black – the layer with the frame on it disappears and the toddler picture shows through the parts i coloured
white – the parts i coloured in get replaced, frame picture is restored
gray – the oposity is weak depending on how light or dark ur shad of gray is
move tool – it changes what parts of the picture shows through the parts i coloured blackk
unlink/move – the areas i used the brushes on dont move but the picture does and the effect looks different when i move it becuase its the same strokes but in different areas of the frame layer
