Most contracts stipulate that the photographer owns the rights to all photos taken at the wedding, even the ones of you. In other words, the photographer can use them promotionally (on their website or blog, submit them for publication and even place them in ads). That also means you can't just post the digital proofs they send you—most photographers have a policy that you can only share watermarked images or images with their credit on them. Also, unless you negotiate otherwise, if you want to print the images yourselves or order an album from another source, you'll have to buy the rights to the images.
With landscape photography, time of day is absolutely imperative. 95% of the landscape photos in my portfolio of the best shots I've ever taken were photographed in the very early morning at sunrise or late in the evening at sunset. Beginning photographers often overlook this important tip and try to make a photo in the middle of the day. That's rarely a recipe for success.
There are a few bonuses to using accessories well (as well as layers). One is that changing them up a bit throughout the session can give you multiple looks without having to do many wardrobe changes. They can also be something that the subjects can interact with. A sassy little tip of the hat, holding the ends of a scarf while running and letting it billow behind you, grabbing the lapels of a husbands jacket while pulling him close for a kiss – all these little gestures and ways to interact (and become more comfortable in front of the camera) can be made possible with styling choices. Many of my sessions will feature items used outside their intended use or subject. My girls are often seen in mommy’s hats or scarves (scarves can be used in different ways like wrapped around their shoulders, as a hair piece, etc) and they love to wear my costume jewelry.
