C'est une application universelle pouvant fonctionner à la fois sur iPhone et iPad.
L'originalité de l'application est son interface graphique qui permet à l'utilisateur de visualiser la profondeur de champ sur toutes les valeurs de diaphragmes sans avoir à modifier un paramètre.
L'utilisateur peut alors se rendre compte rapidement de l'influence de son réglage, et des autres possibilités qu'il a pour gérer la zone de netteté.

DoF Viewer is an application used to calculate the depth of field (DoF) as well as the Angle of View (AoV).
It also calculates the hyperfocal distance, the near and far boundaries for acceptable sharpness (near focus and far focus).
The application is Universal, it means it can run on both iPhone and iPad.
The originality of the application is its graphical interface that allows the user to view the depth of field values on all the aperture range without having to change a new setting.
The user can quickly realize the influence of its setting, and other possibilities it has to manage the depth of field.
---------------------------------------------------------------------------------------------------------------
Grâce a une fenêtre "glissante", DoF Viewer donne la valeur de l'hyperfocale, la profondeur de champ (DOF), la distance minimum et maximum de netteté (Near Focus, Far Focus) pour chaque valeur de diaphragme et cela sans toucher à aucun bouton!
Simplement avec un "swipe" verticale sur la zone graphique.
Nouveautés pour la version 2.12
* Mise à jour de la base de données incluant les derniers appareils disponible
* Choix entre une interface foncée ou claire
----------------------------------------------------------
The depth of field is calculated in "real time".
Thanks to a "moving" window, DoF Viewer gives the value of the hyperfocal, the depth of field (DOF), the minimum and maximum distance of acceptable sharpness zone (Near Focus Far Focus) for each f-stop. And this without any button!
Simply with a "vertical" swipe on the workspace.
New features in version 2.12
* Camera database updated with latest models
* Choice between a dark or clear interface
---------------------------------------------------------------------------------------------------------------
La version 2.12 améliore l'interface utilisateur
Il n'était pas toujours facile de sélectionner la distance avec le "slider" de l'iPhone.
La nouvelle version ajoute un "picker" pour sélectionner plus rapidement la bonne distance.
De plus l'échelle de distance n'est plus liée au type de focale permettant ainsi un plus grand choix.
----------------------------------------------------------
The 2.12 version improves the user interface
It was not always easy to select the distance with the iPhone "slider".
The new version adds a "picker" to quickly select the correct distance.
Also the distance scale is no longer related to the type of lens allowing a wider choice.
---------------------------------------------------------------------------------------------------------------
Un "swipe" horizontal permet d'accéder au calcul de l'angle de vue et de l'angle de champ.
L'angle de vue (Angle of View) est donné en degrés il représente l’angle couvert par l'objectif (horizontal, vertical et diagonal)
L'angle de champ (Field of View) est donné en mètres il correspondant à la distance couverte par l'objectif pour une distance donnée.
----------------------------------------------------------
A "horizontal" swipe provides access to the calculation of the angle of view The angle of View is given in degrees it represents the angle covered by the lens (horizontal, vertical and diagonal) The field of view is given in meters (feet) it represents the distance covered by the lens for a given distance.
---------------------------------------------------------------------------------------------------------------
Un mode "Expert" est disponible pour calculer le cercle de confusion
Ce calcul permet de s'affranchir du critère de Zeiss et permet d'estimer la profondeur de champ par rapport à l'agrandissement de l'image finale.
Pour plus d'information, vous pouvez consulter le fichier d'aide
----------------------------------------------------------
An "Expert" mode is available to calculate the circle of confusion
This calculation eliminates the criterion of Zeiss and can estimate the depth of field with respect to the final image (enlargment).

La version iPad permet de comparer en même temps deux types de configuration différentes
L'utilisateur peut donc rapidement estimer le rendu de la profondeur de champ sur le tirage final et se rendre compte de l'impact de la distance d'observation sur la perception de la profondeur de champ.
--------------------------------------------------
With The iPad version it is possible to compare two different types of configuration
The user can estimate the rendering of depth of field on the final print and realize the impact of viewing distance on perceived depth of field.
---------------------------------------------------------------------------------------------------------------
Cette vue en forme de "barre graphe" visualise la profondeur de champ pour toute la gamme d'ouverture La partie supérieur du graphe (barre verte) represente la distribution de la profondeur de champ pour la gamme d'ouverture choisie.
Une barre verte supérieure à 100% indique que la profondeur de champ est supérieure à 100 mètres (infinie) On identifie rapidement l'augmentation ou diminution de la PdC en fonction de l'ouverture grâce aux repères 100% et 50%.
50% representant une PdC divisée par 2 par rapport à la PdC maximum affichée. La partie inférieure (barre rouge) represente la zone de netteté situé devant la distance de mise au point. On identifie également rapidement l'augmentation ou diminution de cette zone en fonction de l'ouverture grâce aux repères 100% et 50%.
---------------------------------------------------------------------------------------------------------------
Another view is used to display the depth of field in another way !
This "bar graph" view shows the depth of field for the entire range of f-stop The upper graph (green bar) represents the distribution of the depth of field for the aperture range selected.
A green bar above 100% indicates that the depth of field is greater than 100 meters (328 ft) (infinite) The user can quickly identify the increase/decrease of the Depth of Field according to the f-stop thanks to 100% and 50% indicators.
50% representing a depth of field divided by 2 with respect to the maximum displayed DoF. The bottom (red bar) represents the acceptable sharpness zone in front of the focusing point. The user can also quickly identify the increase/decrease of this zone according to the f-stop thanks to 100% and 50% indicators.

You have bad resolution and setting for Phase One IQ180. This back have 80 mox in normal mode or 20mpx in sensor+ mode. Same is in Iq160,140. Look at ducumentation on phaseone.com
RépondreSupprimerHello,
RépondreSupprimerThanks for your feedback, some confusion between the full resolution mode and the sensor mode. It will be fixed in this release (v2.12)

Excellent app. Please translate to Spanish. The comparative mode is a good idea, but sometimes it's confusing. It would be great, have the option to choose, show one or two cameras. Thank you.
RépondreSupprimerExcelente app. Por favor traducir al español. El modo comparativo es una buena idea, pero a veces es confusa. Sería estupendo, tener la opción de elegir mostrar una o dos cámaras. Gracias.
Hello Billalabeitia,
SupprimerThanks for your feeback. I agree the comparative mode is quite confusing. It was initially designed to compare two CoC setup with the same camera but as you can choose different cameras, the result is confusing. The sensor size/angle of view could be different... result is like comparing pears and apples ! I'm working to improve this mode. If you are interesting you can follow the next update (and more) with twitter :
DoFViewer

Hello,
RépondreSupprimerI bought the application but not the Sony DSC-RX100. You could include it in the next update.

Hi Javier,
SupprimerThanks for purchasing my application.
A major update is on going but it will take a couple of week to be released. I will of course update the camera database with all the new cameras on the market (including Sony DSC-RX100!)

Arnaud
Hello!
RépondreSupprimerThanks for the app! It's beautifully made and I love it.
There is a small error in the ipad version though. When comparing cameras, the far DOF limit in the overview pane at all different aperture are swapped. So the Dof for camera 1 is actually the dof limit for camera 2 and vice versa. The total dof therefore also doesn't add up with the figures.
Please fix this as it is confusing.
Thanks!
Ray
Hi Ray,
SupprimerThanks for your feedback. The comparative mode in the iPad version is quite confusing. It was initially designed to compare two CoC setup with the same camera but as you can choose different cameras, the result is confusing, the result is like comparing pears and apples !
Moreover as I don't use the same scale for the figures, it could happen that the figures are not coherent with the "real" DoF as you mention in your feedback.
I am currently working on an update with a new feature ... it should be solve the problem. Still some couple of week to be released !

Arnaud K.
Dear Arnout,
RépondreSupprimerThanks for your response. I really appreciate it.
I understand the comparative mode was initially to compare CoC setups, and that comparing two cameras is in many ways like comparing apples and oranges. Different scales does not help there either. But actually the scales look pretty ok to me. It is also not the problem I was referring to.
Let's take an example:
I compare a Canon 5d Mk ii (1) and Canon 450d (2). (which is how I found out about it; but it replicates to other cameras and comparisons)
CoC setup is both set to normal. Focal distance is 50mm. Distance to object is 2.00m.
In the overview pane I get different DoFs for different apertures as it should.
At f/2 it says
near dof 0.19m far
1.91m 0.12m 2.06m
1.94m 2.10m
front back
0.09m 0.10m
0.06m 0.06m
Does does not add up for the "far" limit. Actually the two numbers are flipped. The far limit for camera 1 is 2.10m and for camera 2 it's 2.06m. So the other way around. Only then the total DoFs for camera 1 and camera 2 add up to respectively 0.19 and 0.12. Also the front and back numbers match again.
So it's not so much an error in math but in presentation, and that is confusing.
But if you will fix it with a different setup in the new version then it should fix itself.
Just wanted to make sure you noticed the small error.
Best,
Ray
Hi Ray,
SupprimerThanks for the detailed description. It is clear now ... "far" limit numbers are swapped. It will be fixed in the next update. (you can already see it in the snapshot !) I also increase the resolution according to the range (it will automatically fit with 2 digits after coma -> in that case centimeter is used instead of meter ) 0.19m becomes 18.76cm .

Arnaud.
Hello Arnout!
RépondreSupprimerI use a Ricoh GR Digital IV for street photography. That camera, which is in your database, has a fixed 6mm lens. The focal-slider only allows me to choose 4mm or 8mm. How can I set the value to 6mm? Can I enter it somewhere?
Thank you very much for your help!
Hello Bernd,
SupprimerThank you for your interest. Unfortunately you can not set the value to 6mm. I'm sorry for that. I made the application to be easy to use with pre-selected lens (unfortunately it does not include the 6mm). It is an idea for the next update to include at least for all the camera with a fix lens, the corresponding focal. I will try to include it in the next update but i can not give you a release date for the moment.
Regards
Arnaud
