Dear Richard
Please read my posts. I didn't say that Jpeg and Tiff weren't invented by different people. I didn't say that Jpegs were lossless.
Open a Jpeg in PS and although it appears as a Jpeg and will re-save as a jpeg it is identical to the Tiff file you get when you save to Tiff. Try saving it as a Tiff and tell me what the difference is? As far as I know the only differences, when open, are in the tags. Change the one that says 'I am a jpeg' to 'I am a Tiff' and that is what you get.
I also know that there are several different Tiffs, those that read up and down and those that read left to right for starters. In the context of Mike's post and for all practical purposes I haven't said anything wrong.

Sorry you are still wrong here. A JPEG file is a totally independent format from
TIFF.
A JPEG can be converted to a TIFF but it will not improve it. A file in TIFF
format can be opened in something like Photoshop and saved as a JPEG, but then
you compress and lose depending on your setting.
But I'm afraid they are not the same thing.
cheers
Richard
