equivalent), 1/250 second, f/4.1 (wide open for 140 mm) |
|
|
|

greatest telephoto (140 mm equivalent), 1/1000 second, f/4.1 (wide open
for 140 mm) |
|
|
|
Canon A620 at iso 100: intermediate focal length (72 mm
equivalent) and distance, 1/200 second, f/7.1 |
|
|
|
Same as photo above, but cropped
|
|
Canon A620 at iso 200 on a tripod: Full frame (no crop). Macro
central spot auto-focus
at longest focal length
(140 mm --equivalent) with central focus
point over
the nose of Hamilton on a $10 bill. Tungsten illumination
(color corrected in Photoshop
with
"Auto-Color"). No sharpening done, 1/50 second, f/5.
|
|
Macro auto-focus on $20 with flash at f/5, aperture
priority,
focal length 7.3 mm (shortest).
Note the
over
exposed
image when used with the built-in A620 flash at short
distances in the macro mode. |
|
Macro auto-focus on $20 with flash and FlashClip
(http://www.flashclip.net/)
flash diffuser
at f/5,
aperture priority, focal length 7.3 mm (shortest).
Note the even exposure because the light is
diffused and angled. |
|
|
|
|
Seven shot panorama (9438 X 2759 pixels, 74.5 MB) in portrait mode at 71 mm focal length
(35 mm equivalent).
iso 50, 1/250 second, f/4.5
.
The panorama was assembled with Canon's free PowerStitch software.
No post-processing done.
The resolution of a panorama is much higher than a single shot photo from
a wide-angle lens and has less
distortion because a longer focal length
was used. |
