Hi Chris, I think Adobe Photoshop must have messed up with the header files while creating the HDR. I was about to try the methods you sent in your earlier email but seems there is a shorter route by using hdrgen or photosphere to create the HDR file. I am a novice in this area and your help is really appreciated.
Thanks again for all your help.

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... -Chris On 4/23/13 10:31 PM, Avinash Gautam wrote: 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.
