    Smile image resizing for prints

    Hi , i would like to ask


    i want to resize some jpeg images for print say like 8r, 10 by 15 and 16 by 20.

    is it possible to use photoshop and change image size accordingly or need to crop the original file according to print size?

    for a 4R (4" x 6") print
    your image size for good quality should be 1800 px x 1200 px

    4" x 300 px = 1200 px
    6" x 300 px = 1800 px

    simple right?
    so do the same for other sizes
    whether or not need to crop depends on you

    Erm.. but you know that cropping and resizing is something different?
    Resizing: keep all content of the image, 'squeeze' it into smaller size
    Cropping: cut off parts of the image so that the remaining part is of smaller size.

    Decide what is necessary, Photoshop can do both.

    some paper size has different ratio, so you need to crop to the corresponded ratio before resizing, else image will be distorted.

    eg, the ratio of 4R is 2:3, 10x15 is also 2:3, and 8x10, 16x20 are 4:5

    Best to maintain the ratio...

    another tip is remember to use bicubic smoother for enlarging and bicubic sharper for reduction.
