Taking panorama pictures
Hey guys, would it be better to take panorama pictures without a wide-angle lens on or not? I imagine it would be better to make panorama pictures without a wide-angle lens due to the fact that each image will appear bigger and give a better experience once it's all stiched together. What do you guys think?..

I shoot a lot of panoramas (see site below). I shoot in portrait mode and the focal length is generally determined by where I have to stand and the composition of the pano. I don't like to waste pixels so I generally use as long a focal length as possible. Thus, I loose little when doing the final crop on the pano.Leonhttp://homepage.mac.com/leonwittwer/landscapes.htm..

Difficult question to answer!.

What stitching software will you use? How much RAM do you have on the computer that will do the stitching? What size will you print the final panorama?.

Most stitching software have limits on the size of the composite...at least they seem to slow down and stop. Some of this is undoubtedly due to RAM and HD constraints. But practically, I have never had much success stitching a composite that results in a picture with over 100 MP..

Printing a 100 MP image is expensive. That's about 15000 px X 7000 px. Printed at 300 DPI, that would be 50" X 23"...or printed at 150 DPI (plenty of rez for a pic this big), it would be 100" x 46". A typical price for big panos is from ePingo. They want $283 for a 100" X 46" print or $72 for a 50" X 23" print. If you are printing smaller than that, you don't need 100 MP..

Some stitching software has difficulty with input images that have much geometric distortion (the free AutoStitch is one). If you use one of these programs, I'd avoid WA settings and instead, pick a mid-FL that is better controlled. Otherwise, you will have to process each image with something like PTlens..

I generally orient my camera in portrait. That gives me more vertical in a classic horizontal pano. I use a tripod with a custom pano head. I use full WA, which in my case is 24mm (equiv)..

I have a little Canon A610 and there is a supplied pano program with it. It has a problem when stitching together wide-angle images with the darker corners, which are not a problem otherwise..

The said camera has a panorama shooting mode, so that the display shows a third from the previous image, thus helping to frame of the next overlapping image..

Autostitch is better than the supplied software...

I have a reasonably fast computer so I'm not concerned about my computer lacking the power to stich together pictures. I was hoping to put these pictures up on the web. I don't have any intentions of printing it..

What would you do?..

For panoramas-.

-use tripod. you must keep it level with the horizon. if your tripod does not have a level builtin then buy one that slides into your flash hotshoe. again make a max effort to get the camera level..

-for exposure. set the exposure by pressing halfway and noteing the fstop and shutter speed. you are trying to find the brightest part of you panorama scene to be. once you have found the brightest check the fstop and shutter speed. put camera into manual metering mode and use those settings. do not change them for any part of the panorama..

-lens selection. I shoot mine with a 20mm. tried a 35mm didn't work, the individual shots didn't overlap. the angle of view wasn't wide enough. note: SHOOT THE LENS VERTICALLY. this is the only way to get some vertical scene, otherwise the panorama will be shaped like a hotdog.

In vertical you are cutting your angle of view way down. my tripod has degrees engraved in the mount, I was shooting at only a 15 degree spread and in looking at the shots before stiching there wasn't that much overlap. I later shot panoramas with 35mm 50mm; the hot dog effect was more pronounced. the panorama itself did work..

-determine in advance the center point of the scene and try to go X number of shots on each side of it. for me with my setup a 120 degree scene is 7 shots; the center and 3 on each side. if I go with a 35mm lens then a 120degree scene will take 13 shots. no matter what lens you use realize that you are adding only 33% new scene with every shot, the rest is overlap for the right and left adjoining shots. the only exceptions are the end shots in the whole scene. it is possible to add another row above and/or below the first one.



- I stick my hand in front of the lens and shoot, then shoot the panorama, the 7 shots, then put hand in front of lens and shoot. later I know that everything between hands is the panorama..

I have used cs2 or the panorama factory software to make the panorama. for either couldn't be simpler simply select the shots and it does the work. this is where using a level pays off. the software is leveling the scene to make the long rectangcal, but if the scene was not as level as possible in the first place the vertical becomes less and less(you end up with hotdog shape). so having the tripod and camera level is very important. also when mount and shooting vertically make sure the camera really is vertical, carefully check by looking threw the viewfinder.



-on focusing-.

What I do is to simply preset the 20mm lems at infinity, because of depth of field everything from 5.64ft to infinity is in focus at f11.0 distance 200ft..

You can also use a hyperfocal focus setup. but thanks to the DOF table, just setting the lens at infinity is simpler..

I left WB alone, that is set at AWB; or you can use a preset setting like sunny or cloudy, but once set donot change it till panorama shots are doneonline depth of field calculator available here-http://www.dofmaster.com/dofjs.html.

For panoramas, the software I use is either panorama factory orPTGui or cs2. the one that works best for me is PTGui..

The below panorama is 5976x2816pixels, or prints at about 16x36, is a tiff of 95.9mb. it is the view from my mother's front porch. it currently hanging on her front room wall. it is a 120degree view and is made from 7shots..

A panorama viewed on the web is TINY. My screen is rather big (1680 x 1050 pixels) If I take a 360 degree panorama, it will be about 18000 X 4000 or 72 MP. It will not fit on my screen. I might reduce the pixel dimension by 4X, yielding 4500 X 1000 or 4.5 MP. This will fit vertically, but I'll have to scroll horizontally to see the entire pano..

This points out that you don't need many pixels for this application..

I have two Dell 2007WFP which have the same resolution as your LCD. I still don't want to shoot at low res because I want to have the ability to print it in the future should I try it...

I suggest that you ALWAYS record pix at the max resolution of your camera...silly not to, IMO. The discussion was, I thought, whether to take pix at full WA or to zoom in a bit. You stated that by taking more pix at a mid-tele setting, the resultant composite would have more resolution. I stated, and gave examples, showing why you don't need more resolution. Good stitching software is NOT hindered by WA pix with vignetting and barrel distortion...they fix it..

By all means try different ways of taking panos...I did..

A assortment of notes:.

To fight vignetting (dark corners) try to stop down from your lens' widest aperture and increase overlap..

Select a fixed WB, Auto can produce variations in some scenes..

I've been successful with PTGui. It will produce larger panoramas than some photo editors can deal well with. In fact, editing, not stitching, puts the limit on workable image size. And then, how do you view it?.

There is software available to provide zoom capabilities for panorama viewing. some may require viewers to download and install application software..

For short wide panoramas there is a video option available. I have used the free software wpanorama at http://www.wpanorama.com.

There are lots of resources available. Here are some examples:Max Lyons Forums:http://www.tawbaware.com/forum2/panoguide:http://www.panoguide.com.

And of course, visit my site. I provide some info pages (Viewing panos on the web is difficult enough that I found it necessary to provide these explanations on my site. They are not limited to just printing considerations.)Panoramas on SMUGMUG. Issues about panoramas such as those on this sitehttp://dbdimages.smugmug.com/gallery/1920784Cropped Panoramic Prints.http://dbdimages.smugmug.com/gallery/1904456Panorama Printing Resourceshttp://dbdimages.smugmug.com/gallery/1904509.

Take a look at others panorama display approaches and see what you might try for the pictures that appeal to you. Mine are on my site..

Good Luck!.

There is no general rule for focal length.Each situation requires a different approach.Have a look at my panorama tutorial page for some examples:http://www.millhouse.nl/digitalpanorama.html.
