File size gets giant when creating canvas size 4x6 and small pic - Adobe Photoshop 7, CS, CS2 & CS3

I have a color negative scan that is a 64MB TIFF file. I crop and edit it and it turns into about 54MB. Then I need it to be 1.75in x 2.25in and print in the middle of a 4x6 sheet, so I turn the canvas size to 4x6, leaving the smaller image in the middle of the canvas. When I do this, the file size turns into 260MB. That doesn't make sense, nor can my camera store print a file that large. Help!...

    Bill,

    An image 1.75" x 2.25" should be about 664Kbyte ONLY.

    You need to re-size the image from Image>Image Size with re-sampling ON and
    a resolution of 240 ppi to 300 ppi.

    You will probably need to apply some Unsharp masking following the
    re-sampling

    Bill check the resolution... chances are it was scanned at a higher dpi than
    you actually need eg... 4000 or 2000 dpi... and that's the size you're
    working in.... so, when you increase the canvas to 6x4in it's 6 x X dpi by 4
    x Xdpi. Therefore... You need to reduce the dpi of the image....

    The other possibility is that your image was scanned in 16 bits per channel
    colour and you haven't reduced it to 8 bits per channel. In which case,
    reduce the bit depth to 8bits per channel.

    Cheers...

    I need to print this and give it to the camera store to print. The Yearbook staff will then take the print and use it for the yearbook. I don't know what they're doing with it, but probably scanning it. They won't take a digital image. What resolution should I use for that?

    either print the 1.75x2.25 image to a regular sheet and trim by hand, or set the paper size to 4x6 and print the 1.75x2.25 with image centered (print w/preview). your problem is you're adding all that blank area to the image's actual size and that's causing the file size to grow accordingly.
