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

Hello to Mr. Wadinga: here a better picture of same mount. Chains and 'solid' railings are clear. They are the forward 105mm mount on upper 'boat' deck. Same for the center 105mm (on weather deck). There are other positions. PE Railings.png The photographer may have been in more than one position (i...

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

Hello, to Mr.Wadinga writing: 'Hans has helpfully drawn two variants' : sorry, what you mean for variants, please ? My drawing is trying to position the centres of the muzzles ends but the green lines (axis of ellipse) are not well visible: the right muzzle is seen bigger than the left muzzle, due t...

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

Hello, to Mr. Wadinga who wrote: "to me simply drawing a line through the end of the gun muzzles intersects Bismarck amidships. This is essentially a flat 2D world": the optical effect may be this, but there is no way to calculate where this line ends, it depends from Bismarck distance. Simply drawi...

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

Hello, to Mr. Wadinga who said: "Hans, could you explain why you say : 2.No, or just only very roughly. Since drawing a perspective line through the centre of the ellipses you have used would surely intersect Bismarck amidships ": we can calculate with trigonometrie the angle from the muzzle end pla...

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

Hello, the angle posted by Mr.Jurens may be related to the distant right muzzle, the close left muzzle appear to be seen from a 10-15° ahead of the plan through muzzle. My calculation, based on trigonometry, assumes the ellipse minor axis is linked to the sin(angle) not to the tan(angle). If tan(ang...

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

Hello, About Mr. Wadinga questions: 1.Yes, due to their shape. 2.No, or just only very roughly. (Two different plans for the two muzzles appear to be present, due to perspective effect from photographer POV: the left and right gun bores are seen from very different angles. For this reason I agree th...

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

Hello, the "flash" photo interprtations from Mr. Nilsson, Mr. Jurens and Mr. Virtuani seem all realistic possibilities to me. Thanks for your excellent drawings and explanations. Mr. Wadinga: you say 'an extended plane through the muzzles intersects the Bismarck'. This is just an optical effect, the...

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

Hello, history is always written by winners and Mr.Jurens is right: this don't preclude it can be in some cases written accurately. When there are however controversial aspects, I have never seen losers version of history to become the accepted one. In these cases, always winners impose their point ...

Re: Presentation

Good afternoon, I have recently registered for this forum, but I have not yet manasged to post my first message. I have become passionate for DKM Bismarck after I have built a 1/350 model of the ship and since then I have read several books on the story of this wonderful ship. I have found most inte...

Re: How did you come to be interested in Bismarck?

hi,

im new to this interesting forum.
my interest for Bismarck comes from a beautiful 1/350 model of DKM Bismarck that my uncle has built some time ago.
since then, i have read "Schlachtschiff Bismarck" from V.Baron von Mhullenhaime-Rechberg.

I hope to learn a lot here.
