (just an idea for starters) this way when you close along the edges it will leave a smoother line.
Good luck,

I use the pen tool, make a selection, feather 1 pixel, and it makes a great edge for tubes etc..
