How do I adjust the camera's resolution?

"To change the resolution for different environmental settings,

Select the button to the right of the screen with a camera icon labeled: scene.A menu should appear onscreen, select the second option in the center labeled: scene mode.Choosing one of the options listed will change the resolution and camera settings for specific environments.

I hope this answers your question!"

I had the same problem , I found that if went to the camera settings and scrolled down to the reset all button selected that and then the megapixel size options were selectable again. Hope it works.

I am doing this and the megapixels are not changing.
