That produces images over 300 DPI?

| Sure, any digital camera can. |

DPI is a measurement that is relative to the size of the paper you want to put the image on, so the answer really depends on the size you wish to print at. DPI is only an abstraction until you print.
A US letter size page at 300 DPI would be 3300 x 2550 pixels, which is about 8.5 Mp
A 4x6 print at 300 DPI is 1200 x 1800 pixels, which would take a little over 2 Mp to produce.
If someone is telling you they need your images at a certain DPI, you will need to know what size they will be printing at in order to figure out the correct size in pixels.
Hope that makes some sense.

That does make sense to me but I wanted to just make sure I knew what I was talking about.
Here's why I asked. This Magazine editor was saying that they print at the lower end of the high resolution scale and I asked her what they were printing at. She told me that she wanted at LEAST images that were 300 DPI and I was thinking, as far as I know that is as high res as you can go. I asked her what she thought was high on the high res scale and she said like 1200DPI... is it just me or does that sound like she is getting something mixed up here???

Most people can't get it that the "P" stands for DotsPerInch -- it has (as mentioned) only to do with the final output size; 300 pixels are 1" at 300dpi, but 3" at 100dpi and 6" at 50dpi ...
Just ask what is the largest size they intend to print it at, and make sure that when you set the image to 300dpi (without resampling) it exceeds those dimensions.
BTW: For strictly Black&White line drawings, cartoons, text, etc., 1200 dpi is a recommended value, but not for photographic images. |

300 DPI is a normal resolution for your garden variety laser printer, though most printers and MFP's are now printing at 600 DPI. 600 is the point of diminishing returns for xerographic technology. Due to the limitations of the paper and other variables, most people will not see the difference with anything higher than 600.

| If it's for a magazine it will almost certainly be printed by an offset lithographic process with a 150-200 line screen (NOT the same as DPI!), for which a 300dpi file (up to 400dpi) at finl print size would be appropriate. |

Magazines print images at double the line screen used on their printing presses. These days, that's usually 150 lpi, so they'd ask for an image that's at least 300dpi. By default, most/all cameras record images at 72dpi because that was the standard monitor resolution (before LCD displays), but a large image at 72dpi is the same as a smaller image at 300dpi (as long as you don't resample it when scaling). You're only changing the density. A full frame image from the, um... Mattel Barbie D40X has a resolution of about 8.5x13" @ 300dpi. Note also that you can safely res-up a sharp photo about 15-20% without significantly affecting print quality.

okay okay now I understand what they are talking about. I mean I'm not new at understanding standard PPI/DPI and print resolution but for some reason it just sounded like my max 300dpi images were"small" to them... But I'm good, they are getting all the raw files anyway so whatever right.
Thanks guys.
