Morgan Pugh,
at 1st I though that it may be uneven flash lighting
due to the 1st 3 pictures but that does not explain the last outdoor
picture. So I looked trough over 300 pictures that I took with my A95
for the same effect but nearly all were taken outdoors @ a ski resort
where I set the camera to overexpose by +1 to +1-1/3 EV in order to
get correct exposure of the skiers. Yes this blows out the sky & much
of the details in the snow but that was unimportant, the skiers were
my subjects & they were properly exposed.
Also your editing software removed the EXIF metadata from all
4 pictures so there is no way to know the camera's settings which
makes it much harder to respond to your question or to try to recreate
the conditions with my camera to see it there is any sign the same
effect.
In 2 of my 300+ picture I did notice a very slight light
intensity drop off in the extreme upper left corner of the pictures,
but it is very, very slight & probably would never have been noticed
had I not been looking specifically for it.
My guess it that you most likely have a defective A95,
probably the CCD sensor is not in the exact center of the lens. This
would explain the light drop off in both corners if the CCD sensor was
shifted up just a little too far. This is all just my opinion based
on what I see & know about digital cameras, there could be other
reasons but this seems most likely. After all, the manufacturers are
not going to make the lens any larger than they need to in order to
minimize costs, so I suspect sensor placement is critical.
Exchange it & test the new 1 as soon as it arrives. The A95
may be the last such P&S camera in the Canon Axx camera line with CF &
4 "AA" batteries because Canon seems to be converting their entire P&S
line over to SD memory. With that said, it's still a great little
camera & I for 1 like the CF & 4 "AA" batteries since I have a
considerable investment in CF cards that I use with several digital
cameras including my DSLR.
If you can repost the pictures with the EXIF metadata intact,
that might help.
Best of luck.
Respectfully, DHB
