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.
The optimal resolution for a 16x20 image is 2400x3000 pixels.
To determine the resolution of an image, you need to look at the number of pixels it contains. Resolution is typically expressed as the width and height of the image in pixels, such as 1920x1080. The higher the number of pixels, the higher the resolution and the clearer the image will appear.
The resolution of an image can be determined by looking at the number of pixels per inch (PPI) or dots per inch (DPI) in the image. The higher the PPI or DPI, the higher the resolution of the image. This can usually be found in the image file's properties or by using image editing software to check the image dimensions and resolution settings.
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.
To determine if an image is high resolution, check the image file's dimensions and resolution settings. High resolution images typically have larger dimensions (e.g. 3000 x 2000 pixels) and a higher resolution setting (e.g. 300 dpi). You can also use image editing software to view the image properties and check the resolution details.
To determine the image resolution, you can check the image file properties or use an image editing software to view the dimensions in pixels. The resolution is typically expressed as width x height in pixels, such as 1920x1080 for a Full HD 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.
The maximum resolution of a 2MP image is 1920 x 1080 pixels.
The resolution of a 2-megapixel image is 1920 pixels by 1080 pixels.
go to http://www.shrinkpictures.com/ its a online image resizer and you can set the size and image quality. hope this helps
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.
