GRLife Pro v1.29: grain more like film, faster playback
Until now the film grain matched a negative scan at 100 %, but on a phone, looking at the whole photo, it was too fine to see. GRLife Pro v1.29 adds the larger, uneven grain clumps of a negative scan, so a whole photo looks like film even on a phone. Film softness and grain are also more than twice as fast, so the wait for playback right after a shot drops from over 4 s to about 2 s.

What’s new
- Film grain now has the larger, uneven clumps of a negative scan. They show most in flat areas such as sky and walls, and give a whole photo a film look even on a phone.
- At 100 %, the fine grain is the same as before.
- Film softness and grain are more than twice as fast: with both on, a photo now takes about 0.2 s instead of about 0.5 s (measured on a GR IIIx 1.70). Pressing playback right after a shot now means a wait of about 2 s instead of over 4 s.
- No settings to change: your grain level stays as it is.
The same sky, on a phone
Left the v1.28 grain, right v1.29: an even fine sand on the left, soft patches of lighter and darker grain on the right.

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 v1.29 you are on the new version.
- Take a shot with film grain on in a film bay position, and look at the whole photo on your phone.
Good to know
- Grain works in the film bay positions, with the same Off / Low / Medium / High levels as before.
- 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.
