First of all, use Ilford XP-2 Super or Kodak TMAX-400CN film. Both of these are what are know as "chromogenic" black and white films, meaning that they can be processed along side color negative film at any drug store/supermarket minilab.

Take the film to the lab of your choice, and request "process only." The cost should be very low-I think that Walmart charges about $2 to do this at their in-store 1 hour lab. What will be returned to you is a strip of negatives.

Then, invest in either a film scanner, or a good flatbed scanner which can scan negatives.

Once you've scanned the images, you are free to post process/edit them in Photoshop or any other editing program of your choice.
