What resolution should I choose when scanning?
This depends on the size of the original image and the desired size and intended use of the restored image. Obviously, the better the original image/scan the better the end result, so it is important to start with a quality scan.
Consider what you plan to do with your restored image. Do you wish to enlarge it? If so, you should consider the maximum size you may wish to print your image now, before you scan.

You scanner may not allow you a wide choice of scanning resolutions. If not, choose the option closest to the recommended resolution
Even if your image will only be used for web publication or for email or web publication, it is wise to scan it at a minimum of 600 ppi. You can easily reduce the size of an image file, but it is difficult to make an image larger without seriously compromising the quality of the image. The extra data also makes it easier for us to provide a quality restoration.
My scanner allows me to choose from greyscale or RGB. Which setting should I use for black and white images?
Scan all images in RGB (red, green, blue), regardless of whether they are black and white, sepia or colour.
Information potentially useful for restoring monochrome images can be extracted from the individual RGB colour channels.
Take a moment to read this blog post I posted on my blog a few years ago. It clearly demonstrates the advantage of scanning in colour instead of grey scale. That colour data can sometimes save me hours of restoration work, which, in turn can save you money.
What file type should I save?
When saving your files, choose TIFF if possible. This is a lossless file format allowing the best possible quality.
If your scanner does not give you the option of saving your files as tiffs, jpeg is the next best option.
