Is Tiff format lossless, no matter what Program you use?
I have a free software I got called Ulead which is not comparable to
photoshop. However I can still edit some picture for a book we are publishing. It allows me to save my edited pics in tiff format. Is this format lossless no matter what software you use. So I can re same as many times as I like without degrading the picture quality? thanks. |

TIFF can be lossy depending on the settings you choose, just make sure you check the coices to do lossless saving. |

TIFF can be lossy depending on the settings you choose, just make sure you check the coices to do lossless saving. I'd be interested in hearing how you can make it lossy without going to extraordinary effort. TIFF is a container format that can encapsulate many types of image data, but typically it will contain 8- or 16-bit RGB image data with or without optional compression, all lossless. For all practical purposes the answer to the original question is "yes, TIFF is lossless". -- John Bean |

Have you ordered a K20D yet? Cheers. Pete |

TIFF has no standard compression, so either lossy, or lossless, compression could be applied to the file. Generally TIFF files are compressed with LZW compression, which is lossless. |

Not a D or a K10D. The DS that I have is a second-generation design using the same sensor as the D and was was not on v1.0 firmware when I bought it, and the K100D is third generation using essetially the same hardware; it's the sensor more than the body itself that I wouldn't buy in "Mk 1" form. The K10D is a good example - it suffered from some noise problems that weren't present in any of the earlier Pentax cameras and it wasn't entirely fixed with later firmware. Not that it isn't a good performer in its class, just that in can't do some of the things I use my DS for because of the relatively poor high-ISO performance. None of this was discovered until the camera was in the hands of users. That's what I meant by "never buy Mk 1 hardware or run "V1.0" software - I'll let others shake the bugs out before I even look at the possibility of buying one. -- John Bean |

There is a TIFF format where the image is encoded as a JPEG, which I assume is usually lossy. If ULead supports this (which I doubt), I'm sure they'll also support lossless TIFF formats. |

Gimp: "Save as...", select TIFF, set compression to JPEG. PhotoFilt No options whatsoever. Paint.NET: No options whatsoever. IrfanView: "Save as...", select TIFF, set compression to JPEG. So far, 100% of the programs I checked either provided no way of selecting the type of compression at all or provided JPEG among the available compressions. For all practical purposes the answer to the original question is "yes, TIFF is lossless". For all practical purposes, when a beginner asks about a procedure where it's easy to make mistakes ("Look! By selecting JPEG and 50%, my files get so much smaller!"), it's advisable to make clear how to avoid those mistakes. -- Toke Eskildsen - http://ekot.dk/ |
