How to change start and endpoint of existing gradient mask?

mylifeuncut
Hi everybody,

I am very new to C1 -- so please bear with me as the answer to my question might be very obvious. I couldn't find the answer by searching this forum and other online resources, though.

A gradient mask is easily created by clicking a starting point (where the mask is dense) and dragging to an endpoint (where the mask fades). But what if I change my mind and want to drag those two points slightly farther away from each other or closer together or just move one of those two points? Is this possible (like it is in Lightroom) or do I really have to draw the mask over and over again until I get it just right?

Thanks for any help...

M.

    I am new as well. Here is what I observe.

    Using the Gradient Mask is awkward but not inelegant once you get used to it. Fine-tuning it visually is possible.

    Note that Gradient Masks always cover the area from one or two of the Images edges to the masked/not-masked boundary.

    Your initial click does not set anything. The segment created by clicking, dragging, and releasing determines the Image edges on which the Gradient Mask starts, and the placement and softness of the boundary between masked/not-masked.

    Where you release the mouse cursor fixes the end of the Gradient Mask.
    The length of the drag determines the softness of the boundary between masked and not-masked.
    The angle of the segment between where you click and where you release sets the angle of the boundary between masked and not-masked.

    Note that the masked/not-masked boundary can be adjusted within a wide range of hard to soft.

    Once you have drawn a Gradient Mask, make is show (press the Cursor Tool Icon in the Toolbar and select "Always Display Mask"), and set Selection Points to show as well (press the Cursor Tool Icon in the Toolbar and select "Show Selection Points"). At this point, even though the mask was created using the Gradient Mask Cursor Tool, Capture one understands it as simply a mask. There are three Cursor Tools modes: Draw, Erase, and Gradient. When Draw or Erase mode is active, a single selection point shows for the mask created in Gradient mode. So to move that mask, change to Draw or Erase mode, and click-and-drag the Mask Selection Point.

    Moving the mask is not of much use, IME.

    In Draw or Erase modes, the cursor functions as a brush. You can add to it, or subtract from it. (Make sure the layer with the mask you want to edit is selected in the Local Adjustments panel of the Local Adjustments tab of the Tools Sidebar.)

    In Gradient mode, the behavior is mixed, but easy to control once you know a bit more about how it works. There are two behaviors: adding to the existing mask, and replacing the existing mask. Which behavior you effect is controlled by the direction you drag: if you click and drag in the same direction as was used to create the mask (put another way, in any direction that matches "from the mask to the non-masked area"), you add to the mask. If you click and drag opposite to the direction used to create the mask (in any direction that matches "from the non-masked area to the mask"), you replace the existing mask with a new one.

    In sum, to make a Gradient mask:
    - click and drag in the direction you want your mask, from Image edge to mask boundary
    - click and drag in the same direction to move the boundary
    - the angle of the segment between clicking and releasing the mouse cursor determines the angle of the boundary
    - long drags make the boundary soft
    - short drags make the boundary hard
    - you can additionally brush on and erase the Gradient Mask with the Draw and Erase Cursor Tools.

    Afaict, this implementation works well for creating gradient masks that extend to the edges of an Image.

    Thanks for your long reply. Especially the information about adding to or replacing an existing gradient mask was really helpful.

    But to come back to my original question: It seems that it really isn't possibly to adjust an existing gradient mask as it is in Lightromm, is it? Am I the only one who is bugged by this? C1's implementation just seems so much more cumbersome and less intuitive than Lightroom's... (Sorry... 😕 )

    I don't use Lightroom and don't know how gradient mask adjustments are done by its users. Hopefully someone who does will chime in.

    The gradient tool is not editable like in LR: you cannot mone the start or the end line, nor the direction afterwards. It's just a tool to draw pixels in the mask. It's like in PhotoShop. Once drawn, it's just a bunch of pixels. You can change it with the brush/eraser tools, or draw a new one.

    I wasn't aware of the 'add to' feature, AFAIK, you always draw a new mask. Need to check that out.

    Cheers,
    Peter.
