awesome idea!
just installed it, gonna test it soon.
Looks cool. My wife wants to know "how accurate is it"?
If you're the app dev, would like to know how it's calculating things. We're both university-trained amateur/hobby photographers and I'm a programmer, so i'm curious
It's quite accurate, but you have to understand the hardware limitations. This is a reflective light sensor, unlike incident light sensors used by companies like Sekonic. Stray light can put the sensor off by 2-3 stops.
The light sensor will output the amount of light detected in terms of lux. Using a few calculations, this is converted to an EV value. you can read more about this here: http://en.wikipedia.org/wiki/Exposure_value#EV_as_a_measure_of_luminance_and_illuminance
With the EV value, this gives us the current exposure of the environment. Given a user selected ISO and aperture, it is then easy to calculate the required shutter speed for normal exposure.

I smell spam.
Yep, definitely smells like spam around here.
You are kidding, right?
There is ONE reason to use a mobile phone as a camera, and that is ... its small, and you always have it with you. No matter how good the camera in the phone is, its not as good as a real camera.
Carrying arount that gigantic piece of equipment totally screws up the idea of mobility. And every photograph that wants to make high quality photos with a zoom lens will buy a real camera for that reason anyway.
Its like buying an electric car, and because of its limited range, installing a fuel engine and a tank.
@scayre32
Yep, and a realy amateurish one. Posting 3 minutes apart, posters from the same country, both new members. Spammers arent what they used to be anymore.
great!:good:
Camera problem: red/blue/purple noise in low light photos
Same story from M7 continues with M8. Taking pictures in low light has red/blue/purple noise/tint.
Here is video sample:
HTC ONE M8 Camera Issue- Pink/Red Tint like M7: http://youtu.be/b2sdyGi7-NA
Here's screenshot

You can clearly see on video and picture heat shielding starts degrading, thus parts of the heat transfers to sensor.
Mine M8 produced in May 2014, serial number HT45.
Sensor is Omnivision OV4688 4M.
You can check sensor via file manager, no root is required.
For example, in Solid explorer:
Choose System Root - Sys - android_camera - sensor - open as - Text file - SE TextEditor.
Please report if you anyone has such issue.

Looks good thank you for sharing!
sky effect very well done :good:
Thanks, looks good.
Has anybody else noticed that the screen on the Desire 530 is massively over-sharpened and over-saturated? It bugged me the first time I used it, and reminds me of the over-sharpening on the LG G3.
It almost seems like a filter has been applied to the entire screen. Oddly, the over-sharpening/saturation is turned off whenever the camera is used, or whenever a video is played, and it remains this way until the screen goes to sleep, the over-sharpening/saturation then returns when waking the phone up. The screen looks great without the over-sharpening/saturation IMO, small text is much easier to read because there are no sharpening artefacts and it's generally much easier on my eyes.
Does anybody know how to disable it permanently? It's not a massive deal, as I can always start up the camera to get rid of the ugliness, but I'd like the screen to look natural all the time.
I've tried to capture it in the photos below, the normal screen (over-sharpened/saturated) is on the left, and the more natural screen (after using the camera) is on the right.

not only before camer , in video reproduce its happen, i have same problem htc 530latam
I just changed the color temperature
don't know if that will help you
Hi guys,
I'm not sure if I'm the only one having this problem, but when my phone switches from the main photo sensor to the super macro, there is a clear difference. There is a shift and the colors are not the same.
Here a video to show the problem :/

Same moment, same distance but two photos very different :
the first one is the main camera, and second one is the super macro. The switch is not natural

It's a different camera on the phone isn't it? The switch would be expected. The phone isn't doing everything with just one camera/lens.

Click to expand...
Click to collapse
This is correct. Super macro mode uses the ultra wide camera. Every 'zoom level' in super macro mode just crops image from the ultra wide camera.
The difference would not be too noticeable? Especially in terms of colors and angle!
