1.What setting is best used for shooting kids in low light condition at outdoor ? I tried the following setting but the result is bad.
• relatively high shutter speed (1/100s) with flash. The object is well exposed but not the background.
• Slower shutter speed (1/2s) to properly expose the background but got blur object since my kids is moving.
2.What is the significant of the max f number (minimum aperture) of a lense. For example, a lense with f/2 – f/4 and f/2 – f/5 ?
