<p>Hello everyone, thank you all for your very quick responses! I appreciate it a lot! <br>
I used to use a 16GB SanDisk, but then that had an issue back in January. So as a temporary alternative, yes Rodeo, I used a MicroSD card with an SD adapter...<br>
However, now that the 16GB card seems to be working, I clicked around 200 odd pictures, none of them with the coloured areas. So I think it was an issue with the MicroSD card only..<br>
Again, thanks all for your inputs! :D </p>
