I'm running CS3 on a big Mac (I just scrapped off the special sauce and plugged it in.. )
A client asked me to submit files today in the TIFF format. I did a "save as" on a 300 PPI jpeg and chose TIFF as the file type (see Picture #1)...all well and good.
I then clicked save and got a new dialog box asking me for (among other things) IBM PC or Macintosh byte order (see third choice down in the dialog box in Picture #2)
The first time I did this I chose IBM PC byte order and could still reopen the file on my Mac so I'm trying to understand which choice should I make in the future and what is the difference between the two byte order choices.
#2. "RE: Question about TIFF files" In response to Reply # 0
The Byte order indicates whether the platform’s native files are stored with least significant bit/byte or most significant bit/byte first. It’s kind of whether you write your name from left to right or right to left. As Rick said, interoperability between platforms now requires that you can choose either option.
I am noting that you’ve set compression to None. The two middle compression options, LZW and ZIP, are lossless compressions and can be used safely. ZIP compression has always resulted in slightly (by about 5%) smaller files in the cases where I’ve tried them both. JPG compression is lossy and defeats some of the benefits of using TIF.
