Tiffs are a non lossy file format, and therefore there is no loss of data when saved. JPEGS on the other hand are a lossy format and in order to compress the file to a smaller size data is lost

Re: Tiff

TIFFs are also generally the prefered format for print publications.
But they are a lot bigger than JPEGs.

Usually I'll shoot in RAW and save a version in PhotoShop's native format then do a TIFF for magazines and a JPEG for web.

Since I've started using Apple Aperture it's done away with the need to physically save different versions, but I still do to some extent.

Re: Tiff

Use TIFF, if you need to upsize a photo, e.g a 5MP photo to 10MP.
Otherwise I don't find any need for using it, since it creates very large files, and differences in normal prints or monitor views are negligible to the point of not distinguishable at all.

Not strictly true

TIFFs can contain either lossless or lossy image data. TIFF is really a standard for containing image data. A JPEG format lossy image can be contained within a TIFF file. And you can have multiple images in one file, like a thummbnail, medium size and full version of the main image.

But in photography, TIFF is almost exclusively used and perceived as a lossless image file format. TIFFs can be losslessly compressed, but this type of compression is not efficient with full colour photo images, so the files remain large.

Trust a techy to complicate matters
TBH I have absolutely no need for the format at all, as if I wanted an archival non raw format I would be inclined to use PSD files

I use PSD for archiving, especially with layers, Tif for publishing, and PHOTOSHOP EPS/Tiff 8 bit Pixel/Jpeg Maximum for all my final print output, which I only save for printing, this mean I only open and close without save. I've yet to see any difference between this and the Tiff (only for printing and no re-save purpose), most PS EPS files is only 1/6th size of most Tiffs.

Re: Tiff

Just out of interest, why do publishers prefer tiff over psd? I assume it's because the majority of software packages handle tiffs whereas psd is not so widely catered for?

I currently save all my photos in tiff format (after converting from RAW which I also save) and would welcome the size advantage of saving to psd but I've always thought of psd as proprietary?

Hi Danny.

Doesn't TIFF support layers?

Re: Tiff

Many thanks to you all, comfirms what I thought.

Re: Tiff

Not sure why publishers prefer TIFFs.

I'd imagine it's because TIFF was about before PhotoShop and has along with EPS, become the 'standard' file format for graphics files. QuarkXPress which is the main desktop publishing software only recently became able to handle PSD files as standard. PSD is also a proprietry format, TIFF isn't.
