The question here really resolves around what you mean by "quality", followed closely by needing to understand what RAW really is and how it relates to other image formats. On the first TIFF is generally not compressed in a lossy way, so artifacts weren't introduced. By that measure, quality isn't degraded in the same way it might be with JPEG (and ...

The only advantages to saving your RAW files as 8-bit is for memory conservation or if certain tools only work with 8-bit images. There is no advantage from a quality point of view, if you're going to do a lot of editing especially in a wide colour space then you may get posterisation when working with only 8 bits. Regarding colour spaces, it is advisable ...

The comments have really answered the question here: The behaviour you're seeing is as you should expect. The settings for adjustment layers alone have no equivalence in any of the TIFF content standards. TIFF does allow for vendor specific extensions and this would be an example of one but saving to a nonstandard TIFF would be pointless if nobody could ...

I would say this is most likely happening because either: the software you are using to print the image is scaling it down prior to sending it to the printer or the selected printer driver settings are set to scale down the image before printing If I were to guess, I'd say it was the first option. Digital images are made of pixels, which don't have a ...

RAW files are 12 ~ 14 bits. I'm pretty sure he knows that. Why an 8 bit TIFF? This was a given for him, so I'm puzzled. The higher bit depth is certainly safer for major corrections of exposure, contrast etc. I would especially be cautious when using ProPhoto RGB that may have tendency to posterization in 8 bit. But 8 bit may be enough for his type of ...

If you saved your TIFFs with 16bit per color channel, you didn't loose any quality. If you saved them with only 8bit, then yes, you lost color resolution, just as with a high quality JPEG. (the TIFF is losslessly compressed, so you don't loose anything by that, but a JPEG with maximum quality isn't noticeably degraded either).

The idea is that you don't want to be applying compression to the image that will result in reduced quality. Tiff is a lossless image format and so it will preserve the raster data perfectly fine. I'm unsure about ProPhoto RGB as I've never worked with it. The one thing that is worth noting is that you will need to make sure your adjustments to your RAW ...
