GRLife Pro v1.42: film grain in the X half’s manner, fine or coarse

We redid the film grain the way Fujifilm’s X half does it: the same amount in highlights, mid tones and shadows, so you see it on a bright sky or a white wall too; on the luminance only, with no colour specks; and the same for every film. Its strength and size are fitted to the X half’s grain; none of Fujifilm’s data is used. New this time: a choice of grain size.

Two red wooden beach chairs seen from behind with two people sitting in them, a grey sea and sky beyond, the whole picture carrying visible coarse grain — Film grain set to High coarse, shown at one third. Rendered on a computer with the camera’s own algorithm; the photo was not taken with a GR.

What’s new

The same grain in highlights, mid tones and shadows: a bright sky or a white wall gets grain too, not just the shadows.
On the luminance only, with no colour specks; colour and black-and-white films get the same grain.
New grain size: Off / Low fine / Medium fine / High fine / Low coarse / Medium coarse / High coarse. Fine grain is tight; coarse grain is larger and shows more.
The level is still kept per film; the size is one for all films and is kept when you switch off.
Each photo gets newly made grain, with no repeating pattern anywhere in the frame.
ADJ 1.7: the film grain you assign to ADJ offers the same seven options, and RAW development lets you pick a size for that development only.

Six settings side by side

The same pale wall at 100 %: fine grain above, coarse below, low, medium and high from left to right.

Six close-ups of a pale blue wall labelled Low fine, Medium fine, High fine, Low coarse, Medium coarse and High coarse; the grain grows from left to right and is larger in the lower row — Grain rendered on a computer with the camera’s own algorithm.

On a black-and-white photo

The same black-and-white street, off on the left and High coarse on the right (shown at half size). The bright wall and road get grain too.

Two identical black-and-white street scenes with people walking past bollards; the left one is clean, the right one carries coarse grain all over, on the bright wall and the road too — Grain rendered on a computer with the camera’s own algorithm.

Where to set it

MENU → GRLife Pro → Film texture, first row, Film grain: Off, Low fine, Medium fine, High fine, Low coarse, Medium coarse or High coarse. ▲▼ pick a row, ◀▶ change it.

The camera’s Film texture page: five rows, the first one, Film grain: High coarse, highlighted

How to upgrade

Generate a new firmware in the firmware store and install it as before.
Open MENU → GRLife Pro → Info: when the second line reads v1.42 you are on the new version.
With a film bay film in use, pick the grain level and size under GRLife Pro → Film texture.

Good to know

You will not see the grain in live view; it appears in the saved JPEG.
It applies to film bay films only.
Supports GR IIIx 1.60 / 1.70 and GR III 2.10 / 2.20; confirmed on a GR IIIx with 1.70.
Installing unofficial firmware carries risk: keep the stock firmware so you can go back.
