روشهای انتخاب قسمتی دلخواه از عکس

تاریخ:جمعه 6 بهمن 1391-07:12 ب.ظ

شما برای اینکه افکت ها و ویرایش های خاصی را روی قسمتی از عکس انجام دهید، اولین کاری باید کنید این است که آن قسمت از عکس را انتخاب کنید.

برای  این کار دو روش کلی وجود دارد:

1.استفاده از ابزار براش؛ که به اینصورت است:

ایتدا رنگی را انتخاب کنید( بهتر است از رنگهای سفید، سیاه، قرمز، سبز و زرد استفاده کنید.)
سپس آنرا به اندازه مناسب در بیاورید.
حال یک لایه جدید باز کنید و سپس قسمتی را که میخواهید انتخاب کنید رنگی کنید.



حالا با استفاده از ابزار magic wand قسمت رنگ شده را انتخاب کنید.


و سپس دکمه ی Delete یا Del  روی صفحه کلید خود را فشار دهید.

حالا شما باید فقط قسمت انتخاب شده را داشته باشید.
تغییرات مورد نظر خودرا بر روی لایه اول (background) انجام دهید و پس از اتمام کار، لایه دوم( layer 2) را حذف کنید.


2. استفاده از ابزار قلاب (lasso)

برای این کار شما باید ابتدا ابزار lasso  را انتخاب کنید.
سپس به صورت دستی با ماوس مناطق دلخواه را انتخاب کنید.


این روش مقداری سخت هست و دقت بسیار زیادی لازم دارد. اما بسیار دقیق است.


در کل در مقیاس های بزرگ روش اول بهتر است اما دقت و کامل بودن روش دوم را ندارد.

I've been browsing on-line more than 3 hours nowadays, but I by no means discovered any interesting article like yours.

It is beautiful worth enough for me. In my view, if all site owners and bloggers made just right
content material as you did, the web will be much more helpful
than ever before.
