HDR photography on Dalvik

HDR photography is basically essential for photographing in sunlight. If you don’t use HDR, either the sun bleaches the sky or the shadows are too dark to see anything.
HDR combines the two to grab the detail from both.

There are a couple of options for Sailfish: HDR Camera and Snap Camera.

Up until, I was using HDR Camera, the one with the multicoloured flower icon. Indeed, when I upgraded to .68 from ,58 using sfos-upgrade, HDR Camera still worked. Sailfish complained it wasn’t fully upgraded to .68 and after a few days I ran it. It’s only apparent change was to break HDR Camera. The latter now complains it’s the wrong version of Android.

Snap Camera. This is a much slicker app though doesn’t allow post-processing like HDR Cam does.
It can be made much faster. HDR generally requires one to take 2-3 shots. HDR Cam waits between each shot to allow slow phones to process the JPG. Snap Cam can eliminate that so it’s 4s vs 10s.
Snap can change the exposure levels – I’m still experimenting with that.
Saturation comes out low for some reason, especially in the reds. There’s no post-processing and so I generally have to fix the shots on my PC (transferring them is a pain).

There’s an interesting question as to whether something happened to Dalvik’s Camera API in .64/68. HDR Camera is a really old app and I’d be surprised if it had a check for Android version v10 r64! .64 slightly updated Android to this security release and also updated Sailfish’s own camera app.

PPS. Nokia 900 and Maemo had the first commercial implementation of HDR where I fell in love with it.


There’s HDR mode in Advanced Camera, for native solution.

Is this flawlessly working for you? On my Phone (Pro1) HDR mode most of the time is crashing Advanced Camera.

Yeah I probably should have mentioned it.

I use Advanced Cam a lot for its (digital) zoom and its ability to set resolutions (particularly widescreen). But the HDR feature has never worked on the XA2.

Ah, Pro1. No, I don’t have one.

I have XA2 and, contrary to issue #56 it does not hang the app on my phone. The effect is quite subtle, but noticeable.

That effect is indeed so tiny I might not have noticed.

I’m using gcam(see screenshot) on my x10III, and it works great. You’ll have to change gallery app from within settings though, because it expects a different app to be present, and then crashes after taking a picture. But now it’s 95% stable.

It also has improved IQ compared to stock camera, especially in darker circumstances.

Suits me, I’m going for more details in shadows and highlights, not “HDR-ish” look. Still would be nice to have some more knobs to wiggle :wink:
