※ 引述《PlayStation3 (超级喜欢于小文)》之铭言:
: 43R通篇在讨论录影的事情
: Firmware update:
: 4K Recording (IS compatible)
: High Speed and Slow motion Mode (240p or 120p)
: New Codec with different recording mode (24p,25p,30p,60p)
: Motion Film (I don’t know what it is exactly but it has something to do with
: a freeze picture functionality and choose to move what you want on the
: picture).
: They didn’t confirm all yet but about a similar S-log mode than the Sony one
: but they didn’t talk about it and how it would help grading for the cinema
: industry.
: And others stuff that i didn’t have time to check yet.
: I saw the 4K 24p and 30p mode, they was also other 4K mode but it was already
: the end of the Beta test. For sure this new update firmware doesn’t add
: anything, Olympus confirm 2 times that it was already there but not ready to
: be release because they needed to fix few issues. They add also new
: functionality for the pictures mode but i was not interested, only the video
: part. It’s possible that they release the new firmware by the end of this
: month
S-log是增加录影宽容度的方法
用比较特别的gamma曲线来记录更多的亮暗部细节
目前单眼具有这项功能的仅有 A7s跟GH4
一般来说,使用log模式拍摄可以得到至少10档以上的宽容度
GH4的10档是最少的
附带ㄧ提5D3影片的宽容度大概只有8,9档
专业的电影机的卖点就是log模式
这也是一般产品线涉及电影机的厂商不愿意下放log模式到旗下单眼产品的理由
这次A7s搭载sony在高级机种才会有的s-log2,也是A7s的热卖的原因之一
但用这种高宽容度模式拍出来的东西对业余玩家的意义有限
因为拍出来的画面是非常灰的,必定要靠后期提高对比
令外,以Sony A7s为例,使用log模式时 iso会被限制在1600,这对不习惯用减光镜录影的玩家是不切实际的
