GRLife Pro v1.43: classic film grain is back

The last update, v1.42, switched the grain to the X half’s manner. Some users told us they preferred the grain we had before, so it is back as “Classic”: little grain in the highlights and more in the shadows and mid tones, coarser on high-speed films, with faint colour specks on colour films, as in v1.41 and earlier. The X half-style fine and coarse grain stays too: three kinds to pick from.

Rendered on a computer with the camera’s own algorithm; the photo was not taken with a GR.

What’s new

Film grain has a new size, Classic: Low / Medium / High classic, after fine and coarse.
Classic is the grain until v1.41: little in the highlights, more in the shadows and mid tones, coarser on high-speed films, clumps on high-speed black and white, faint colour specks on colour films.
The X half-style fine and coarse grain is unchanged.
The level is still kept per film; the size (fine / coarse / classic) is one for all films, and your current choice stays as it is.
ADJ 1.8: the film grain you assign to ADJ gets the three classic levels too, and RAW development can use classic for that development only.

Three kinds of grain

The same patch of platform at 100 %, all at High: fine on the left, coarse in the middle, classic on the right. Classic is softer, with a few colour specks.

Three close-ups of grey concrete labelled High fine, High coarse and High classic; the classic one is softer with a few colour specks — Grain rendered on a computer with the camera’s own algorithm.

It follows the film

Classic grain follows the film’s speed. The same patch, all at Medium classic: ISO 200, ISO 400 and ISO 1600 colour films, and an ISO 1600 black and white film.

Four close-ups of concrete labelled ISO 200, ISO 400, ISO 1600 and B&W ISO 1600; the grain grows coarser with speed and the black and white one has no colour — 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 … High coarse, Low classic, Medium classic or High classic. ▲▼ pick a row, ◀▶ change it.

The camera’s Film texture page: five rows, the first one, Film grain: High classic, 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 v1.43 you are on the new version.
With a film bay film in use, set Film grain to a classic level 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.
