Well there you have it OP, an answer to your original question and a range of views / issues on file formats.

This is as it should be. The reason is the limitations in the jpeg file format specification.

 

You have saved a layered file as jpeg - but the jpeg specification does not support layers. So it has to be a copy.

 

The original layered file remains as the jpeg copy is saved. The jpeg cannot replace the tiff because it cannot contain all the properties.

    Dag – do you use TIFFs for your high quality work?

    Personally I keep all my masters PSD. For use in Adobe applications exclusively, sticking to native formats is probably the safest choice. But TIFF should work equally well, AFAIK it supports everything (except it may be a little limited in InDesign).

     

    But jpeg is a different kind of animal. It's for a whole other purpose, and it basically doesn't support anything. The minute you start doing something to an image in Photoshop, it's outside the jpeg file format specification. Not to mention the compression. So it's completely out of the question as a working format.

    IMO there is rarely a need to save a PSD file as a TIFF – TIFFs file are very large, the quality improvement over JPGs is imperceptible, and compared with an uncompressed JPGs and they have limited use. Unlike TIFFs, JPGs can be used in all applications, so distribution to others works in all applications, the format will be accepted by photo bureaux, and they can be used in websites. There are features of TIFF that might be used by some, but not for the general user.

    Keep images as native PSD files (in RGB color mode) for placing in some applications, such as InDesign.
