Indesign - Resize Image to Specific PPI
If I paste/place a large image (72 ppi) into Indesign and want to scale it down to be equivalent to 300 ppi, is there a way to do that in just Indesign?
I know I could figure out the scaling math, or change the settings via Photoshop, but I'd prefer something automated if possible.
My experience is that inDesign will use the ppi flag in the file to set the initial print dimensions if you do not drag the box when placing the image.
For 72ppi-flagged images, you will always need to reduce the print size by 24% to arrive at 300ppi (effective). Since 72/300 will always be .24, you don't need to do the math more than once.
Place the image at 100% (place> then click without dragging), then immediately change the size to 24%.
Changing the dpi setting (without altering the pixel dimensions) in Photoshop is a formality.
