P: support for un-maximized PSDs

I don't know that you get it. Layers, in TIFF or PSD are proprietary Adobe data. If you are worried about access to that data in an Adobe app, either will work the same (san's Dutone support). OUTSIDE Adobe app's, TIFF or PSD, the layer proprietary data isn't available. That's why we need a flattened version! Outside Adobe app's, TIFF is vastly more supported than PSD, and both will only provide a flattened version of the proprietary layer data for editing.

Maybe it's foolish, maybe it's superfluous, maybe it's even obsolete. But certainly it's *being used*. And that's what matters.

On top of that, like I've said a million times, TIFF doesn't work properly in each application that claims to be able to read it. Those programs almost always only read the first/top layer, and don't apply any of the effects that you could do in Photoshop, like adjustment layers. I seriously doubt that any program capable of reading TIFF would go and implement all of this. It's too much work and TIFF is almost never used like that anyway.

All this makes TIFF certainly usable, but it also makes for faux compatibility. Which is useful if your files remain inside the realm of Adobe. Anywhere outside it and they become unreadable and write-only.

Therefor, PSD. At least PSD is unsupported or supported. Never anywhere in between.

And if TIFF is so equivalent to PSD, like (as well) I've said a billion times before: implementing it in Lightroom should be trivial, if it already supports TIFF to its full extend as you so claim (which I seriously doubt - so prove it).

It's foolish to use PSD, end of story. It doesn't provide anything useful as discussed, it's proprietary, it's far less supported on other applications. There's no reason for Adobe to waste engineering time and resources so yes, good luck in getting this requested implemented. I suspect that if you asked most Adobe engineers if they would personally prefer PSD to go away, they would say yes.

I don't understand this.
You're wishing me good luck with what exactly?

Good luck

I don't care about votes. A long discussion says a lot more. I think Adobe is intelligent enough to disguish between what's important and what's popular.

More to the point, if TIFF and PSD are so similar, then it should be all the more trivial to get PSD working.

In two years, this topic has received 3 votes. That probably tells Adobe they don't need to waste the engineering time to reverse engineer the PS engine into Lightroom just to satisfy a few.

Some additional research in to Tiff vs. PSD on your parts, is probably in order. The functionality you perceive you are losing is so miniscule that the benefits of Tiff dwarf them by comparison. I have never met anyone who wished they hadn't converted over to TIFF but I have met plenty who lament having stayed (or converted) to PSD.

On top of that, even if TIFF supports layers (properly), most applicaties cannot read them. So might as well have PSD for full functionality, rather than a crippled version in TIFF.

Besides the hassle of knowing which file is in Layers and which is flat. If it has layers I use PSD, if its flat I use TIF.

Not choosing "Maximize compatibility" means not properly saved, and Photoshop's dialog box does provide a very clear indication of the likely results in other apps.

It's "fairly trivial" to read the embedded preview which "Maximize compatibility" adds to the PSD, and that's what LR and other 3rd party apps use. It's not so trivial to include Photoshop's rendering engine and can't be a high priority to cater for folk who have deliberately chosen a suboptimal method of saving files.

Your best bet is to write an action to convert PSDs to layered TIFs. TIF is the equivalent of PSD - with the minor exception of not supporting duotone mode images.
