几张395的黑白雪景

哎，人家这个4X5中幅黑白层次的丰富真是我们自己数码做出来的没法相比的。还得多看看这些片子，我们黑白的才能进步。

学习！

这次395跟陈先生学了不少。把自己按快门的频率降低了很多。

支持黑白。摄影的另一种境界。

画质很细腻啊

为了仔细研究陈先生的作品，特意买了一个Graphic Monitor （Viewsonic VG1930wm)。 发现原来的laptop看到的东西损失了很多。 那几张黑白的真的层次很丰富，高光，暗部很多细节。

Speaking of B&W, I use Tri-X and Fuji Acros for my 4x5. I believe digital capture has different spectral sensitivity curves of these characteristics in wavelengths vs. "panchromatic". In general, CCD takes affect to violet and blue light and very insensitive to yellow and green, and virtually not at all brilliant to red if you do straight conversion to B&W. Panchromatic films are excessively affected by influences of visible of light including ultraviolet radiation. Therefore they produce in varying shades of tone B&W relationship in all colors of natural light. For Digital capture, I don't mind carrying a "minus-blue" filter (#12) to the scattering that happens on those blue wavelengths. Thanks.

说出了数码在色彩上的局限，长见识了。
