在不改变分辨率的情况下,如何使照片变小且不改变清晰度?
推荐回答(5个)
备用材料:电脑,大图片,photoshop软件(PS软件)。
1,准备好安装有ps软件的电脑,以及要处理的图片。

2,以下图为例,可以看出处理前图片要2.71M。

3,打梁做开PS软件,这里任意版本的ps软件均可以。软件打开后选择菜单“文件→打开”菜单,或者直接按快捷键“Ctrl+O”(注意游渣宽是字母,不是数字)。

4,在弹出的窗口中选择刚才准备好的图片。然后点击打开。

5,重新选择菜单栏“文件→存储为web所用格式”。如图所示:

6,会弹出一个新的窗口,这里可以设置图片的质量,显色模式等等,这个可以不管,我们点击存储按钮。

7,在弹出的窗口中选择存储位置和文件名(为了区别在后面添加了(缩小后)),然后点击保存。

8,下面我们找到处理后的图片,看看大小。看,图片大小只有795k大小了。

9,下面我们比较一下图片的清晰度。我们可以神亮看到图片的清晰度一点儿也没有降低。

不改变图片大小改分辨率慎冲。
1、新建图片:分辨率300,像素为358*441 ,加入相机拍摄的头像。
2、文件--存储为web所有格式--选JPEG--优化菜单(选择右上角“三”)--优化文件大小--18kb--确定。
3、再用dpi工具进行设置分辨率为300。
4、稍微有些模糊,是20kb的限制,但不影响。只用ps不容易整。
不改变分盯指辨率:
一寸和大尺寸图片保存时,保证分辨率方法:选择“图像--模式--RGB颜色”,再“文件--存储为凯孝配--jpg”,保存--确定即可。(png可保存透明图,在此不需要)
用光影魔术手,编辑这张照片,保存的时候有文巧誉件质量的选项,适当调低正乱,旁边显示有文件孝清段的大小变化,直到调整到适合的大小。
打开PS 重建个文件 尺寸和分辨率铅春戚按你要求来 把图片拖拽到新建的文件里 CTRL+T调整大小 另槐陵存为森州后 选择存储的图片质量即可
用PS吧。
另存为选择质量较低的就行。其实所谓的清楚只是相对清楚。
