Regardless of what you WANT, this should be done in Photoshop.
As far as I can reason, doing it in photoshop seems to be adding to much hassle and is essentially an illogical process. It may be that it's the only way at the moment, though :-(
To achieve this effect using Photoshop I would have to add the frosted glass look to the text box (just a rectangle, really) using a blur, then layer that on top of the image to make sure that it looks right, then import them both into InDesign, then add a transparent text box on top of the image with the fake text box (really just a rectangle, after all) I created in photoshop, then when I realize that I want to change the size of the frosted glass text box, then I have to go back to photoshop and change it all again and re-import it back into InDesign. I suppose using smart objects would be make this process a little better, which is good. but.....
If blurs existed as an FX in InDesign, then all I would have to do is select the fill of the text box and add a blur. Boom. Done.
Please let me know if I am not understanding this workflow correctly, or am missing something.
hmmm....guess I should make this a feature request, now that I think of it.
Thank you for taking the time to reply Bob :-)
You can make a feature request if you want but you'll need to make damn good
business case for how it will benefit all users. Keeping in mind that with
Creative Cloud everyone has access to everything I don't think you should
hold your breath waiting for something that Photoshop is designed to do.
Agreed. I feel pretty confident that I can make a strong case for separating layout tools from photo editing tools :-)
