Anyway, time to duck my head again. 1 of the disgruntled unions are striking in Durban again today. Must have some new demands on May's millions she pledged for improvements in beautiful S.A.

Considering the Mary River current and the amount of silt and debris, the photographer got a great photo for this weeks challenge...

Loyd, you really are very good at this video stuff aren't you?

Great images all. Sorry I haven't been able to participate recently, and such interesting start images too. Hopefully I an manage one soon. I miss them!

Re: Challenge 701: The Mary River Turtle
First to treat the turtle this week was GKB, with a comical joke beak. I think you should take that bottle of pink hair colour back to the chemist, Gordon, it’s a bit patchy. I like the tank in the second entry - but surely even an empty glass tank would produce some refraction? Ah - now I’ve seen the animated version I see it’s actually full of water. So even more distortion required! I like the fish, though, and of course the Django.

Clever work from Josephine Harvatt, grafting the turtle onto Churchill’s body. A very fine treatment, the head fitting perfectly in there - and that hair makes remarkably good grass.

DavidMac sees the turtle as Beaker from the Muppets - and yes, there is a strong similarity. Especially with those new eyes. Nicely done.

I greatly enjoyed lwc's entry. A really splendid animation, with a real underwater feel, made possible both through the overall pulsing distortion and through the subtlety of the waving hair and rising bubbles. Love the moving eye too. Masterful, Loyd. And a very fine second entry - but I wonder, would it be possible to avoid the jump when it restarts? Here’s a quick fix - I’ve added the final frame onto the final two frames of yours, at 30% and 70% opacity:



Ingenious work from Mariner, who has taken the turtle’s hair off (and grafted on a new top of the head and body) and placed the whole thing beneath a grass-covered shell. I really like the general clean-up of the turtle, too - that looks very much more appealing.

A great musical image from dwindt, with a punk turtle playing that well known punk instrument, the banjo. A terrific open mouth, and a fine choice of dazzle background. Very strong altogether.

The turtle neatly inserted into a remarkable creature scene by srawland - what an extraordinary scene it is. All Star Wars extras? Nice work on the X-Wing in the animated version: is that just three different angles? Very convincing. I’d like to see more turtles in there, though.

A fright wig from tooquilos - and I really like how you’ve adjusted the eye to make the turtle more Trumpish. A great opening title and studio in the animated version - but that’s what I’d expect from someone working in the industry. I like the zoom in on the map - good to see where this river really is! Most entertaining.

Truly extraordinary work from Jota120, with a whole turtle’s head grafted onto some poor drinker and the condition spreading to his neighbour. Nicely done, Trevor, but that’s quite a medical condition!

Re: Challenge 701: The Mary River Turtle
Thanks Steve. Techy stuff alert.

It might seem as if there should be more refraction through both the water and the tank but light is actually coming through a planar surface at a right angle (what is called ‘normal’) so there would be no refraction. If the light was coming through at an angle or the surface was curved as in say a goldfish bowl shape then refraction would occur.

When I set up the refractive indices I used 1.5 for the glass and 1.2 for the water and Cinema calculated no refraction because of the light path.

If you imagine a diagram of the light path through a convex lens you see that the incident ray ‘normal’ to the centre of the lens passes unrefracted while the rays that are not ‘normal’ are refracted and come together at the focus.

I’ll get my coat

I've tried all kinds of transitions to fix the hated "abrupt jump". Your fix is excellent and far better than anything I've come up with. I've taken it a bit further using 20, 40, 60 and 80% in the last four frames. I also changed the frame rate of the last five frames from 6/100 sec. to 10/100 in this example. This was the runner-up to the one I posted. It also helps a little by keeping the original 75 frames instead of culling to only 50 frames.

Re: Challenge 701: The Mary River Turtle
Thanks a lot Steve.
An interesting challenge, tried, practiced another approach and technique. Will persist as gives some interesting results and a challenge.
Interesting also for me it was based off an older photo I dug out which taken sometime ago. (The future manipulates history. Stop)

(Aside: With further manipulation and genomics - DNA. Maybe such hybridizeation is not so far off, or it could happen anyway as you maybe imply with virus or convergent evolution..... enough!!.... The answer is maybe within the answer 42)

Re: Challenge 701: The Mary River Turtle
Thank you Steve. Originally, I had thought to put the turtle in a scene from Burton's "Alice in Wonderland" or perhaps his "Through the Looking Glass" However, I couldn't find a good scene. And, then there would have been animating it. Then I decided to see if I could put him in as a Star Wars alien. I Googled "Star Wars Alien" and came up with this cast of extras image. I couldn't think of how to animate the turtle in space so I left him out.

Re: Challenge 701: The Mary River Turtle
That’s very interesting. And may well be true. But somehow you expect to see some sort of distortion - perhaps a diffusing of the image? A slight murkiness? Or maybe some slight shifting around the edges of the tank. Often what we expect to see isn’t what we actually see, and surely we have to exploit the expectation rather than the reality?

Re: Challenge 701: The Mary River Turtle
It’s an interesting problem. Yours is very close, but it’s really hard to fool the eye to a big enough degree. How did you make those bubbles? Did you have to position them for each frame by hand, or were they cleverly animated?

Bubbles are an animation. Particles could be any number of things other than bubbles. They can be manipulated for direction, size, volume, speed, etc. I used it three times in this weeks challenge, one for each nostril of the turtle and one for the diver.

Having to do each frame by hand would never get done by me...

Thank you Anna!

I was very fortunate to find a photo of the same turtle taken from the opposite side... that alone made the animation possible.
