Photography light meter application

Does anyone know if the lumen sensor on the Diamond is accurate enough to make a good light meter application for use in photography?

I would assume no, but I certantly dont know for sure.

found this one it wil be possible http://www.clickapps.com/moreinfo.htm?pid=18788&section=

it has light meter build in

I'll have a play and see - I've got WaterLevel installed which gives an indication of brightness on the sensor, and I've got a Sekonic lightmeter which i can use to compare the two.
I suspect that the TD's meter is nowhere near accurate enough over the whole spectrum...

Let us know the results, would be interesting.

The water level light meter is what inspired me to ask. It seems fairly consistent, but have no real way to see if it's accurate.
If it is a light meter application that also included stuff like DOF calculators etc... would be slick.

I bought the one that WvanWaas had linked. It workes great on my Onmia i910 thanks guys

Light Meter Accuracy for Diamond
There is an app - Water Level - that I use that is reasonably accurate at measuring lumens, but very directional using the small front camera - but it works well enough for OHSE evaluations. Whether its good enough for photographic use I don't know - and then you still have to develop the translation from lumens to ISO's f-stops etc

I am writing one.
The app is called Light Meter, Vesion 1.01a is currently available on the market.

Stand-alone GPS status display?

OK, now I know that the GPS is software driven - i.e. you cannot manually turn it on or off. However, is there a package that will activate the GPS on the phone, and show a status display of the satellite constellation and how well or poorly the receiver is picking them up?
I'd grab SiRFtech, but the phone uses the Qualcom chipset, not the SiRF III chipset

there are tons of gps utils... for fast switching gps on and get fix search for the small prog "GPS test" i´m running version 1.04 don´t know if thats the latest

apps
well, even if it is from SirfTech, all GPSs support the NMEA protocol. if the app you showed also supports NMEA, then this is fine.
I normally use CruxView (attached), which is also quite simple, has some nice functions (+a dedicated SiRF section, which I'm not touching )
/edit: I guess your app supports NMEA - at least I see it listed in the menubar!

Thanks folks Much appreciated Should make figuring out what's wrong with the GPS on my TP2 a little easier - takes forever to get a lock, and even then bounces in and out like a chicken on a bungee rope on acid - and it only started doing that this week, three weeks after obtaining the phone, no less!

gps is a miracle
never got it to work right...never more than 3 sats outside on both kaiser and rhodium, inside no chance!
a week ago i installed gps test and navigon and i got best gps, fast fix and can navigate through my house!

[Q] finding relative co-ordinates of a android device

i want to know my device location(co-ordinates) with respect to some known location(that could be location found by the device itself in the first) inside a building.
i used location services like network provider and gps but they are in accurate.

That is about as accurate as you will get. And plus, if you are using GPS on a phone such as the GS4, you get the latitude and longitude to about 8 decimal places, which should more than accurate enough, unless you are trying to measure centimeters of movement.

Agreed with tanishq.dubey that theres no real way to get more precise than GPS, unless you want to use the accelerometer to detect movement and calculate its displacement that way, but I'm not sure about the accuracy of the accelerometers, nor exactly what data they would give you to work with, so it may not be a viable option, but you can definitely try. Otherwise, use GPS, and a little bit of math (

GPS craps out after 5 minutes of activity - think it may be a rogue app

So I'm rooted on 6.0.1 and in the past few weeks I've noticed that while using Google Maps Navigation, the GPS cursor will freeze in location and not update even though I've physically moved far far away. It's been a pretty frustrating problem as I haven't been able to find a smoking gun just yet.
It seems to occur 4-5 minutes after I start navigation. Not sure if it's tied to navigation or there's something else that's occurring in the background that's causing the issue. I downloaded (and bought the pro version) of GPS Status Toolbox to see what was happening. When the error occurs, I lose GPS signal and it will take anywhere from 4-12 minutes to get the next GPS lock (which doesn't stick). It effectively breaks all apps that would use the GPS.
Here's a screenshot of the GPS Status Toolbox with 20 satellites acquired but still no fix on position - and this is after it's been trying to find a position for several minutes.

I've tried clearing the cache with no improvement. I've tried deleting the google maps app data which allowed it to work again for a few minutes before freezing up again.
I've looked at the app permissions for location but nothing has jumped out at me as something that would create an issue.
I thought maybe there was some hardware interference in my car but my girlfriend's S5's GPS works perfectly while mine is floundering.
Any thoughts on how to troubleshoot this? I tried booting into safe mode and the GPS seemed to work fine for the 10 minutes I was using it. Also I had used it for a month prior (before the 6.0.1 update) and the GPS worked just fine - so I don't think it's a hardware issue.

Running apps in potrait on landscape units

Hi all.
I have an RSNav in my car running Android 9, I also have modded headlights that can be controlled via the bluetooth app on my phone. I thought that I'd be able to install the app on my RSNav and control it that way instead of being phone dependant, however the app doesn't work properly on the head unit.
The app is 'Morimoto XBT RGB' and while their hardware is top quality the app is really poor, and it hasn't been updated for about 4 years. When trying to run this on the unit, it does load up, but it's clear that it isn't designed for landscape devices as the title displays all stretched and pixelated. On the main screen it has a color wheel, but this doesn't work properly; it gets cut off and the dot on the wheel glitches all over the place, as does the tone selector. The icons at the bottom also get cut off and you cannot scroll down on the RSNav. I've not even bothered to try and connect via bluetooth.
Picture of the main screen:

"lightbox_toggle_sidebar": "Toggle sidebar"
}
I've not got a huge understanding of all this. The RSNav has Android 9, but it's kind of a cut down version and doesn't have all features/options, say, a phone would have. It has nothing to do with screen orientation in the settings, for example. And I've had issues with other apps such as "Poweramp" - it threw an error when I tried to set music folder locations (but I managed to get around it) and people seemed to point out that "something" was missing it depended on.
Anyway I did try some screen orientation apps to try and force it to run in some kind of portrait mode but nothing worked.
So my question is: is there any way to get this working or is it a lost cause?
I wish Morimoto would update the app since a lot of people have had many issues with it, it's outdated, and it has a low rating because of this. But at the moment it stands neglected.
