cold tone 这是一张粗放，冷调。去一点青色（比如减黄，粉红色各五个单位），多曝10～20％，就会是很好照片。 本帖最后由 pangmfkiev 于 2016-7-2 21:11 编辑

理解很正确。下面测试图（含30秒，45秒，60秒，和90秒）中，在自然光下看，从30秒曝光图中，找出两个匹配灰格（需用两种棱形灰卡）
A05M，C10M10Y（需曝光24秒，f11；实际用曝光12秒，f8）。在45秒图中，是C15M15Y（需曝光28秒，f11）。60和90秒图中也都有一个匹配灰格。 先放一张用（A05M）校正（妈妈和女儿合影），感觉没有必要再去红色。 图上灰格标志，只是示意，有助于讨论。 quote]whiterabit 发表于 2016-7-2 11:40  [/quote] 我的理解不知道对不对，只要是能够匹配到色块，就是正解，不同的是色调。 [/quote] |

我碰到同一曝光图（比如10秒）两个匹配色块（我有两种不同棱形灰卡），都是正确解（多解），不同曝光时间测试图还能给岀其它解（比如从20秒图）。我第一碰到的：冷色和暖色。第二次又碰到三解：暖，变冷uote]whiterabit 发表于 2016-7-1 19:38
非常好的教程。请教一下。 1、工具是教材里面配套的还是单独买的？ 2、菱形灰板假设在一次试纸上匹配到两个以上的小色块，怎么查表？ [/quote] |

如果在美国ebay上打上UNICOLOR DUOCUBE MITCHELL，进行搜索，就会发现有两家在卖都是旧货，好象有的虽旧，但是没有用过。如果完全一套，就有一个Duocue，一个㪚射镜，一个帮助识别灰格的棱形灰卡，两个说明书，负片，正片放印

first trial (too red)由于底片条件和初始值相差很大，左边大方块没有中灰格，只有在右边的找。根据下面黄表进行校正（比如从20秒曝光图找出灰格），我画了二个灰格，看C40M60Y，根据字母C：时间校正系数是1.6，那么 本帖最后由 pangmfkiev 于 2016-7-1 11:41 编辑

我觉的亚洲人肤色（如果皮肤比较白），用富士负片，多曝一，二档，相片上肤色显得白里带点粉红色。quote]晓巴 发表于 2016-6-30 09:27

这是用过曝三档底片，印的结果还可以。不同屏幕，看得结果可能不一样。从照片上看，16秒曝光最合时，脸上色彩对比，饱和度都很好。头发丝也看得很清楚。12秒的，感觉脸上色彩淡了一些。放大机上颜色通道粉红色减5个单位，实际上，给印出的照片增加粉红色。相机用基辅88CM加东蔡180mm。底片条件和定的初始值相差很远，需要很大纠正。
quote]晓巴 发表于 2016-6-29 11:58 刚开始放出这效果真不错 感觉16秒的曝光合适，但是有点奇怪的是12秒的反倒给人感觉曝光比16秒的还多。 还有，16秒 M-5 这张反倒比没减5的还红，是不是标写错了？ [/quote] |

我觉的不需要。书上说再来一张中心曝光。比如通过计算，颜色通道，光圈，时间都选择好，就中心来一下。这样对光强不圴有一个再校正。按理说，通过散射镜，光强度在整个放大区域是一样。实际操作时，能发现光强不均（分析曝光后测试相图）。自己感觉8x10放大，一般校正足够，放一张后，可徾调。如果放大于8x10寸，我觉的需中心曝光测试。否则，成本会上去。
quote]晓巴 发表于 2016-6-27 14:39 另外是不是可以根据第一张测试片的结果排除5秒、20秒和40秒三个曝光，用6秒、9秒、12秒、16秒再做一次测试片，以便更精确。 如果用新的曝光得到了更精确的测试片，是不是应该以新的曝光组合多做几张测试片，看看新的曝光组合是否稳定？ [/quote] |

在测试曝光时，这散射镜用于罩住放大镜头，这样光通过底片，和放大镜头后被平均化。当真正放大相片时，散射镜就不需要了。放大机的光通过自己光箱，被柔光化。
quote]晓巴 发表于 2016-6-27 14:30 曝光校色的事看明白了，多谢多谢 这个方法中散射光镜起什么作用？彩色放大机的光源已经是散射光源了，为啥还要另加散射镜？实际放大照片时还要不要这个散射镜？  |
