Why we will’t use Magic Wand Instrument (W)? Since Magic Wand Instrument (W) works primarily based on shade samples so it would solely make the choice of shade space which it samples from the background. For those who click on, with this device, on the blue components then solely the blue shade pixels will likely be chosen not the remainder. You’ll be able to see the beneath picture that I’ve clicked on the blue half (prime left nook) because of this solely these components, having blue shade pixels, is chosen.


That’s why we aren’t utilizing it. Equally, remainder of the instruments equivalent to Polygon Lasso Instrument, Rectangle Instrument, Elliptical Marquee Instrument has limitation. Strive them and see why they aren’t appropriate to make use of after we’ve giant stable background space for choice.
