: Layer blending settings that turns greyscale value into transparency (subtracting lower layers) I have a photoshop file with many layers. I would like to put one layer on top where I can draw

What you'll need to do is place all of your layers into a single layer group.

From there you can add a layer mask to the actual layer group or you can place a clipping mask on the layer group.

To add the layer mask simply click the Add Layer Mask button at the bottom of the Layer panel.

The clipping mask is a layer that is placed above the layer group and is converted to a clipping mask by right-clicking it and selecting Create Clipping Mask
