GRLife Pro v1.32: a Med-large date stamp, and the right turn for upright shots

A user told us the Large date stamp was too big and Medium a little small. GRLife Pro v1.32 adds Med-large in between, and fixes the stamp turning the wrong way when you turn the camera right after a shot.

Four sizes

The same photo with each stamp size, true to scale: Small top left, Medium top right, Med-large bottom left, Large bottom right.

The same landscape photo four times, with a Small, Medium, Med-large and Large date stamp in the bottom right corner — Stamps rendered on a computer with the camera’s own algorithm, as an illustration. Photo: Danish Prakash / Unsplash.

What’s new

The date stamp Size row is now Small / Medium / Med-large / Large. Med-large is 1.5 times Medium: the figures are about 4.65 % of the photo’s short side (Medium 3.1 %, Large 6.2 %).
Medium stays the default, close to what a film camera’s data back printed.
The old Auto, which looked exactly like Medium, becomes Med-large; if you had picked Auto, the menu now shows Med-large.
Fixed: turning the camera right after a shot could print the stamp the way the next shot was held. The way you hold the camera is now noted the moment you press the shutter.

Turn the camera right after the shot

Three shots in a row, upright, level, upright the other way, turning the camera right after each. Top row: before; bottom row: v1.32.

Top row: three stamps facing the wrong way; bottom row: all three in the bottom right corner, reading left to right — The stamp used to be drawn once film grain and the like were done, about 5 s later, by when the camera had turned. Photos: Clay Banks, Danish Prakash / Unsplash.

Getting started

Generate a new firmware in the firmware store and install it as before. Open MENU → GRLife Pro → Info: when the second line reads v1.32 you are on the new version.
The film library file on your SD card stays as it is.
Go to GRLife Pro → Date stamp → Size and step through the four sizes with left and right.

Good to know

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.
