images for mac and pc

[bazz]

Hi,

I have been told that photographs put onto cd and to be used on MAc's have to be in a different format from those which are to be used on PC's. Can anyone explain it to me?

I will be taking photographs and supplying them both to online users and hard copy publishers. Apparently .jpeg isn't suitable for MAC, which is what most hard copy publishers use for required extra clarity of imaging.

Whoever told you that is totally full of st.
If the images are going to print, or don't need to be compressed (such as your case) then .tif is a far superior format. It is recognised by all systems (Linux? not sure..) and in Photoshop 6+7 you can save layered tif files that are still standard, flat images for every other program.
.Tif is the way to go.

As for the CD, just make sure you burn it as the ISO 9660 format, and a Mac will have no problems with it.
Personally, I'd ignore anything else from the person who told you mac's can't read jpg's.....

Thanks MindlessLemming.

It was akchewaly a publisher who said to me not to send him PC format imagery as they can't get the clarity for hard copy presentation such as brochures etc. He said that this is why nearly al publishers use MAC. I also recall getting a CD of a hotel's pictures and they didn't have the usual .jpg or .tif (or whatever file names. They looked like this:

royalccp.ark
bigdinin.gro
royaldin.ing

why is this? IIRC I had to rename them all to jpg before my windoze PC (or the software I was using), would recognise them.

That's because Mac's don't rely on archaic file extensions to determine the contents of a file. Therefore, they don't need extensions and this can cause things to turn to many flavours of bad when you try to open them on a PC.

This isn't a pro Mac rant, I've never owned one of the things, but I know what Windows does poorly.

There's no point this becoming a rant either since my clients use both so I must provide for both types.

In a nutshell then, if I save my images as .TIF .png ,jpg or .jpeg they'll be readable in pc's and Macs Yes??

Yes.
Tif is the best,
Png next, but it has some support issues with IE+Windows.
then .jpg

In case they're using dinosaur computers, save as jpg instead of jpeg

[bazz]

excellent.

Thanks very much

FYI -- if you are using these images for print don't save them as a png, jpeg, or gif format. All three limit the color quality and file size of the image. Save them as Tif or photoshop eps files (you can do bitmap and photoshop native, but they're so huge, it's almost worthless). Us geek print designers need high res files that have not lost any color quality -- you get a nasty saturated image that has some banding
