Different Scale factor when doing SAVE AS and SAVE FOR WEB - on Windows?

Are you follwing this up in the InDesign forum? This still feels like an ID bug to me. Especially if these jpegs behave correctly elsewhere.

I don't know this, not being very proficient in programming, but it seems reasonable that size calculations happen on the receiving end. The ppi metadata in the jpeg is either there or not.

And it doesn't have to be a square - 4096x2048 and 2048x4096 - still places scaled down.

So beside the fact, that Mac is also affected - there is more:

Multiplies of 1024 - are always affected.

Looks like f) should be:

f) InDesign - Mac - correct wrong import of d)

And that's current conlcusion:

a) Photoshop - Win - bad JPEG when doing Save As 72ppi

b) InDesign - Win - wrong import of a)

c) InDesign - Mac - wrong import of a)

d) Photoshop - Mac - correct JPEG from Save As 72ppi

e) InDesign - Win - wrong import of d)

f) InDesign - Mac - correct import of d)

And one more thing - InDesign CS6 places correctly ...

JPEGs created on Mac - placed on a PC:

72, web, 96:

Got it. Sorry if I seem to be speed-reading and misunderstanding these posts, right now I'm just doing this while waiting for other things to process. That usually works well for more trivial questions 😉 But this wasn't as trivial as it first seemed.

Since no one else seems to respond, I've been trying to follow up, but hopefully someone else can pick this up.

Still - maybe you shouldn't confuse the issue by bringing Illustrator into this. In fact, it seems to me that this belongs in the InDesign forum, not the Photoshop forum. The bug seems to be an InDesign bug, not a Photoshop bug.
