If the output image is in CMYK images for printing we recommend a Gamma value of 1.8; if the image is in RGB color mode of the device output, such as other displays and film recorder or an RGB printer, the gamma value is generally set to 2.2; If the image is used to a different application or platform for output, the Gamma value of 1.8 has a much wider applicability.

如果负入图像是用于印刷的CMYK图像倡导拔取Gamma值为1.8;如果图像不兵在RGB色彩模式的撤备上负不入(如其他的表现器,胶片记录仪或RGB打印机),Gamma值凡是撤定为2.2 ;如果图像用到其他的答用步调或平台举行负入,1.8的Gamma值则具有更普及的适用性。

The finding indicates that subjects create different appearances to feature boys and girls. Clothes are the most popular approach used, followed by hair-style, action and ornaments."Girls wear skirts" is a stereotype used most often by female subjects. Most subjects describe girls' action more positively than boys'.More male subjects used negative descriptors than female subjects. Most of the subjects are aware of and concern with the social sanction of behaviors. Socially disapproved behaviors by girls are more likely to be criticized by all subjects. The concept of "girls do house work" decreases with subjects' grade level.

研究结果发现,在图像的部份,学生主要依序以「衣服」、「发型」、「动作/或活动」、和「配件」来区分男与女的差异,其中以「动作/或活动」来作区别的随著年级的增长而递增,「女孩穿著裙子」的概念固著於学生的图像表现,女学生尤然;在文字部份所表现的,「男孩图像」所得的负面描述多於「女孩图像」,男学生使用的负面描述用语多於女学生;无论男或女学生普遍都倾向於以社会价值标准来衡量不可以作的事情,其中较多的男学生更倾向於社会价值标准来界定女孩不可以作的事情。
