Hi there, Im tryin to downsize 180dpi images into a 72 dpi document and every time I do it I lose all quality.

Ive tried JPG / EPS and GIFF file types – The files I am trying to down size without losing the quality are 15 wide x 10 cm – 180 dpi. And the area I am dropping them into is approx 12cm wide – 72 dpi.

What am I doing wrong???

Thanks so much

By definition, reducing the number of pixels will reduce the quality of the image.

What are the pixel dimensions before and after? That will give you an idea of how many pixels you are throwing away.

What is the final output? Unless it’s for printing the "physical" dimensions, cm or whatever are irrelevant. Pixel dimensions are what counts.

If it IS for printing, try TIFF, not the other formats.

Try Resampling (Image Size) with Bicubic Sharper.

PS: What version of Photoshop are you using?

Im using CS2. The pixel dimesions started off at 2.25m and are now 63.5k … quite a drop.

I just want it as a good quality picture to go onto a dvd cover, I think Ive tried eveything … I hope I havent though …

That’s not pixel dimensions, those are file sizes.

Pixels dimanesions are something like 2000 pixels x 3000 pixels

If it’s being printed, you should NOT downsample. 72 ppi is not for printing

Not for a DVD cover, but plenty for a billboard.

And where is it going? You said it was going into a 72dpi document. What kind of document?

This kind of thing is best done from a page layout document like InDesign or Quark Express or in a pinch Illustrator or Freehand. Printing a CD cover from Photoshop is not ideal, but if it’s done I’d shoot for 300 ppi or more.

Ive modified an image that was 72dpi then brought it into a 30 x 20 cm document at 72 dpi and the new files I am trying to bring in also, but ofcourse they are larger – they are 1024 x 768 and after the downsizing they are 142 x 116 – very pixelated.

Is there anyway to optimise the quality??

Have you been paying attention?

If you have, have you understood the advice?

If you’ve got time, read this:

Well, in a way I’d say you are screwed, but depending on what the 72 dpi document looks like detail-wise, etc. I think your best bet would be to increase the resolution of the target document rather than the image you are going to put into it. As previously noted, 72 dpi is not good for printing a DVD cover.

You should not be reducing the image resolution it going to print. Just stop resampling.
