I hope this answers all of your questions. This is a real time-saver and it allows you the freedom to make changes easily. It creates a vector-like shape that can be manipulated in real time without loss of clarity. So to answer your question Alexandro, the mask is created so you can manipulate the image before you rasterize it. It also preserves the edges of the image much better than it would otherwise. This is a nice feature that keeps one from having to do a select-fill. In the above image I have selected a new color which Photoshop again updates in real time. You can see the path around the image easily here. I am really altering the mask, but it appears as though I am altering the shape itself. Photoshop updates the shape according to my changes in real time. So in the above image I have simply messed around with the paths on the shape. So this really isn’t a vector shape at all- it only appears to be in the way that Photoshop let’s you manipulate it. A true vector program would allow you to zoom in as close as you could and you would still see a perfectly smooth line. Now that we are zoomed in, you can see that Photoshop is smoothing the image boundaries just as would happen with any other rasterized image. This is much nicer that selecting and filling a shape as you would traditionally with a raster shape, since it leaves no halo or jaggy leftovers after a few fill changes. When you select a color the entire shape is instantly converted to that color. When you double click on the layer color swatch, a color picker appears. The color portion can be changed in real time just like a vector program does. Pixel layers are much more flexible than vector layers. On the layer with the rabbit you see two things – a color portion and a vector mask portion. As Photoshop is raster-based, almost all its tools prefer to be editing a raster or pixel layer. As you can see, it looks like any other rabbit you’ve seen. ![]() This is a rabbit that ships in the Photoshop shapes palette. The mask can be edited just like a vector shape is in Illustrator or Freehand, which makes it appear as though the shape is a vector. In fact they are a solid fill of color with a mask or clipping path over the top of the color to make it appear as a vector shape. I told him that I would explain the reason why the best I could.įirst let’s start out with what Photoshop vector shapes are. Last week, Alexandro Colorado emailed me asking why Photoshop creates a mask when making shapes with the shape tool.
