Do .psd's behave like .fla's?

[FluxCapacitorClock]

Like, if I make something in Photoshop CS3, will it open in an older version of Photoshop?

[skeletal]

No I don't think so, whenever I've made something at home and taken it into school it wouldn't open on their older versions, although I could have just been doing it wrong.

.psds were only integrated in CS3. 8 and below are out of luck.

I have CS2, and those files open in older photoshops, granted it doesn't have smart objects or other new such features in it.

Psd stands for Photoshop Document and I'm pretty sure it's been like that always.

I know what it stands for and I'm pretty sure they just added it into cs3, but I'm probably wrong

he's talking about opening a newer photoshop file in an older version of photoshop not opening a .psd in flash.

[SeedClock]

ive had lower ones along with cs3 and all images will open but some parts of your image will be filtered out because of conversion problems

I do stuff with photoshop CS3 at work, and can open it up with CS1 at home. It will work, although maybe if you used something like a gradient layer stroke, it might not like that. I think if it can't load the data it uses existing pixel data, I know it's true for fonts, but have yet to encounter such an issue with using older versions. Photoshop is not like After Effects, where filters are applied and can be toggled still, they are applied, and rendered the instant you do it.

Shortly put: Yes

[CranberryClock]

The actual file will open, but its treated like Missing Fonts if opened on a prior system. Adobe uses tags in the psd files.

Thus:

insert CS3 only items

then its
insert Cs2 items

thats why the header of the file gets larger and larger every version.


TL;DR:
Yes it will open just not include new features or items associated with CS3 instead it will attempt to rasterize the layer into an uneditable mask or corrupt the layer beyond use.

You can save as a PDF, those go all the way back to flash 5.
