GRLife Pro v1.41: the Edge light leak becomes Glow, with 20 light patterns

We redesigned the light leak. Edge is now Glow: 20 light patterns – bands, diagonal streaks, spots, a glowing corner, stripes and more – one picked at random for each photo and turned a random way. The light is added as brightening, so highlights never burn out to plain white and shadows are not lifted into flat patches.

A man at golden hour on a city sidewalk, a warm yellow band of light across the top of the picture — Light leak set to Glow. Rendered on a computer with the camera’s own algorithm; the photo was not taken with a GR.

What’s new

The light leak option Edge is renamed Glow: Off / Glow / First roll.
20 light patterns – bands, diagonal streaks, spots, a glowing corner, stripes and more – one picked at random for each photo.
Each pattern is also turned a random way (as shot, half a turn, mirrored left to right, mirrored top to bottom), and two photos in a row never get the same one.
The light is added as brightening: it never burns out to plain white, and the shadows are not lifted into flat patches.
A camera set to Edge gets Glow after the update. First roll is unchanged.
ADJ 1.6: the light leak you can assign to ADJ now offers Off / Glow / First roll.

Off and Glow

The same street: Off above, Glow below. A warm, pale wash spreads from the top, and the bright parts keep their detail.

The same daytime street twice: no leak above, a warm pale wash from the top below, more orange at the top right — Light leak rendered on a computer with the camera’s own algorithm.

Every photo is different

Four photos, four patterns: a glowing corner, a low band, a soft spot and two spots. You never know which one you will get.

Four daylight photos: a warm pale glow from the left of a tree-lined avenue, a faint warm band along a pebble beach, a soft pink glow on the right of a white-sand beach, two pale yellow spots over a city crosswalk — Light leak rendered on a computer with the camera’s own algorithm.

Where to set it

MENU → GRLife Pro → Film texture, fifth row, Light leak: Off, Glow or First roll. ▲▼ pick a row, ◀▶ change it.

The camera’s Film texture page: five rows, the fifth, Light leak: Glow, 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 v1.41 you are on the new version.
With a film bay film in use, set Light leak to Glow under GRLife Pro → Film texture; a camera set to Edge is already on Glow.

Good to know

You will not see the leak 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.
