  HDR compositing (Message 1 to 9 of 9)

Following my question in p.a-u, I searched the web for some free 
software. I came across this site: 
http://www.techsupportalert.com/best-free-high-dynamic-range-hdr-software.htm 
and used the first one proposed (Fusion 1) to try out on a POV scene.

As render set, I used 4 renders of my Urbex scene with varying light 
intensities and processed them through Fusion 1, using the Summator as 
advised on the site. This is the/a result.

I think this looks quite promising while needing further experimentations.

This would be a result using the HDR operator instead of Summation.

I knew something was not right.... the old age painter might have done a
dual-tone paint: one below 1m or so, one above... maybe with a
contrasting line between the two. (dark below, lighter above)

And probably a different color for the ceiling... traditional white ? or
egg-like ?

I am following closely the original photograph where the whole space is 
painted in the same way, walls and ceiling. There is however a wainscot 
along the wall and the stairs. I have not yet provided that. Also, in a 
later stage, I may diverge from the original of course ;-)

I think I like this one better. It is a bit less extreme and I just left 
some of the settings alone. Summation used.

Forgot to add: based on four renders with different illumination 
intensities.

About Fusion F1:
- the help does not work. However, a htm document is provided with the 
program.

- The program also can read png files although this is not mentioned.

It looks like the list has changed a bit because it no longer have HDR software
called Fusion 1. And it starts with Luminance. And there also a good tool
https://aurorahdr.com for creating HDR effect.

Look at the site again - the first entry is still "Fusion" (not "Fusion
1" though).

IIRC, Fusion 1 became Fusion at some point. I have used it recently for 
my own photography; /not/ POV-Ray ;-)
