Packages are generally less expensive up front and more expensive for extras such as prints and albums. Photojournalistic style photographers tend to take considerably more pictures since their style is based on capturing the wedding story and are generally more expensive up front. This can also be affected by the price of the packages. Some photographers will limit their coverage to reduce expenses. With today's technology, negatives do not have the value they once did, but it is important to know what will become of them if you do not or are not able to purchase them.
Some photographers try to contract more than one wedding or other event in a single day.
This could make them unavailable for sudden changes in schedule. There may be additional fees if the photographer is required to stay beyond the contracted time or required to be available for sudden changes. Ask to see an album of a complete wedding if one is not presented. This will give you a better feel for the quality of the photography in different situations during the same wedding rather than an album of the best photography from different weddings. Get to know your photographer.
