  HDR creation config. Possible values:

-

  weight=triangular\|gaussian\|plateau:response\_curve=from\_file\|linear\|gamma\|log\|robertson:model=robertson\|debevec:curve\_filename=your\_file\_here.m\
   (Default is weight=triangular:response\_curve=linear:model=debevec)

- **-l** **--load** HDR\_FILE
