各位師兄~~~小弟有事想請教一下~~



上面係一張用85 1.8 @ f1.8 既 100% crop
大家見到有明顯紫邊

其實睇相都唔覺既, 不過我手痕想改番正
點知set極都唔得


例如呢張我用DPP, 較左100, R 同 B 都係中間, 冇 colour blur (其實我完全唔知呢幾個setting 邊個打邊個!)

曾google一輪
有人話用photoshop得~~~
點解我用DPP唔得呢?
係我SETTING有問題?
定係呢隻係 lateral CA 所以改唔到?

色散係 chromatic aberration, 喺 NR/Lens/ALO 尾二

係呀~~~我有較呀!
但佢有幾個slide bars
我唔知邊個打邊個
我用default 既"100"
R 同 B set 左係中間
但係都冇效果! (上面第二張)

我都唔識用
不過R 同 B set 左係中間，會唔會等於無料到？有無試過slide下？

[william_yeung19]

h0001244 師兄, 即刻試下!~~

呢張係R同B都較到去左邊


呢張係R同B都較到去右邊


結論係, 冇分別!
有冇修圖達人可以教教路呢?~~~~=)

[h0001244]

I can see the difference, if you focus very closely

R同B都較到去右邊
left-white & right-black has lesser purple fringe

R同B都較到去左邊
left-black & right-white lesser purple fringe


but seems the software cannot help you to solve out the 85mm 1.8 CA problem

呀~~~我明師兄講咩喇~~~
真係有D分別, 不過真係好少好少~

因為其實我記得, 好耐之前用kit鏡既時候
係真係correct到紫邊
可能呢隻lateral CA, DPP 搞唔掂.......

用 photoshop 搞啦！

多謝師兄幫手
我一路都冇用photoshop~~~等我再研究下先`~~
請問是否用lightroom?
