Dear Tiwari ji and Pankaj ji Thanks for nice tips. I have a tripod stand, and will perhaps use it. I find when I set dial to Aperture mode and increase number (smaller size of aperture) the exposure time automatically increases to degree that stand would be necessary. Thanks Pankaj ji for starting this new tutorial which should help many members.
