Is it the perspective on the left that’s bothering you? Would that be better hidden if the soldier in the foreground was on the other side?

I hadn't really got into my stride with this one. Moving the foreground soldier to the left would have helped but he was hiding another problem on the right. The sub image stopped just below the man squatting on the deck and had to be extended. This was easy enough on the left but would have needed a lot of extra sub on the right and I got lost trying to do this.

I’m much intrigued by your perspective grids, but can’t quite see how best to apply them to an image.

These came about before I had managed to find a good head on U Boat and realised I was going to have change the tunnel perspective to match the sub. They are not for applying to an image they are for applying quite specifically to your image. I did what Sketchup is so fast and good at and created a virtual camera to exactly match yours from the vanishing points in your photo. I then quickly modelled the tunnel (it's basically just a square tube) to exactly match the photo. Once this was done I was able to rotate it in true 3D space relative to your camera, keeping the eye height and focal length unchanged, and export the rotations as 2D grids. It looks like a lot of work but it was less than thirty minutes. The grids fit exactly over your image and show how the walls, ceiling, walkways and water surface need to be distorted to correctly achieve the different degrees of rotation needed for the subs I had found. The last of these was indeed used to re-construct the tunnel for the nautilus image.

I did wonder why the man pushing the torpedo on a trolley is so much taller than the guard standing in front of him, but maybe he’s just a tall torpedo-pusher.

Scaling people is something I always find difficult unless there is a good reference. Not being an expert on the size of subs or torpedoes and not knowing true scale of the tunnel left me guessing. And yes he does look too tall. I hadn't spotted that. In fact in the original photo it is a woman! I had to replace the head.

Glad you liked this image though. Once I got into I really enjoyed it.

You’re being too hard on yourself over the Nautilus entry: it’s a perfect fit for the sub, the new railing and deck sets the tone well, and Mason and Douglas very nearly fit. The only thing I’m not sure about is the focal blur in the distance, which I don’t think you’d get with so much of the sub being sharp. And would the water be green if there’s no sky to reflect?

To be honest I treated that as a pure perspective challenge (including the new railing). That I managed very well but, in distorting the walls and ceiling so much, I degraded the image at the end of the tunnel. I blurred it as a 'fudge' to try and hide this. As for the rest you are quite right but by then I was running out of oooomph and let things slip .....

Thanks Steve. It was much harder than it looked at first sight. Sorry to ramble on such length.

Thank you Mariner!

I'm trying to read your image above. Must be the locals getting out while the going is good!? It's a hang of a crowd that you squeezed on the duckie.

Dennis, I don't know where you are from but here in England presently there is a storm of protest against the "invasion" of young, male, non-white, usually economic migrants who pay criminal gangs large amounts of money to be able to jump into a dinghy and, weather permitting, head for our shores. If you google dinghy and migrant you will see many photgraphs of them, packed like sardines in a can. They nearly always set off from northern France, and the Brithish government seems powerless to stop them. My picture presents a tongue-in-cheek solution: torpedo them!

Here is an extreme example, no Photoshop involved:

Wow guys, that's disturbing. 60 plus people on that raft, all male. That's 2 platoons. I've seen the destruction 1 platoon can make under close orders. Your politicians should seriously address the situation. Is it an on going incident? Take care.
