Paul,
I'm not that tricky.
What I'm eluding to is... Both the "Group photo" and the "Moritz photo" appear to be taken only a short time apart. The "Group" was taken before "Moritz" based on the length of the shadows and if you look closely at MvR and Loewenhardt they are wearing the exact same clothing in both photos. Loewenhardt looks as though he hasn't taken his hands out of his pockets all morning! Also, as Greg points out, 2 different Jasta pilots believe that both were taken 21 Apr.
So lets assume this is true (both taken the same morning but not necessarily 21 Apr)... and as Dan-San claims... the "Moritz" photo was taken in March at Awoingt. Is there anything in the "Group" shot that fingerprints it as being taken at Awoingt? Out-building layout in the background perhaps? Are all the pilots surrounding MvR confirmed to have been at Awoingt at this time... or conversely, anything that would rule it out as being Cappy the morning of 21 Apr?
Wenzl wrote that he took the last two shots of the old master in an "eye-blink" immediately after getting his equipment (camera). Again, If you compare the "Group" and the "Moritz"... the photo of Moritz was taken later ...meaning someone other than Wenzl took the "Group" photo. Could it have been Bodenschatz that took this photo?
I've read Dan-San's POV more than once and he doesn't waiver... sticking to the historical fact (Idflieg gospel) as he always does. I absolutely respect and admire that. On the other hand, Immo's argument is compelling and if you have ever been master of a dog you can read the interaction between MvR and Moritz that completely coincides with Wenzl's story. What we have here gentlemen, is a classic Mexican stand-off... and as long as that's the case, I'll keep passing the ammunition.
VBR
