If you’re anything like myself, multiple failures to create a ‘clean’ mask from more advanced images were conducted in Topaz ReMask upon first use of the tool. However, with a little bit of practice along with helpful YouTube tutorials, I became more confident with the program.

Here is a useful method I would like to share with you for objects that are a similar color to the background, in this case product photography. The technique behind it is the editing that takes place after the mask is computed.

I first did a quick outline of the image in ReMask, not worrying too much about the blue outline’s preciseness, although it helps to keep the blue line as thin as possible.

3Here are some tips for making the most precise mask after it is computed:

1. After computing the mask, change the view to the 4-way display. This option can be found in the top right corner directly adjacent to the Topaz Labs logo.

Before 42. Use the basic brush (in both green and red) to brush out areas of blue, minimizing the blue outline in the tri-map. Zoom in and out using your +,- keys and try to create the thinnest blue line between red and green for the most accurate results, alternating which view you use to brush out the blue line. It is also helpful to refer back to the ‘Keep’ view when brushing in with green and red to see exactly where the object meets the foreground.

Here are a few definitions of what each does from the user guide:

transparent background5. Create a new layer underneath the masked image and fill it with black.

Final Mask6. Use the eraser tool with a reduced flow (around 40%) to smooth over edges. You might also opt to burn or dodge the edges depending on the background used to help the image blend in.
