Fluid Mask 3 – Masking & Isolation Software

Let’s revisit one of our first Photoshop tutorials on the topic of “Isolation”. One method of image isolation we failed to talk about was a possibility of using third party plugins such as “Fluid Mask 3” by Vertus. Available on Mac and PC, Fluid Mask 3 is a masking/image isolation plugin made for Photoshop CS2-CS6. Additionally, it can also operate as a standalone app.

Let’s start with the basics. We will be testing the plugin on a Windows 7 64 bit machine with Photoshop CS6, but the same functionality and workflow apply to all supported platforms as well as versions of the Adobe software. Installation of the plugin was a breeze. Run the install file, check the Photoshop version you have installed on your computer and you’re done. If you had problems installing other 3rd party plugins before, this one shouldn’t give you much trouble.

Edge Finding Settings

Once installed, you can launch the plugin by opening  any image in Photoshop, then going to “Filters” menu and selecting Vertus > Fluid Mask 3. This will open a brand new application window with your Photoshop image already loaded into it. The application will immediately start analyzing the workspace for edges. You will also notice a set of red and green brushes on the left hand tools menu. The basic idea is that you will paint in the areas you want to keep with green and mask in red. The blue outlines in between keep and delete areas are what make this product unique, they are blend areas that create smooth edges around the outline of the subject. Mastering these blend lines will help you achieve perfect isolation.

As with any isolation job using traditional Photoshop tools or 3rd party plugins, for best results you must use as higher resolution image as possible. It has to be also said that default plugin settings will not always find the right edges. Playing around with the “Edge Finding” options on the right hand side can yield much better results on 2nd or 3rd try. For example, lowering edge width threshold, slightly increasing the number of edges and setting edge contrast to high works really well for this image of a stuffed bunny toy.

Tools

Remember to hit apply to let the software analyze the image again with new settings. You can improve your selection by painting outside the software generated edges with the “Exact Keep” & “Exact Delete” brushes. Painting over troubled areas with “Blend Exact Tool” (blue pencil) will help you smooth out the outlines and fix hard to reach places, such as gaps and edges that are only a few pixels wide.

Hit “Create Cut Out” on the left hand toolbar to create the isolation. You can always switch back to rge normal workspace by hitting “Workspace” tab at the top. Clicking File > Save and Apply or the usual shortcut “Ctrl +S” on the PC will finalize the isolation and close the plugin, taking you back to Photoshop. You will not be able to go back to the same workspace in Fluid Mask 3 once this is done (unless you undo all your changes and star over), so it’s best to make sure you are satisfied with the mask while still working within the plugin window. If you happen to have overlooked a few tiny areas, Photoshop’s “History Brush” tool can help you save the day.

What We Like About This Plugin:

Workflow

Even though you can get pretty similar if not better results with the Refine Edge tool in Photoshop, Fluid Mask 3 workflow seems so much easier. Working on complicated subjects with the Select Tool can get pretty stressful at times; painting in edges is certainly easier. Additionally, the Fluid Mask workflow is adoptable to many types of images, while you may have to try different techniques for different images with traditional Photoshop tools. People working with large batches of files that need to be isolated may also reap the benefits of faster workflow with Fluid Mask plugin.

Controls

If you are familiar with Photoshop controls and shortcuts, learning Fluid Mask should be a breeze. Once you take in the core concept of edges and blending, the rest of the functionality should be relatively easy to figure out on your own.

Preview Cut Out Tool

The plugins lacks live preview feature, you have to render the image each time you want to preview your isolation. However, “Preview Cut Out” tool is the next best thing. Select it using keyboard shortcut “T” and draw a rectangle over the area you want to preview. It will be very helpful when working on areas of the image with problems.

Patches

patchIf your edge finding settings work for 99% of the image, but there is still that one area that gives you problems, Rectangle Patch tool can help save the day and a few minutes of work. Select the tool and draw a rectangle over the problem area. Checking “Analyze Separately” box will allow you to apply different edge setting to the area. You can have multiple Patches on one image.

Smart Edge Blending

Have you ever worked on an image where parts of the subject were out of focus? Feathering the outlines of the subject will ruin the areas of the image that are in focus. Smart Blending was created exactly for this purpose. It uses sharp blending on edges with a lot of contrast that are in focus and more feathering on areas out of focus.

Is Fluid Mask 3 the perfect solution for image isolation? No, this plugin isn’t a tool that can create a perfect mask with a push of a button. As with any technique you chose, you will always run into some problems, but it does a good job and depending on the image, as well as your personal workflow, it can save you hours of work. Remember to use high resolution sources and that the more time you put into an image, the better your isolation will be.

For me personally, the most important thing about Fluid Mask plugin was that it creates very natural blends, keeping a lot of detail on the subject edges. Over the years of practice I’ve gotten very used to “Select” and “Refine Selection” tools in Photoshop, but while creating very smooth cut outs I end up losing a lot of edge detail. This plugin has solved that for me. Fluid Mask 3 is currently available at 50% off over at Photowhoa.com

  1. I have been a Vertus Fluid Mask user for many years. They have the worst support site I have ever come across, and now I can’t even download the latest version (I already have version 3 but I get a nag screen telling me to update).
    Given that I cannot download the latest version, or get any support, my question is “are they still in business?”

    • Can’t comment on Vertus support as we haven’t had to deal with the company directly yet, but its unfortunate that you had to deal with this. Their company blog is still being updated, so they are still in business. Unreliable support is a common problem for many small companies like that, good luck trying to reach them.

      Don’t forget to let us know in the comments if you ever get your issue resolved.
