NotMyFault Posted December 2, 2020 Posted December 2, 2020 Hi there, i tried to use a live stack to merge several images in a HDR style. Images are exposure bracketed. I do not understand how alpha channels work in combination with live stacking: If i apply a mask to one of the pictures, the mask is effective to filter out unwanted parts. But if i try to adjust the alpha channel of the mask, e.g. with help of a levels adjustment, this does not show any effect. Is this inteded behavior, or a bug?
