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...

 

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.

How could that not help...? It was exactly what I wanted to know...You're the best, man....Thanks!

 

Is there anyway to do this in Paint, must you have photoshop to do images of this quality, I am looking for the cheapest alternative to make a banner to specs which are 300dpi.

 

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.

 

You can always pay someone to do it for you!

 

To set 300 dpi on a photograph, open the image in Photoshop. Click on the "Image" option in the main toolbar, in the menu that appears click on the "Image Size" option. This will open a window allowing you to adjust the settings of the image. In this box go to the "Resolution" fields.

 

File>Export As is still very much a work in progress and doesn't save the necessary metadata for the resolution.

I would either use File>Save As>Jpeg or use File>Export>Save for Web>Jpeg and set the Metadata to All

 

But you can also study all those materials that are available on the Internet! For example, http://fixthephoto.com/ has a lot of free tips for photographers!

 

This is my try to cover the query. Go to Image>Image Size> Write Resolution: 300, If you don't uncheck “Resample Image”, Photoshop will simply add pixels without adding detail, and the file size of the image is also showing bigger here. After unchecking the “Resample Image”, You’ll notice the file size of the image doesn’t change but it will change the print size.
