Abstract
Worldwide, Adobe Photoshop is the primary means in research for altering images. Training on the use of this powerful tool most often is peer to peer within a laboratory, or it is self-taught through trial and error. As a result, varying amounts of visual data can be removed unwittingly; contrast- and brightness-enhancement of images can be done without adjusting color and grayscale levels to conform to the output (which includes publication, projection, Web placement, and inclusion into Microsoft Word and Adobe Acrobat); images can be unethically altered; and pixelation can be introduced. Correct methods for use of Adobe Photoshop are outlined in this unit so that these errors can be avoided. © 2017 by John Wiley & Sons, Inc.
修改数字图像时的实际考虑
在世界范围内，Adobe Photoshop是研究改变图像的主要手段。使用这一强大工具的培训通常是在实验室进行点对点的培训，或者是通过试错自学。因此，不同数量的视觉数据可能在不知不觉中被删除;图像的对比度和亮度增强可以在不调整颜色和灰度级别的情况下完成，以符合输出(包括发布、投影、网页放置和包含在Microsoft Word和Adobe Acrobat中);图像可以被不道德地改变;并且可以引入像素化。在本单元中概述了使用Adobe Photoshop的正确方法，以便避免这些错误。©2017 by John Wiley & Sons, Inc。
