You could tell because low resolution makes for a pixelated picture, and high resolution settings, you cannot tell.
[no. horizontal pixels] * [no. of vertical pixels]
The image resolution of a picture is broken into pixels. The amount of pixels in the picture depends on the size of the print. There are approximately 100 pixels per inch in a picture.
Digital uses mega pixels ... vs film resolution is based on the area u have to record the image
The measure of clarity of an image appearing larger is typically referred to as resolution. Resolution is the level of detail that can be seen in an image, often expressed in terms of pixels or dots per inch (DPI). A higher resolution generally means a clearer and sharper image.
with your image resolution? Nothing happens it remains the same till you change it in Image Size dialog. Image > Image Size.. Magnification is for your convenience to see enlarged image nothing really happens to actual resolution of original image.
Go to Image > Image Size. If you want to keep current Width and Height of the image uncheck Resample image then type new reolution in Resolution field. When you want to resample image (to change Width and Height to match new resolution) check Resample Image and type desired resolution in Resolution field.
Resolution of image is used to determine the quality of image in digital camera.
Changing the image resolution will affect the file size of the image and the quality of the image. Image resolution is measure in DPI, which is Dots Per Inch, this means that if you increase the resolution then the DPI will increase and the quality of the image will get better as a result as there are more pixels that make up the image, so the image will be more distinct and sharper. When the image resolution is increased the image has more pixels, this is the exact opposite to the compression techniques, this means that the file will get a lot bigger as the number of pixels increases. Decreasing the resolution, however, will make the image quality lower but will reduce the file size.
Right click the image, choose properties and go to the summary tab. You will find there the image width and height. Together they give the image resolution.

Resolution is defined as the smallest number of discernible detail in an image. Spatial resolution is the smallest discernible detail in an image and gray level resolution refers to the smallest discernible change is gray level.
Image Size
Image > Image Size
After opening the image you want to check the resolution of by going to "File", then "Open", click "Image", and then from the dropdown box, select "Image Size". In the new box that opens up, the width, and height boxes will tell you what resolution the image is.
When you change physical size of image in Width and Height fields its not necessary to change resolution. If you publish image to web you are inerested in Width and Height of image not in resolution, if you gonna print image then you must look in Resolution, most printers need 300 pixels per inch to print. Changing Resolution field will automaticaly change Width and Height of image in Photoshop (turn on Resample Image) and you will get best possible result with pixels you have.
