AI giving different dimensions when saving PSD files

Question

Would like to understand what is happening here. I have a PSD file and I flatten it to 4 layers then save the file (but leaving it open in PS) > I go into Bridge , choose that same saved PSD file and open with AI > Save as AI file. The resulting AI file size can be wildly different even thought the settings are the same and the file is saved the exact same way.

Example:

PSD File is 2850 x 2850 @300 ppi

first time I saved this as an AI file is saved as 648 x648 @300 ppi

When I did it again, same file, same settings, same everything, it saved as the same size as the PSD: 2850 x 2850 @300 ppi

waht is going on here? thanks.

Interesting. I looked at both of the examples above with more metadata selected to display and this is what I got:

for the one displayig 792 px Sq @ 300ppi the metadata is showing 6.7 cm sq, but the transform panel shows 19.3 cm sq.

For the one displaying 3300 px sq @300ppi the meadata is showing 27.9 cm Sq. but the transform panel shows 19.3 cm Sq.

so you are right, it seems to be a Bridge thing. Do you think it is giving me the thumbnail size? There is a difference in scale when I hit the spacebar to preview the images in Bridge. the 792 gives me a smaller preview than the 3300 does. thanks for sticking with me on this.

Luckily this does not affect export or print. You may want to check the Bridge forum, maybe someone there can explain it: https://community.adobe.com/t5/bridge/ct-p/ct-bridge?page=1&sort=latest_replies&lang=all&tabid=all

Illustrator just scales the image to honor the 300 ppi set in Photoshop.The amount of pixels is the same, the image is scaled 24 %.
