Every image you click with a digital camera today, comes with bunch of data called the Metadata which contains useful information such as Exif data, the maker of the camera as well as the DPI values and File information. The iPhone is no different. Sometimes, this Metadata can be extremely useful as it helps you recognize the device from which the image was shot from or the important data such as shutter speed or exposure value from the Exif data.
One way of gauging this information from an image is to download it from the image capturing device to your computer and using a software to read the data. However, in this age of mobile, who likes to do something like that. This is where an application called Investigator comes into the picture.
Download: The application is available for free, though app supported with Rs 55 in app purchases for extra features here
When you open the application to look up the data, you are greeted by this super creepy screen of a detective. Before we talk more about the application, we would like to put on record that the whole experience of the app really bugged us thanks to constant barrage of ads top and bottom, in fact, accidentally baiting us to click on them too.
Anyway, once you are in the application, you can click on the photo album icon at the bottom left and pick the image whose Metadata you wish to look at. Once you pick the image you wish to look at the data of, you get absolutely pretty much everything you need about the image. You also have the option to click on the magnifying glass at the bottom right of the image to zoom into the image. Some of these options are:
Exif data is the first option you are presented. It stands for Exchangeable Image File which brings information like the Aperture value, Brightness value, Exposure Time, F Number, Focal Length, ISO etc. This data can be really useful if you have a great shot on your device and would just like to go through the settings to replicate it elsewhere.
Maker’s Name and TiFF:
As long as the image is taken by an iPhone, you will see the Maker’s name to be Apple. This may change depending upon the device image was taken on. TiFF stands for Tagged image File Format which basically stores the raster graphics. It includes data like XResolution and YResolution as well as the Resolution Unit etc.
Other Data like File Creation Data, Size, Name Pixel Size etc:
If you are willing to shell out an extra Rs 55 which is almost $.99, you can get rid of the ads from the apps as well as have an option to clear the Metadata of the image, so that nobody can get a clue about the images you may have taken and keep your little secret.
