我頭先 用manual set 光圈先決 試過 f2.8 至 f4.7 影出黎既幾張相 ...
好易out focus 呀 同埋 好多粒粒咁.... 紅紅綠綠咁..... 細細粒

係咪有熱點呀?? 定係 死點 or 唔知咩事
頭先我用個 software 黎 check 部機既 死點無事架 ~
但唔知點解影d 相出黎會咁

[bb86]

Tell us more details about the pictures, eg. 光圈值,快門速度, ISO 速度, 曝光模式, 等等.

[youshii]

UM... 因為張張 唔同 所以...
全部都用 ISO 100 (以經係最細)
EV 就 唔超過 +1 我用 EV +0.3 +0.7 OR 0 都有
光圈大約 F4.7
快門佢自己DETECT 我用光圈先決呀...
但係 ~ 個D 粒粒 會因為黎D 野而發生嗎?
我見D 比較光 同 比較暗既地方就會出現.......
好似 綠綠 紅紅咁 D 粒粒...... 好似係雜訊咁 ~ 但係 雜訊唔係影D 比較暗既地方先會發生嗎? 我屋企算幾光 BOR.......

仲有一個問題 : 我用 AUTO OR CUS SET 既 WHITE BALANCE 呢 個 LCD 睇落 好偏藍呀? 係咪有事架部機....... 都去唔到好白既....... 係咪都藍藍地

[trent]

Those "dots" are noise, and u have nothing to do with them.
If there hot pixel it will show in photo as some very distinct and bright color dot.

[youshii]

嘜唔係影 夜景同比較暗既野先有 noise 既咩 我係屋企開哂d燈 好夠光 都係d 白色面 上 都有 noise?..... 咁有咩解救呀? oh... 同埋我影出黎既相 ... 十張有九張 都 out focus 既? 我以經無咁點震架喇 隻手....... 係 lcd 到睇 同 按半下快門 對焦個時 都好清架 係影 完 過左落部機到睇 就 out focus 喇 ~ 好慘呀 ~ 無張見得人既... 黎d 生活照 無黎由要用埋腳架影架麻 點算好呢! 係咪有d咩問題呢

[Velsper]

相機:F100
快門:1/4-1/10 (check了兩三張)
光圈 ..
iso 200 (是f100的)


現在可以對症下藥~
noise多可以理解 <<<下次set做iso100吧
鬆應該係手震吧~
>>我以經無咁點震架喇 隻手
係慢快門下,一點點的震動對相片影響相對較大

下次先看看相機的讀數吧 ^ ^
因為人眼太好了,相機卻不然.
(地鐵內的光只可到約f2.8 1/8秒@iso100)
快門太慢又不想落腳架可以用閃光燈

[Velsper]

ps
影靜物可以set做單點對焦 (大框框那個是 area af 區域對焦 )
這樣應可以較好控制對焦點

[youshii]

多謝你呀 velsper............... 係得幫我..
我想問下 我用auto mode... 黎影 佢先幫我 自動 set 做 iso200
咁我如果想係 auto mode 影 但 set 做 100 可以嗎?
and 我係 手動個到 試過 set 快門 做 1/90 1/125 比較快既快門 set 埋 ev 做 最大 ev+2 但係張相都係好暗 但又唔想用閃光燈 因為用左閃光燈 張相會好核突. 有一忽會好光 d 色會變左 好假咁... 如果 快門 set 做 1/90 set ev 做 0 即頭 係黑哂張相....... auto mode 影親都 幫我自動 set 做慢快門... 咁好易會有影響 而 out focus........ 我其實都想 set 快 d 個快門.. 令佢無咁易影響到........ 我想問 以你覺得 我係屋企黎d 環境 應該可以 set 快門同光圈做幾多同 ev 幾多先適合呢?....... 如果一定要用 auto mode 係咪無得解決頭先個問題呢 除左用閃光燈.......頭先你 check 我d 相 用 1/4 or 1/10 係咪算係叫做慢快門呀.... 同埋你叫我 先看看相機的讀數 意思係咪 check iso 快門光圈個d先呀 ........ sorry 問左你咁多野
thanks x 999999999999999999 velsper

>>我想問下 我用auto mode... 黎影 佢先幫我 自動 set 做 iso200

I think better use menual mode and set to ISO100

>>ev 做 最大 ev+2 但係張相都係好暗
em.. ev isn't use in this way. ev adjustmnet is only available in P/A/S mode. For example,if you use shutter priority(S),setting 1/90 and F100 gives you F2.8, ev+2 will not function because the largest aparture is only F2.8 (if ev+2 really exists,it should be changed to F1.4) and it can't adjust shutter speed (S MODE---shutter speed control by user)
aparture priority(A) actually did the same thing.


>>以你覺得 我係屋企黎d 環境 應該可以 set 快門同光圈做幾多同 ev 幾多先適合呢
^ ^since i don't how "bright" your home is so you better believe values that F100 gives you when you half press the shutter( aparture value and shutter speed)
try not to use ev adjustment at first.

set ISO to 100 to avoid that much noise
(I seldem use auto rec. mode--- not just on F100 only but all mechines)

PS
sorry for my poor english, if you have any problems i am glad
to answer you tonight ^__^

[bb86]

Yeah, using ISO100 at almost all the time is a good idea.

In such 慢快門 (1/4, 1/10), you have to turn the NR on to avoid generating noises in the photos and to put your camera on the table or somewhere to fix the position of it to avoid 手震. Using self timer will be better too.

Try to take the same photos again tonight in the same light condition to see if those help. :)

你意思係咪話係光圈先決 同快門先決既MODE 下
你SET 既EV 都係無用.. 部機會SKIP 左 .........

SET EV 做 0 係咪 就 叫做無用到架喇 ?

如果用快門先決SET 做 1/90 我試過影張相係全黑... 吸唔切光咁
1/1000 就緊加唔洗諗會影到野.. 係咪一定要開閃燈架.. 唔開就無得解決? 部部DCAM SET 做 1/90 都會咁架?

[Velsper]

>>意思係咪話係光圈先決 同快門先決既MODE 下

ev(explosure value) mean how "bright" is the environment .
since in metering, camera will determine the "ev" for you
if u "don't agree (you know, camera metering is not that accurate if the light is complex or much "white or black" area)
so u adjust the ev

example F100 suggest that it is 8ev but you think it is brighter ie 9ev
is better,u will set ev+1 to let F100 know.

>>SET EV 做 0 係咪 就 叫做無用到架喇 ?
yes

如果用快門先決SET 做 1/90 我試過影張相係全黑... 吸唔切光咁
1/1000 就緊加唔洗諗會影到野.. 係咪一定要開閃燈架.. 唔開就無得解決? 部部DCAM SET 做 1/90 都會咁架?
use the concept of "ev" each ev value F100 will suggest different
aparture and shutter speeds
eg. ev of 7 may gives
F2.8 1/15s = F2.0 1/30s = F4 1/8s ..........etc
in your case, the environment may be too dim
eg. ev 3
if you set shutter to 1/90
aparture cannot gives the "right" value (the largestis F2.8 only)
so the outcome photo will be dark.

if you still want to use 1/90 ,using flash is the only choice

[Hercules]

try a flash shot indoor and a bright outdoor shot, using A mode and ISO 100, see the noise is still visiable or not

velsper ,

>> in your case, the environment may be too dim

咁我想問下.. 其實係咪係一般屋企既室內燈(白色燈，唔係光管)，如果用上 1/40 OR 以上 1/125
既快門 唔開閃光燈.. 係咪一定會影到d相好黑 or 暗到 睇唔到個影像架?

只可以用 1/4 or 1/8 黎d比較慢既快門呀?

I think it depends on the environment ! (I am F100 user) For example, now when I go to the Chinese restaurant and take the photos, I will use the manual mode, set the white balance, then let the DC to select the aperature and shutter, then even I won't use the flash, the photo is bright enough ! If you don't have tripod, I won't suggest you use the shutter at such slow speed like 1/4 or 1/8 since your hands will shake ! Usually 1/20 or 1/30 is better ! But remember, if the environment is dark, you better use flash la !
