Hi Avinash,
Just a followup: I was able to install and run evalglare on the .hdr
created from last night's .nef files (Method 1). I then performed the
following two operations:
pfilt -1 -x /4 -y /4 test01.hdr>test01s.hdr
evalglare -c test01g.hdr test01s.hdr
Everything seemed to work (i.e., I got a grayscale output image with a
green 'glare' mask). I suspect that since the header information (I was
calling it 'metadata' before) was already in the image, there was no
need to add -vtv, or declare -vv -vh. Here is what I found in my
test01s.hdr header:
#?RADIANCE
CAMERA= NIKON D90 version dcraw v9.12
hdrgen created HDR image from '_DSC3776.tif' '_DSC3775.tif'
'_DSC3774.tif' '_DSC3773.tif' '_DSC3772.tif'
EXPOSURE=3.280407e+00
VIEW= -vtv -vh 37.200130 -vv 25.245402
CAPDATE= 2013:04:23 23:46:20
PRIMARIES= 0.6400 0.3300 0.3000 0.6000 0.1500 0.0600 0.3127 0.3290
FORMAT=32-bit_rle_rgbe
pfilt -1 -x /4 -y /4
I hope this helps...

I am trying to generate a hdri image from my camera Nikon D90 using
various lenses. My Nikon camera generates a .NEF file in RAW version
however I was able to generate a .HDR file using .JPG of the same
images in Photoshop. After I generated the .HDR file I tried running
evalglare on it which gives me an error. I understand I need to have a
fish eye lens to get the full view in order to get the correct results
but the purpose of my experiment is to test the error in dgp using
different lenses that are not fish eye lens. I am using the --vth
command and have entered the --vv and --vh as calculated for the 35mm
lens on a DX format camera (25.74degrees and 37.4degrees). This gives
me an error */pict_update_view: unknown view type /*and */error:
invalid view specified/*. Can anyone please let me know where I am
going wrong.
Thanks,
Avinash
