Photoshop CS3 New Document Resolution

Question

For some reason when I create a new document in PS3 and then increase the resolution, lets say to 300dpi, the document is created in the default 72dpi resolution. If I want to increase the resolution I have to create a new document with the default 72dpi resolution and then increase it from the image properties.
Does anyone else have the same problem or knows how to fix it?

Answer 1

do you understand what changing that value does? take that 300ppi document fill it with a color and print it.
now create one that's exactly the same in pixel dimensions (568x452) fill that with a color and print that.
does that show you the difference between 72ppi and 300 ppi? for all intent and purpose, there is no on screen difference in the 2 images. the "72" or "300" value is just a bit of what's called "meta" data. data that's not part of the image, but is part of the description of the image. it has no bearing on what you see on the screen. it's only in printing when the resolution comes into play.
another example from my website:

both images shown are the same pixel dimensions (800x600), but one is 72ppi, one is 300ppi. yet they display exactly the same ON SCREEN. they are essentially the same size on disk when you save them. now try printing them... ;)
