I am shooting in Raw... I thought if you shot 8 bit vs 16 bit you had a wider range of colors because of the number of colors available (but it was exponential and not twice as many) perhaps I've mistaken.
First of all, your choice of color space in the camera does not actually matter if you shoot Raw, and also has nothing to do with 8-bit of 16-bit.
A jpeg will be 8-bit and will be in whatever color space you set it to.
[QUOTERaw is actually only actually 14 bit though, but 16 bits are available because of the nature of the way processors work - though I can't for the life of me remember why it goes 8, 16, 32, 64, 132, etc. etc... :P[QUOTE]
Raw files are, well, different when they are not processed. For older Canon cameras they are "12-bit", for newer bodies they are "14-bit", but everything changes when you convert a Raw file to an RGB image, which is where you choose in Camera Raw to open/Save a file either as 8-bit or 16-bit. You can have a tiff or psd as either, but a jpeg will only be 8-bit. Either could be in the sRGB color space or the aRGB color space, 8-bit or 16-bit.
That is true - I would convert to RGB for many options, but had read (and perhaps misunderstood) that shooting in Adobe was best because I then had recorded the largest options and they might change in conversion but since I had all the data there for Adobe and recorded, when I had an output option that could take advantage of the Adobe colorspace the data was preserved to be able to provide the image in that format at its best quality. Is that misunderstood?
You're getting some terminology mixed up -- the choices in the camera are between sRGB and AdobeRGB. If you are shooting jpegs they will both be in 8-bit formats. In camera Raw (since you are shooting Raw) the image will be rendered initially as a 16-bit RGB file and you will be "working in" a color space that Camera Raw is set in -- the link below your camera Raw preview will show this as a "preference". It will also show you whether you will be 16-bit of 8-bit when you open the image in the Elements editor.
Color space is the amount of tones you have to work with - there are different maps that have some overlay that is equal but there are different "fringe tones," so to speak - color that are available to one color space and not the other.
It is true that the different color spaces have different "gamuts". The common sRGB and aRGB have different gamuts. sRGB is the "universal" color space that monitors, systems, viewing software and Web browswer are all able to handle. Adobe RGB (aRGB) is a "wider" color space that contains some brighter, more saturated colors. Yes, there are instances when you may want to use aRGB, but it will only help if you are working with those colors and have a way of "presenting" them -- a monitor that has a wide gamut and/or a printer that can handle the wide gamut.
The number of bits recording them, I thought, actually limited how much you said about the color you were recording - more bits mean more information about the color, regardless of the color space it was in.
I had thought that if I had it left in Adobe colorspace in Elements it wouldn't LET me have an 8 bit depth, only allowed me to keep it at the 16(14) bit depth. As I said, I might be mis-remembering. Only recently have I begun using Elements that much and it was something I remembered from first working with it, so it could have been another operator error at the time that made me get things a little confused.
The "bit depth" is another issue from the color space. The color space determines the "gamut" or range of colors, and like I said, there are some instances where a wider gamut like aRGB can be useful, although for general presentation, such as the Web, sRGB is preferred. So if you are using aRGB to process images, there is no harm there, but for most output you'll want to output/convert to sRGB.
Bit depth is different -- it affects how you can adjust your overall tones within whatever color space you are in. But, as we've said, since you are shooting Raw you can maximise your use of 16 bits in Camera Raw and for most uses just convert to 8 bits in the Elements editor.
As to layers iin Elements, I don't recall having to go 8 bits to use layers, and then I haven't used Elements since version 4 so I don't know what you can do. I also don't recall having to convert from, say, aRGB to sRGB. But for some things you do have to convert to 8 bits. And, for general output, you want to convert to sRGB.
As to color space, check your Camera Raw settings. Check the link below the preview -- does it show sRGB or aRGB? You should know what you are doing there!
