    I don't think so T.I., I only shoot RAW and this happens to me too.
    I guess what I was referring to more precisely is the opening up of an image, in my case using camera RAW or the Bridge part of photoshop which is similar to lightroom. And I only shoot in RAW.

    When I double click an image to open it sometimes the image has a default size (which of course can be easily changed) of 240 DPI. Sometimes it has a default size of 300 DPI.

    The question is why is this DPI not consistent when opening the image in camera RAW or Bridge. This is a bit of a hassle because people (myself included) may not realize that the image is 240 DPI when 300 DPI was desired, after it is opened in a graphics program. (In my case - Photoshop)

    many thanks again for this good and informative thread

    Okay... ya' got me. I don't have a clue on this one. I'm sure it's something dead simple, but I can't for the life of me, think of what it might be.

    This is such a great forum!
    Why sometimes 240 and 300 ppi?
    The default settings in Camera Raw may have been changed at some point - the default settings are 240 ppi. My printer (Epson 3800), automatically converts input files for printing to 360 ppi and so I have changed my Camera Raw defaults to 360 ppi. Before I had the 3800 I was not aware of this and consequently I have older images at 240 ppi. If your work flow involves your RAW files first being opened in Camera Raw it will always set the ppi to the default of 240 or whatever you have changed it to.

    WOW some progress - thanks so much!!!
    Any idea exactly where I can find these default settings, I've looked though what I think are the obvious places (preferences) and still can't locate them.

    many thanks Matthew!

    What is camera raw? Is it a program? Or on the camera..lol. I'm confused. I have a Nikon so to get it on my computer I use either Lightroom or Photoshop. Photoshop I had to download a file to get my files downloaded. So do I change this 240 to 300 when I'm downloading by chaning it in lightroom and photoshop? Yes, where do you find that option? Does this make sense..lol

    Camera RAW options are available in Adobe Bridge. Under the edit tab (I am using CS3). This gives you only some options.

    If you shoot in RAW format when you double click (PC) a RAW image file (DNG) in Bridge it should open up first in Camera Raw. Here you can apply sharpening and other useful default "actions" as part of a work flow.

    Once the image is open in Camera RAW there is a link you can click at the bottom of the page. This will give you access to the colour space, bit depth, size (if you want to change from default camera resolution) and pixels per inch.

    Once you have finished your camera raw PP (for the most part I stick with what I have set up as defaults), hit open image in the bottom right corner and it will open up in Photoshop.

    I hope this is clear.
