how to adjust selection with magnetic lazo tool?

[mohamedh78426672]

lets say that after using the magnetic lazo tool i want to improve the selection moving the dots in or out without having to do it all over again, what's the easiest way to do this?

Also, if i leave the hairs for later, what tool can allow me to select hairs without selecting the entire figure again? thank you

use Layer Masks and then Select and Mask for the hair. Also, do yourself a favor and use Select Subject, not the Mag Lasso.

If you are using the Magnetic lasso, there are two tricks:

• Backspace to remove segments
• Click instead of drag to place point where you want them

But don't use it if you have a recent version of Photoshop, as Select Subject and the Object Selection tool are so much better. 

• Object Selection is in the Tools panel

• Select Subject is in the Select menu and/or the options bar when you have a selection tool.

What version of Photoshop do you have?

Select Subject and the Object Selection tool both came out several versions after CS6. I think you have Refine Edge for the hair, but it doesn't work as well as techniques that came out after CS6.

thank you!

just another question, i tried selecting hair with  with channels and it worked, i used the red channel because it had the most contrast between hair and background to create a mask and it was simple just like select subject

the problem is it selected everything that was black, so all i had to do is paint white on the mask to deselct the shirt, it worked but i still see pixels coming out of the shirt, what did i do wrong?

also to avoid this in the future, how can i use channels to select just hair and not the entire figure? thank you i will watch tutorial about refine edge

Because you're using CS6 which doesn't have all the newest Photoshop selection options, you might instead try using Adobe Express which has a quick action to Remove Background (https://express.adobe.com/sp/tools/remove-background). Then you can bring that resulting image back into Photoshop for additional editing.

OMG! Can't believe it's that quick!
