Hello, I have a bit of a weird one. I have a 27inch iMac (see sig) running Aperture 3. I recently bought a Fujifilm X100s (awesome camera btw) and took it out for its first spin this weekend. The pics turned out great with the exception of one weird thing. Every single picture had 4-5 bright green pixels right smack in the middle of the frame. I don't mean where it could only be seen when zoomed to 100%; it was visible all the way zoomed out - looked like a pin prick of bright neon green (in a lot of cases right between peoples eyes!). My first thought when I saw it was my iMac had some stuck pixels. However if I moved the image around the dot(s) stayed in the same spot in the image, ruling that out. I opened the photos in both Aperture and then Preview; still the same dots. I then took some more pics and then opened those in Aperture and Preview as well. All the same result, same bright green pixels. At this point i figured the camera was defective so I sent it back to amazon and got the replacement in the mail today. I fired off some test pics thinking for sure it would be better; that was not the case. I am still seeing those green dots. What gives!!! The only other thing I can say is when flipping between pics in aperture, the dots are not visible while the pic is loading, but after a second or two once the pic snaps into focus on my screen (I am assuming you other aperture users know what I mean?) the dots are right there and visible. Has anyone ever encountered this? Scratching my head here.... ---------- I found one article saying this may be a "hot" pixel on the camera. What are the odds I am 0/2 for defective cameras? I've had two canon DSLRs before this, countless point and shoots, etc. Never had something like this. Seems very suspect? ---------- I found one article saying this may be a "hot" pixel on the camera. What are the odds I am 0/2 for defective cameras?
