Is Camera+ photo info true?
Hi,
I have the Camera+ app on my iPhone 3Gs for over a year now.
When you take a picture with this app and open the 'Photo Info' screen for the picture you just shot, there is some more detailed information (e.g. shutter speed, ISO..)
The official site (camerapl.us) states:
"Photo info - it’s in the details
Easily find out detailed info about your photos including when they were shot, dimensions, sizes.
(..)
And for all you photo geeks, we even display the finer details like ISO, focal length, shutter speed, etc. Camera+ puts the power in your hands."
So I was wondering: is the given information true? I mean, the iPhone is just a mobile phone, not an advanced photo-camera. You can't change settings like shutter speed or aperture by yourself, it's all software-based (to my knowledge). Focus and white balance can be changed by 'tapping' an object or color on the touchscreen.
Also: If the information is true, would the displayed settings also be good with an SLR camera with the same ISO?
For example: When an iPhone picture looks correctly exposed at ISO 200, with aperture f/2.8 and shutter speed 1/400, will a picture from a 'real' camera also do so with similar settings?
And of course they won't look exactly the same (according to the lens, the camera itself, etc.), but I'm asking if the exposure would be comparable.

You are referring to the EXIF data header in an image. That information is as accurate as the camera manufacturer makes it. If you use the same ISO, shutter speed, and aperture between any camera, the exposures between all the different cameras should be the same. In reality, there are slight differences, perhaps up to 0.5 stops.
Of course, the sensor size and lens will affect quality, but the exposure will be comparable.
I went from Boston to Miami and back final Oct and had my digital camera and my toddlers had 2 35mil cameras and we had no issues in any respect with the x-rays effecting them i think of its a delusion!
