Fake miniature 360 of Oxford

I stumbled upon a tutorial on "fake tilt shift" photography and thought I'd have a go applying it to a 360.
I've been staring at this and fiddling about with it for so long, I'm not sure how effective it is, but it was quite fun to do.

Nice, I like the fake tilt shft idea. I'm currently working on a combined 12 scene combined miniature panorama myself. I'll show it when it's ready (can take a while  )

Thanks for sharing.
I'm really attracted by this work and, after reading the blog and tutorials about 'Fake Tilt Shift', I tried to 'produce' something similar.
I wonder if the 'original' was an equirectangular or not; 'cause in my case (working with an equi) I finally had a quite visible seem after the 'treatment'.
Any hint?

Never edit the edges of an Equi, only if you can do it exactly symmetrical. You could shift the entire image and then edit the part you want.

Thanks for the positive comments chaps.
Klaus - yep, the original was an equirectangular and I also ended up with a small seam - I extracted the relevant part of the pano with PTEditor and got rid of it.
On the tilt-shift theme, there is a cool short video that is currently doing the rounds and is worth taking a look at.

@Henri ("Never edit edges of an equi ...")
Well, Henri, I do know that.
But also noticed that the lens-blur filter, which -I suppose- was used by Jez, affects the edges, too.
Therefore my question
@Jez
Thanks for opening your "making-of" notebook a bit.
Will try again ....

Using this tutorial for a spherical panorama will not work.
You will not just get the issues at the 360 degree wrap but you also get some funny stars at zenith and nadir.
The way to do this on an equirectangular is to extract large zenith and nadirs using panotools plugin, Ptgui, or may be the new patch tool in Pano2VR.
I used Panotools and made this, just a small 4000x2000 pixels version.
www.panoramas.dk/technics/fake-tilt-shift.html
Just extract a very large FOV nadir/zenith, I used 160 degrees.
Use a circular feathered selection and apply your blur.
Convert back to equirectangular (insert) and paste this one as a layer into your original. delete the black part. There will now be no issues with the edges.
You can now apply some opacity if you like which will create the dreamlike effect I did on my test.

This is a variation on the effect:
The shot was taken on a fairly bright summer day on Dartmoor but I wanted a winter shot to portray the atmosphere of the place (remember the Hound of the Baskervilles?)
www.j-a-willetts-esq.com/dartmoor.html
So, working with different layers and using the eraser to keep the landscape's perspective, I used the blur technique together with a dirty grey to transparent fill.
Finally, I reduced the overall colour saturation.
But note, there is no rule that says you must show the Nadir and Zenith in every panorama. You decide on how much the viewer can see - it's your creation - and it can save a lot on work which only the purists will admire - and theyt don't pay the bills

Ahh this brings back memories!
As a keen hiker, Dartmoor has been a regular stomping ground of mine over the years.
Seeing this pano reminded me of my time visiting these particular woods and I swore I heard the "Hounds" howling!
I enjoy seeing the patched nadir and zeniths to give you that feeling of being surrounded by the environment but equally hear, hear on leaving them out if it saves time.

Ah, you've discovered the truth.
After hiking across Dartmoor with panoramic gear, I was shattered - and forgot to take the zenith and nadir safety shots.
Much easier to take Cathedrals but not nearly as much fun
