John Gray's bestselling book used a planetary analogy to understand relationships. It proved very popular as a way of understanding and interpreting behaviour patterns that men and women display.

Astrology also uses planets to understand and predict character traits and behaviour patterns. It is an extremely effective tool for analysing relationships. Venus and Mars are not only planets looked at, although they are important. In total there are ten planets to consider and 12 different signs that each planet could be in. This gives a very high number of possible combinations, which can lead to an insightful and detailed analsis.

One of reasons astrology is such a useful tool is its neutrality. By describing a relationship astrologically, a distance can be achieved. Difficulties then become a shared problem which could be resolved through co-operation. Identifying problem as 'We have a Mars opposition' is a much more neutral way of saying 'We argue all time' or even ' Why do you always argue with me?' What's more, astrology can even help to identify timing of both good and difficult times. Knowing that things will get better can dissolve a lot of tension.

In any relationship there will be combinations of harmonious and challenging aspects, but there will often be a way of relating to each other that seems to work most of time. It becomes a habitual way of interacting, line of least resistance. Sometimes one particular planet provides a dominant theme for relationship. In effect, it is planet on which relationship is based.

Most photographers will be sure to include parents in photos with bride and groom, but most will never think to inquire about doing groups of individual dads of bride or groom with all his brothers and sisters who are present at wedding. And of course, same is true with individual moms of bridal couple, too.

While you're getting these photos taken, be sure to include any parents and grand-parents of those brothers and sisters that are there, too, to capture their entire core family group in photos.

A wedding is almost perfect place to take these kind of photos with individual parents and their siblings. Everyone in families has gathered for big event, many times from far flung regions of country.

Their child's wedding may well be first time brothers and sisters have gotten together in years. It may be many years in future before they are ever together again. If opportunity to take these group photos is passed over because nobody thought much about importance of this fleeting opportunity, then those photos may end up never being captured. These photos often turn out to be most important and most appreciated of all photos I take regularily at wedding.

I'd be willing to bet that less than 10 percent of wedding photographers plying their trade today know to get these photos for you. You will have to specifically ask for them to be taken, or they just won't be done!

Other important people that most photographers will probably overlook photographing for you at wedding, unless you give them your written photo request list, are bride and/or groom's god parents, groups of bride and/or groom's co-workers, high school friends, youth camp friends, fellow fraternity and sorority members, fellow sports team members for high school or college.

The one thing no wedding photographer can do is look at a room full of total strangers and figure out how they interlock with each other just by looking! I gave up trying to do that after photographing my very first wedding 40 years ago! Now I send each bride an email before wedding requesting exactly this sort of information, so that I don't end up missing anyone of importance to bridal couple on their special day.
