How do you make a transparency on the PC

I am taking an object & putting it over a blue screen to have contrast but its quite strange that when i picture it, using photoshop magic wand & i can't get it to take away all the blue layer at 1 shot, also, there seem to be 1 blue pixel line around the object. how do i go about fixing it?

If you're talking about taking off a blue background away from an image, you can set the tolerance level of the magic wand, check contiguous and anti alias.

Once the background is selected, go to your channels, create new alpha, and give the selection a stroke of 4.

Deselect, blur the outline, invert (ctrl + I).

Go back to your layers, select filter -> extract

Under channels, choose Alpha 1

Fill the selection that you want to extract and click ok.

THe blue background should be gone by now.


If thats not what you want, then i dun understand your question.

it works.
just some definition have to look up.

but my object have black stopper which happen to be the same color as the shadow & can't use flash as the object is metal so it will reflect the light.

so instead, i delete the background & copy the shadow as well.
