How do you create/save an image as 300 dpi?

    How do you do this? Can you use an existing image and convert it to 300 dpi? Or do you have to create an image with 300 dpi? This image stuff is confusing...:D

    For a new image in Photoshop you simply select 300 dpi instead of the default 72. The image size with nothing but Hello World typed in the box was 3.71 M

    I doubt you can up convert unless it is a vector image.

    The standard on screen resolution is and always will be 72dpi. If you are creating graphics for print, then you will want to use a higher dpi such as 300dpi as in your request. You can get away with 150 dpi.

    So, how do you save an image in 300dpi? There are two ways you can do this (rather two results will occur). Say you have an image that is 500 x 500 with a 72dpi. You can go into image size (with the re-sampling checked) and make it 300dpi. This will give you a bigger image but it is probably not what you want. This will give you an image of 2083 x 2083. You will see that it will not change the inches.

    If you want to change to a higher dpi for printing but do not want to change the onscreen image size, then you uncheck re-sampling. Un-checking sampling will give you the same pixel size (500 x 500) but will change the print size to 1.667 inches down from 6.944.

    I hope this helps.

    Cheers,

    Colbyt is right.There is no way you can increase a image size with quality increased.Only if you are using a vector.You can change the dpi under "image size" but to me,it's useless because it's only for print out and the quality is still low.I been looking for a way,no luck.
