Roy, you might try the Canon panorama utility, PhotoStitch, that comes with all Canon digital cameras.
Load images, then in the tab "Merge", select "Merge Settings", then set to Image scanned in sections.
This will often work with images of differing focal lengths, croppings or scale, and if necessary you can also assign multiple control points.
Regards,
Ed

Andrew
Just enter "wireless strobe trigger" in Ebay to see the product, that sells under many names and prices.
Mine shows TR-06 but is the same as PT-04 and appears similar to the Cactus.
The receiver unit really likes fresh (full voltage) batteries, and they seem to last. However I've gotten 23A batteries in stores that have been around awhile and are close to dead.
It comes with a PC to 1/8" cable. (I really dislike PC connectors but didn't take the time to replace - yet.)
The wireless strobe trigger & modified Nikon IR remote.
and mounted on a D40x:
Here's a mod to extend the transmitter range.

The importance of this mod to me was more in achieving a solid signal at around 30+ feet rather than distance.
A similar item is the wireless camera trigger. The Canon would probably be easier to adapt using a mini-plug rather than the proprietary Nikon connector.

Ed

Gus said...."If you've used a wireless remote like these (tinyurl.com/6ndl75) at ebay, you will never use a wired or Infra-red remote again."
I just plugged my 4-channel strobe trigger receiver into the (above described) modified IR-remote on a D40x.
Then hand-held the radio transmitter, originally designed to place on the camera. and now it wirelessly triggers the camera via the IR remote perfectly.
Thanks for the thought Gus!
Regards,
Ed

My take on it - hope it's not too redundant:
For a printer think DPI. Many Epsons use 1440 or 2880 depending on speed needed and paper surface used. The glossier the paper and more complex gradients (16-bit) the higher the resolution needed to avoid banding.
For a source file, think PPI, a minimum for matte paper (with "normal" viewing distance) is probably around 140 PPI, and for glossy at least >200 PPI, and for half-tone on coated book or magazine stock, >300 PPI.
For a camera think PPD (pixels per degree FOV.) The wider the lens, the fewer PPD (less resolution per degree.) At some size source file (under 3000h x 6000h?) the benefit of longer lenses and more exposures is minimal.
Here's a calculator:

Yes I've followed your Merlin work for awhile now with great interest...and a few questions.
Have you made some panos with the Merlin?
What does the nadir shot look like?
Is it light enough to go on a pole?
I've been staring at simple R/C servos and an old electric screwdriver, thinking of a simple, light semi-automated setup.

Ed

Interesting and innovative image!! Looks like it's really a 1080, and you had the tripod nailed down for over a month. Good job.
One critical thought is that the radically different lighting (color, shadow detail, etc.) is distracting, though perhaps unvoidable.
Regards
Ed

Aloha Juann,
Couldn't decide between Dramimine or Buspar.
Nice pano! Congratulations.

Terrific image Tabb - I live less than 5 minutes from where you took it, and the trade winds can be formidable - as must be your flying skill and lack of risk aversion.

Hi Ken,
In the past couple years for experimenting I've reliably gotten a number of 28mm-xxmm adapters through Ebay from China, usually under $5.00 USD.

Good job with a wonderful perspective...
I do wonder about the insecure feeling one might have by hanging the camera gear at the end of a telescoping pole out over some abyss (as in castle image.) Perhaps you might use a tether, or even the wires for the remote serve that purpose?

Ed

Doug -
Besides ACR, another inexpensive option for CA control is Picture Window:
dl-c.com/content/view/13/27/
It's straight forward to just look in the corners (100%) and adjust the sliders (R-C, B-Y) for minimum CA.
