Problem subtracting a selection area

[Jaime Desytec]

Hello,

I have a selection as seen in the following picture. I need to select only white area, so I press Alt button nd click to remove gray area, but a message appears telling that edge will not be visible. How can I do it?

How can I accomplish this? I have Photoshop CS6 under Windows 10.

Thanks

Jaime

Hi

What's your Feather set to in the options bar

Hello, feather value is 0 px. However, thanks anyway but I have found a trick. I did not use magic wand finally, but Quick Selection Tool. That way I could select exactly the area I wanted to select. With that tool I could add and subtract areas easily.

Regards
