why do some models use tiff instead of bmp and jpg . what function or benifits does it do differnt then the jpg or bmp?or what the right circumstances to use a tiff?

Did Poser 3 just use TIFF's? I forget. TIFF and BMP formats are uncompressed, the only difference I can think of is that TIFF's can take an alpha channel. However that is not used directly in texturing, so I can't think of anything between them. JPG's can be compressed so there can be a saving in performance, the trade off being clarity.

thanks philc your 3D stuff rocks

Just how does one "stuff a rock?" Inquiring minds want to know (unsigned) ;=]

that some california lingo it means his 3d art work is really sweet

You can also use a .png file in Poser Pro Pak and Poser 5.
It uses a "loss-less" compression scheme, so you can keep the clarity and save some space at the same time.

The compression isn't as great as a .jpg but the images aren't degraded either.

Tiffs can be compressed, but an uncompressed tiff shouldn't be any different in image quality from a bmp; tiff has a larger header (tags in a tiff) than a bmp but allows for more information as in artist, software, date, etc. Tiff also has the capacity to store multible images but I don't know that there is any standard for retrieving these additional images and there is a lot of confusion as to what constitutes a "standard" tiff implimentation. For most purposes you're better off using bmp rather than tiff. png is probably even better for general purposes - as long as you aren't trying to make your own deflate based compressor/decompressor (LOL I actually tried that) and keep in mind that not all existing software takes full advantage of the png specification.
