这东西实在不熟悉，请指教最能表现胶卷真实效果、能体现最高清晰度的参数设置。

" 转贴新浪网网友ejz :佳能CanoScan FS2710底片扫描仪使用报告 "

kao! ejz怎么说也是这里的版主…… 而且cheji倒是新浪的网友……而且还是版主呢

这色彩准确吗？所有的人脸都像关公似的！那张对比图左边的层次明显差于右边的,感觉好点的平板扫彩扩的照片也比他强吧？动态有3.2D?!值得怀疑！右边的动态似乎好些，可色彩怪怪的！我上次试用ACER2720似乎也是这效果，吓得我转身撤了，请看看光辉用Nikon IVED扫的片，和这完全两码事哦！

多谢Ansel，那是一个很老的贴子了，现在体会更深了，看法也有些不同了。

To cheji:
如果想扫描反转片的话，没必要使用自动色彩平衡，用2720dpi扫描，其他全部使用标准设置即可。

如果扫负片的话，没有自动色彩平衡时会有些偏品，对人像来说，肤色会比较深，但还能接受，对色彩要求很高的场合可能就无法接受了。但是，使用自动色彩平衡后，会受画面中大面积色块的干扰，出现偏色，如下面的图所示。

我的感觉，佳能的自动色彩平衡算法可能有问题，至少没有尼康的好

CanoScan FS2710 Film Scanner
Superior quality film scanning
Whether it's 35mm or Advanced Photo System format, film scanning just doesn't get much better than with the CanoScan FS271O! Its 36-bit scanning capability supports recognition of a staggering 68.7 billion colors, thus the resulting digital versions of your photos preserve the details from the very dark and very bright areas of your original with an exceptional degree of accuracy. The CanoScan FS2710 also features optical resolution of up to 2,720dpi as well as an improved color tone algorithm for more faithful color reproductions of film negatives.

Speedy scans with any film format
Not only does the CanoScan FS2710 produce great-looking film scans, but it does so with excellent speed! Maximum resolution input of both 35mm positives and negatives takes only 13 seconds, and a frame of Advanced Photo System film can be scanned in as fast as 10 seconds! CanoScan FS2710 has the advantage of being pleasantly quiet during operation, and a semi-transparent dust cover has been added to keep out unwanted particles when the scanner is not in use .

Simplified installation and more
The entire CanoScan FS2710 software package comes bundled on a CD-ROM that features a handy setup utility for loading all the items onto your computer's hard disk with minimal fuss. An Adaptec PCI SCSI board is also included to provide Windows users with the extra benefits of a Plug & Play interface and increased data transfer rate.

CanoCraft FS for Windows
Creating quality images for immediate use is easy thanks to CanoCraft FS. If the software you're currently running is TWAIN-compliant, CanoCraft FS lets you access the scanner from right within that application, and perform basic image-editing such as setting color balance, tone curve, highlights, shadows, and contrast. CanoCraft runs on Windows 95, Windows 98, and Windows NT 4.0 platforms, and supports the highly efficient .fpx image file format. A complementary program, CanoCraft Copy, offers one-step color printing of your scanned images.

Plug-in module FS for Macintosh
The Canon plug-in module FS brings Macintosh users quick and easy control over basic scanning parameters and color adjustments. Among the tools included are focus and exposure control, zoom in/out, and gradation settings such as tone balance, gamma curve, and threshold. Other menus allow you to fine-tune highlights, shadows, and contrasts to your liking. The Canon plug-in module FS works on Mac OS 7.5 or higher.

Image editing with Photoshop LE

扫描的样片:左边是标准曝光和标准色彩，右边是自动曝光和自动色彩平衡。很明显，使用标准的色彩效果很好，自动色彩平衡反而把颜色搞得不正了.
