Formatting for Mac Compatible?


I am working on a submission for a company right now. Their email said, "Please format for MAC compatible." Can someone please explain this? I have Windows 98 and Windows 2000. All files are JPEGs. Is there anything special I need to do to make it Mac compatible? I will be burning them onto a CD. Thanks for any direction. I am new to this.

  Jennifer: If all the files are JPEG, they are as compatible with Mac as with Windows. If you Save As Tiff, and apply compression in Photoshop, you get a Windows and a Mac option.

Frankly, no matter which of those you use, any computer should be able to open the file.

So, the company is just playing it safe, in case someone uses some weird software to save images in some weird format that's not Mac compatible.

Cheers!

  Thank you SO much, Peter!!! I will remember that for the future for TIFF files. For this one ... I'm only using JPEGs. Thanks!

  I have been told when saving compressed TIFF files to use the PC compression becuase either a MAC or a PC would open these files but that if it was saved with MAC compression only a MAC would open it. I am currently using a MAC and save all my TIFF files using the PC compression and have had no issue whatsoever opening them on a MAC or other PCs. It's been a couple years since I have tested the other option though

  Jennifer, sometimes an apple will not open a perfectly normal, working JPEG file & it's really frustrating.

If you save a picture of, say a sailboat on a windows OS as a JPEG, the software will write the code for the picture with JPEG commpression & make a file containing that code named "sailboat". On the other hand, some OSX apple software use a filename extension to recognize the file type, & then open the file with the according program.

So save your file "sailboat" & try to open it on an apple, it simply may not work. Rename the file as "sailboat.jpg" or "sailboat.jpeg" & all of a sudden it works fine. If you have used Photoshop for example on OSX, you know that you write your filename & then pick an extension & the computer will append it for you. Apples take extensions much more seriously, but this really shouldn't happen. It's only happened to me once, & I don't know the exact cause from one time to the next. But I have gotten in the habit anyway of writing the filename plus the extension when saving my files on my apple.

  Mac monitors are set at a different gamma then PC 's. Which means that what you see on your PC will look different on a typical Mac. Generally speaking the gamma setting for a Mac is 1.8 whereas a PC is 2.2. You can correct for this on your machine by resetting the gamma on your monitor to match Mac. OR you can go into photoshop under the windows section and change the gamma there and toggle back and forth. It may be no big deal but I find when I create images on the Mac
and they are projected say from a windows system they either appear darker then intended or worse they go flat.
