Reply To: Image degradation on resaving from PSD to JPEG

I also tried to do a sort of a trial. I did a Save as & I saved a single image as both JPEG & PSD. placed about 30 JPEG images in 1 Indesign document & 30 PSD images in another Indesign document. Though each PSD was on an average 1.2 MB bigger than the corresponding JPEG image, the final size of the exported PDF of PSD-containing images was only 1.6 MB larger than the exported PDF of JPEG-containing images. So, PSD definitely scores over JPEG.
