I would like to expand this with non-SFOS phones, at least I will do so with this post.
(If this is not welcome, I can delete and repost as a thread on it’s own. I also know, there is a “box” function for fotos; if anybody gives a hint, I will edit)
The intent is to give an impression, how other camera apps handle exposure, white balance, contrast, micro-contrast, sharpening, etc. Also in order to give @Jolla some inspiration, how to further develop their own camera app.
So I have taken a longish walk last Sunday, with the purpose of getting an idea, how different the phones at hand compare to each other. They were all put to 4:3, max resolution, standard mode; the only manipulation of the exposure was tapping at the lighter area, in order to “expose to the right” - if possible. The FP6 and X23 allow this, the JP2 did not react noticeably.
No post processing, I did reduce the resolution, though, as the files ware crazy big with no noteworthy detail.
The following devices were used:
FP6 - e/OS - Fairphone camera app v8.00.01.0011.2.0
JP2 - SFOS - advanced camera app 0.9.8-1.4.1.bso
Volla X23 - Ubuntu Touch (24.04-1.3) - stock camera app 4.1.1
Handling and feel:
FP6: is the fastest of the bunch. It just snaps into focus, on touching the trigger it takes the foto instantly.
JP2: Pretty good contender. Slight delay, but very capable in quickly grabbing a scene.
X23: A little slow in finding focus, but the delay from pressing the trigger to actually taking the foto takes ages (+/- 0.8 sec.) If you are around kids or animals, you will miss a lot of candid shots. I guess, this is mostly due to the weak CPU of the device.
About exposure & colours:
The FP6 tends to overexpose (even if you nudge it to ETTR) and adds a yellow-green hue.
The JP2 tends to balance out big contrasts and rather would give up some highlights, in order to save some low lights. It quickly goes down to 1/30 exposure time even in bright scenes, so camera shake is a big issue. It adds a blueish-green hue.
The X23 shots come closest to what I “saw” (or actually, what I wanted to see later in the foto)
About lens, bokeh, etc… Just have a look
