Once upon a time (early to mid-century), bridal portraits were taken about a month before the actual wedding day. It was always a solo picture of the bride either in her home or a studio setting, and usually published in the local papers post-wedding. These days the bridal ports sync with all the wedding day photos--first look, getting ready, groomsmen, etc.
The above I captured of the photographer shooting the bride in a very special moment just after she was primped and primed, the below was shot by the above photographer Hayden Housini.
