Hi all darkroom boys and girls,
My F-Stop Printing Calculator App is now live and available for iPhone, iPod Touch, iPad and Android gadgets.
It has some advantages over the web version in that it is portable and it has a red light mode allowing it to be used, with care and Aiplane mode switched on, inside the darkroom where you need it.
Best of all, it is free, has no ads and no in app purchases.
Digitaltruth Photo have built it, so you can find it on their site. Click the icon.
You can also reach it via my support pages for the web app by clicking here.
