To get the best shots, one does not “ALWAYS” require the best camera and lens.
Even a point and shoot cameras (P&S) will produce.
Then what’s the limitation?
Normal cameras (P&S, entry level DSLRs with consumer lenses) have some challenges
1. Low light – Early mornings, late evenings, overcast weather and general indoor shots.
2. Sports/Kids/Action shots – which require fast focusing, speed.
So when shooting with normal cameras following techniques will help in producing better images.
1. Go for photography on sunny days with plenty of light.
2. Subject should not be in a shade, avoid taking such shots (non record shots).
3. Avoid shooting distant subjects then cropping heavily.
4. Shoot within the focus range to preserve more details and contrast.
5. Use appropriate filters in situations when required, like landscape photography, reflected surfaces etc.
6. Follow good techniques to approach the subject without disturbing it much, This results less cropping of the image, gets better IQ and captures more detail.
7. Use appropriate lenses for the appropriate photography (most of us don’t do)! A Macro lens for Macros (more details), Wide angles designed for landscapes. Telephotos/super telephotos for birds (cleaner Background), Medium telephoto lenses for portraits (nicer Bokeh) etc
8. Also similar settings in Cameras until getting proficiency (mostly for P&S) Portrait setting for portraits – Avoids unwanted sharpness on faces Landscape setting for landscapes – Good greens and blues etc.
9. And a standard technique: Keep the Sun behind you, so that your subject will be lit properly in the direct sun light.
10. Keep your tripod/monopod handy, to prevent camera shake at longer focal lengths, in low light for longer shutter speeds (ISO performance of most of these cameras are average).
