In the new years eve I was showing off my new Jolla by taking pictures and guess what when I returned home . The pictures were having

  1. Poor resolution ( a bit surprising )
  2. Red eyes come with flash. ( In 2014 ? )
  3. Auto focus works only if you take a second pic in the dark.
  4. Lot of blurring ( which is understandable for low light )

I might be doing it the wrong way taking pictures, but is there a red eye removal tool via some application ? I dont mind doing some post processing on a GNU/Linux Desktop.

+1 to everything you said. And lots of noise too - I cringe when I look at these grainy images on my computer monitor. Why can't Jolla make me look like an amazing photographer? :(

@pavi, have you tried Cameraplus app from OpenRepos? https://openrepos.net/content/msameer/cameraplus-0 It has a few more settings than basic Camera, but doesn't change the fact that Jolla takes poor images in dark conditions.

Unfortunately most of the problems with the camera grow out of it's poor hardware. There are multiple threads discussing it, this https://together.jolla.com/question/70966/jolla-device-upgrade-request-suggestion/ for example.

@sifartech grainy images are kind of expected when we do low light photography and when our sensor hasn't such high ISO processing capabilities. I was surprised to see that zoom is just useless , it makes the pics even more worse.

@MikaN Yes I tried Camera Plus its good but I kind of like the main camera UI for some strange reason :D

Answer to your second part: You can use GIMP to do red eye removal. Newer versions of GIMP have a plugin for it as Filters, Enhance, Red Eye Removal. If you want to do it by hand there is a tutorial for it at http://www.gimp.org/tutorials/Red_Eye_Removal/

Thanks I used the plugin in gimp but it was not that efficient. First thing is we need to manually zoom in and select the eyes. As I mentioned above the grainyness implies the resolution is really bad. So I zoomed in and wow drawing circles on eyeball which actually look like pixel blocks was painful. But the good news is it worked for 2 images and it didn't for the third. I tried adjusting the treshold but my friends eyes when removed of the red had green devil eyes :D ( so I had to undo it )
