Select Subject (AI)

Select Subject uses AI to find the people or the main object in your photo and select them in one click — no careful lasso work. It can also hide the background with a mask straight away. The AI runs on your own computer; your photo is never uploaded. Supporter

Where to find it

• Select › Subject
• The Select Subject button in the options bar of the Magic Wand and the Quick Selection Tool (W)
• ✦ Select Subject in the Properties panel, in the subject mask refinement section, together with its settings
• The Remove background tile on the Home screen: pick a photo and SnazzyFoto opens it and runs Select Subject for you

In the free version

Select Subject is a Supporter feature. In the free version, a Supporter feature window appears instead:

1. 1 Donate & activate — donate any amount from the minimum and unlock SnazzyFoto on this computer.
2. 2 I already donated – sign in — for when you have donated already.
3. 3 Not now — closes the window.

See Supporter for how donating works. Everything else on this page, including Select Sky (without the AI), works in the free version too.

Select the subject

1. Open a photo.
2. In the Layers panel, click the layer that should get the mask — usually the photo itself. The AI looks at the whole visible picture.
3. If you like, set the options in Properties first (see below). The defaults work well for most photos.
4. Choose Select › Subject. Analyzing subject… appears while the AI works; this takes a few seconds.
5. The subject is selected. With Create Mask ticked (the default), the layer also gets a mask: the subject stays visible and the background is hidden.

Options

1. 1 ✦ Select Subject — runs it with these settings.
2. 2 Model — Any subject (the default) finds people, animals or objects. People (fine hair) is made for people and keeps loose strands of hair better; try the other one when the first gets a photo wrong.
3. 3 Create Mask — when ticked, the active layer also gets a layer mask. Untick it if you only want the selection.
4. 4 Holes — what to do with gaps inside the subject, such as between an arm and the body. Auto fills small gaps and keeps larger ones, Preserve keeps every gap see-through, and Solid fills every enclosed gap.
5. 5 Fill — how strongly small gaps and rough bits along the outline are closed (0–100%). It has no effect with Preserve.
6. 6 Feather — softens the edge, in pixels (0–24). Raise it for hair or a soft background blend.

What to do next

• Put a new background behind the person — add Layer › New Fill Layer › Solid Color… or another photo with File › Place Embedded…, then drag that layer below the photo in the Layers panel.
• Fix the edges — paint on the mask: the Brush hides more, the Eraser brings parts back (see Paint on a mask).
• Work on the background instead — choose Select › Inverse (Shift + Ctrl + I), then blur it, darken it or change its colour.
• Copy the person onto a layer of their own — untick Create Mask, run Select Subject, then press Ctrl + J.
• A softer edge — raise Feather and run Select Subject again.

Select Sky

Select Sky selects the sky in a landscape or outdoor photo. For a Supporter the AI finds the sky, also behind trees and buildings. In the free version it uses a simpler method without AI: it looks for bright, even areas that touch the top edge of the picture.

1. Choose Select › Sky, or click Select Sky in the options bar of the Magic Wand or the Quick Selection Tool (W).
2. The sky is selected. If SnazzyFoto can't find one, the status bar says No sky found.
3. Use the selection, for example: add a Hue/Saturation adjustment layer to make a blue sky deeper (it gets a mask in the shape of the sky).

Without the AI it works best on a clear or evenly clouded sky. Trees, buildings and busy clouds can be missed or added — fix that with the Magic Wand or Lasso while holding Shift (add) or Alt (subtract). To replace the sky completely, use Sky Replacement in Develop Supporter.
