P: Photoshop 23.0 - cannot open TIF files, generated in other programs

If the users are warned of the risk of using unsecure files, they should be allowed for Legacy option that enables reading TIFF's by Photoshop. Surely the option should be disabled when first time installing new release, so no one would be suffered of careleslly provided application.

There're enough experienced users who know what they do to decide a way of doing that, at least many from here likely would meet consequences of own action than like to be constrained to look for alternate software.

Yes, I can open them through Bridge/Raw but not edit unless I open in Photoshop *from* Raw and save again - I have been saving copies, not sure how saving this way will affect the image.

I am in the same situation as you. Considering that Capture One is my main processing software, if Adobe does not solve this issue, I would unfortunately be forced to look for an alternative for regular editing of my work. Even if I were to lose some of the features that Photoshop provides, I can't afford to waste the time I waste now, opening every TIFF photograph through Camera Raw.

My workflow involves opening the file from Lightroom Classic to edit in PS. The files I am working with were processed with Capture One, created by a vendor. I am using the Open in Raw from Bridge now but it slows me down considerably. Any hope for the Capture One files to be openable in PS without Raw step?

If that's Adobe's final answer, it's a real shame.

Did you see the official answer? Adobe may not be able to fix the problem. If another program creates malformed TIFF files with a security issue, that would be up to that developer to fix it.

Exactly the same for me when using Starnet++ with the latest version of Photoshop. As a workaround I open the starless image with Adobe Bridge and then open from Camera Raw. I thought it was my error until I searched on this forum 

As I am now paying a monthly fee for a software tool I cannot use, I would appreciate an update from Adobe on a time schedule to fix the problem. The alternative is to cancel the subscription and turn to other solutions.

My current workaround (quite pathetic, but a workaround nonetheless): The old beta version of Photoshop 22.5 can still be installed with the current CC app and opens my TIFF files. It's slow and likely buggy in other respects, but at least it works for the moment.

I have the same problem, tried to install the older version but only 22.5.2 was available and my .tiff file couldn't open on that version as well. This is really frustrating and I hope it gets fixed soon!
