"a seamless workflow and total control and convenience" producing HDR's is too good to be true !?
Soon I will see/not see it
What did I see ?
First thing I saw was that the HDR option on the VRdrive is not needed ! I can use the bracket options on my E-M5, 5 images at -2,-1-0,1,2 EV and the head will shoot it AND produce a XML-file accordingly. So I shot a sphere with the Oly 12mm (24mm eq) with 5 bracketed images, 30x5 images.
Next thing was to import it to APG alpha2 using the VRdrive2 plugin. I've always developed the ORF-files (Oly RAW) to TIF, but this time I wanted to try the direct route. I chose the ORF-files and checked for "I want 32-bits HDR Radience" out !
The files were found and was nicely stacked. I did nothing but push the detection-button. The detected result was OK with a violet tint in the preview. I did nothing but push the render-button. After a while I had a 873MB EXR-file.
What did I get ?
I opened the EXR in Photomatix and I was ashtonished ! No violet tint, no artifacts, nothing, just a nice result
What has happened ? If you shoot a bracketed pano and in some way or another make a Papywizard-format XML (e.g. let VRdrive2 do it) and import it into APG 3.0 using the VRdrive2 plugin, you can have a fused or EXR pano almost auto !
(Don't forget NPP and all the other pitfalls shooting panos)
