Version 1.5 of Viewfinder Preview is now available in the iPhone App Store. The major change for version 1.5 is the film emulation renderer has been completely rewritten to improve its speed and efficiency. There had been reports of film emulation being slow on earlier iPhone models and the it was quite battery hungry. This was especially true of the plus size models. The new version of the renderer has fixed the speed issues and should be much more battery efficient. In addition to the film emulation rewrite there was an additional optimisation to the histogram generation. The plus size model phones were taking longer to generate the histogram. This change ensures the generation time is consistent across all models.
Outside of the optimisations there were a number of other issues addressed. A bug where the Rangefinder mode would not always set the correct zoom while taking a photo has been resolved and a memory leak in the Journal has been fixed.
Finally Sony cinema camera formats have been added to the film/sensor format presets.
Version 1.4 of Viewfinder Preview is now available in the App Store. This version includes a new version of the rangefinder mode. In addition to displaying a box for the selected focal length it will include other focal lengths that are included in your focal length menu. These will be greyed out so they don’t interfere with the view too much but it does mean you get to see them without changing focal length. See above to see an example of this mode while framing a pineapple.
An issue with UI responsiveness on early iPhone plus models while using film emulation has been resolved. There are still performance issues with the iPhone 6 plus. We will be looking to resolve these in a later release.
Version 1.3.3 of Viewfinder Preview is now available in the App Store. This update includes storing the ISO, aperture and shutter speed stop increments with each film format setup. It also fixes a couple of bugs related to the storing of various data with the film format setup. And finally a crash bug has been fixed when an image fails to load.
Previously the last app update I wrote about was version 1.3 so I will detail all the changes since then below.
In version 1.3.1 an option was added to stop resetting manual exposure mode on application restart and a crash when sharing photos on the iPad was fixed.
In version 1.3.2 a crash that occurred while deleting photos from outside the app was fixed. Also I increased the maximum focal length and film format sizes.
In addition to Viewfinder Preview I have also written a darkroom timer app for the iPhone. I wasn’t happy with any of the timer apps currently available so I wrote my own. It allows you to build your own development recipes with individual timers for each stage of the process. Because I don’t want to be messing about with my phone in the darkroom it is designed to be simple to use (touch anywhere on the screen to start/stop a timer) and easy to see the current state of the timers at a glance. You can find out more here.
The app is available on the App Store for free.
