PanoTools NG:
Blending question when shooting outdoors - 20D Sigma, Fisheye, PTgui
Rick Drew 2007-Mar-05 21:58:21
I'm using PTgui and just started getting serious with my 20D and Sigma
Fisheye (Was using a Nikon and screw on Nikon Fisheye adapter - decent
results, but too soft.)
The 20d and Sigma produces cropped fisheyes, not full frame. I'm shooting
four images, all high contrast (ski areas, so it's bright white, dark woods,
deep blue sky, etc.) If I went automatic, the 20d tries to shoot at 1/8000 -
it's bright! The blending is pretty obvious - when looking at the full equi
image, there are four visible brighter oval areas - it looks pretty
amateurish. Plus the sky has a Frisbee on it when looking straight up. I
never had this with the full frame fisheye images. When shooting the
images, I shoot like I always do:
Manual
F stop as high as possible
Exposure time averaged between high and low readings
Shoot the each image bracketed, 1 stop up and down.
HDR the images
Create the pano with PTgui, output to a layered PSD file
Perform surgery to remove extra arms, legs and heads
Remove the tripod
Any suggestions or ideas?
Thanks
Rick Drew
