Hello,

I want to export an image in 150 dpi and photoshop saves the image with a resolution of 72 dpi. This is with a jpg, with a .psd as format photoshop saves the imagen with the appropiate resolution but smaller.

Why is this happening?

Thank you

It is because you use Export. Export is for web use and DOES NOT SET PPI. This will be shown as a default, depending on the app, often 90 ppi or 72 ppi.

If you are working for print, you MUST use Save a copy or Save as to preserve the ppi.

If you are working for web use, the ppi is not relevant, though many web sites are written by confused people who don't understand, and claim it matters.

In the topic thread linked below, I tested differnt JPEG and PNG output methods to demonstrate which include and exclude PPI and ICC metadata:

PPI data is stored in the TIFF namespace. You can use EXIFTool or File Info in Bridge/Photoshop to see if that metadata is present. It should look like this in File Info:

<tiff:XResolution>96/1</tiff:XResolution>
<tiff:YResolution>96/1</tiff:YResolution>
<tiff:ResolutionUnit>2</tiff:ResolutionUnit>

Since I've determined that; If I download, transfer, import, export (or whatever we are calling it these days) my 200 DPI images from my Samsung Galaxy Ultra to Photoshop; PS will automatically turn my large file into 72dpi.

If I go to “images size” in PS can I safely change it to 200 (Samsung’s maximum image capture) without loosing quality of the image?

If you read the full thread you will see that Export does not "change" into 72 ppi.

What it does is to strip the ppi number from the file altogether, because it's not needed for web/screen/mobile devices.

The 72 number appears as a default value when the file is reopened into Photoshop.

As long as you don't resample, you can set the ppi number to anything you want. Nothing in the file changes.
