Two new black-and-white films: HP 400 and AC 100
Many of you asked for more black-and-white films, naming HP5 and Acros. Here they are.
Two films join the black-and-white group. Like the TX films, they are not fitted to a LUT: we computed the film and the print from the spectral sensitivity and development curves the makers publish. No firmware update needed.
The pictures are simulations computed the way the camera processes the image, not camera shots.
HP 400
Simulated from the spectral and development curves in Ilford’s HP5 PLUS technical information: shot at ISO 400, developed normally and printed on soft paper. The classic street black-and-white, with moderate contrast, gentle highlights and wide latitude. It leans towards blue, so skies stay lighter, and under warm light it comes out a little darker than TX 400.
AC 100
Simulated from the spectral and development curves in Fujifilm’s NEOPAN 100 ACROS II data sheet: shot at ISO 100, developed normally and printed on a harder paper. Clean and crisp, with mid-to-high contrast and fine mid-tones. It is sensitive to red and weaker in blue, so blue skies print darker and skin lighter on their own, no filter needed.
Shooting tips
- Grain is not part of the film data: add it with the grain texture. Medium suits HP 400; light or none suits AC 100.
- Under warm indoor light HP 400 comes out a little darker than TX 400; +0.3 EV of exposure compensation helps.
- For a crisper AC 100, set Sharpness to +1.
If you own the GRLife Pro Film Collection, both films are already included at no extra cost:
- Open the film library page and download the film library again.
- Copy it to the GRLIFE folder on your memory card, replacing FILMS.GRF.
- In the camera’s film bay, load HP 400 or AC 100 from the B&W group into any position.
