噢, 原來你concern呢樣, 咁我可以話.......無計!!
以我作為快x美的長期客戶的經驗所得, 就算你出返個最窄最通用的sRGB, 佢出來的相也不一定(甚至係不可能)跟你的file一樣, 很簡單, 因為佢唔會有你個色域檔麻, 除非你同店主好熟, 熟到佢願意為你save個色域入佢個腦到專登幫你出相. 這做法好似我估除非廣告公司, 否則都好少會幫你咁做.
因為正如上個post提到, 就算話作sRGB, 都未必個個一樣, 佢富士跟機那個又未必一定係hp那個IEC61966-2.1, nikon自家那個又唔同.....
加上, 佢print 相的時候, 部魔術手會set返sRGB出, 還是用cymk出呢, 又唔知, 而cymk比sRGB更窄, 所以出來效果一定唔同. 這道理同樣應用在自行print的情況, 所以一般色管公司, 如colorvision都會出埋 cal print 的色管產品, 如: printfix pro.
佢係一個分光儀, 你用printer print 張色版出黎, 係上面一格格咁話返比電腦知甚麼紙質上的顏色是怎樣的, 佢就會為printer在這種紙質下出個profile, 到時你用這返呢隻紙就可以出返跟你個file一樣的output啦, 當然呢個野係低檔野, 五千幾有找, 上次上去北光吹水時, 佢話高檔次講緊係幾萬到幾十萬不等, 分別在於分辨色版細仔能力囉.
所以, 你要output跟file一樣, 最好就係自己print啦.....

Billyting C-hing, I see and thank you your conculsion.
I concern about this issue because I am going to do scanning some 婚紗相and they took many years ago. You know I cannot take again because both of us are old
I wish that I can keep the record perhaps need to do print out again in the future.
By the way, I upload 2 images to [OTHERS] in Contax Club Forum, please take a look if you have time.
Again, thank you very much your value information and suggestions.
Have a nice day !
