Adobe Photoshop Lightroom 5正式版终于发布了,并且现在登录Adobe官方网站可以下载到Adobe Photoshop Lightroom 5正式版的试用版。不过小编发现使用Adobe提供的下载按钮一直都没反应,最终在网页的源代码找到了下载链接。
Adobe Photoshop Lightroom 5新增了非常多的功能,比如Smart Previews,即智能预览功能;进阶笔刷,则大大提升了笔刷的精准度,即使是不规则的或者无条理的线条纹理,现在使用Adobe Photoshop Lightroom 5处理起来也变得小菜一碟;还有Radial Filter,调整效果局部强弱的放射渐层的滤镜功能;再有Visualize Spots tool,辨识杂点工具,处理起扫描件的杂点脏点变得轻松简单;?Upright功能更是可以帮助你修正因为仰角拍摄景物随之而来的型变而节省高昂的移轴镜费用……
小编并非专业的摄影师或者图像处理专家,但Adobe Photoshop Lightroom一直以来的口碑值得我们信赖它的这次升级会带给我们更多的惊喜。不过最新版的Adobe Photoshop Lightroom 5价格也不低,售价高达149美元。对于国内收入水平并不高的人来说,可能更多会选择等待破解版Adobe Photoshop Lightroom 5的到来。
最后附上Adobe Photoshop Lightroom 5正式版的下载地址,建议使用迅雷进行离线下载,同时如果发现无法下载时,请登录Adobe英文网站试试,需要注册Adobe账户。

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.
