film scanner 負片模擬

終於有時間scan 負片比較一下
基本上就這次要模擬一次沖哂店出片的方法
用片是kodak 160 vc
sample (某家fdi沖哂店)

一張是日景(早上)

一張是室內
以上兩張我覺得那家已scan得非常好了~
好
現在就要模擬了
先scan一次片頭~
再經過+-曝光測試後得到全黑白片頭的數值是
master+0.4
red-0.2
green+1.1
blue+1.7
然後兩個sample都使用這個基準(即用scan as slide ...再用photoshop反轉影像)得出來的效果
左係fdi 中間係片頭基準scan 右係minolta負片自動scan

顏色中用minolta的負片已很好
比想像中好
留意fdi那家是會將contrast加大
而用片基的嚴重偏藍

而室內問題則比較少
3張中片基的sample的under了

之後就是模擬fdi了~
得出來的結果
左係fdi  右係minolta負片自動scan
在photoshop中對照再執出來的 (片基的沒有做了)

左係fdi  中係片基 右係minolta負片自動scan
[img]http://www.max33.net/upload/scantest/F1020026.jpg[/img][img]http://www.max33.net/upload/scantest/manul_base06_ps.jpg[/img][img]http://www.max33.net/upload/scantest/auto_negative06_ps.jpg[/img]
可見要模擬其實是不難的
結論是負片自動比較好...
可能是片基出錯的問題
當然模擬fdi的是為了經驗
而跟據當時的燈光(我眼所見)的情況下
這兩張應該更加貼近環境
左為fdi 右為minolta負片自動scan經我的修改
[img]http://www.max33.net/upload/scantest/F1020023.jpg[/img][img]http://www.max33.net/upload/scantest/auto_negative03_max.jpg[/img]

最後一張是沒有在對照情形下修改
左是fdi 中是用片基scan 右是ps過後的情形

小弟才疏學淺
只上只係玩玩下
發現自己要學既野仲有大把~(岩岩被人點醒)
大家當係睇下笑下算啦
我要認真學Colour Management !!!
