Support Uncompressed RAW

[tommiehansen]

When using the app RAW's shot with it comes out as compressed RAW even though uncompressed RAW is choosen within the firmware. One can clearly see this by just checking the file size:

First is compressed (shot via the focus bracket app), second file was shot after exiting the app.

Do any of the Sony apps save uncompressed RAWs?

[tommiehansen]

Yes, ie:

[α7 II, RX1R II] Shooting and saving in uncompressed RAW is now supported.
[α7R II, α7S II] Silent Shooting and Shooting and saving in uncompressed RAW are now supported.

I have no idea why the apps just doesn't respect the user setting(s) though. One would think that if the user sets A the value A should be what's used.

[obs1dium]

Interesting. One would have to look into how that app does it..

[tommiehansen]

A problem could be that uncompressed RAW isn't supported in burst modes?
In any continous mode(s) the cameras that does support uncompressed RAW usually goes back to the 11+7 bit RAW's (compressed/lossy RAW's).

Checking the code i see this:
m_camera.burstableTakePicture();

#176 @ https://github.com/obs1dium/FocusBracket/blob/master/app/src/main/java/com/obsidium/focusbracket/FocusActivity.java

Or is the 'burstableTakePicture()' a custom function?

[obs1dium]

That's just (as far as I can tell) the way one takes pictures with the framework. The app explicitly sets the drive mode to single shooting.
What about the Smart Remote app? Does that save uncompressed RAWs as well?

[tommiehansen]

The smart remote uses another system i think. The last time i checked i think i saw something about takePicture() or similar. Isn't there a list with available functions anywhere?

The other refence from the PMCA demo overrides shutter down action:

@Override
    protected boolean onShutterKeyDown() {
        camera.getNormalCamera().takePicture(null, null, null);
        return true;
    }

What would be the difference between burstableTakePicture() and takePicture() ? Does the former return a current index that in a simpler manor can then be used to check it against an array or...?

[obs1dium]

takePicture() is part of the Android SDK, whereas burstableTakePicture() is part of Sony's API. Smart Remote uses the latter IIRC.
You could try both Smart Remote and PMCADemo and check if they produce uncompressed RAWs. I can't test that myself.

[tommiehansen]

Could not get the PMCADemo to take any pictures at all. Sony smartremote just saved JPG's and i've forget where one fixes that (i never use that app). Tried your 'BetterManual' app, some thing there.

[obs1dium]

The BetterManual app uses a third method that Sony calls 'direct shutter' - I couldn't get burst modes to work otherwise.
You should be able to enable RAW shooting in the Smart Remote app by pressing the camera's menu button once you're connected to it.

[tommiehansen]

Can't test now since I'm abroad, but if takePicture() is part of Android shouldn't that function also have higher compatibility with more settings etc? The current app has some problems with some lenses and I'm basically thinking that those could be solved.

Anything 'burst' in the current fw for the A7x series basically forces the camera into certain modes and that might be what is happening?
