Re: Challenge 547: The Marseille Mirror
Interesting subject. My take was to recreate the scene using Lego and a mirror above it. However after much time lining the mirror up in roughly the same position as the photo I found the truck was not positioned to get a reflection in the mirror so I repositioned the mirror on more of an angle so there was a reflection. Great job everyone, now I think I'll try a hand at the monkfish.

Thanks DavidMac. I ran out of time on this one.

Re: Challenge 547: The Marseille Mirror
This was an extraordinarily difficult Challenge, so many congratulations to all who attempted it. Some of you came very close.

One mistake several of you made was with the reflections of the supporting poles, and this is a pity because that's really the key to the whole image.

Look at the angle of the poles as they relate to the buildings. You can see that rather than sloping inwards, they're actually precisely vertical, their slope matching the angle of the buildings behind them (1).

This means that since the mirror is parallel to the ground, the poles must be perpendicular to the mirror; which means the poles should translate directly through the mirror, as if the pole and its reflection were one continuous length (2).



Realising how the poles reflections work would have made the whole business very much more straightforward.

First to attempt the impossible was GKB, with an ingenious 3D modelled version of the car. That gave him the opportunity to present a true reflection, in which the roof is much more visible. A well judged reflection of that bright white pavement; but a shame about the poles (see above).

An extremely capable entry from DavidMac, with well judged reflections of the surrounding buildings, and a particularly neatly rebuilt van showing us its roof. Again, it's the poles reflections that produce the slight awkwardness, not least because it affects the reflections of the coaches and buildings as well. Thanks for the diagram, though, which explains your thinking very well.

An entertaining vortex entry from Jota120, which perhaps sums up his state of mind when faced with this Challenge... I think that's how a lot of you felt, Trevor.

A fine entry from James, who has not only reproduced the reflection of all the buildings, but animated the van at the same time. Good work! But a pity that, while you got the rear poles to reflect correctly, the front ones showed the same error as the previous entries.

First to deduce the pole reflection correctly was srawland, so much kudos on getting that right! I was also hugely amused by the fact that you chose to merge both this week's Challenges, including finding another monkfish image that matched mine perfectly. You've really excelled yourself with this image! I also very much enjoyed the monkfish stole in the second entry - hope it's properly dried first. I like the ouroboros version!

A psychedelic entry from Ant Snell, whose mirror seems to be buckling down towards the ground. It's a novel approach - and chopping the poles off does certainly get around the problem of what to do with their reflections.

Clever work from Mariner, who has correctly interpreted the poles (nice job) and also made up for the shortfalls in my photography by replacing my background and attendant people with his own view of Marseilles. A very clever solution! And the reflection of the van is very close: it's only the slope of the roof that stands out.

A lowered roof from Garfield72, which entails a huge extra expanse of pavement in the foreground of the reflection. It's a valiant attempt - but you are having trouble with those poles!

A clever approach from Darren, who has rebuilt the scene in Lego and then photographed its reflection. Changing the angle of the mirror will, of course, change the angle of its reflection - but a nice try, nonetheless. And what a grisly scene in your second entry!

So here's the real thing, and thank you all for your patience and especially for the huge effort you have put into solving this week's problem.




And for those who oped for this week's secondary Challenge...

A startling, powerful image from Vibeke, with a real sense of terror on that monkfish's face. I really like the reflection of the shark on the fish's back.

A nice Terry Pratchett tribute from Josephine Harvatt, featuring a blood-spattered blowfish text, illustrated by the monkfish. There must be a better way to embed that animated version, though! Ask James how he does it.

A part-cooked monkfish from tooquilos, simmering away in its pan. Um... I think you're probably supposed to cut the head off first... I like the animated version, particularly the whole monkfish skeleton at the end. How on earth did you manage to create this? I also greatly enjoyed your take on DavidMac's explanation!

I've seen michael sinclair go off-topic more often than not before, but this really is a first. Is that how the subject makes you feel?

Re: Challenge 547: The Marseille Mirror
Thanks Steve. Yes, that one was close to impossible (unless you live near Marseilles).

Re: Challenge 547: The Marseille Mirror
Thanks Steve. I did wonder about how the poles were reflected; it never occurred to me to compare them with the verticals of the buildings. The wide-angle distortion confused me - that's my story and I'm sticking to it!

Probably the most difficult Challenge you've set so well done everyone who had a bash at it.

... still don't fancy monkfish for my dinner!

My hat off to all who attempted this. I looked at quite a few images on the internet, and then decided to practice making skin instead.

Re: Challenge 547: The Marseille Mirror
Thank you, Steve, for your very generous critique. This was by far the most difficult Challenge of all the ones I attempted so far. I spent three days on it, tearing my hair out because I couldn't get the reflection right. I really did feel like the animated person in Anna's response to David's explanation.

I purchased the book in the summer of 2013 and spent 6 months lurking in the forum. I remember thinking: "I'll never be able to produce images like the other members!" I'm still not on par with most of the members here, but I am improving.

Oh, and to get the ouroboros version I had to use two fish.

OMG! I am so embarrassed. I cannot believe that I got this so wrong.

Assumption over observation is so easy but I am mortified to find myself a victim. I am, professionally, supposed to to know far better. Thank you Steve for bringing me down to earth with a bang!!

So many lessons to be learned .....

I knew I had the mirror edge horizons wrong, that was conscious decision, but I cannot believe that I got this so absolutely wrong.

Thank you Steve. I found the skeleton of a Monkfish on Google images. You can actually buy them too! Got a birthday coming up soon lol
