有無人用過d100加紅外線filter拍相呢?

[micros]

有。
你想知o的咩﹖

[whiskas]

我都相請教呀。係咪set黑白就可以呢？還是有其他setting?

[hsc]

micros兄
我有以下問題:
1點取景呢(我打算用部dc,set到差吾多焦距,當雙相反光用)
2.點對焦
3.點測光

d2c兄
拍人像啊
52mm我問過2百幾元一片啦

[micros]

想構圖準o的﹐要用腳架。
先構好圖再上 filter。
對焦同測光要自己試。
枝枝鏡o的對無都唔同﹐無記錯除o左有特別色散糾正o既鏡﹐原有對焦指示唔可信。
如 nikon af 20mm f/2.8﹐應用對焦距離比正常時前少少。
加上收o的光圈就保險o的。
曝光都係﹐試下試下咁﹐digital 就好用好多。

如可以 search 下﹐有o的公司幫人改機﹐ir filter 取代原先 low pass filter﹐咁佢就可以手持﹐以下係其一。

各位
我剛剛買了
52mm/200元


點解人地拍的是黑白

我是紅色呢

[hsc]

我今天只在家中拍,未掌握到
只見紅影啊

[tyuen]

I prefer to use dc for IR / Near IR photos as it can be viewed directly from the LCD for composition...

[micros]

係紅色Ｏ既﹐ＰＳ　轉　ＢＷ　啦。

tyuen兄
我用g2就吾多得啦(用lcd取景,吾知是否吾識set)

d2c兄
我想不關事掛? 我要試多d

micros兄
明白了,明天有空要試試

各位
我用人眼看過,此片東西也不是全不透光
我看到少少紅色的影啊....(今天中什強光時)

[hsc]

吾好意思
我買了片野都吾過24小時,中間8小時睡了覺,
今天好太陽會把去拍拍

>>我用g2就吾多得啦(用lcd取景,吾知是否吾識set)

What's the problem?

1. You may have bought near IR filter instead of IR filter.
2. The other may convert to B&W.

[tyuen]

>>紅外線 經 過 filter 之 後 ,
係 咪 會 變 左 visible spectrum,
and mostly RED color only ???
和 CCD 係 咪 淨 係 sensitive to visible spectrum 架 ???


It seems that hsc has bought the near IR filter. This blocks mostly visible light and allow near IR (very deep red) and IR to the CCD.

The CCD is sensitive to some range of UV and IR. But it is usually blocked by low pass filter before the CCD as mentioned by micros. This makes the exposure time of IR photos longer unless you do a surgery (say from the link of micros.)

lcd看不到東西啊
