Below is how I save photos from raw to web. (sorry this is a quick rough draft, will refine later, hope you can understand it)

First I open a raw file in Photoshop:

Opening a Raw file in Photoshop automatically opens it in 'Camera Raw'. I edit the photo here until I'm satisfied. Do note the red circle above. I work in Adobe RGB which is apparently best for prints. You can change the colour profile to what you would like to work in by clicking on the link. I mostly work with 300ppi, but for now 240ppi suites my needs.

When you are done editing in raw then click [Open Image] which opens the photo in Photoshop for further editing. When I'm done editing I then save my photo as a Tiff file. TIFF is an image file format that does not lose any quality when it is saved, unlike jpeg which compresses the image and throws away pixels which it deems unnecessary. (NOTE: If you choose SAVE then you may overwrite your orginal file, so I always choose SAVE AS to avoid this mistake)

File>Save As

There is a pop up box where you have choices, but I don't change anything in the Tiff file. I just leave it as it is.

Now I have a Tiff file saved of my image which is my final image. This is perfect for printing, but if you are taking it or sending it to be printed they will probably want a jpeg file. I resave this as the highest quality jpeg file possible. (will include explanation later)

To now save this for web use we need to first change the colour profile to sRGB. If we don't then we will see a colour change in our images on the web that we might not like. Here is how to change the colour profile.

Edit>Convert to Profile

As you can see above the Source Space is Adobe RGB, and I want to change the Destination Space to sRGB for web use. click OK.

Now you have an image with the correct colour profile for internet use but it is far too large. So now we change the size.

Image>Image Size

In the Image Size 1 window above you see the size of the photo. We want to change this to a usable photo for the web. So in the Image Size 2 window I've made sure the Constrain Proportions and Resample Image boxes are checked. Then I've changed the Resample choice to Bicubic Sharper. Then I changed the Resolution from 240 to 72ppi, which is all you need for web use. I then change the longest side, which is the Height in this case, to 700 pixels. I rarely use more than 800pixels wide. Much more than that is too large to view on most screens. OK.

Now I have an image the correct size for web use, now I save it as a Jpeg.

File>Save As

Here I've saved as a Maximum quality jpeg as I'm not worried about the file size so much. You can also save as Low, Medium and High. The screen shot above was saved on Medium quality. For most web use High quality is all you need.

Saving in this manner will keep your file information in tact, like the camera used and info from the camera on how it was shot. You can also add to this information your details and other things. Another tutorial I think.
