quick selection
左下角多選了一天背景琼蚯，hold option key 來(lái)deselect。
點(diǎn)擊refine Edge on top, output出來(lái)你選擇的東西惠况，可以選擇output layer or mask.
然后點(diǎn)擊保存遭庶，或者繼續(xù)操作。 可以加一些background layer之類(lèi)的稠屠。
如果用lasso tool也一樣峦睡，只不過(guò)是自己完全手動(dòng)selection。 選擇完以后top bar也會(huì)出現(xiàn)一個(gè)select and mask的output出口权埠，你可以在那里對(duì)你選中的東西搞一點(diǎn)事情赐俗。比如說(shuō)給選中的人物上色，或者output成layer弊知。
"To remove an area from a selection, hold down yourAlt(Win) /Option(Mac) key, which temporarily switches the Quick Selection Tool toSubtract from selectionmode (you could also select the "Subtract from selection" option in the Options Bar but you'd need to remember to switch it back to the "Add to selection" mode when you're done). The small plus sign in the center of the cursor will be replaced with a minus sign (-). Then, with Alt / Option still held down, click and drag inside the area you need to remove. I'll need to make my cursor smaller here by pressing the left bracket key a few times:"
補(bǔ)充一下阻逮，option key 必須得你先松開(kāi)鼠標(biāo)后再點(diǎn)。比如你一開(kāi)始點(diǎn)著鼠標(biāo)在select秩彤，發(fā)現(xiàn)多選了叔扼，這個(gè)時(shí)候要松開(kāi)鼠標(biāo)，然后再按下option漫雷，這個(gè)時(shí)候你的所有action都是在remove selection瓜富。?
