My Samsung Galaxy Ace S5830- Photo Quality

To compare the difference in the quality of photos taken by Samsung Galaxy Ace, I've snapped the below photos. Those products are placed in a cabinet, with the presence of fluorescent light from the surrounding.

Photo A: Auto focus ON, flash OFF

Photo B: Auto focus ON, flash ON

The quality of the photo seems to be better without flash, with the condition of sufficient lighting from the surrounding environment.

ps:All photos above captured by my Samsung Galaxy Ace GT-S5830. (Original size and quality, without any modification/photoshop)
