Is this what you want? In adjustment layer options set the angle to 45 to get the square, check the reverse box. For the white square in the middle of the gradient use this workaround: 1) create new layer 2) with marque tool make the selection in the center of the gradient (hold ALT+SHIFT while draging to constrain the proportions) 3) press CTRL+backspace to fill the selection with white color, deselect. 4) Go to filter-blur-gaussian blur and set the amount to about 18%. Now you have blending from black trough grey to white ;) Tihomir
