I've got hundreds of photos to scan for a historical archive project. I'm using PC, but it's conceivable that someone in the future may want to access these files on a Mac.
Should I save each TIFF in the Mac format?
It's my understanding that PC's can open either Mac or PC TIFFs, but Macs only open Macs. Is that right?

No, it's not. A TIF is a TIF.

Don,
It's been many years since the byte order of TIFFs was of any concern whatsoever. These days all applications can handle either byte order without problem.
#3
Would DNG be better?

In my experience its the other way round. As a frequent user of both systems I have more problems trying to open Mac TIFFs on a PC, particularly when saved to CDs. Hitting the appropriate "byte order" button in the Mac save dialogue definitely helps. Better still - save to a "pen" drive as these appear to be genuinely cross-platform compatible. Good luck.

What's DNG? Do you mean PNG?
If byte order doesn't matter, why do they even give people a choice?

Don,
DNG is the 'new open standard' for digital images and stands for 'Digital Negative'.

Good question! I don't think there is a god answer to go with it.

Thanks for the responses. When I did a google search on this question the other day, I got really confused. Most of the info I found was from a couple years ago. It made this byte order thing sound like a big deal.
I'm not brave enough to switch over to DNG at this point. I'm also planning on bringing the TIFFS into my video edit software. Not sure if it takes DNGs.

The TIFF standard, unlike some previous standards, was designed to accommodate both Motorola (Mac) and Intel (PC) byte orders. It includes a data element that records which byte order was used in creating the file, and thus a program reading the file uses this to determine which byte order to use in accessing the data. It works equally well on either platform. If an Intel CPU is being used to read Mac data, the program simply uses a routine to flip the bytes around, and vice versa. Any program that doesn't have the ability to access both flavors of TIFFs in this day and age should be discarded fast.

IIRC
The TIFF file actually has a passage that requires that any program must be able to access both flavors of TIFFs in order to be considered "compliant."
