Raw shooting with C5 ultra Dual E5533

[francoistoen]

Hi

Using FreeDcamera it is now possible and easy to shoot in raw mode and save dng files. Look at xda search fro FreeDcam thread made by defcomg.:smileysmileythumbsup:

Well working (but read all the thread as the app working is a special made on the link being on post #57)

Pictures can be edited by Lightroom, Photoshop rawtherapee and others. 

All the best

Hello Everybody...

... following the previous comment on this very thread I've been able to shot some indoor and outdoor photos in RAW, converted them in DNG and then in Standard DNG that photoshop opened without complaining.

The verdict is: GENUINELY RAW - No sign at all of jpeg artifacts/noise, the picture is clear however there are some catches for who is not used to shot raw photos:

Indoor photos without flash will produce photos with a lot of grain, as there is NO POST-PROCESSING in place. If you don't want it to happen, change the ISO to 100 or lower (my E5506 apparently cannot shot at less than 100) and use a flash. - Notice that indoor, ISO 100, FreeDcam will slow down a lot the refresh rate of the picture on screen. Not sure if it's a bug or not.

Color reproduction may be not accurate, in the case of my C5 (E5506) there is too much yellow but it can be easily retouched.

For who is not used to RAW/DNG pictures: are big files. Shooting RAW to then converting in JPG with compression is worthelss. If you have lot of space in your computer, save pictures in TIF.

Here a 1:1 detail of a photo showing 100% of details:

To recap: I wish the author of FreeDCam the best in developing this app, it has really LOT of potential to become a popular camera app for Xperia users as seems that Sony is not going to allow Xperia's cameras to use Camera2 APIs.

Thumbs up!

My E5553 can't go below ISO 100 too, 

I tried capturing a photo at ISO100 during night time (approx 8.00 PM), apparently the shutter took few seconds to complete and light trails can be seen. The slow down seems to happen only at poorly lit or night conditions, does freedcam automatically adjusts the shutterspeed /exposure in conjunction with the ISO values?

hi im the main dev from freedcam. e5553 does not support full manual mode as it looks. only isopriority what i have seen.

in low light conditions, the ae triggers the nightmode. that means is use lower shutter speed to avoid noise.

that part is not direct controled by freedcam. it comes from the native camera side.

you can indirect control it with moving the exposure slider to negative values.

that tells the ae to use faster shutter speed and higher iso. when increasing it ae use slower shutter. 

about the color calibration in dngs: we are using the nexus6 matrixes for most devices because it match best.

to have true calibrated colors we need a pic from a "Colorcheckerpassport".

Whitebalance itself is not a problem, it can get changed due postprocessing.

about sony not adding camera2 support. thats not 100% true sony z5 use camera 2 and it is ported to z1-3. but that are qcom based socs. for mtk based socs i did not yet see camera2

Hey troopii it's nice to see you here. If camera2 API is not present in the mtk soc how do you manage to get raw data? Just curious

[troopii]

Its a hacky way.

On mtk socs is a engineer mode. Its added for testing the device functions.

with activating it you can dump a raw(16bit plain) from the hal. that gets then saved to sd.

that raw gets then put in an dng container from freedcam.

i think rawcapture is theoretical possible since android has camera support.

(defcomg was able to dump raws on good old o3d)

but it gets disabled from manfacturs after drivers are written and camera is calibrated.

about the time where the z1 and g2 came out qcom added the ability to output bayer-raws.

on z1-z3 sony disabled the raw stream. but freexperia working on it and on roms based on it, have it already working.

Wow, Good Job! Kudos for you, and let's hope that Sony won't spoil such great job!!!

Hi troopii

I tested your last revision this morning (3.3.131) and all is broken (black screen).

I reinstall the last revision (3.3.130) special design made by defcomg and linked to a post in xda forum.

http://forum.xda-developers.com/android/apps-games/camera-freedcam-4-0-3-t3115548/page6 on post #57

and things are good now.

You mentionned the mtk engineering mode in your post, do you know a way to enter that mode with the last mediatek mt6752?

Thanks for your job
