Originally posted by Marc Sabatella Are you saying that set to 10MP, the K10D file sizes are actually smaller for the same subject? That doesn't seem right at all, so I'd say, forget worrying about focus or any other issues and figure out what menu setting is causing the files to be smaller. No way shol a 10MP JPEG file be smaller than a 6MP one unless you've got a very low quality setting on the former.
A 10MP JPG can be smaller than a 6MP JPG under some circumstances. For example, if the 10MP picture has a bunch of blown highlights or a lot of uniform colours, while the 6MP picture has lots of detail and is very busy. But that's about the only time I can see that being the case. However, I think that may be the case here since so much of these pictures are dominated by a white horse.
Originally posted by justinr The saturation, sharpness and contrast are at their default settings and I would agree that they look a little washed out on the monitor but looked quite fine on the LCD (this was the first time I was using it at an event so it was a bit of a shakedown cruise).
That may be true, but the fact is, the picture of the horse just standing there clearly has some blown highlights. I'm not talking about the sky, but the horse itself. Regardless of what the histogram said, the exposure there was wrong and detail was lost. It would be interesting to see what other pictures you've taken with this camera that don't have a white horse in them.
Also, I just noticed your filenames start with an underscore (which implies you have the camera set to AdobeRGB), but the posted pictures load up as sRGB. Was there a colour space conversion involved? Or did you re-assign the colour space intentionally? Or did whatever software you use strip out the colour space information and replace it with its own?
It really sucks that there's no EXIF data, that would answer a lot of questions.
edit: the colour space thing might explain all the blown highlights that weren't blown when looking at the histogram.
