Evalglare from a camera



here is my first topic in Discourse.

I am wondering, is it possible to run Evalglare on normal HDR pictures (took from a camera)?

I am getting this error: 1. Failed to find size of the picture. It will be set to 800.

And the picture should be a fisheye format?!

Thank you

and how can I attached a file?. I would like to share it…


Hi @joe88,

You need to edit the header of HDR image manually and ensure the size is part of the header. If the image is not a fish-eye email then you need to do some extra work. See these topics from radiance’s email list:

HDR Photos with evalglare
Evalglare with regular lens
Image formatting for input to evalglare
