My quick mask mode was working until a few weeks ago. I click on quick mask to cut out a section of a photo, then I use the brush tool. I cut out the section, I de-select the mask tool and then i make a new layer copy of that section. but everytime I do this, it seems to look transparent; like its not cutting the whole thing. my opacity is set to 100%, flow is to 100%, hardness set to 100%, but it will not cut out its whole opacity. I don't know what to do!!
