結合經典外觀與現代品質，ILFORD DELTA 400 Professional 是一款高速黑白負片，採用 Ilford 的 Core-Shell™ 晶體技術。它產生高銳利度的影像，並具有細緻且均勻的顆粒結構。
在標準黑白化學藥水中沖洗時，其標稱感光度為 ISO 400/27°，非常適合手持攝影及光線不足的環境。這款多用途底片可設定在 EI 200 至 EI 3200 之間，具有寬廣的色調範圍和寬廣的曝光寬容度，讓您可以在沖洗時進行增感或減感，以維持一致的對比度。
儲存與處理： 請在微光下裝片與卸片。未曝光的底片請以原始密封包裝儲存在冰箱中，溫度為 13°C（55°F）或更低。為避免冷藏過的底片產生水氣凝結，請在打開包裝前讓底片回溫至室溫。曝光後請盡快沖洗底片。保護已沖洗的底片免受強光照射，並儲存在陰涼乾燥的地方。
The Core-Shell crystal tech really shows in the grain structure—even pushed to 800, the midtones stay remarkably smooth for a 400-speed film. I've shot two rolls in harsh midday light and the sharpness on my medium format negs is exactly what I hoped for.
Shot two rolls of this on a bright coastal day and the Core-Shell crystal tech really shows in the grain structure, even at 400 speed. The sharpness held up beautifully in the mid-tones where I usually lose detail with other high-speed films. I've already got three more rolls in the fridge.
Finally a high-speed B&W film that doesn't sacrifice sharpness for grain. The Core-Shell crystal tech really shows in the mid-tones, and I was able to push it a stop without losing detail in the shadows.
