I am new to photography and enjoying shooting with my Nikon D3200 camera. Once I take a photo, is there any tool by Nikon or a third party which can give me info like F-stop, ISO, Shutter speed, etc? If there is no tool, does Nikon camera support this after the photo is shot?
Your camera saves this information, which we call "metadata" (because it is data about the data captured in the photo itself — one level beyond, or meta), in every file. There are many utilities which can read and display this. I'm not aware of any software designed for photography which doesn't — that'd include Adobe Photoshop and Lightroom, Picassa, and any image viewer. You can also get stand-alone programs which can manipulate this metadata in various ways, including editing or removing it, or giving you different presentations (like, "find all the photographs I took with a certain lens").
But, in fact, almost all modern operating systems have a mechanism for showing this information built in. Just open the folder on your computer and then, when you see the list of files:
In Microsoft Windows: right click on a file, choose
Properties, and then look in the
In Mac OS X, right click — or command-i — and then click the triangle by
More Infoto expand.
In GNOME, as in the Fedora Linux operating system, right click, choose
Properties, and go to the
Again, each of these operating systems — and not to mention Chromium, iOS, or Android — will have more advanced utilities. But you can see the basic information right there without anything extra.
Once you take a photo, you can view Photo Information by clicking the
Play button on the back of your D3200 and clicking the
Arrow either up or down.
More information can be found on page 98 of your manual. Aperture, Shutter speed, ISO, Focal Length, Focus Mode, Flash Mode, White Balance, and much more is all available via this menu.
(I think) Every digital photo has aditional data stored on it besides the image itself. That is called Exif data (Exchangeable image file format).
A Dslr camera can shoot to a raw or jpg image file, and both formats include this data. Smartphones and compact cameras most likely shoot only in jpg, but it includes this information too.
When you manipulate the photo some file formats preserve this data, in some cases this data is replaced and in some other cases all data is lost, but I repeat, after manipulating the image.
You can read this exif data in some image viewer. For example, the viewer I use the most (in windows) is Irfanview http://www.irfanview.com/. In the Menu > Image > Information You can see all this data.
Another good viewer is XnView http://www.xnview.com/en/. You can see the exif data in a tab called ExifTool.
Inside Photoshop > File > File Info.
There are many tools which can provide you this information: Lightroom, xnview, (probably) any graphic editor.
Also any EXIF tool can provide you this info (check exiftool, its free and very good)
P.S. For sure there is Nikon instrument, which can provide you such information, but I am not Nikon shooter :)
