Do you guys take pictures in 16X9 or 4X3 and why? I have been using strictly 16X9, but I see that some people say the pictures come out sharper in 4X3. Is that true?
4:3 matches the size of the sensor so you're probably going to get a tad sharper image.
The taking of the pictures is the easy part... all the science going on behind the scenes sometimes makes me miss the old days of film when all you worried about is mixing the chemicals and getting the processing times right.
16x9 is nice for display/viewing. 4x3 imo is better if you plan on printing the picture.
