Swiss Panoramic Images + Urban Lines

Roger

Anyway, I tried with ipad. Lot of noise but some success.
A pure blender sculpt in my home, with some help of additional lighting (I admit it). But environment requirectangular panoramic worked. (some stretching still there, and lot of noise

So, you are aware of Paul Debevic's work with light probes? I see from your sculpt that you want your pano to serve as both light source and background image. I think I would use the pano as light source and do a small HRI image Photoshopped behind the head. In regard to my panos, had I continued shooting around the nodal point in all directions, the result would have been an equirectangular 1x2 after it had been stitched. You can set up your camera and a gigapan system to do HDRIs and the pano at the same time. The robot will bracket exposures at each camera position befor advancing to the next position.

This is what I am aiming to achieve.

You see in my urban panoramas, some of them are completely 360 degrees but I couldn't post-stitch them into an equirectangular format. They can still serve perfectly for backgrounds but they do not render accurately. Of course you can replace the background but that's not the point.

Very nice panoramas, but I need equirectangular 1x2 panoramas. The worse is I need interiors. The worst is that I need hdris and mostly empty places.
I need them badly. Good luck to me.

Well give me a week or two! I'm going shopping this weekend!

Roger I will PM you an in-depth reply. Thank you for your wisdom.

About equirectangular panoramas. I did some search and the only I can understand is that: basically there are two 180º wide square photos, stitched together. A 1x2 format.
Am I right?

No, There are 6 photos taken every 60 degrees, then one photo up, and one to two photos down (nadir).

Look at the first few images of this tutorial, it shows how tripod is set up with resultant images.

You need 8-9 portrait wide angle photos.

Buy the cheapest camera with a fisheye lenses.
But it has to be capable to work manually.

I need a good quality dslr as I will be using it for other applications too, not just panos. Looking at nikon d5100 or d90, can't decide. The D90 seems to be a more professional oriented camera, I don't care much for better video quality on the d5100. d5100 does not have auto focus built-in either.

It's either this

Must modern DSLRs will have a set up for automatic bracketing. You set it for a under exposure, correct exposure and over exposure. You press the shutter once and it will make all three exposures.

Despite of the name it's in English!

And go to the technical part

Have fun!

PS And of course don't miss the flying over the Eiffel tower!

roger i have sent you a loooooong PM

Pilou, you legend Great resource, looks like michalis can use his iPad after all.

You've got me reading all night now!! Time for another coffee.

Why don't you model a room and render a nice panorama of it? Then you could perfectly control the output. Most of the times (with shots like yours) the background is a bit blurry due to the DOF anyway.

Roger

Gai, the way I read it is that Michal wants to capture views of existing rooms and spaces as setting for his interesting sculptures. I think he would rather not model the room and with teh complexity of his forms he would rather not have the additional weight of the setting. Additionally the photo would provide the scenes lighting.

michaliszissiou

Indeed
@Roger @Gaieus
Thank you for your concern.

To model a room. My room for instance.
I can, but, render times will increase rapidly.
I'm laaaaaazzzzy.
The idea behind this is related to a new development of blender sculpting mode.
It's very important to sculpt having a preview of a place, as a background.
Sculpting is not just about construction. It's more about shapes that try to capture lighting. I mean, a flow of shapes, connected, coming from the surrounded place into the smaller details of sculpting. It's the final question about Scale. As we can imitate it in the 3d world. As possible it is, after all.
There isn't anything like an outline around a sculpt. Or around a building if I may say so. An idea, an obsession, when you have it, you can't communicate with your feelings otherwise.
So, we have blender sculpting now, with the ability to render (cycles) under a physically correct GI fast renderer. A GI renderer tends to "eat" carving, casted shadows, as hell.
This is so close to what is happening in real sculpting... I'm impressed.

Sorry for spoiling OLI's thread, but it may demonstrates why it's so important to have such surrounding environments. An easy access on such environments.

This looks like a 3d render. !!!

Please allow me a post, to show how hdri equirectangular panorama can help me.
Not my panorama though... A free download.

Just you wait michalis I'm gonna build a huge library.

I have ordered my camera, lens and nodal tripod.

In the end I actually went for the Nikon D7000. Much superior to the two I was previously considering.

I've been taking photos all night!! What a camera and what a lens!! Just wow!

michaliszissiou

Just a question oli.
this lens is a fisheye ~10mm, But on a dx camera this means ~15mm right?
Welcome to the nikon club.
My favorite nikon lens is the 50mm f 1.4 , Classic.

olishea

It can be used for both dx and the full frame cameras.

~15mm?? I honestly don't know!

The fisheye is simply fantastic!! Really impressed with all the kit.

I also have the 18-105mm lens and also a Sigma macro lens which is from my old analogue Nikon.
