Ok...I have been processing a batch of wedding pictures with PSCS2 and just noticed that the default tiff setting when I save it is "LZW" compression. Could someone tell me if I should be using this, or should I be changing the default to "none". And more importantly am I going to have to redo all of the edits I have done and saved at the LZW compression setting. :(
Any light someone can shine on this would be appreciated!! |

You're OK. LZW is a "lossless" compression. It just makes for a smaller file size, that's all. It may take a tad longer to open, but with today's processors, its hardly noticable.

| Whew...I was hoping it was "lossless", but started second guessing myself and envisioning an awful amount of repeat work! :) |

This is completely true as it applies to opening the file with an image-editing program. LZW can occasionally cause problems if you are placing the photo onto another page (for example, with a layout program like Quark or InDesign) and try to print it from there. I always try to open and re-save a TIFF without the LZW if I'm using it that way. |

the only trouble i've had with LZW compressed files using XPress is that if its a greyscale image it sometimes gives a postscript error if the image has been given a colour inside XPress..
i find InDesign far better at handling images than XPress (XPress has a slight edge over InDesign with the speed that it draws a page)but got to love the fact that you can drag a PSD layered file with a transparent background into InDesign and it will display the same as in Photoshop :D
with LZW compression you'll have more of a delay writing a file than you will opening it.. its more about disk access rate these days than waiting for the CPU.. |
