Pano copy cam |
|
|
After seeing the incredible panoramas people have stitched together, I was
thinking of doing this the make high resolution copies of my artwork. The
problem is keeping the camera at the same distance and the sensor plane
parallel to the painting/drawing surface itself. Obviously, swiveling the
tripod head won't work. Some type of linear adjustment mechanism would be
needed.
Any thoughts?
Thanks, John

I have yet to do something like this...but I know what might work. Make a
stand....a box made of metal or plastic. On the north upright side arrange a
way to hang artwork flat to the plane. East and west are open for
lights...you might want to look into polarizing these. On the south wall
make a pipe that goes horizontally with clamps on the end and a clamp in the
middle for a tripod mount. By moving the clamps around you can put the
camera anywhere you want on that plane.
Or...make a wooden grid...put a tripod clamp in each one...move camera from
clamp to clamp. Be sure your photos overlap by quite a bit...25% on each
side is not too much.

Might need to put some markers around the outside to help align the images.
But with care...should work fine. I have only done one pano using PS-CS but
it did fine. It really should be easier than the OP expects.

Ryadia's method will work fine - I do large building panos this way all the
time. If you don't have wheels handy, draw a line that is parallel with the
artwork and hang a plumb-bob from the tripod. Match it to your line, when you
move the tripod. You might also find it easy to mount the artwork in wooden
rails on the wall, and move it, in front of a static camera.

If it's a painting or drawing etc, why not move that instead of the camera
?. If it's on a flat suface ie floor them the distances etc will stay the
same.

i do a bit of this kind of work. Doing Panos of sy a painting is different
than doing panos of land scapes. My personal out of the box answer for you is
a HP Scanjet 4600 ($79.00) or the HP Scanjet 4670 ($179.00). they are not your
average flatbed scanner. you can moce the scanning surface across your image.
I use the software that comes with the scanner to stitch them together. the
best part is that there is no more worrying about horizontal and vertical
planes!
Hope that helps! |

You can take either approach. Either you rotate the camera around the
entry pupil of the lens, or use plan-parallel shifts of the artwork or
the camera. With the latter (shifts) approach the postprocessing is
much simplified (assuming a distortion free lens), but even rotating
can be compensated for with software (at potentially a slight loss of
resolution).

Or move the artwork in front of a camera on sturdy tripod.
