[秋後算帳] 高ISO?冇有怕

本帖最後由 passerby-b 於 2018-5-8 13:54 編輯

今次去沙巴,入熱帶雨林影相,真係黑漆一片,經常要用到ISO6400
不過,今日的器材加軟件,用到咁ge ISO,真係冇有怕,
下面三張相都係用ISO6400 影,可以做到冇乜NOISE得來又濕

頭兩張係A6500
尾嗰張張A7R2

A6500 真係好勁,除咗搵雀慢之外,咩都贏哂7D2

遲D上一D本來係爛照,用PS CC救番出來的,俾你睇睇﹗

下面拍的是 Temminck's Sunbird, the data for the photo are:

@ F5.6, 400mm, Aperture Priority, 1/500 sec., ISO 800 Auto

第一張係raw直出,只係resize from 6000 to 1200

第二張係raw, cropped to 2776 and then resize to 1200

第三張就係用ps cc 搞過哂至出的,分別可大了

揾雀慢就死啦。。
我都有個 MC-11, 放 Canon 鏡落部 A7 玩,郁得唔慢,但每次都要諗幾秒先 ready, 點影活動野呀?
