As new Gigapan Epic Pro panoramic head upgraded with the Arca Swiss clamp.
Purchased new only a few months ago from 360TacticalVR.com and used to produce a dozen panoramas. I need the money to fund the manufacture of my own panoramic head so it has to go.
£700 ovno. Posted (UK only) or pickup from Gloucester or Anglesey. Paypal acceptable
best regards
Kev Lewis

doesn't the ptviewer java applet handle spherical panos? it isn't very versatile but that will run on pretty much anything

Took delivery of the Samyang 8mm f3.5 fisheye from 360Tactical (thanks Andrew) so this weekend was spent shooting star trails
and my first pano with the lens on a Canon 7D
www.photosbykev.com/wordpress/photography/landsca...
Always have trouble with the nadir image so please forgive that minor problem.
Very very impressed with the lens/body combination just need to control the flare on the lens

Can you post a small version online for us to look at? The distortion maybe a function of the stitching which could be corrected. The forum experts should be able to help with that as I'm primarly a photographer and I really am a newb when it comes to panoramic work. Photobox are a very good print house I get a lot of my work printed there.

ignore the custom pixel ratio. Just goto Image size, uncheck constrain Proportions, change the resolution if needed; for printing I would suggest you use a minimum of 150 pixels/inch, preferably use 300ppi. Then in the Document size change the units to inches and enter the print size you want. At the bottom select Bicubic smoother as you are enlarging the image. Then hit ok.
View the image at 50% magnification and apply the smart sharpen filter I use it set at 100%, 0.2, 0 and apply it a number of times until the image looks just too sharp at 50% then undo one or two steps of sharpening.

It would be worth learning how to read the histogram function in the live view of the 450D. Using the histogram will quickly tell you whether you can use one exposure to cover the dynamic range of all the scene or if you need to consider using multiple exposures. This is good tutorial on the histogram and how to read it www.luminous-landscape.com/tutorials/understandin...

I've tried a few software packages and ended up buying PTGui as it delivers the results I want and is very versatile.
Re exposures, alway set your iso setting to a manual one rather than auto. I tend to shoot at iso100 most of time and accept the longer shutter times that will be needed when stopped down to say f16, using iso 100 gives me the highest quality with minimal noise. The only time I would change this is when subject movement becomes an issue.
Ensure your white balance isn't on auto, I use the cloudy setting on my 40D as I like the general appearance of the images straight from the camera, I then batch adjust the colour temperature of the Raw files before exporting them as Tif files for processing in PTGui.
Finally always shoot in manual exposure mode rather than auto or Tv or Av or god forbid program mode This will ensure that you have a constant exposure to work with.
If you need to change the exposure to prevent the sky burning out then either use Grad ND filters for the sky shots (and remove the filter for the lower ground shots) or consider doing multiple exposures at each position and then HDR/fuse them together before or during stitching.
With the 8mm lens the filter option is out of the question so multiple exposures and HDR is the way to go.

The aspect ratio of the print is defined by your 18" x 3.75" image file so to print it at 8" height the length would need to be increased to 38.4" (i.e 18" x 8"/3.75") if you wished to retain the aspect ratio. You could change the aspect ratio in Photoshop or similar by unlinking the the height/width and just resize the height but this would result in a vertically stretched image which may, or may not, look odd.
An alternative would be to create a blank image file that was 20" x 8" and copy into it your image plus another image of similar proportions and print two images together which would at least save paper. I've recently done this with three 36" wide panoramas which I had printed on a 36" x 24" sheet and then separated them for framing (much cheaper than 3 separate prints) as shown below (if it displays anything)

Thank you Hans I will have to lower my sights with regard to size I think and just offer a smaller pano. No problem with the seam that is the result of quickly editing the levels and curve in PS on the 'low' resolution file I can correct that.

Thank you for the feedback John,
the file is very big, if I compress it any more artifact start to show up and the full screen view becomes ugly. I will take a look at the HDView viewer for the bigger files.
I assume the control response is down to the power of the viewers computer once the file loads. I wonder if there are parameters in FPP that can help with that issue, I will take a look

Thanks for the response Valentin,
the file is 5Mb and the image size is 7400x2400 pixels so it will take a time to load

A view from the side of the straits showing the new and old bridges.
tinyurl.com/56td87
I've shot this using a 40D and a 28mm lens in portrait mode and 4 rows of 3 bracketed exposures giving me a total of over 200x60Mb tiff files. I've quickly processed the files using medium resolution jpg files and put it on-line. The question I'm asking myself is do I process the Tiff files
The reason for shooting with a 28mm and portrait is to get the detail in the final images rather than a quick 4 + 1 pano.

first attempt at anything other than simple stitching www.photosbykev.com/wordpress/index.php/temp/ but interesting to do
I dropped every other exposure and ran one set through photomatrix when I was happy with the tone mapping I saved the settings and then applied those settings to the four main image sets. The 4 tonemapped files were then put through PTGui, some minor stitching errors in the roof planking but easily sorted with some more care. 16bit Tif exported to CS3 for processing and saved out as a 1Mb jpg (sRGB)
For some reason I can't view any of the links that are .mov files I have QT loaded but they just don't show in the browser.
