Jerry,
That Adobe TechNote is also a helpful read. However, I noticed one section that contradicts Mr. Schewe's take on PSD, a subject covered in another informative thread here.
This current TechNote reads:
Flattening TIFF files
Photoshop allows layers to be saved in TIFF files. Layered TIFF files are larger than flattened TIFF files and require more resources for processing and printing. If you work with a layered TIFF file, save the original layered file as an Adobe Photoshop (.psd) file; then, when you are ready to save the file in TIFF format, save a copy without layers.
So, it seems Adobe continues to recommend saving layered files as .PSD (I assume that means editing in PSD as well), which was my old workflow until Jeff wrote his take on PSD.
And one wonders why digital photographers are confused and pulling their last three hairs out.
I see no reason to return to retouching in PSD because I haven't noticed any savings in file sizes. It seems much more efficient to:
1. Retouch photographic images on a TIFF (converted from Adobe Camera RAW)
2. Save the Master Retouch version as a layered TIFF.
3. Dupe the Master Retouch version and Flatten.
4. Prepare the Flattened version for Output.
I know this isn't the subject of this thread but feel free to tell me I got this wrong.
