<p>Thomas: Could you render a 3000 sample Version and compare some pixel-values by hand? I still believe the result should be identical (unless the renderer already shoots more photons in noisier areas - don't know it that's already supported (but you probably do).</p>

<div>well the way to test would be to do the 3600 sample render
and compare the results. you can do a convert to grayscale then
Boolean subtract the two images, then invert the result to see
pixel differences.</div>

</div>
<div>I suspect the 3600 sample image will be superior. should be
identical render time but require no post processing.</div>

<div>now I want to see the image in question, too! care to post

<div> Yes, that's what Jordan suggested. :)<br>
This makes sense and also gives better results.<br>
<br>
I hope we will get a better solution though, a good merging
system would be awesome. :) <br>

<div>> have you tried merging them
weighted ("factor" setting) proportionally to the
number of samples?<br>

If the second image was in the second input, shouldn't
you set the Factor to 0.66? :)<br>
