PPi from my cell phone camera
Hey guys. I was wondering about this since it doesn't make a lot of sense. I have my default image to open at 300 ppi but it still opens pictures straight from the camera at 72 ppi. My camera specifications statte that the default image should be roughly around 312 ppi, so why is it opening them at 72 ppi? This isn't the native resolution and the default of GIMP is being told to open images at 300 ppi, so why is it still opening it at 72. Thanks.

Gimp does not care about ppi which only really comes into play when printing or browser display.

It is the number of pixels which count. If you go into the view menu and untick dot-for-dot. That setting maps one image pixel to one monitor pixel (traditionally 72 ppi). Then you will see ppi settings take effect.

edit: Here we are hot of the press

This is the same image opened twice, both 100% zoom, left hand dot-for-dot off, it is 200 ppi so it displays about half the size of Gimp default dot-for-dot on. Note the top the only thing that really matters is the size in pixels. A lot easier to edit with dot-for-dot on.

RE: PPi from my cell phone camera
So can I photo enhance a photo at 72 dpi then before printing just change it to 300 ppi and it will come out nice and clean? The printer people say you can't do this and it used to open them at 300 ppi on a different camera if I remember correctly. Im starting to want to make prints and I have to make sure they are nice. Thanks.

Again, gimp is a pixel editor, you can wreck your image but with your editing.

The settings such as ppi are called metadata, not part of the image.
If the print house insist on using the ppi which is set.
Before you export the finished result go to Image -> Print size and check that it is still 300 ppi, If not change it to 300 ppi if that is what is needed.
