Beschreibung

TrueDoF-Pro is a major step forward in working with depth of field. Specifically designed for working professionals, the app offers features, versatility, customisability and no-fuss ease of use to make it the ideal tool — a tool that simply does its job (superbly) without getting in the way.

And it’s a tool that works the way YOU want it to work:

* Directly set any relevant quantity you like, even the near and far limits of DoF.
* Lock any input in place; vary any other input.

Want to “work backwards,” whereby you specify the depth of field you’re after, and have the app tell you what aperture and focus distance you need? Couldn't be easier. Enter what you want directly; get instant results.
Want to lock in a particular far limit of depth of field (e.g. as a cinematographer, would you like to lock in the far end of a set)? Slide the far limit pointer to your desired distance, and hit its lock button. Freely change any other input you like.


A key (and unique) TrueDoF feature is the option to include the effects of diffraction in the calculation of DoF, giving a much more accurate indication of how sharp the image will be (see the article "Image Sharpness vs Aperture" at www.georgedouvos.com).



A partial list of features:

* Elegant, interactive, easy to read interface, with both graphical and numerical display of data

* Fast, no-fuss input; real-time output
* Unprecedented input options: Want to specify a far limit of DoF? Or a near limit? Now you can.
* Lock any input (aperture lock not available on iPhone 5s)
* Option to “work backwards” — set your desired depth of field, see what focus distance and aperture you need
* Hyperfocal function — lock your far limit at infinity
* Option to include the effects of diffraction
* Optional visual indication of the limits imposed by diffraction
* Customisability of numerical readouts (show, hide, display distances or blur size, display front and rear DoF as distances or %)

* User-definable focal length presets for the scroll wheel's rapid selection buttons, for super-fast selection of YOUR lenses

* Support for all formats up to 8x10in

* User-selectable distance scales

* Distance units changed directly on main screen by tapping m/ft button

* Optional "distance snap" function

* Optional input of focus distance via keypad

* User-selectable aperture scales (reading to f/22 or f/64)

* Aperture slider snap to half or third stops (user selectable)

* Easily switch between settings for different cameras: a simple slider to set a blur spot diameter (circle of confusion); no tedious listing of camera models
* Blur spot diameter is displayed on the main screen, so you won't find yourself working with the wrong setting

* Facility to specify wavelength, for use when shooting in the infrared or ultraviolet parts of the spectrum
* Visual indication of wavelength on the main screen
* Context specific help
* Comprehensive User Guide



A note on intended use:


In any DoF calculator, you specify a sharpness criterion — the blur spot diameter. All calculations reference that value. 
In some situations (e.g. landscape photography) it is best to work quite differently: Specify the distances to the nearest and furthest objects that you wish to appear sharp and, from that, determine the focus distance and aperture that will give the SHARPEST POSSIBLE IMAGE (not simply one that meets your preset sharpness standard, which may not be the best possible). For that, there is only one app: OptimumCS-Pro, the unique optimum camera settings calculator (this is NOT simply a DoF calculator that "works backwards").

And if, in your landscape and architectural photography, you would like to achieve insanely huge depth of field, with astonishing image sharpness, try FocusStacker. Take the guesswork out of the focus stacking technique and achieve remarkably consistently (and excellent!) results.

Neuheiten

Version 6.0

This update adds optional readout of image blur for objects at the extremes of depth of field and at focus (where image blur will be non-zero if you opt to include the effects of diffraction).
Why would this be useful? After all, image blur at the extremes of depth of field should simply be your specified circle of confusion. Well, not if you focus beyond the hyperlocal distance.
Some landscape photographers place greater emphasis on image sharpness for far objects (the horizon or, say, a line of trees on a ridge) than for near objects. They reason that the eye/brain expects distant objects to be sharp but can tolerate a wee bit of image blur up close. So they focus a little beyond the hyperlocal distance. Well, now you can have a readout of image blur and better judge where you would like to place focus.
By the way: You'll have the far limit pointer at infinity, but don't lock it in place. Locking it engages Hyperfocal Mode, which you don't want in this case.

The update also adds more flexible options with regard to switching off numerical readouts, for those who prefer a more minimalist interface — one that relies on the use of analog scales.

If you're new to TrueDoF-Pro, don't forget to check out the Links page where, among other things, you will find links to articles on image sharpness, depth of field, etc. You may end up looking at such things a little differently.

Die perfekte Kontrolle über die Schärfe 👍 SUPER

Diese App ist wirklich besonders! Erstens ist hier das UI genial einfach und extrem bedienerfreundlich gelöst. Die Regler sind beweglich und miteinander verbunden, man sieht sofort die Veränderungen in den Skalen plus alle relevanten Werte bzw. Ergebnisse. Zweitens kann man hier die Lichbeugung (Diffraction) mit in die Berechnung einfließen lassen, und drittens kann man einen Unschärfedurchmesser vordefinieren, um den eigenen Vorstellungen von der optimalen Schärfe gerecht zu werden. Es gibt einen ausführlichen englischen Text mit anschaulichen Kurvendiagrammen dazu - lesenswert!
Ansonsten einstellbar: Brennweiten-Rad mit 1mm-Abständen, Vorwahl von bis zu 9 Festbrennweiten. Hyperfokale Distanz mit nur einem Tap, Durchmesser des Unschärfekreises in Micrometer, Wellenlänge des Lichts, Ergebnis in Distanz oder Prozent, Blendenskala bis 22 oder bis 64, 1/2 oder 1/3 Blendenstufen, Distanz in "m" oder "ft", Berechnung der Diffraction ja/nein, Anzeige der Begrenzung durch die Diffraction ja/nein, auf Wunsch "magnetisches Schnappen" der Entfernungsdaten auf gerade Werte, Voreinstellung der Entfernungsskala mit Betonung auf "Nah", "Mittel" oder "Weit".
(Es gibt eine Lite-Version zum Ausprobieren)
Für mich ganz klar eine der besten Apps im Store und ein MUSS für Fotografen, die die Kontrolle über ihre Schärfe haben wollen - 100% Kaufempfehlung!!!

Intuitiv und simpel

Habe ne ganze Reihe DOF-Tools ausprobiert, am flottesten zu bedienen und einfach handzuhaben ist TruDof.
Bin jetzt auf die pro Version umgestiegen.
Was mir besonders gefällt
Ist dass der Schärfeverlust bei zu kleiner Blende mit eingerechnet wird - top!
