photos taken with windows 8 tablet through the image widget are only 0.3 mp
photos taken with two different windows 8 tablets using the image widget are reduced to only 0.3 mp; i.e., when a photo is taken by selecting the camera icon the photo size is reduced to minimum specs. In contrast the photo sizes are approx. 5 megapixels (2592x1944x24) when the windows 8 default camera app is used. So one can work around this limitation by taking the photos outside of Roam and then selecting via the "from folder" option. However, taking photos within Roam is simpler and thus reduces the number of steps when training non-tech-savvy field workers.This type of problem (that is reduced photo quality) was also an acknowledged bug in ArcPad on Windows 8 tablets. As per their usual practice, the ESRI developers declined to fix the bug. Although maybe it is a problem with Windows 8 on tablets. I also noticed that when using the image widget in Roam that the camera orientation doesn't respond to the tablet's orientation, that is if you flip the tablet 180 degrees and the screen rotates as expected, the photo will be upside down if taken through Roam.
Strange. I have seen this too on my Windows 8 machine but not on Windows 7. I will take a look at some stage, hopefully it is a easy fix.

So the better solution is to detect the max resolution however it seems that is harder then I would like at the moment (changing the C++ library that I use and compiling against Direct X). For now the work around is to add a camera_res option to roam.config and set it to your resolution:
camera_res: width, height
Note: If you set the wrong resolution the camera just doesn't start.
Awesome! That workaround is more than manageable. I look forward to trying it out when the next version is released.
Still encountering issue on Windows 8.1
Investigating if it is an OS issue or Roam issue.
Pictures I take with the inbuilt camera app are working ok, inside Roam images are saving as 424x240 despite the roam.config file set to higher resolutions.
Tried 1280,720 to exactly match the resolution native app is saving at however still saving at very low quality/res.
In their infinite wisdom Microsoft removed the ability to change the camera resolution in windows 8.1: http://answers.microsoft.com/en-us/windows/forum/windows8_1-pictures/windows-81-camera-app-more-options/33f9e7ab-77dd-4d23-ab1e-c33a472f8f17
Issue likely a mix of Roam not saving right and inbuilt app being useless now.
did anyone ever have luck getting this to work, that is setting a max resolution for the camera in the roam.config file? If I do not insert a camera res option (camera_res: width, height) then the photos are just taken at the minimum resolution but when I do try to set the option I just get a message saying "Could not start camera"
I have been setting the width and height to the values that I see on photos taken with the built-in Win 8.1 app (e.g., camera_res: 2560, 1440). I have tried on a 2nd tablet and get the same result
currently testing with v 2.4.2 and wondering if anyone has had any success using the camera via the Roam widget in Windows 10. By success I mean either being able to take full size photos by default or by entering in the tablet's resolution in the config file as Nathan suggested and being able to have the camera start. I cannot seem to chose the correct camera res to add to the camera_res option, i.e., camera_res: width, height. I have tried using the width, height that is reported on the photos taken with the windows camera app but that doesn't seem to work.
because the issue closed, perhaps there is a solution that I just can't get right.
any suggestions?
@rjwillson are you able to run Roam from source? I can add some extra logging to help debug this. I just tested on my Windows 10 install and it returns the max size for the camera.
@NathanW2 that is great news that it works on your Windows 10 install. Does it return the max size for your camera by default with no changes to roam.config? I have 2 new windows tablets coming this week with fresh Win 10 installs that I can test on.
Roam from source: Yesterday I tried unsuccessfully to get set up to run from source following your instructions at http://roam-docs.readthedocs.org/en/latest/dev-guide/Building/
details are below and are off topic for the post
as per your instructions:
I installed Visual Studio C++ 2008
I have 64 bit QGIS installed at OSGeo4W so I changed path in scripts\setenv.bat
When I then ran scripts\setupdev.bat it generated errors and some invalid zip files ("py2exe.zip" and "setuptools-20.10.1.zip")
So I manually installed py2exe, easy_install, and pip
When I then ran package.bat the error message indicates that there is no module named setuptools
