[Radiance-general] HDR Photos with evalglare

[Jan Wienold]

Hi Nassif,

the most important thing is, that you KNOW what is your type of lens you 
are using. Then you have to "transfer" its specification into correct 
radiance view parameters.
what you need is view type, horizontal and vertical size of the image.

If you look at the documentation of evalglare you can see, that you can 
specify the view type when calling evalglare (you don't have to add the 
view spec to the HDR file):

/In case, the view settings within the image are missing or are not 
valid (e.g. after the use of pcompos or pcomb), the view options can be 
set by command line options. As soon as view options are set within the 
command line, view options within the image are ignored. The view 
options are implemented according to the RADIANCE definition (please 
read man page of rpict for details)://
//-vtt Set view type to t. (for fish-eye views, please use --vta or 
--vth preferably)//
//-vf viewfile Get view parameters from file.//
//-vv val Set the view vertical size to val.//
//-vh val Set the view horizontal size to val.//
/
And be sure using the latest version of evalglare (1.11).

Good luck!
