Rollei Ortho 25 Plus 黑白 120 底片

The sharpness on this 120 roll is incredible—edge details in my architecture shots came out crystal clear even at 25 ISO. Grain is virtually nonexistent, and the tonal range handles both bright highlights and deep shadows beautifully for such a slow film.

The contrast is amazing for landscape work—those sharp edges really bring out detail in tree bark and stone textures. I've been shooting at box speed with a yellow filter and the negatives are incredibly crisp.

The fine grain on this stuff is unreal—edges stay razor sharp even when I push the contrast in printing. Loaded a roll for some architectural shots and the tonality handled the brick texture beautifully.
