Typically, I guess most people are using Photoshop (you can download a 30 day trial from adobe.com BTW). The easiest way to do it in PS is from the Image menu, select Mode and choose Grayscale. BUT, a more controllable method is to go to the Image menu, select Adjustments, choose Channel Mixer, tick the Monochrome box, and then adjust with the sliders, that way you can get the levels of contrast and tone you want, but bear in mind that doing it this way will not change the mode, it will merely drop all the colour data out of it (so it will still be an RGB image), so you might then want to manually change it to a grayscale with the first method suggested. Unless you want to try this....

The easiest way to get a 'sepia tone' image is to create a grayscale image in one of the above ways, but keep the image in RGB mode and then add a new layer from the layers palette (on the right). When you've done that, select a beige colour from either the swatches palette or by double clicking on the foreground colour at the bottom of the left hand toolbox and picking a suitable colour. When you've got a good sepia colour, choose the paintbucket tool (it may be behind the gradient tool on the toolbox, click and hold to switch tools) from the toolbox and click in the image area, it will initially flood the image with a solid colour, but go to the layers palette on the right and change where it says Normal, to something like Overlay or Multiply and play with the opacity slider just to the right, until you have what you want. Then try flattening the image from the Layer menu and going to the filters menu and selecting Noise, Add Noise, or maybe Despeckle.

Note that you have to flatten an image to be able to save it in several of the modes, otherwise you'll be limited to saving a layered file in either PSD or TIFF format (and one or two other wierd ones). For more info, do a search on google or yahoo for 'Graphic Formats Wiki', this will take you to a wikipedia page which explains most picture file formats and what they support.

Have fun.
