Masks are recognised by both Enblend and Enfuse, so if you don't apply your mask to all layers in a stack Enfuse may well produce a set of intermediate images which are difficult to Enblend (and vice versa). Enfuse doesn't really recognise "the properly exposed" layer of a stack the way you and I d

Hello all, I'm having some problems with the Hugin 2011.4 Win32 executable from the current (Mar 2012) sourceforge download. I'm getting the "out of memory" process failure with projects which should be no more demanding than those I had sailing through 2011.2 without problem. Sometimes it's Enfu

May I suggest an experiment ? 1. Take a RAW file and convert it -- so that the whole DR is included -- into a single TIF . ( In order to get the whole DR into the TIF, you will have to flatten the global contrast. ) 2. From this TIF, manually create a +2EV TIF and a -2EV TIF, so you now have a se

Pit, are we talking about the lens distortion and rectilinear projection peculiarities ? I was hoping that Hugin's ( Fulla & Nona ) lens modelling would be sufficient to 'remove' these obstacles prior to / during deconvolution ? :-J On Mar 20, 4:24 pm, Pit Suetterlin wrote: > Erik Krause wrote

Thank you, Thomas, for the pointers. So it's just a GUI problem, not a bug. The uncorrected preview requires explicitly setting EV=0 in two places : first on the Cam/Lens tab ("reset" button) and on the Preview tab ("mean exposure" button). Doing one without the other, or typing "0" into the prev
