Thank you MM Anderson, Cathy Lindsey and Mel Steinhauer :)
I spent a lot of hours playing with manual mode shooting macros of Tulips on the kitchen table using different lenses and found that changing the f stop and exposure time really made a difference in the DOF and image quality. So with that I was able to use that info to increase the quality of pics taken elsewhere. Can't wait to get out and try some more ideas. Taking the tripod next time. :)
