In this tutorial we’re going to be working with the Cutout Lab in Photopaint. At some point when working with images you’ll realize that you want to isolate an image from the background. As a result, you’ll have to create what is called a mask and this allows you to use the object in a variety of compositions.
We’re going to start cutting this image out from the background in a moment, but before we do, I want to draw your attention to the Objects docker on the right. You’ll notice the background image, there’s an Object that I’ve filled with green and a copy of the background that we’re going to use as our working Object, or layer, when we’re creating the mask.
The purpose of the green layer is for when we finish the masking process and we’ve exited the Cutout Lab. What I do at this point is I zoom into the image and look at the edges of the mask, which I check against this high contrast background, to make sure that there are no artifacts, or holes in the image. Once that’s done I’ve completed the masking process.
Before I access the Cutout Lab, I need to make sure that the top Object is active, then I can start masking. One last thing to consider, when you’re masking objects, I recommend using a drawing tablet like the Wacom for precise direction and control. Unfortunately, the mouse is very clumsy to use and is like gripping a club.
To get started, go to the menu and choose Image: Cutout Lab. In the Cutout Lab dialog box, the first thing to do is to zoom into the image to see the edge in more detail. To do so, use the Zoom tool to move in closer on the cactus.
The next thing to do is to make use of the highlight tool and using it to define an edge around the cactus. The default tip is a bit too small, so I’ll dial it up a bit, to 19. So now I highlight the edge, which lays some color over the cactus and the background. And this is needed in order to create a mask. When working around the spines, there’s are a bit unwieldy with a tool tip of this size, so I’ll dial down the size of the nib. If you make a mistake in the the image, simply click on the Eraser tool and remove what you’ve done.
As you work your way around the image, use the hand tool or scroll bars, zooming in as necessary. When the edge defining is complete, I’m ready to fill the object. The first step is to zoom out so I can see the entire image, then click on the Paint bucket. Next I click on the middle of the image to fill it, in preparation for the image preview.
To preview the image, I make sure the background is set to None which will create a checked pattern in the background. When I click on preview I can start cleaning up the edge, but it’s a bit difficult to see, so I start experimenting with other options, such as black or gray matte.
Using gray matte, I can see some artifacts around the edge and that parts of the mask have holes, which need to be fixed. To fix this, I use the touch up tools to add detail or remove it. And of course, I need to check the entire image. If the image looks ragged on the edges, I click on the Add Detail tool to fil in the gaps. It’s much easier to do this now, than after the fact.
This completes the cleaning up of the image and it’s ready to be cut out. There are three options: Cutout, Cutout and Original Image or Cutout as click mask.Here, I chose Cutout and Original image, which gives me a new Object in the docker, the image which has been cut out and the original below that.
This is where my acid test comes into play. We turn off the object below the new cutout and now we see straight through to my green high contrast object. We can look at it in more detail and see if it needs further retouching. To do so, zoom in to the edge and see what’s happening. In this case the edge is still a bit ragged, which we can improve by using the eraser tool. And we slowly work our way around the image, erasing those bits as necessary.
Here, the edge is fairly sharp. If you want to soften it a bit, we would use feathering, but that’s the subject of another video.
