Increasing this parameter will give you more detail by making the weaker mask details stronger.Įdge Shift shifts the mask edge by one pixel in either direction. Mask Strength determines the brightness of the mask. The lower the parameter, the softer (more feathered) your edges will be. The higher the parameter the harder your edges will be. It’s a blending and merging tool.Įdge Hardness determines how hard your mask is applied to subject edges in your image. The desaturate slider will allow for natural transition with a new background. It takes more time to calculate especially with high quality set. The recovery slider will try to discriminate between foreground and background, Recovery set to 100 especially with hair. Once your mask is created the Adjustment options will appear, allowing you to refine your mask further. AdjustmentsĪfter you make your trimap selections you will need to click on “Compute Mask” for your selections to be analyzed and your mask created. The transparency brush is key for images where transparency is a factor because it will allow users to select a foreground color, such as the white of a wedding veil, and a background color to be removed from behind the veil. This brush allows you to define two colors (keep/ green and remove/red) to target at once. It's also great for dismissing blue sky colours from landscape views as well. This works great with selecting a shaggy white dog from a grass background, for example. The mouse turns into an eye dropper to select the relevant colour for keeping and colour. Moving to a single colour selection allows mask selection based on colours to keep or cut. Spectrum of shades affected within the image based on the main color selection. The Color Range slider allows you to determine the These brushes allow you to brush out the foreground or background area in your image, based on the color selected and the setting of the Color slider. The Color Range brush selects or deselects based on color The “keep view” with a colour background helps identify the ghost or ambiguous areas. Then a compute mask is hit to set up a draft or initial mask. The primary brushes will turn into the Topaz Magic brush after you select Compute.Ī red fill bucket is used to drop out unnecessary background generally. The primary (or basic) brush tools allow you to select the elements in the image that you want to keep (green), remove (red) and compute (blue). Brush sizes range from 1 - 255.īrushes include a magic brush to aid decisions on what should be in the mask But it's always best to outline with blue compute brush rather than second guess where the boundary of the mask occurs. The thicker the blue the longer it will take to compute. Initially you start with everything as green. The magnifying glass offers access up to 400% - effectively pixel level, if necessary. You can also pan your image by holding the spacebar and moving your mouse or even using the red selection in the preview navigator. The hand icon (or Press H) lets you drag the entire image in the work area around for ease of editing. The arrows represent undo and redo, the cropping square allows you to select a smaller part of the image to work on. There are tools to develop and focus on your image below the preview navigator The cut view shows the original image with the keep selection deleted. You can also alternate the transparent background with solid colours as well to highlight how the mask is working. The Keep view which features a checkerboard transparent background shows the resultant image from the mask. You can also rebrush a section in blue if you are unsure of its status (to keep or discard). The TriMap view sets the boundaries between what is being discarded (red), what is being kept (green) and what requires more attention and refinement the so-called "compute" area (blue). The Mask view is useful for cleaning up stray bits of image not required. These views are all live in that an edit or an action on any one of the these (apart from the original) will change the view in the others.
