      That's the one! :o)

     Just checked: max_trace_level 5

     No, I didn't do a recursion level. Stumped now with this new term...

     This is what I did do though...

   //CODE

  global_settings {
  assumed_gamma 1
  max_trace_level 5
  #if (Photons)
    photons {
      spacing .03
      gather 20, 100
      jitter 1.0
      adc_bailout 1/255
      autostop 100
      radius 100
      // (---Adaptive Search Radius---)
      //steps 1
      expand_thresholds 0.2, 40
    }#end}

  And, LOL! In my interior statement, I DID forget to lower my 
dispersion_samples from playing around before!

    I had it set at 140 for this image.... <sigh, whistles almost

   Thank you Tim.

    Heh, that did cross my mind as I had loads of DT icons! (Now cleaned 
up).  :o)
