An old trick is to view your subject through a dark green filter- that gives you an idea of how the subject will look in black and white. Another way is to look in a brown filter, it gove similar effect but better suitable for street photography.
If you like to shoot black and white, try to use a green filter on the camera when working out of doors. It gives a healthy flesh tome and lightens dark green foliage so that dark suits and hair does not merge with the background. A light yellow filter when used in a (flash) portrait set up, produces pearly skin tones in portraits of the bride- combine that with a bit of soft focus and you have a wonderful effect.

I had the idea for several month, but there was some resistance to put much effort into it and the thought that actually doing photography as a business will kill the pleasure I have from doing it. So the my way to the business was slow, but yesterday I decided to get a tighter grip on the idea and start doing something in this direction.
My first step was to plan the whole thing, which lead me to creating a business plan. I searched the internet and found several resources to learn about the beast:

• Small Business Administration
• Small Business and Self-Employed One-Stop Resource (IRS) - added
• Business in DC (Washington DC government website) - added
• Dan Heller's Business Articles
• "Focus on Profit" Book and PhotoByte Software
• The Business of Photography - list of interesting books
• Business Articles on NYIP
• The Photographer's Guide to Marketing and Self-Promotion
• Sales and Marketing Articles
• Starting a Home Based Business - articles
• Sample Business Plan for Photography related business

Well, I am just on the second page of my business plan. I will post more of the ideas and thoughts on the topic. I better get back to writing the business plan ;)
