Product Description
ILFORD FP4 PLUS is a medium speed, all-purpose black & white film
with very fine grain and outstanding sharpness.
It has superb exposure latitude above and below its ISO 125,
(meaning it can be both push or pull-processed). This makes FP4 PLUS a highly
capable film for most photographic subjects, scenarios and lighting conditions.
It particularly excels at highly detailed subjects in good indoor and outdoor lighting
conditions and is therefore an ideal film for portraits, fashion, street, product
photography, landscapes and architecture.
FP4 PLUS can be processed in a wide range of different developers using
spiral tanks, deep tanks and automatic processors.
產品描述
ILFORD FP4 PLUS是一款中等速度，多用途的黑白膠片，
具有非常細的紋理和出色的銳度。
它具有高於和低於ISO 125的極佳曝光寬容度（意味著它可以是推或拉處理）。
這使FP4 PLUS成為適用於大多數攝影主題，場景和照明條件的高性能膠片。
它特別擅長處理室內和室外光線條件下的高度細節，因此是人像，時尚，街道，
產品攝影，景觀和建築的理想拍攝對象。
FP4 PLUS可以使用螺旋罐，深罐和自動處理器在各種不同的開發商處理。
---------------------------------------------------------------------------
FP4 Plus is robust and will give usable results even if it is overexposed
by as much as six stops, or underexposed by two stops.
FP4 Plus功能強大，即使曝光過度多達六次，或兩次曝光不足，仍可提供可用的結果。
FP4 Plus sheet film is coated on 0.180mm/7-mil polyester base with an anti-halation
backing which clears during development. It is available in a wide range of
standard sizes. The emulsion faces the user when sheet film is held in the position shown.
FP4 Plus薄膜塗在0.180毫米/ 7密耳聚酯基底上，並具有抗光暈背襯，
可在開發過程中清除。它有多種標準尺寸可供選擇。 當薄膜保持在所示位置時，
乳劑面向使用者。
Best results are obtained at EI 125/22, but good image quality will also be obtained at meter settings from EI 50/18 to EI 200/24.
EI 125/22獲得最佳結果，但在EI 50/18至EI 200/24儀表設置下也可獲得良好的圖像質量。
---------------------------------------------------------------------------
---------------------------------------------------------------------------
MAKING LONG EXPOSURES
For exposures between 1/2 and 1/10000 second, no adjustments are needed for reciprocity law failure. When exposures longer than 1/2 second are given, FP4 Plus, along with other films, needs to be given more exposure than indicated by a meter. Use the graph to calculate the increased exposure time which should be given once the measured time is known.
對於 1/2 和1/10000 秒之間的曝光，互易律失效不需要進行調整。 當曝光時間超過1/2秒時，FP4 Plus和其他膠片需要比米表顯示更多的曝光量。 使用圖表計算一旦測量時間已知，應該給出的增加的暴露時間。
---------------------------------------------------------------------------
DEVELOPMENT TIMES
For manual processing in spiral tanks and deep tanks, the development times are based
on intermittent agitation. Where continuous agitation is used for manual processing
(as in a dish/tray or with some types of developing tank), reduce these times by up to
15%. For use in rotary processors without a pre-rinse, reduce the spiral tank development
times by up to 15%. A pre-rinse is not recommended as it can lead to uneven processing.
對於螺旋罐和深罐中的手動加工，開發時間基於間歇攪拌。 如果使用連續攪拌進行手動
加工（如在碟子/托盤或某些類型的顯影罐中），請將這些時間縮短多達15％。 對於沒有
預漂洗的旋轉式處理器的應用，可將螺旋罐的顯影時間減少15％。 不推薦預沖洗，因為
這會導致加工不均勻。
---------------------------------------------------------------------------
PROCESSING AT DIFFERENT TEMPERATURES
FP4 Plus film can be processed over a range of temperatures.
Development at 20oC/68°F is recommended and the times are given
in the development times table. If development is not possible at 20oC/68°F,
the following chart can be used.
The chart is based at 20oC/68°F for a general developer, and can be used
to give an estimate ofodevelopment times at temperatures around 20 C/68°F
For example, if 4 minutes at 20oC/68°F is recommended, the time at 23oC/73°F
will be 3 minutes and the time at 16oC/61°F will be 6 minutes.
FP4 Plus膠片可以在一定的溫度範圍內加工。 建議在20oC / 68℉下進行開發，
時間在開發時間表中給出。 如果在20oC / 68℉時不能開發，可以使用下面的圖表。
該圖基於一般開發人員在20oC / 68℉下的溫度，可用於估算在20°C / 68°F左右溫度下
的開發時間
例如，如果建議在20°C / 68°F下4分鐘，23°C / 73°F時間將是3分鐘，而16°C / 61°F時間將是6分鐘。
---------------------------------------------------------------------------
CHARACTERISTIC CURVE
Note
The chart can only be used as a guide because different developers and processing techniques can vary the results.
注意
該圖表只能用作指南，因為不同的開發人員和處理技術可能會改變結果。

20oC/68°F with intermittent agitation. This curve is also representative of the 35mm
and sheet film formats.
FPF Plus Rollfilm在ILFORD ILFOTEC HC（1 + 31）中於20℃/ 68°F間歇攪拌8分鐘後開發。 這條曲線也是35mm和單張膠片格式的代表。
---------------------------------------------------------------------------
Safelight recommendations
Handle FP4 Plus film in total darkness. For very brief inspections during processing,
use the ILFORD 908 (very dark green) safelight filter, with a 15W bulb, fitted in a
darkroom lamp (such as the ILFORD DL10 or DL20). Do not allow direct lighting
from the safelight to fall on the film.
安全光照建議
處理完全黑暗的FP4 Plus膠片。 在加工過程中進行非常簡短的檢查時，
請使用安裝在暗室燈（如ILFORD DL10或DL20）中的ILFORD 908（非常深綠色）
安全燈過濾器和15W燈泡。 不要讓安全燈直接照明落在膠片上。
---------------------------------------------------------------------------
Agitation
Intermittent agitation is recommended for use in spiral tanks and deep tanks.
Continuous agitation is recommended in dishes/trays by rocking the dish/tray.
With spiral tanks, invert the tank four times during the first 10 seconds, then invert
the tank four times again during the first 10 seconds of each further minute.
Otherwise, follow the recommendations given by the processing equipment
manufacturer.
攪動
建議在螺旋罐和深罐中使用間歇攪拌。 通過搖動碟子/托盤，推薦在盤子/托盤中持續攪拌。 使用螺旋罐時，在前10秒內將罐翻轉4次，然後在每隔一分鐘的前10秒再次翻轉罐4次。
否則，請遵循加工設備製造商提供的建議。
---------------------------------------------------------------------------
Stop, fix, wash and rinse
For best results it is recommended that all process solutions are kept at the same temperature or at least within 5 oC (9 oF) of the developer temperature.
停止，修理，洗滌和沖洗
為獲得最佳效果，建議將所有工藝溶液保持在相同溫度或至少在顯影劑溫度的5 oC（9 oF）範圍內。
---------------------------------------------------------------------------
測試結果建議:
1. 感光度測試: ISO = 125 (淨濃度: 0.12)
2. 顯影時間測試: 取標準顯影時間 9分鐘 x 80% = 7分鐘
3. 調整顯影搖晃方式:
先搖晃 30 秒; 之後: 每靜置 25 秒, 搖晃 5 秒.

例子 1:
2018.05.15 10:30 a.m. 陰 33度
IOS 125 -> 64
camera: EBony RW45
Lens: 210mm
Bellows: 210mm
光圈: f22
測光:
zone 5 => 亮部: 2 sec, 暗部: 30 sec; 差 4 stop
暗部 zone 3 = 8 sec; 調整 = 25 sec
Dev:
HC-110
N+3 => 7分鐘 x (根號2) x (根號2) x (根號2) = 7x2.8 = 20分鐘
稀釋顯影比例: 1:63; 20x2 = 40分鐘
搖晃方式:
前一分鐘: 持續搖晃
之後每 2:45 搖晃 15 秒
備註:
a. 建議測光時除了將 ISO 減半之外, 可將暗部置於 zone 4.
b. 亮部與暗部的實際差距, 可能會比測得的更大.(大 1 ~ 2 stop 以上)
c. 稀釋顯影時, 可將顯影的藥水多調配一些, 以避免亮部在長時間靜止的情況下,
顯影不均而產生條帶狀的影像.
---------------------------------------------------------------------------
心得:
1. 將 IOS 125 設定為 64 來拍攝.
2. 正常顯影時間:
HC 110B 1:31 20度C 9分鐘 => 採用 80%, 設成 7分鐘.
3. 當亮部與暗部相差 5 stop (不包括) 以上時, 可使用正常顯影時間的 N 加或減 1, 2, 3
來處理. (說明: 測光時須配合 增加/減少 1/2 N變動值, 來補償暗部)
4. 承上, 並可配合: 稀釋顯影, 最大比例為: 1:255 來減少對比
