DPP is an excellent S/W package and it is free....

Also look before you snap....! You your eyes, which sometime will fool you, and also your feet, to walk around before you snap to maybe snap from a different PoV. For BW, shoot in colour, and convert to BW. It's been discussed many times the pro and con of setting the camera to BW and using the pic. I've come to the conclusion shooting in colour works best for and than do the conversion. I do not use the grayscale feature. There are various post processions out there on the Web. Try them all using the same image to see which you like. The Lab processing works great.
