Ok I'm sure this was asked before, but I can't find it in the forums anywhere. Damn archives are huge. Well does anyone know what the dpi in photoshop is? I mean you can already create an image per pixel so whats the dpi? I mean isnt that the same thing? Can anyone help me out with this, it's been bothering me since I started using photoshop years ago but I never asked about. Well thanks. |

DPI is basically printer related.. Its how many dots(Pixels) are per square inch.. The higher quality print you want the image to be, the higher you up the DPI... If your thinking about printing, 300dpi is pretty good... but if your working solely for computers, your finished peice should be 72 dpi(monitors view images at 72 dpi). A lot of people like to work in a higher resolution and sample it down when done... I think I made sense, at least I hope so.
Regards,
Jesse

I posted this in another thread:
Quick dirty explanation of DPI:
You usually need around 300 ppi (pixel per inch) image resolution for print.
That is if you make a new canvas in photoshop and make it 1" x 1" at 300 ppi (dpi) the image would be 300 x 300 pixels.
If you make an image 3000 x 3000 pixels at 300 dpi it would print at 10" x 10".
Change the dpi to 240 and the same image will print at 12.5" x 12.5".
REMEMBER!: to uncheck "resample image" This will change pixel data.
This concludes that dpi is irrelevant when working on the screen but highly relevant when outputting to print!
Ask away if you need a better explanation.
