把照片放进Iphone手机里为什么会模糊（蓝铭原创）
模糊的原因其实跟一个参数有关：分辨率DPI（这个分辨率不是宽度和高度的分辨率）![](https://wkrtcs.bdimg.com/rtcs/image?w=293.60&md5sum=fa0a286e04142a348a753a4979a01920&sign=bcffa6a349&rtcs_flag=2&rtcs_ver=3.1&l=webapp&bucketNum=24&ipr={"t":"img","w":"293.60","h":"378.00","dataType":"png","c":"word/media/image1.png","imgOriW":367,"imgOriH":473})

如果放照片进iphone手机模糊的话，请检查照片属性里的水平分辨率和垂直分辨率。因为很多相机照出来的照片的分辨率都很高，但适合iphone手机的分辨率为72 DPI就够了，太高的话肯定模糊。
如果分辨率高于72的话，要调过来也很简单。需要软件Photoshop。
1. 用Photoshop打开照片，选择图像-图像大小。2
2. 去掉重定图像像素的勾。
3. 然后把分辨率改为72就行了。
4. ![](https://wkrtcs.bdimg.com/rtcs/image?w=329.60&md5sum=fa0a286e04142a348a753a4979a01920&sign=bcffa6a349&rtcs_flag=2&rtcs_ver=3.1&l=webapp&bucketNum=24&ipr={"t":"img","w":"329.60","h":"272.00","dataType":"png","c":"word/media/image3.png","imgOriW":412,"imgOriH":340})
保存。
