THE TEST­ING PA­RAM­E­TERS

Consumer Voice - - Comparative Product Test -

Video Qual­ity

Video qual­ity test­ing was done to give over­all rat­ing for the cam­era’s video qual­ity in dif­fer­ent light con­di­tions. The ex­pert team tested var­i­ous videos for sharp­ness, smooth­ness of mov­ing sub­ject and colour ac­cu­racy.

Im­age Sta­bi­liza­tion

It means how well the cam­era com­pen­sates for trem­bling mo­tions and images that might oth­er­wise be blurry. All the cam­eras were ex­am­ined for im­age sta­bi­liza­tion as they were ex­pected to ab­sorb the move­ments and sta­bi­lize the im­age and store the same.

Pic­ture Qual­ity

This is the most im­por­tant pa­ram­e­ter as ev­ery con­sumer wants the pic­ture qual­ity to be sat­is­fac­tory – clear and sharp. Over­all rat­ings were done by as­sess­ing pic­ture qual­ity in dif­fer­ent light con­di­tions and at dif­fer­ent zoom ranges.

Flash Qual­ity

When op­er­ated un­der the de­sired con­di­tions, the flash has to be syn­chro­nized with the ‘click’ but­ton to ad­e­quately il­lu­mi­nate the sub­ject in fo­cus. Also, the en­ergy has to be im­me­di­ately re­stored for the next so that con­tin­u­ous pic­tures can be taken. Apart from th­ese nec­es­sary func­tions, flash qual­ity was ex­am­ined for its abil­ity to ad­just to bright­ness, light strength and ap­pro­pri­ate dis­tri­bu­tion of light, among other things.

Auto Fo­cus

Even pro­fes­sional pho­tog­ra­phers tend to keep their cam­eras on auto fo­cus. As long as you un­der­stand how it works by rec­og­niz­ing the area(s) of fo­cus within the cam­era's viewfinder, auto fo­cus is usu­ally bet­ter than man­ual – an im­por­tant func­tion of the cam­era to be judged for rat­ings. The ap­pro­pri­ate­ness and in­tel­li­gence lev­els of ‘aut­o­fo­cus’ were thor­oughly ob­served.

Viewfinder

The viewfinder has always been effective for tak­ing pic­tures, be­cause press­ing the cam­era against the eye ac­tu­ally stead­ies it. It also helps the pho­tog­ra­pher frame the pic­ture. In ad­di­tion, bright sun­light can wash out an LCD, mak­ing it dif­fi­cult to see the sub­ject. The viewfinder’s abil­ity, ease of use, po­si­tion and clar­ity were among sev­eral el­e­ments ad­judged for rat­ings.
