combining HDR RAW images


Recommended Posts

<p>Andrew,</p>

<p>Sony's latest Image Data Converter software application (<a href="http://esupport.sony.com/US/p/swu-download.pl?mdl=NEX6&upd_id=9790&os_group_id=5">http://esupport.sony.com/US/p/swu-download.pl?mdl=NEX6&upd_id=9790&os_group_id=5</a>) does not support HDR creation or combination of files. The closest it comes to producing an HDR-like output file from a single Sony-RAW file is the D-Range Optimizer edit function. Sony goes as far as providing a setting to reference one or more external file editors, such as Photoshop, for editing files beyond its limited abilities.</p>

<p>There is a barely more extensive online guide than the help file created when the package is installed on your computer - http://guide.d-imaging.sony.co.jp/pmb/940_00/4000/us/</p>

<p>Hi,<br>

Thanks for your response...I d/loaded the updated Data Converter, but the only changes relate to movies I think.<br>

I'm still trying to remember just 1% of the possibilities of this camera, and in fact from what I was reading yesterday DRO files can be RAW or Jpeg, but AutoHDR can only be Jpeg.<br>

I'm fairly convinced that I'm not really any further forward, but it is an interesting journey and this is a beautiful little camera.<br>

<p>AutoHDR, within the camera, does create three bracketed exposures (under, normal and over, where under and over can be Menu-chosen to be from -6EV to +6EV in 1EV steps from the camera's normal exposure). The camera then combines the three internal files into one merged HDR jpg file. It writes only TWO jpg files to the card: the merged HDR file, and the normal exposure file, discarding the other internal files.</p>

<p>Yes, DRO in PASM modes will output one Raw file, or one camera-processed jpg file, or a Raw file plus a camera-processed jpg file. DRO also has a simple Auto option, as well as a series of processing levels. The output Raw file is normal camera exposure. You might then compare the appearance of the Raw to the processed jpg in order to either reset levels in-camera and take another image, or take the normal Raw file into your editor software (Sony's with its DRO function plus other features, or another 3rd party file editor package).</p>

<p>I'd pick the Raw+jpg output option and go from there, BUT, also compare it to the internal HDR file just to fully examine both output. I believe you can have both camera Menu options turned ON, and change modes to/from PASM as you make your trial images.</p>
