    Hi All,

    I have some images taken on my 300D

    I need to scale these down to 8 inches x 6 inches - I've tried a few techniques and each time I get a poor quality image. I really don't know the "proper" way to do this. Can you guys help me out ?

    Whats the correct way to scale down images and retain as much detail as possible. The problem I have is lines in the image becoming jagged.

    the only way to understand picture scaling is to realize that measuring in inches has no meaning unless one knows the number of pixels in the picture.

    Most commercial printers recommend that, for small to medium size prints, 250 or 300 pixels per inch will give a great print thus for a 'perfect picture at 8 x 10, you would need an image that is 2400 x 3000 pixels.

    Consequently for an 8 x 6 print (rather an odd size) your image needs to be 2400 x 1800.

    Thanks The_Traveler.

    I just did a pixel-wise scale rather than directly by inches and by doing this I was allowed to set the ppi. Consequently I got a really nice sharp image.

    I agree the size is strange but its not my choice :-D

    Thanks for your help!
