Question

quick selection tool create blend between two or more column true or false ​

Answer 1

In a previous Photoshop tutorial, we learned how the Magic Wand Tool works and why it can be a great choice for selecting areas of similar tone and color. In that tutorial, we used the Magic Wand to easily select the clear blue sky in an image, which we then replaced with one that was a bit more interesting. But if any of Photoshop's selection tools deserve to be called "magic", it's not the Magic Wand. It's the tool we'll be looking at in this tutorial - the Quick Selection Tool.
