i think no need to mention those sentences again la.. ya ya the thing behind the camera matter most.. haha.. we all heard that..
but its good to tweak the camera photo style that suits ur needs, as it saves u a lot of time editing it later... for my 450D i normally hv the contrast higher and tone also higher... something that looks more "nikon" ..haha.. i shld had just bought a nikon in 1st place
As in picture styles is the feature which allows you to set image processing parameters like sharpness, contrast, saturation etc. to determine how the JPG will look like.
also, it allows you to shoot B&W photos in camera if you select the monochrome picture style.
I like to set my sharpening high on my picture style because i find canon's default sharpening is not enough. If you like your photos to look good out of camera, you might also want to pump saturation a bit. It's up to your personal choice. The differences are slight, but noticeable if you compare up close.
