THE PLACE FOR ALL THINGS BRYCE - GOT A PROBLEM? YOU'VE COME TO THE RIGHT PLACE


Subject: A slightly better but still increadibly bad panorama, hah.

Bah man this is impossible without a tripod.. Ok I give up on the indoor panorama.. It's no possible given my current situation and fankly it's just pissing me off. I decided I couldn't get enough vertical data to do a full hdri image, and I couldn't get multiple exposures so it would have only been ldri anyway.. The final image is like... 15,500 pixels wide.. here's a shrunken version of it.. I tried to take shots down at an angle, but I took them after the initial shots and I had the white balance/zoom at a different setting I think because they wouldn't match up that perfectly.. you can see a lot of the errors. Oh well. It was a learning experience. This is 40 photos blended together. it's 58 megapixels.. but very crappily pieced together =P. Next time it's outdoors, this is too hard..

Here's a cutout from the full sized image.

yes, there are quite a few errors, but if you are going to use it for an HDRI, it'll work, won't it? Don't mind me, I'm not really sure what I'm talking about.

well in order for it to work for hdri, I need more shots of the ceiling and floor. otherwise it will stretch too much in the vertical direction. the ratio needs to be 2:1 for proper non stretched sphere. where the vertical is 1/2 the circumferance and horizontal is the entire circumferance.

@ Ornlu : Sooooo, R U gonna do that ??? It would be nice to have couple "royalty" free full featured HDRI images, opposed to ones you have to buy on the web !!! :)

Ornlu, Do you have a lazy susan(a tray that rotates on bearings along it's center)? if so put the camera centered on that - perhaps with a book or two to raise the camera so you don't get the edge of the "susan" in the shot, perhaps a towel to allow you to align it vertically and put the whole thing on a small table. gently rotate the susan a certain number of degrees (you can pick up a cheap protractor for a couple of bucks somewhere). the hard part will be to not move the camera while actually snapping the shot. - TJ(Mc Guivermouse)

Yeah.. the problem is that I decided next time I do it I'll have to do the first string vertically, as in the camera being sideways. then the top and bottom string horizontally. The lazy susan idea would be good for the first 0 degree string, but then the 45/-45/80/-80/90/-90 degree strings would be near impossible. Thanks for the idea htough, the lazy susan is actually in the picture =)), can you spot it?

I'm probably saying something about 2 steps behind you, Ornlu, but... You can draw a circle larger than your lazy susan on paper, and mark it off in degrees, set your susan on top, put a mark on the susan directly in front of your camera lens, making sure to tape your camera down (or something). Then eyeball the match between the mark on the susan and the degrees of the circle as you turn the susan and make your shots.

Nice panorama, btw, and no ghosts or 2-headed cats, LOL. And can I borrow those speakers?

Yep . . . Mc Guiver would use materials on hand. for the vertical you might use a book or two on one edge of another book to get your angle. the problem here is to secure the camera to the book in some way - thread?. Again a protractor would be handy.

The B&O's stay IN the house, haha... There's also a big ole subwoofer that I built tucked back there. I'll try the lazy susan thing, it might actually work =). The main problem that I encountered was that my angled photos wouldn't match the top edge of my original photos. The angled ones had a more.. zoomed feature than the originals due to paralax or something.. I'll try all this tomorrow once the room gets some good light. it only takes about 10 minutes or so to take the pictures. I'm also going to composite this (actual) hdri image tonight or tomorrow morning. It has 15 levels of exposure, so it should be kind of cool... I should probably post on the photography forum, if there is one, but I like it here, lol.

A slightly better solution would be to get a door hinge and two 1x? lenghts of wood attach the hinge to both pieces of wood and drill a hole where you want the camera to go. get the right size bolt at a hardware store(be very careful in selecting the bolt; you don't want to screw up the tripod attachment threads on your camera) and put the bolt through the hole you drilled on the wood to secure the camera. . . . but you should have a real tripod for this type of stuff. You can pick up a tripod fairly cheaply can't you?


Ornlu ( ) posted Fri, 27 August 2004 at 12:34 AM

Yeah probably.. Again I was just goofing around, so I'll just give it a try free hand, if that doesn't work I'll use the lazy susan approach. If that doesn't work, I'll throw the camera at a brick wall and stop trying.
