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 ...

If you have experience of sending files for print in the past and receiving prints that are "muddy" and don't match your expectations, the culprit here is "colour management", not the file format. The bits and bytes you upload to the internet are going to be the same ones that arrive at the print shop; the problem is whether they are "interpreted" correctly. ...

JPEG is lossy, so the image loses some detail, but the file size may be smaller and compression and extraction can be faster. Wikipedia states, "[It] somewhat reduces the image fidelity... JPEG is also not well suited to files that will undergo multiple edits, as some image quality will usually be lost each time the image is decompressed and recompressed." ...

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).
