Not sure if this should be in here or in Problems…
I have attached a WIP of an apartment we are working on. I have recently started rendering out EXR images which allow me to re-expose in 32bit space in Photoshop. However, this shot isn’t working as expected.
Now obviously, I haven’t got the balance of lighting right yet, but I thought: “Hey, I should be able to open this up in Pshop and re-expose so that the ceiling halogen lights look less blown out, cool!”. However, when I do this, it doesn’t expose as expected - if I under expose, it looks like I am using plain old levels on the image and all the blown out bits just fade to grey. I would have expected the blown out bits to remain as bright, but just shrink in size (if you know what I mean) so that I can bring more detail out of the paintings on the wall.
To get unclamped output to an .exr file in RC3, you need to use either of these methods:
1) render to a .vrimg file and then convert to .exr with vrimg2exr;
2) use the the “split render channels” option of the V-Ray VFB;
3) use the “save image” button in the V-Ray VFB;
If you just use an .exr file output in the Common tab of the Render Scene dialog, you will get a clamped .exr image. This is corrected for RC4.
