Use the Paint Brush Tool with its colour set at a tonal value of grey, 50%, say.Create a mask then do one of the following:.Greyscale masks are great to work with images of high contrast as they give you a high-level of control over the adjustment's opacity. Greyscaleīased on dark and light values, this type of masking can be used to control the amount of visibility of the added effect, adjustment, etc. On its context toolbar, tap To Selection. You can use the Pen Tool to draw a closed shape that can be made into a mask. See Edit selection as layer using Quick Mask mode for more information.
You can create a mask from a selection which has been 'painted' on your image using Quick Mask mode. It can be moved within the Layer stack to affect greater or lesser areas. (Optional) Refine mask selection and decide on its output.īy default, a created mask layer is clipped to the selected layer or added at the top of the Layer stack if no layer is selected.The added mask will hide areas outside a selection (if a selection is in place) or display the entire layer (if no selection is in place). Make your selection then do the following on the Layers panel:.To create a mask based on pixel selection: Great when working with subject selection in portraiture or still life, where adjustment levels are targeted to a specific pixel area. Masking can be performed using a number of methods depending on the desired effect. Mask layers can have a unique blend mode assigned. Any adjustments made on a mask can be returned to and modified without any loss in image quality. Layer masks allow for a non-destructive workflow. For example, a selection of blur, sharpen, distortion or noise filters can be applied to mask layers, as well as layers with mask layer properties such as adjustment layers, live filter layers and masked fill layers spare channels can also take destructive filters too. You can apply destructive filters to mask layers. Adjustment layers inherently come with their own masks. Areas of an adjustment layer can be revealed or hidden in the same way as with a mask layer. Alternatively, mask layers can be added to layer groups so they only affect that group.Īdjustment layers and live filter layers also have mask layer properties. They can also be clipped to individual layers so that only that layer is affected. Mask layers affect any layer below them within the Layers panel. Masks are applied as a separate layer, allowing them to be freely edited and moved.
This is governed by the mask layer's positioning in the layer stack. Masking can be applied at any level on the Layers panel-as an independent mask layer or applied to a specific layer or to a layer group.
