I'll not flood you with links, rather I'll dish them out a few at a time over coming posts.
Here's the first few.
Converting to Black and White — The BasicsThis one comes from the famous Cambridge In Colour website. Read the tutorial.
TLR SharpeningThis is a free Photoshop add-on from the Light Is Right Studio, one I pretty much always use — especially the capture sharpening mode.
It also has a mode for creative sharpening and one for output sharpening (where you set the sharpening specifically for the size you are printing at and the output device to be used).
Here's the download page.
There are some great quick tips at The Light Is Right Studio, in the form of short tutorials. Check them out here.
