Filming - A full test on a focal-plane camera is now filmed from behind: back open, lens on at its widest aperture and pointed at your light, in a dark room. Only light that came through the lens and the shutter reaches the phone. A quick test, and capping, are still filmed from the front with the lens off. Leaf shutters are filmed from behind for both tests. - Filming from behind, hold the phone upright or sideways, whichever is more comfortable. - Before each test, a short card shows how to set up the camera and the phone. The setup screen and the recording screen both say which side to film from. - If you have used ShutterDoc before, a short note explains the change the first time you open it. - The setup guide is shorter, explains the two tests first, and has a new drawing for filming from behind. Focal-plane shutters - At the flash sync speed and slower, from 1/60 down, each reading now times every part of the frame on its own, so light that changes during a long exposure no longer throws it off. With no flash sync entered, this starts at 1/30. If the light reading disagrees, the reading says so. - Fixed: in dim light, speeds around 1/8 and slower could read far too short, with a "Mirror light removed" note. Noise in a dim picture was being taken for light from the mirror. - A quick test can now measure the sync speed itself with no slower shot: 1/60 on a camera that syncs at 1/60, 1/30 on one that syncs at 1/30. Enter the flash sync on the setup screen. - A full test now needs a slow speed to measure the faster ones against: 1/30 on most cameras, slower on one with a slow flash sync. It starts ticked, and you can swap it for any slower speed. - A gate a little off square no longer brings up a "Camera tilted" warning. Setting up - The setup screens are shorter. What to do stays on screen; the reasons are behind the ⓘ buttons. - Capping opens with a short "Before you start" card, including which way to hold the phone. The example maps have a colour scale, and Saved runs is at the top of the screen. Other - When a test on one of your cameras is finished, closing the readings takes you to that test on the camera's page. - Exports now include the frame rate each reading was filmed at.

Leaf shutters - Quick test now supports up to 1/125. - Readings from about 1/30 to 1/125 are more consistent in steady light, and the accuracy table in the app is updated to match. - A test of only 1/60 and 1/125 no longer warns that nothing is slow enough. 1/60 now sets the reference. - For older shutters, a switch above the speed grid shows the old-style dial: 1/25, 1/50 and 1/100, with 1/250, 1/300, 1/400 and 1/500 to pick from at the top. - The "Blades not fully open" note is gone. Readings at 1/250 and 1/500 already allow for blades that are only part open. Readings saved before this update keep the note. Saved camera profiles - The camera form asks for the film gate, the speed dial on a leaf shutter, and which way the curtains travel. Each can be left as Not sure. - Speeds you type in for a camera, like a Compur's 1/25, are now kept with it. Hold one on the speed grid to remove it. Cameras you already have offer the extra speeds they've been tested at. - A camera remembers its film gate, and the test screen shows it instead of asking again. - The camera form now says when a name is already taken. Medium format - Fixed a bug where film gate aspect ratios would persist between modes. - 6×4.5, 6×6 and 6×7 can now be chosen for the speed test as well as capping. The light reading, and Measure inside the guide only under Advanced, use the chosen gate's shape, and a square-on medium format gate is no longer reported as a tilted camera. Testing - A full test starts with no speeds ticked, so it fires only the speeds you choose. - Recordings now stop after 3 seconds by default, down from 6. Set your own under Recording length. If you had already changed it, your choice is kept. - Left-handed mode: in landscape, a button at the top of the recording screen moves the controls to the left edge. - The suggestion to turn the phone sideways now appears only where turning it helps. - In a quick test, the note beside the extra-speed field says how to get to a full test. General - Readings that were discarded due to poor conditions no longer impact the final verdict. - Streamlined reading export files. - Streamlined warnings to use less technical language.
