    Not really an App:

    Why not a lensNany-ish piece of hardware that would turn any tablet into a digital view camera? There would probably need to be some sort of app to go with it.

    There are only three types of mounting flanges; too big, too small and wrong thread!

    Re: Apps for Large Format

    I try to simplify when possible.

    My two most used lenses in the field seem to be a 150mm and a 210 mm (in 4x5). By prefiguring the correction,: the 150mm needs ~1/3rd stop more exposure for every inch beyond 6 inches and the 210mm needs ~1/4thmore for each inch beyond 8".

    When working inside with table top set-ups maybe I'll figure it out more closely.

I think it's primarily the tilt aspect that makes it more interesting for large format users than the typical depth of field app. It's mainly intended for landscape photography use cases. In addition to hinge distance calculations in provides the height of the in-focus window (wedge span at infinity), and intersections if you choose to put the hinge distance below the ground level (useful for longer lenses).

    You can find more info about it here: http://www.lumariver.com/#LumariverDoF

    It's not a free app, but I can assure you I have put plenty effort in it, and it's pretty well documented

    I've attached a couple of screenshots below for a Nikkor-SW 90/8 lens, used with and without tilt (to separate screens within the app). The concept is based around interconnected scrollers, when you move one the others follow (if necessary) according to the depth of field formulas. Here's a brief 90 second video showing the scrollers in action: https://www.youtube.com/watch?v=WOQYFlHCz70&rel=0
    I've just released a new update (v1.0.4) of this which includes a lens database. You can always enter your lenses manually as before if you're using something exotic (which is common in the large format world), but if you have one of the common Rodenstock, Schneider, Fujinon or Nikkor lenses you can pick it directly from the bundled database.
