Re: New Moderator

As mentioned yesterday, I have taken the action of deleting significant portions of material posted by Mr. Virtuani in January as being inappropriate, offensive, and repetitive. Although these attacks were primarily pointed at myself, similar action would have been taken had any other participant to...

Re: New Moderator

I was unaware of Mr. Virtuani's parallel postings on this thread until very recently. The content and tone of the more recent postings by Mr. Virtuani speaks for itself. He has made his points and stated his positions. Repeatedly. Although I could respond, and have before, I honestly feel it pointle...

Re: A correct attribution for the "Flash Effect" photo?

My own calculations and analysis, done via a method essentially identical to that used by Herr Nilsson, and using identical source material, would suggest that the photographer would be at or near the rail with the mount trained at only about 35 degrees off the centerline. I feel it unlikely that th...

Re: A correct attribution for the "Flash Effect" photo?

My thanks to Northcape for what I consider an excellent response to my question. As they sometimes say 'I couldn't have said it better', but in this case, I'd have to admit that I probably couldn't have said it half as well. I think that even though the outcomes might be trivial in the overall conte...

Re: A correct attribution for the "Flash Effect" photo?

To Wadinga.

One shouldn't offend in public and apologize in private. You are correct; reading your comments carefully, I do find it difficult to take serious offense -or perhaps any offense at all -- regarding the content.

I made a mistake in censuring you.

Re: A correct attribution for the "Flash Effect" photo?

One problem of course is that in reality we have no real idea of how much the photograph has been cropped or enlarged, etc., which renders scaling issues problematical. It's possible from perspective to obtain some idea, but only an approximate idea, of how far the camera was from the gun mounting. ...

Re: A correct attribution for the "Flash Effect" photo?

Mr. Virtuani is cautioned. Although I can sympathize with your feelings that some individuals may be attacking you personally, you will have to trust in my judgement to determine at which point these sorts of comments, which I almost always find unnecessary and unproductive, cross the line into an a...

Re: A correct attribution for the "Flash Effect" photo?

The previous dozen posts have remained fairly reasonable in tone, but I can see that we are beginning to slip back into personal commentary again. I'd once again ask that participants stick to the issues at hand rather than alluding that the motivations of others are in some way driven by deliberate...

Re: A correct attribution for the "Flash Effect" photo?

The main problem(s) here seem to revolve around determining exactly what mount the barrels seen in the upper right hand corner belong to, and at what angle of elevation and train the mount in question might have been in when the photo was exposed. The difficulty, of course, is that there is really v...

Re: A correct attribution for the "Flash Effect" photo?

Hello Byron. I suspect not. "Hassle-dads", as we used to call them, weren't really available until after World War II, and most -- if not all -- were single lens reflex designs of Swedish origin. There were quite a few good twin-lens reflexes available during the war, a good example being the German...

Re: A correct attribution for the "Flash Effect" photo?

To Alexandros: It is nice to see you posting again. Mr. Virtuani should be able to return to the forum on or about 14 January. Provided he can control previous tendencies to post in an aggressive, disrespectful, and offensive manner, he should be able to continue thereafter. While he was certainly n...

Re: A correct attribution for the "Flash Effect" photo?

I have had a chance to do a bit of photogrammetric work on this photo over the last few days. It would appear that if the image does indeed include 10.5 cm barrels in the upper left hand corner, and these are from the mount in question, and the mount is oriented fore and aft, then the photographer w...

First, my wishes for a happy and prosperous New Year's to all. Also, my thanks to the members -- and there were a few -- who have, over the past few weeks and months, taken the time to offer support and constructive commentary regarding my duties as a moderator, both in open postings and in the form...

Re: A correct attribution for the "Flash Effect" photo?

Please do not attribute an endorsement which I did not make. Mr. Bonomi's work is valuable to be sure, and I am not attempting minimize that, but if you zoom in on the section depicting the actual gunfire action itself you will note that my depiction is significantly different than Mr. Bonomi's. Thi...
