Can anyone give some advice on how to get a "better" selection using the lasso tool.

I'm not very happy with my results thus far and am looking for a way to get a "more exact" selection.

Thanks in advance.

If you are referring to the freehand lasso{photoshop}my advice would be to invest in a graphics tablet,checkout products like the Wacom Graphire.The freehand lasso is not the ideal tool for making exact selections,try using the polygonal lasso instead.This tool allows you to draw around the object in small mouse clicks. I wish i could help you more but the subject requires more explanation than time will allow. If you google Adobe Photoshop tutorials you will surely come up with plenty of excellent instruction which should help you to become more proficient.

Your welcome, I forgot to mention in reply above that if you are selecting round, oval or rectangular shapes you should use the marquee tools that can be found in the tool bar.Once you have made your selections you can then modify them.To do this go to the select menu for further options. You are probably realizing by now that there is a steep learning curve with this digital stuff,just keep at it it's worth it.

There are several ways to get selections in Photoshop. You can use the extract filter to "draw" around the object you want to remove and then fill it in with the bucket tool and extract it onto an new canvas. From there you can erase any little bits from around the edges that are not desirable. This is especially helpful when you have an object that has an irregular edge.

Another way is to use the magic wand tool, use the shift key to add to the selection and adjust the tolerance as needed to get the selection you want. It works by selecting pixels of the same or near coloring so adjusting the tolerance will either limit or increase the size of the selection. You have to be careful using this method, for example: if your selection has white in it and other parts of the picture are white, you will choose them as well.

Hope this helps.

if you use Photoshop:

Most times i use the magic wand tool like petite does. it doesn't matter if there are some parts selected outside for now or something is missing inside. The importent thing is, that the borders of your object should be nearly perfect. Now the clue :

switch to the quick mask mode by pressing -q-
Now you are able to "paint" your selection with every tool you will find in photoshop.

use the the brush tool to "paint" missing selection parts inside of your object or erase parts outside.

by switching the color between black an white, you are able to erase or paint the selection.

after finishing just press -q- again and voila: Your selection is perfect :-)

One more info: The selection is inverted. that means:Everything, which is been painted, is not part of your selection. Sometimes it is easer to invert your selection by using the inverse funktion in the select area before switching to the -q- quick mask mode. now you can realy paint your selection and erase parts you dont like. after switching to "normal" mode (pressing -q-) re-invert your selection again.

what is it fore? There are a lot of ways how avoid any selections. You can not be precise with lasso or magnetic lasso. What you can do - is to select it excessivly, copy, open in a new window and erase what you need from outside, then it is very easy to select it and use in any purposes.
