C'mon - there's gotta be some programmers out there that are also photographers (or vice versa)!

[beckywc]

This would be sweet.

[slyjosh]

I would like to see a light meter using the camera, but a dof calc would be cool too.

Use the DOF preview button.

[swong13]

Use the DOF preview button.

The DOF preview button does not calculate hyperfocal distance. Also does not work well in low light conditions. Kinda hard to see what's sharp with the aperture closed down and your viewfinder is dark. I was also never very good at using the preview button even when I had a lot of light.

I had made a request in the past for a DoF calculator but still no luck.

The website www.dofmaster includes calculators for the Palm OS (I used to have it on my Palm T2. Worked great!), iPhone, and an online calculator. They also have the charts. I really miss having it on my Palm and really wish it was available on my Storm. I have written to DoFMaster to request a Blackberry version but have not gotten a response.

The DoF calculators at DoFMaster are free but I would be willing to pay for one that worked as well as their Palm version did.

Chaoss-

Thanks. That works! I am able to calculate Hyperfocal distance by typing in f-stop, camera type, and focal length.

I am trying to figure out the usage of the chart at the bottom. It looks like it provides alternative f stops and the resulting depth of field. I don't understand what looks to be a second set of "far" distances.

Thanks for the effort that you put into this!

Cheers for this )

[keaton]

I used to program in visual basic when I was like nine and now am a photographer... Although I don't think my limited vb knowledge will help here

I'm going to download what chaoss posted and see how it is!

Seems to work well, assuming the data was transferred correctly! Nice job! Here's a clickable link to make it easier for anyone on the mobile forums. http://widgety.biz/DOFcalc/DOFcalc.jad

yes, the table provides alternate f stops with rows for near,far,dof, and hyperfocal. I just threw this in to fill space on the screen, let me know if you want something different or other changes

The application, as it is now, does everything that I need it to do.

Thanks, again!

Are there installation instructions for the DOF calculator onto my Storm 9530?

[Chaoss]

from your phone, just download the app using the link above. The app will be saved in the downloads folder.

I did make one additional change, the focal length was not saving when exiting the app...it now saves properly

[richardseeley]

Yes, download successful. The calculator works great. I like the alt f-stops. I will be using this in the field. I am a photographer, mostly wildlife:
richardseeleyphotography.com,
I could have used this calculator on sat when I was photoshooting osprey in Maine.
thank you very much.

do you have any other cool apps for BB and photographers?

Rich Seeley

no, but what else are you looking for? I'd be willing to work on any app that's useful

[PDR447]

I'm looking for a DoF app for my new tour and unfortunately this doesn't seem to be working. I can edit all the details(focal length, distance, format, etc.) but the only way I can get it to actually calculate the DoF is to exit out and re-open the app.

any chance of getting this updated for the tour? also maybe adding some cinema formats?

thanks!

[wolfpeterson]

Is there an alternative to the native camera app?

The auto white balance when using the flash is always wrong, but it's a pain going through the menus to go and change it before taking the photo...

It would have been good if RIM had made shortcuts to those things (geotagging, WB, quality).

DOF CALCULATOR
I have tried to download the DOF calculator. I received a message stating the following

Error starting DOFcalc:
Class
.net.rim.device.api.ui.Virtual Keyboard not found.

Does anybody know what this actually means. Secondly is this software only available for the Storm.

Thanks

[Chaoss]

here's the non touch screen version DOFcalc


@PDR447
the F-stop and Format/CoC values can be edited on both the touch & non-touch screen versions

[bwcomputers]

Great, was just about to ask about that non-touch version.
Thanks for the work you have done.

[AkaChuck]

You don't really need an application to do simple math calculations like a DOF calculator. A simple JavaScript file will work.
To make it work on a Blackberry device, simply copy contents of the file below from <HTML> to </HTML> and save it to a file for example DOFCalc.html file and then copy it to the BB device (or any device) via USB cable.
For example I copied it to backberry/documents/DOFCalc.html
and then open the Blackberry browser and open the file by typing in the location of the file in the URL
For example
file:///SDCard/blackberry/documents/DOFCalc.html
Blackberry is case sensitive and make sure JavaScript is enabled. Then Bookmark it so you can easily access it.
The calculator will calculate in feet, however, by changing one line of code in the HTML file feet = true to feet = false it will calculate in meters. Let me know if you have any issues.

I have this one, and btw thanks for the OS6 update.
