Product Highlights
Overview
Ilford Ortho Plus is a medium speed black and white negative orthochromatic film that is especially well-suited for continuous tone copy or reproduction work, as well as for half-tone, technical, and forensic applications. It has a nominal sensitivity of ISO 80/20° when exposed under daylight conditions, or ISO 40/17° when exposed under tungsten lighting, and can be developed in standard black and white chemistry. Additionally, since the film is only sensitive to blue and green light, it can be handled under red safelight conditions and developed by inspection for precise processing control. Its high-resolution, fine grain structure and long tonal range also make it ideal for producing faithful reproductions of original artworks and documents, as well as for photomicroscopy.
Ilford Ortho Plus是一款中速黑白負片正色膠片，特別適合連續色調複製或複制工作，以及半色調，技術和法醫應用。 在日光條件下曝光時，其標稱感光度為ISO 80/20°，或在鎢光照下曝光時ISO 40/17°，並可用標準黑白化學品進行開發。 此外，由於膠片只對藍光和綠光敏感，因此可以在紅色安全燈條件下處理，並通過檢查進行精確處理控制。 它的高分辨率，精細的紋理結構和長長的色調範圍也使其成為製作原創藝術品和文件以及光學顯微鏡的忠實複製品的理想選擇。

Comparing 4x5 film to medium format, if you push this film to 3200, the grain should appear less apparent in the 4x5 compared to the medium format, but still there. This is why large format photography is appealing, because when the film is pushed, the grain structure is much finer overall because you are shooting an image onto a larger medium.
比較4x5膠片和中等格式，如果將此膠片推到3200，與中等格式相比，4x5中的顆粒應該不太明顯，但仍然存在。 這就是大幅面攝影很吸引人的原因，因為當推動電影時，由於您正在將圖像拍攝到更大的媒體上，所以整體結構更加精細。

Review
Slow, but ultra-fine-grained - this is the film I choose for my b&w still-life's!
慢，但超細粒 - 這是我為我的黑白靜物選擇的電影！

備註: 1. 也適合拍人像, 用以強調皮膚的線條.
2. 也適合拍風景, 因為綠色的植物會較亮.
