Once you have a selection, you may need to tweak it to refine the edges. This may mean feathering the edges so your mask is not too sharp or making the selection more precise. In this movie, author Richard Harrington guides you through different techniques for refining your image selection in Pixelmator.
- You have a couple different ways to refine a selection, you can set an initial refinement before you start, or make a change afterwards. Let me show you. Let's open up this one here called, refining a selection, and take that fullscreen. For this one, I'd like to show you a couple of options. If I grab the polygonal lasso and, I click here, on the menu, we can work with smooth edges. This'll ensure that we have a gentler transition.
Once I make my initial selection here, it may also be helpful to visualize that. So, if I choose to edit and quick mask mode, I get a pretty good idea of what's selected. After this, you can always choose to refine things a bit. In quick mask mode here, I can grab a paintbrush tool, zoom in a little bit with command plus, and simply paint, using black, I can add to that mask.
This allows me to fill in any problem areas. Holding down the shift key, as you click with the paintbrush, is a great way to paint a straight line. And you can use that to refine that edge there, so it's more accurate. That works quite well. Working in quick mask mode here, is a great way to be precise.
Let's hold down the shift key, and draw that line. That looks pretty good. Space bar. Got the pull there. That looks good. Let's go back to the lasso tool. (mouse clicks) You'll see that it becomes an active selection. Additionally, with your active selection, you can click and choose to refine that selection.
This'll put you back in the quick mask mode temporarily, but gives you the easy controls to feather that edge, for a softer transition, as well as smooth out any bumps in your selection, if there's jagged edges. Such as hard, polygonal angles. The size command will expand or contract, as needed. And then click okay to update. That looks pretty good. And what I wanna do here, is modify this, putting more saturation in the front. Image, color adjustments.
Let's run the hue there. And just intensify the color a bit. And darken it down. Looks good. Remember, as well, it's quite useful with the ability to simply invert a selection. Select, invert. This allows you to quickly change things. Now I've selected everything outside of the building front. That works out well, and I'll grab one of my tools here, in this case the paint selection tool, and I want to subtract.
Holding down the option key, I can remove parts of the sky. And now, just the other parts of the building are selected, giving me the ability to modify those. Applying another hue adjustment. Just to desaturate those a little bit, so they don't stand out as much, as that yellow building does. And darken them down a little and click okay.
Now, you might notice there, that I made an unwanted adjustment, so let's undo for a second and go back into quick mask mode. This makes it easy to see that I have some problems. B for brush, and just paint, to refine that edge. There we go. That looks good. Exit quick mask mode. Go back to the lasso tool. Have my selection. And now I can better adjust, and not get any stray changes, that I didn't want. That looks a lot better.
Now we have a mostly monochromatic background, with a strong yellow center, and the bright blue vivid sky. By working with different commands to reverse, select, modify and enhance a selection, I was able to precisely select, just the pixels that I wanted to manipulate.
