    I'm trying to figure out what DPI to save a picture in for web use. Should I save in a diff. DPI for an image that is 1024x683 than 500x333? 120 DPI? 72? 300? I'm lost. What will give me the maximum for web use?

    I don't really understand the DPI thing fully but I think that's from mis-information on forums. I don't think it will make a difference, the resolution is what it is.

    DPI only matters when printing as they can print at different resolutions. At least that's how I'm understanding it.

    I'll never understand it either. I can't stand it when I'm working with customers at work that request some sort of picture in 300 dpi. it's fucking stupid.

    is this for web or print. I like to to save at 300dpi for print and 72 for web. 72 only cause it seems to be a photoshop default.

    However, I try really hard to not "create" create pixels through interpolation methods just to have the desired DPI. but generally I can set my image to a size that would be a normal print size like 8x10 instead of humungous size and th dpi will go up automatically. generally I wont print bigger than this so I am fine.

    However, this is for my processed or output image. I never alter my original

    Monitors display at 72dpi, no matter the setting in the image. DPI is really only relevant for printing.

    for example.

    a 200x200 pic @200dpi, will show up on a monitor taking up 200x200 pixels. it will print 1"x1".

    a 200x200 pic @100dpi, will show up on a monitor taking up those same 200x200 pixels, but will print 2"x2"

    these numbers are not any kind of recommendation before people try to go on about how prints should only be whatever dpi. its just an example with easy numbers to get the point.

    dpi can be changed without wrecking image quality.

    go into photoshop take that 200x200 image thats at 100dpi, and change the dpi to 200, but remember to change the pixel dimensions back to the original 200x200, before clicking ok. the print will look different but you have not lost one single bit of data from your original image.

    I always use 72dpi if saving for web, with no intention of printing.

    dpi and ppi are different.

    dpi is only relevant to print work.

    If your customers request work in 300 dpi, it's you that stupid and can't recognize that they plan on printing that image, even though you only gave it to them for the web.

    I can print a 1200x800 300dpi image 24"x36" and no one would ever know I didn't print the raw image.


    Here's a link.

    depends on how you save em.

    I have my raw set for 360 dpi, prophoto colorspace.

    It's more common to see 240/300 dpi abobe RGB.

    My 300D was 180dpi off the camera.

    My 20D is 240.

    You realize DPI has NO meaning until you print something, right?

    I could have the same picture saved at 2 DPI and at 20000 DPI and they would look the same if I posted them here because the only thing you see are pixels. DPI ONLY matters when you are printing.

    I volunteered to help shoot some pictures for a non-profit org here and they requested my pictures be 300 dpi (to print on flyers or newsletter). I have no fuckin clue what it means.

    So I guess DPI does matter now. :hsugh:

    It doesnt matter.

    DPI is MEANINGLESS WITHOUT A PRINT SIZE

    For example, one of the papers I work for requires submitted pictures to allow for 200dpi with 8" on the long side. All this means to me is that the long side of my picture has to be 1600px.
    DPI means NOTHING until your picture is printed. The DPI along with your resolution determines what size print you are going to end up with. Along the same lines, desired print size and desired DPI determine what resolution file you need.

    If someone is simply saying, "we need your pictures to be X dpi", then they dont know what theyre talking about. If theyre the ones printing, theyre the ones deciding the DPI
