Iphone are surprisingly solid with their camera. They can produce wonderful images in optimum conditions.
In sunny conditions they are excellent. The images are sharp and vibrant in color.
Even in low light conditions they can pull off some pretty decent shots. Low light conditions will mean images that are grainy and pixelated in look.
The flash is however rubbish. It shoots a very bright white light with little coverage. I strongly suggest not using the flash in most cases.
I took this at the Iron Maiden concert in St Louis last night. Typical dark concert venue with the stage lights being the only source of light.
With both hands to steady the camera, I was able to take decent pictures. They are grainy as one would expect but colors and contrast are solid.
As for the concert- amazing.
